On the Sensitivity Analysis of Two Hydrologic Models

The development of new hydrological models and the enhancement of the existing models are needed for water management. For instance, increasing rainfall may accelerate water erosion in watersheds and raise the probability of flooding events in the urban areas. The impacts include environmental and social-economic conditions. The hydrologic models SEADS, a physical process based model and GURUH, an algebraic model based on statistical relationships, are being used to predict the hydrologic impacts of urbanization. These models need to be fully tested so that they can be used with confidence. The implementation of sensitivity analysis to these models is a useful tool in the calibration of the models, in their applications to different catchments, and to urban change in catchments, and also to investigate climate change over the catchments.
