Ensemble 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 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 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 کاملTools and Approaches for Evaluating Uncertainty in Streamflow Predictions in Ungauged UK Catchments
A main limitation of using conceptual models for predicting flow in ungauged catchments is the errors in identified relationships between calibrated conceptual parameters and known (or estimated) catchment descriptors. It is hypothesised here that these errors may be reduced if the modeller does not explicitly identify relationships, but applies all feasible models within a Bayesian averaging s...
