Evaluation of overland flow models using laboratory catchment data I. An apparatus for laboratory catchment studies
A laboratory catchment provides experimental control over hydrological variables which is notably absent in the monitoring of experimental and representative basins. In designing an apparatus for laboratory catchment studies, particular attention must be paid to the methods of simulating rainfall over, and of measuring discharge from, the artificial catchments. The former should reflect the imp...
متن کاملEvaluation of overland flow models using laboratory catchment data EL Parameter identification of physically based (kinematic wave) models
Abstract Using the Imperial College laboratory catchment facility data from 96 experiments on a slightly-roughened varnished strip catchment (1 m x 9.925 m) are used to investigate the performance of numerical models of overland flow based on the kinematic wave approximation. A simple four-parameter model incorporates the Darcy-Weisbach laminar flow and Manning turbulent flow friction relations...
متن کاملEvaluation of catchment models
Catchment models are by definition simplified representations of the real world system. This aggregation takes place in space and time and has several important consequences. First, there are no generally applicable rules to perform this aggregation, and the resulting model structure is usually a function of the modeller’s hydrological understanding. Secondly, the model parameters cannot be mea...
متن کاملOverland flow: interfacing models with measurements
Van Loon, E. E., 2001. Overland flow: interfacing models with measurements. PhD thesis, Wageningen University, The Netherlands. 185 pp, 75 figs, 39 tables, 5 appendices. This study presents new techniques to identify scale-dependent overland flow models and use these for ensemble-based predictions. The techniques are developed on the basis of overland flow, rain, discharge, soil, vegetation and...
متن کاملEvaluation and Comparison of Topographic Correction Models Is Applied on the Series Landsat Images Using Spectrometery Data
The effect of topography on the radiance record in satellite image, probably reduce the accuracy of algorithem impliementation on the images . Therefore, to reduce the effect of topography, various correction models based on interaction between light and object needs to be defined. This research introduces lombertin correction model (Cosine model) and non_lombertin correction model (mineart and...
