There is growing interest for the installation of green stormwater infrastructure (GSI) to improve control, increase infiltration stormwater, and receiving water body quality. Planning level tools are needed inform municipal scale decisions on type extent GSI apply. Here, a modified methodology developed EPA Storm Water Management Model (SWMM) create SWMM Low Impact Technology Evaluation (SWWM-...

Basin hydrologic response is a function of soil moisture distributional featuresAn information-based dimensionless index of hydrologic complexity is appliedThe complexity index characterizes soil moisture distributional features.

In the present study, streamflow simulation capacities between Soil and Water Assessment Tool (SWAT) Hydrologic Engineering Centre-Hydrologic Modelling System (HEC-HMS) were compared for Huai Bang Sai (HBS) watershed in northeastern Thailand. During calibration (2007–2010) validation (2011–2014), SWAT model demonstrated a Coefficient of Determination (R2) Nash Sutcliffe Efficiency (NSE) 0.83 0....

We used a retrospective approach to identify hydrologic metrics with the greatest potential for ecological relevance for use as resource management tools (i.e., hydrologic indicators) in rapidly urbanizing basins of the Puget Lowland. We proposed four criteria for identifying useful hydrologic indicators: (1) sensitive to urbanization consistent with expected hydrologic response, (2) demonstrat...

Hydrologic models simulate the river flow from the contributing basin for a given river. For the simulation process, the integration domain is discretized into computational cells. The inputs for such models are precipitation ratio and the initial flow. There are many parameters to be determined for an operational model, including the type of soil (porosity field, water flux between the bottom ...

Many cities have been built along large rivers. The rivers can provide a source of drinking water, act as receiving water for treated effluent, provide navigation for shipping, and other beneficial uses. However, the city must also be protected from flooding due to the close proximity to the river. Hydrologic analysis plays a crucial role in the development of plans for protecting a river city....
