Another step on the difficult journey to regionalise a probability-based loss model

Abstract

There is an industry need for guidance on loss model parameters to inform their application in ungauged catchments for design flood loss estimation. However, to date there has been only a limited number of studies which seek to understand how loss model parameter values are related to catchment characteristics in order to provide such guidance. Additionally, due to data restrictions when modelling losses across entire catchments, commonly used loss models (such as initial loss – continuing loss (IL/CL)) are typically quite simplistic and have only a limited physical basis. For this study, the relationship between parameter values of the loss model SWMOD and outputs from the Australian Water ..
