However, none of the CZOs within the network occur in landscapes underlain by carbonate bedrock (which cover about a quarter of Earth\u2019s land surface), limiting the development of a holistic understanding of CZ processes.<\/p>\n<p>This project creates a Carbonate Critical Zone Research Coordination network (RCN) that aims to integrate transdisciplinary investigators studying disparate carbonate-rich CZ\u2019s and foster collaboration among these investigators and existing CZO network participants. To do so the project will:<\/p>\n<p>(1) Compile available data and models stemming from current research to identify critical knowledge gaps and develop forward-looking research questions and testable hypotheses.<\/p>\n<p>(2) Convene workshops, in the field and at major disciplinary conferences.\u00a0 Three field workshops will occur in distinct carbonate regions that cross gradients of rock age, climate, and tectonism and will integrate across disciplinary boundaries.\u00a0 Two conference workshops will focus on specific disciplines associated with the particular conference (e.g., geological, hydrological, ecological) and will include special sessions and roundtable discussions across multiple carbonate CZs.<\/p>\n<p>(3) Build capacity in state of the art techniques used to study carbonate CZs within the broad CZ scientific community.<\/p>\n<p>(4) Use data compilation, workshop participation, and training to advance understanding of properties and processes across all CZs.<\/p>\n<p>Outcomes of this RCN will include improved understanding of how relative amounts of carbonate and silicate minerals may cause different CZ properties and processes between regions.\u00a0 Human capital will be developed through research collaborations created during workshops and through training.\u00a0 Participants will be recruited to project activities with a focus on diverse disciplinary expertise, research geographical area, career stage, and demographics.\u00a0 A special effort will be made to increase diversity of participants via members of the steering committee who have interests in expanding inclusivity and by outreach to sections of various major societies aimed at increasing inclusivity along with various smaller societies with primary missions of fostering diversity in STEM fields.\u00a0 Outcomes will be disseminated among the CZ research community through workshop reports, a series of three peer-reviewed papers, and the project website.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<footer class=\"footer-wrapper\">\n<div class=\"footer-container container\">\n<div id=\"footer-widget-2\" class=\"footer-column four columns\">\n<div id=\"text-5\" class=\"widget widget_text limoking-item limoking-widget\">\n<div class=\"textwidget\">\n<p>&nbsp;<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/footer>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t<div class=\"sow-accordion-panel\n\t\t\t\t\t\"\n\t\t\t\tdata-anchor-id=\"modeling-karst-conduit-evolution-and-flow-and-transport-behavior\">\n\t\t\t\t\t<div class=\"sow-accordion-panel-header-container\" role=\"heading\" aria-level=\"2\">\n\t\t\t\t\t<div class=\"sow-accordion-panel-header\" tabindex=\"0\" role=\"button\" id=\"accordion-label-modeling-karst-conduit-evolution-and-flow-and-transport-behavior\" aria-controls=\"accordion-content-modeling-karst-conduit-evolution-and-flow-and-transport-behavior\" aria-expanded=\"false\">\n\t\t\t\t\t\t<div class=\"sow-accordion-title sow-accordion-title-icon-left\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\tModeling Karst Conduit Evolution and Flow and Transport Behavior\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"sow-accordion-open-close-button\">\n\t\t\t\t\t\t\t<div class=\"sow-accordion-open-button\">\n\t\t\t\t\t\t\t\t<span class=\"sow-icon-ionicons\" data-sow-icon=\"&#xf218;\"\n\t\t \n\t\taria-hidden=\"true\"><\/span>\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"sow-accordion-close-button\">\n\t\t\t\t\t\t\t\t<span