Abstract: New technologies have been developed to measure hydrologic processes of runoff, recharge and evapotranspiration (ET) in shallow water table environments characteristic of much of the Gulf of Mexico coastal plain. These environments are typified by west-central and southern Florida sedimentary riverine systems. However, limited testing in deeper or transitional hill slope; deep-to-shallow water table environments has been conducted to date. This proposed research is to test the methodologies developed at USF to measure hydrologic processes in a small ecological study area lying within the Hillsborough River watershed in west-central Florida. Continuous soil moisture an pressure monitoring along hill slope transects that encompass characteristically deep (greater than 2m) and shallow (less than 2m) water table depths and associated habitats will be conducted for a period of three years. Of interest is the dry/wet season and dry/wet year runoff, recharge and ET distributions for the transitional environment and especially the mover xeric (slash pine and scrub oak) habitats at this site. Results from this study will be critical new information and insight into magnitude and causative mechanisms of runoff, recharge and ET processes from these environments. Findings from the study should be of immediate importance and use to water management entities as well as provide useful paramertization and conceptualization of processes for emerging integrated surface and groundwater computer models of the region. After an initial first year testing period has elapsed, once or more additional suitable sites will be identified for measurements to gather replicate or comparable data to adequately characterize these environments.
