A continuous hydrologic model (HEC-HMS) was developed and will be used to evaluate a water diversion for wetland creation in Evansville, IN. Continuous hydrologic models require continuous tracking of soil moisture changes. This requires vapor loss to the atmosphere via evapotranspiration (evaporation plus transpiration) to be modeled. Two methods were used to calculate evapotranspiration using 20 years of historic meteorological data. Field data was collected to aid in validation of the HEC-HMS model. This required installation of a staff gauge and a water level measurement station. The validated model will be used in future storage routing calculations to design a culvert to divert water towards the center of the site. A hydraulic model (HEC-RAS) developed by a previous capstone design team was also used to aid storage routing calculations with HEC-HMS. In addition to the developed model, water quality analysis was conducted to reinforce the objective of improving water quality at the site. The results from the model will provide estimates of water diversion quantities achievable over a wide range of meteorological conditions.