class=\"sow-icon-ionicons\" data-sow-icon=\"&#xf209;\"\n\t\t \n\t\taria-hidden=\"true\"><\/span>\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\n\t\t\t<div\n\t\t\t\tclass=\"sow-accordion-panel-content\"\n\t\t\t\trole=\"region\"\n\t\t\t\taria-labelledby=\"accordion-label-modeling-karst-conduit-evolution-and-flow-and-transport-behavior\"\n\t\t\t\tid=\"accordion-content-modeling-karst-conduit-evolution-and-flow-and-transport-behavior\"\n\t\t\t\tstyle=\"display: none;\"\t\t\t>\n\t\t\t\t<div class=\"sow-accordion-panel-border\">\n\t\t\t\t\t<p><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-385\" src=\"https:\/\/waterinstitute.ufl.edu\/faculty\/graham\/wp-content\/uploads\/DSC_0365-e1531751808450-1024x382.jpg\" alt=\"\" width=\"1024\" height=\"382\" srcset=\"https:\/\/waterinstitute.ufl.edu\/faculty\/graham\/wp-content\/uploads\/DSC_0365-e1531751808450-1024x382.jpg 1024w, https:\/\/waterinstitute.ufl.edu\/faculty\/graham\/wp-content\/uploads\/DSC_0365-e1531751808450-300x112.jpg 300w, https:\/\/waterinstitute.ufl.edu\/faculty\/graham\/wp-content\/uploads\/DSC_0365-e1531751808450-768x287.jpg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<p style=\"text-align: right;\">photo by Jennifer Adler<\/p>\n<p style=\"text-align: left;\"><strong>Sponsor:\u00a0<\/strong>Carl S.

Lake Okeechobee is the main location for surface water storage in this system.\u00a0 As part of the Central and Southern Florida (C&amp;SF) Project authorized in 1948 the system was engineered with two large canals that now have the capacity to carry large volumes of water from Lake Okeechobee to the St. Lucie and the Caloosahatchee estuaries. Considerable impacts to the natural ecosystems of south Florida, including the St. Lucie Estuary,\u00a0 Caloosahatchee Estuary, Lake Okeechobee, and the Florida Everglades stem from large deviations in the quantity and quality of freshwater delivered to these systems relative to a pre-engineered time period. Lake Okeechobee is regulated and managed by the U.S. Army Corps of Engineers (USACE) in collaboration with SFWMD who provides information. Currently, they are planning a lake regulation review that will consider alternative regulation schedules that take into consideration the tradeoffs between health of the lake, estuaries, Everglades, as well as provision of flood control and water supply.<\/p>\n<p>This project aims to to conduct an independent scientific review to help inform the development of the next Lake Okeechobee Regulation Schedule.

South West Florida, which includes the heavily populated Tampa Bay area, arguably has the most intense competition for water resources among urban, agricultural and ecological users, as well as significant vulnerability to floods, droughts, and and long-term climate change. The major water resource decision makers in this area are Tampa Bay Water, the largest public water supplier in the region, and the South West Florida Water Management District, which has the responsibility of issuing permits to local and regional governments, agriculture, and other users of surface and aquifer water sources. In this research we will develop and implement a prototype modeling system that provides multi-decadal climate forecasts and predictions for use in Tampa Bay Water's water resource decision making processes. A variety of dynamical and statistical Global Climate Model (GCM) downscaling techniques will be developed and evaluated for the Tampa Bay Region. The most successful techniques will be used to drive Tampa Bay Water's Integrated Hydrologic Model to determine potential impacts of multi-decadal climate varaibility and climate change on water supply reliability in the region.<\/p>\n<hr \/>\n<h3><strong>Available Outputs<\/strong><\/h3>\n<p><strong>Title:<\/strong> <a href=\"http:\/\/journals.ametsoc.org\/doi\/abs\/10.1175\/2011JHM1309.1\" target=\"_blank\" rel=\"noopener\">Quantitative Spatiotemporal evaluation of dynamically downscaled MM5 precipitation predictions over the Tampa Bay region<\/a>, Florida, J.

