Wetland Hydrology

ACTIVE PROJECTS

Wetbud – Wetland Water Budget Modelling Software development and promulgation.  Funded by the Peterson Foundation and Wetland Studies and Solutions, Inc.  Project Team includes Lee Daniels and Tess Thompson (VTech) and Zach Agioutantis (UKy).  WSSI Symposium on Wetlands Research:  http://wetlandstudies.com/resources-regulations/additional-resources/wriresources.html

Projects currently funded by WSSI to test Wetbud:

Julie Metz Mitigation Wetland.   Located adjacent to a fresh-water tidal creek in northern Virginia, the wetlands were constructed by regrading the toes of alluvial fans that transmit considerable quantities of groundwater to the sties.  Both Basic and Advanced Versions of Wetbud are being used to evaluate the contributions of tides and groundwater, and to evaluate the effects of future storm surges and sea level rise. Project Lead:  Ben Hiza.   Info about Julie Metz

Huntley Meadows Wetland Restoration.  The large wetland fringing a pond at this city park in Alexandria, Virginia grew when its (beaver) dam was replaced by a higher water control structure.  In order to understand how to apply Wetbud to this large andcomplex valley-bottom flat, we are assessing the local and regional hydrogeology of the site.  We are also comparing the differences in evapotranspiration (ET) calculated by several methods including Bowens Ratio and White’s hydrograph fluctuations.  Project Lead: Stephen Stone.

North Fork Mitigation Wetland.  This wetland sits on fine-grained sedimentary rocks of the Culpeper Triassic Basin and so is dominated by surface-water dynamics.  Instrumentation at this site will allow us to calibrate and verify the assumptions and calculations used in Wetbud for runoff, channel flow, and weir evaluation.  Project Leads:  Stephen Stone, Ben Hiza, Rachel Dunleavy.  Info about North Fork

Cape Henry Beach Ridge Complex.  This large cuspate foreland consists of numerous sandy beach ridges and eolian dunes interlaced with cypress swamps. Fresh-water wetlands form where the water table dome rises higher than the inter-dune swales, as much as 2 meters above sea level in the middle of the complex.  Ground water fluctuations over time will be estimated using Effective Monthly Recharge calculations based on nearly a century of weather data.  Crop coefficients for adjusting ET estimations will be calculated for cypress and pine forest settings.  Project Lead:  Bryce Shoup.
