Abstract

Wildfire represents a potentially important threat to the security of water storage reservoirs situated in fire-prone forest catchments. From a water treatment perspective, managers are interested in exceedence probabilities for event suspended sediment loads rather than estimates of average annual loads. To address this, we aim to develop a stochastic model of wildfire and storm event probabilities that are linked to erosion response and suspended sediment loads entering reservoirs. In this paper we present a conceptual catchment-scale model framework that will form the basis for the development of this model. The study focuses on the two main forested water supply catchments that provide p..
