Description:
A physically-based methodology for streamflow forecasting is researched and implemented. Watershed response is modelled as Continuous-Time Markov process whose states include both surface and subsurface runoff components. Based on probabilistic arguments, time-varying Instantaneous Unit Hydrographs are derived and convoluted with antecedent rainfall intensities to generate streamflow discharges. The method is applied to the Little River Watershed in South Georgia with encouraging results. Such models are useful in quantifying the response of ungaged watersheds and predicting streamflows in real time. In turn, such studies are instrumental in the design and operation of reservoirs.
