LINEAR AND NONLINEAR APPROACHES FOR SHORT-TERM RUNOFF ESTIMATIONS IN TIME-INVARIENT OPEN HYROLOGIC SYSTEMS

Open time-invariant linear and second-order nonlinear hydrologic systems with memory can be evaluated by the development of a method of expanding the kernels in sequences of unit-weighted orthonormal polynomials. The method is applied to the total rainfall--total discharge relationship. The watershed responses derived by the second-order nonlinear system demonstrated high sensitivity to input variations and predicted the runoff closely. The first-order system provided rather insensitive responses to input variations different from those encountered during the test period. /Author/
