Topological and canonical kriging for design flood prediction in ungauged catchments: an improvement over a traditional regional regression approach?
In the United States, estimation of flood frequency quantiles at ungauged locations has been largely based on regional regression techniques that relate measurable catchment descriptors to flood quantiles. More recently, spatial interpolation techniques of point data have been shown to be effective for predicting streamflow statistics (i.e., flood flows and low-flow indices) in ungauged catchme...
متن کاملDesign Flood Estimation in Ungauged Catchments: Quantile Regression Technique And Probabilistic Rational Method Compared
Estimation of design floods in ungauged catchments is frequently required in hydrological practice and is of great economic significance. The most commonly adopted methods for this task include the Probabilistic Rational Method, the U.S. Soil Conservation Service Method, the Index Flood Method and the U. S. Geological Survey Quantile Regression Technique. The Probabilistic Rational Method has b...
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 کاملRegional Analysis Low Flows in the Karkheh and Karoon Catchments
Analysis of low flow is one of the important considerations in any water resource project. Meanwhile, as a general idea it seems that flow control is more important than drought mitigation but it is necessary to pay more attention to drought problem in future projects. In this paper, available data for 28 selected watersheds were analyzed and then Flow Duration Curve was drew, and discharge of ...
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 ...
