A Regionalized Flow Duration Curve Method to Predict Streamflow for Ungauaged Basins: A Case Study of the Rappahannock Watershed in Virginia, USA
MOHAMOUD, Y. M. AND R. S. PARMAR. A Regionalized Flow Duration Curve Method to Predict Streamflow for Ungauaged Basins: A Case Study of the Rappahannock Watershed in Virginia, USA. Presented at Joint IAHS & IAH International Convention, Hyderabad, INDIA, September 06 - 12, 2009.
A method to predict streamflow for ungauged basins of the Mid-Atlantic Region, USA was applied to the Rappahannock watershed in Virginia, USA. The method separates streamflow time series into magnitude and time sequence components. It uses the regionalized flow duration curve (RFDC) to predict the magnitude component and uses the time sequence of a nearby gauged site to estimate the time sequence component. We evaluated the performance of the RFDC method for predictions in ungauged sites by comparing RFDC streamflow predictions from several ungauged sites with observed streamflow from nearby gauged sites. In addition, we compared RFDC streamflow predictions with streamflow simulated for the ungauged sites by the Hydrologic Simulation Program Fortran (HSPF).
To conduct hydrology and water quality process studies to enhance process representations in watershed models.