Our overarching hypothesis was that strong coupling between riverine hydrology and biogeochemistry yields a suite of natural tracers that, when measured at temporal densities concordant with water fluxes (i.e., daily or sub-daily), can yield new insights into riverine source water and mixing dynamics. To enhance understanding of the dynamic coupling between watershed elemental budgets and hydrologic variability we proposed a suite of high temporal resolution measurements of these solutes coupled with improved quantification of riverine mixing from natural tracers. Moreover, we predicted that this new information on surface water-groundwater mixing in rivers would allow improved model conceptualization and parameterization that will increase prediction accuracy of in-stream, and near-stream hydrologic chemical fluxes.<\/p>\n<p>We proposed three coupled science and engineering questions: 1) What are the temporal and longitudinal dynamics of surface-groundwater mixing, and how do these affect the delivery of ecologically relevant solutes (nitrate, phosphate, H+, dissolved organic carbon)? 2) To what magnitude, and over what spatiotemporal domain, does assimilation of high resolution stream chemistry data into integrated, parallel watershed models (e.g., PARFLOW) improve predictions of stream flow, groundwater elevation, surface\/groundwater mixing and solute transport?3) To what extent are real-time predictions of stream flow and surface\/groundwater mixing ratios improved when Bayesian network models incorporate high resolution stream chemistry measurements and process model predictions along with mission agency data?<\/p>\n<h3><strong>Available Outputs<\/strong><\/h3>\n<hr \/>\n<p><strong>Title:<\/strong> <a href=\"http:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/2013WR013991\/abstract\" target=\"_blank\" rel=\"noopener\">Characterization of groundwater and surface water mixing in a semi-confined karst aquifer using time lapse electrical resistivity tomography.

In this research project legacy hydrologic, meteorologic and water quality data from the Santa Fe basin in the Suwannee river watershed were assembled into a web-accessible digital watershed. These data, together with predictions from physically-based hydrologic models, were used to develop a probabilistic algorithm to predict surface water stage and flux throughout the Santa Fe river basin and evaluate the accuracy of these predictions. Information on prediction uncertainty was used to design a spatial network of new conductivity-temperature-depth (CTD) sensors to improve the predictions. The adequacy of the assembled data and the utility of the optimal estimation algorithm was\u00a0 evaluated by comparing resulting predictions with observations of surface water stage and flux from the newly deployed CTD sondes.<\/p>\n<p>In addition, off-the-shelf optical and cadmium reduction continuous nitrate sensors were deployed at selected locations in the Santa Fe watershed to develop improved local relationships among flow, stage, conductivity and nitrate. This new knowledge laid\u00a0 the groundwork for developing a general methodology to augment continuous measurement of nitrate with correlated surrogates (i.e., in this case flow and conductivity) to decrease the density of sensors needed to accurately predict the nitrate in the system over space and time. Furthermore, the data laid the groundwork for developing improved understanding of the chemical and physical controls of nitrate and water fluxes through watersheds required to address science questions that could be answered with previously available data sampling and monitoring programs.<\/p>\n<h3><strong>Available Outputs<\/strong><\/h3>\n<hr \/>\n<p><strong>Title:<\/strong> <a href=\"http:\/\/ieeexplore.ieee.org\/stamp\/stamp.jsp?tp=&amp;arnumber=4778977\" target=\"_blank\" rel=\"noopener\">A Method for Measuring the Incremental Information Contributed from Non-Stationary Spatio-Temporal Data to Be Fused, doi: 10.1109\/IGARSS.2008.4778977, vol. 2, pp. II-261 - II-264, Proc.

