I-99 Environmental Research - Task B - Hydrologic Modeling and Monitoring

The primary objectives of Task B is to identify a watershed runoff model that would capture the special features of watersheds that are formed by highway construction and to use the model to monitor the impacts on surface and groundwater. After a comprehensive review of existing watershed models it was decided to develop a model which would satisfy Pennsylvania Department of Transportation (PENNDOT)’s requirements. The computer model was coded, calibrated and tested on two test watersheds. Both watersheds were instrumented with monitoring wells, water level recorders and flow measuring flumes which were used in conjunction with hydrometeorological data to determine how well the model performed. Data on precipitation data was provided by Skelly and Loy, Inc. Testing was carried out for several more months to cover a broad range of conditions. The tests show that the model preformed well and that it may be used by PENNDOT as hydrologic software support in assessing the impacts of future highway construction projects. Procedures in the modeling process are documented. Instrumentation requirements are identified and recommendations on instrumentation procedures are provided with a view of reducing future costs of monitoring the hydrologic variables in evaluating the environmental impacts of highway construction.
