  Estimating water yield from pine forests with different understory management strategies
  Forests play an important role in maintaining proper water balance of an area by affecting different hydrologic components such as evapotranspiration (ET), runoff and storage. However, studies on how variations in forest management strategies affect overall water yield are generally lacking. In this study, we use soil water balance to estimate water yields under a range of understory management regimes in pine forests across Florida. Using the in-situ soil-moisture and groundwater level measurements combined with the forest-stand attributes (leaf area index and basal area), stand-scale ET are estimated for forests subject to different understory management, and burning strategies. These ET estimates, combined with the annual rainfall data are then used to derive regional water yields for each management type. The results from these analyses will enable the development of general, management-water yield relationships which could be key to devising ideal forest management scenarios for better surface and groundwater resource management in the southeastern US.