Statistical trend, correlation and cluster analyses of these data were conducted on time series that had more than 10 years of consistent data within the January 1980 to December 2007 study period.<\/p>\n<p>Results from statistical trend analyses showed that 12 out of 132 groundwater wells had statistically significant downward trends at the 95% confidence level for the 1980-2007 time period. For the rainfall data, 1 out of 44 stations had a statistically significant downward trend at the 95% confidence level for the 1980-2007 time period. No statistically significant trends were detected for the 22 streamflow stations over the study period. There was insufficient spring flow data (i.e., less than 10 years of observations with sporadic measurements) to conduct the statistical analyses.<\/p>\n<p>Uncertainty regarding the accuracy of the groundwater withdrawal records compiled, and conflicting results from the various statistical trend analyses of these records, suggest that these groundwater withdrawal data were not of sufficient quality to draw reliable conclusions about trends in these data or correlations with groundwater level trends.<\/p>\n<p>In the supplement report, the entire period of record for historic groundwater levels (upper Floridan) data in the Suwannee River basin and northeast Florida were analyzed for long-term trends and cluster analysis. In the final report under the original contract, groundwater level data available prior to 1980 was neglected since other time series of interest (principally groundwater withdrawal estimates) were not consistently available before then.<\/p>\n<h3><strong>Available Outputs<\/strong><\/h3>\n<hr \/>\n<p><strong>Title:<\/strong> <a href=\"https:\/\/waterinstitute.ufl.edu\/faculty\/graham\/wp-content\/uploads\/final_report2.pdf\" target=\"_blank\" rel=\"noopener\">Statistical Evaluation of Hydrologic Data in Northeastern Florida and Southern Georgia: Final Report<\/a><br \/>\n<strong>Authors:<\/strong> Gao, B., McKee, K., Gargiulo, O. and W.

The lake provides regional flood protection, water supply for agricultural, urban and natural areas, and is a critical habitat for fish, birds and other wildlife, including the federally endangered Everglades Snail Kite. The 1997 Lake Okeechobee Surface Water Improvement and Management (SWIM) Plan found that excessive phosphorus loading is one of the most serious problems facing the lake. Frequent algal blooms, detrimental changes in biological communities, and impaired use of the water resources are among the documented adverse effects of excessive phosphorus loading. The purpose of this interdisciplinary research project is to reduce phosphorus loadings to Lake Okeechobee from Beef Cattle Ranches by developing Best Management Practices (BMPs) and implementing them at the ranch scale. Pre- and post-BMP surface and groundwater monitoring will be conducted to evaluate the effectiveness of the BMPs at improving surfacewater quality while maintaining acceptable productivity. The data collected will be used in the development of computer models that simulate the impacts of various BMP alternatives, and assist landowners in choosing the most cost-effective BMPs to implement<\/p>\n<h3><strong>Available Outputs<\/strong><\/h3>\n<hr \/>\n<p><strong>Title:<\/strong> <a href=\"https:\/\/waterinstitute.ufl.edu\/faculty\/graham\/wp-content\/uploads\/p34866_rew_thesis.pdf\" target=\"_blank\" rel=\"noopener\">Aluminum Water Treatment Residuals for Reducing Phosphorus Loss From Manure-Impacted, High-Watertable Soils (pdf)<\/a><br \/>\n<strong>Authors:<\/strong> Rew, T.

