abstract
The relation between rainfall and runoff is recognized as a dynamic problem. A statistically non-stationary, multi-dimensional rainfall generator is suggested. The model, capable of simulating historical storm exterior and interiors, assumes the validity of Taylor's hypothesis of turbulence within a storm interior. The suggested rainfall model is used together with a runoff model to study the accuracy of discharge prediction as a function of the rainfall sampling network. The runoff model used is a spatially distributed simulation based on a finite difference solution of the Kinematic wave equations.
