Abstract:
For the assessment of water resources under changing environmental conditions, dynamic process-based hydrological models are required. For a semiarid area in northeastern Brazil, rainfall characteristics and lateral redistribution of runoff components are shown to have a considerable influence on runoff simulations. Uncertainties in related data and parameters, and their effects on the simulation results, vary between wet and dry climatic conditions