The data collected will be used in the development of computer models that simulate the impacts of various BMP alternatives, and assist landowners in choosing the most cost-effective BMPs to implement.<\/p>\n<h3><strong>Available Outputs<\/strong><\/h3>\n<hr \/>\n<p><strong>Title:<\/strong> <a href=\"https:\/\/waterinstitute.ufl.edu\/faculty\/graham\/wp-content\/uploads\/WM811_Final_Report_7-10-2008.pdf\" target=\"_blank\" rel=\"noopener\">Evaluating Effectiveness of Best Management Practices for Animal Waste and Fertilizer Management to Reduce Nutrient Inputs into Ground Water in the Suwannee River Basin<\/a><br \/>\n<strong>Authors:<\/strong> Graetz, D.A.<\/p>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t<div class=\"sow-accordion-panel\n\t\t\t\t\t\"\n\t\t\t\tdata-anchor-id=\"evaluation-of-the-impacts-of-alternative-citrus-production-practices-on-groundwater-quality\">\n\t\t\t\t\t<div class=\"sow-accordion-panel-header-container\" role=\"heading\" aria-level=\"2\">\n\t\t\t\t\t<div class=\"sow-accordion-panel-header\" tabindex=\"0\" role=\"button\" id=\"accordion-label-evaluation-of-the-impacts-of-alternative-citrus-production-practices-on-groundwater-quality\" aria-controls=\"accordion-content-evaluation-of-the-impacts-of-alternative-citrus-production-practices-on-groundwater-quality\" aria-expanded=\"false\">\n\t\t\t\t\t\t<div class=\"sow-accordion-title sow-accordion-title-icon-left\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\tEvaluation of the Impacts of Alternative Citrus Production Practices on Groundwater Quality\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"sow-accordion-open-close-button\">\n\t\t\t\t\t\t\t<div class=\"sow-accordion-open-button\">\n\t\t\t\t\t\t\t\t<span class=\"sow-icon-ionicons\" data-sow-icon=\"&#xf218;\"\n\t\t \n\t\taria-hidden=\"true\"><\/span>\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"sow-accordion-close-button\">\n\t\t\t\t\t\t\t\t<span class=\"sow-icon-ionicons\" data-sow-icon=\"&#xf209;\"\n\t\t \n\t\taria-hidden=\"true\"><\/span>\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\n\t\t\t<div\n\t\t\t\tclass=\"sow-accordion-panel-content\"\n\t\t\t\trole=\"region\"\n\t\t\t\taria-labelledby=\"accordion-label-evaluation-of-the-impacts-of-alternative-citrus-production-practices-on-groundwater-quality\"\n\t\t\t\tid=\"accordion-content-evaluation-of-the-impacts-of-alternative-citrus-production-practices-on-groundwater-quality\"\n\t\t\t\tstyle=\"display: none;\"\t\t\t>\n\t\t\t\t<div class=\"sow-accordion-panel-border\">\n\t\t\t\t\t<p><strong>Sponsor<\/strong><br \/>\nFL Department of Agriculture &amp; Consumer Services<\/p>\n<p><strong>Award Dates<\/strong><br \/>\n7\/1\/1992 - 12\/31\/2004<\/p>\n<h3><strong>Participants<\/strong><\/h3>\n<hr \/>\n<p><strong>Project Lead<\/strong><br \/>\nGraham, Wendy Dimbero<\/p>\n<h3><strong>Goals and Objective<\/strong><\/h3>\n<hr \/>\n<p>In some agricultural regions of Florida, the frequency of drinking water wells contaminated by nitrate nitrogen exceeds the national frequency found in the EPA survey conducted in 1990. Of 3,949 drinking water wells analyzed for nitrate-nitrogen by the Florida Department of Agriculture and Consumer Services (FDACS) and the Florida Department of Environmental Protection (FDEP), 2,483 (63%) contained detectable nitrate-nitrogen and 584 (15%) contained nitrate-nitrogen above the EPA MCL. Of the 584 wells statewide that exceeded the MCL, 519 were located in the Central Florida Ridge citrus growing region, encompassed primarily by Lake, Polk, and Highlands Counties.<\/p>\n<p>The goals and objectives of this research project were to: (1) generate baseline groundwater nitrate data from several commercial citrus groves in the Central Florida Ridge region in order to relate current groundwater nitrate trends to existing and historic management practices; (2) develop recommendations for alternative nutrient and water management practices for each cooperator site intended to reduce off-site groundwater nitrate impacts associated with citrus production; and (3) assess the impacts of alternative management practices on groundwater nitrate-nitrogen through comprehensive monitoring and modeling.<\/p>\n<h3><strong>Available Outputs<\/strong><\/h3>\n<hr \/>\n<p><strong>Title:<\/strong> <a href=\"https:\/\/waterinstitute.ufl.edu\/faculty\/graham\/wp-content\/uploads\/lamb_et_al_2000.pdf\" target=\"_blank\" rel=\"noopener\">Impact of Alternative Citrus Management Practices on Groundwater Nitrate in the Central Florida Ridge: I.
