โœฆ Synopsis

Abstract

Ephemeral channels in arid regions convey larger amounts of sediment than perennial channels in humid regions. Sediment graphs at the outlet of channels have been derived by the standard sediment rating curve technique and by a lumped model based on the instantaneous unit sediment graph (IUSG) concept. The IUSG gives estimates of sediment transport that are better than those derived with the sediment rating curve as it takes into account the availability of erodible material within the channel bed.

This paper deals with the coupling of a sediment modelling algorithm to an existing conceptual model of water and salt ยฏuxes (LASCAM). In the model, sediment generation is based on a modiยฎed version of the universal soil loss equation. The sediment transport processes of channel deposition and re-en
