Estimation Of SIMHYD Parameter Values For Application In Ungauged Catchments
Rainfall-runoff models are used for various applications, ranging from the estimation of catchment water yield to the estimation of land use and climate change impacts on runoff characteristics. Most rainfall-runoff models can be calibrated successfully to reproduce the recorded runoff, however it is difficult to determine appropriate parameter values to use for modelling runoff in an ungauged ...
متن کاملEnsemble predictions of runoff in ungauged catchments
[1] A new approach to regionalization of conceptual rainfall-runoff models is presented on the basis of ensemble modeling and model averaging. It is argued that in principle, this approach represents an improvement on the established procedure of regressing parameter values against numeric catchment descriptors. Using daily data from 127 catchments in the United Kingdom, alternative schemes for...
متن کاملEstimation of Runoff Peak Flow by El-Hames Empirical Method for Ungauged Catchments: A Case Study Iranshahr
In this paper, the El-Hames empirical method was used to determine the peak runoff flow in Iranshahr catchment. The El-Hames method is based on morphological parameters and SCS Curve Number of the studied area. The implementing was processed by collecting the required data including soil type and vegetation cover, land use maps, digital elevation model and satellite images from the associated i...
متن کاملCalibration of hydrological model parameters for ungauged catchments
The parameters of hydrological models for catchments with few or no discharge records can be estimated using regional information. One can assume that catchments with similar characteristics show a similar hydrological behaviour and thus can be modeled using similar model parameters. Therefore a regionalisation of the hydrological model parameters on the basis of catchment characteristics is pl...
متن کاملEstimation of Flow Characteristics of Ungauged Catchments Case Study in Zimbabwe
University – with references and summaries in English and Dutch. i ACKNOWLEDGEMENTS I have received tremendous assistance and encouragement from several people during my PhD studies in both the Netherlands and Zimbabwe. Firstly, I would like to express my gratitude to Prof. dr. A.M.J. Meijerink who accepted the challenge of supervising a student who was going to spend most of the time away from...
