Predicting Suspended Sediment Loads At A Catchment Scale: A Comparison Between Models

Owing to financial and other constraints on natural resource management, comprehensive data on the physical processes that determine in-stream water quality are rare. Consequently, managers are looking to models as decision-making tools. One important application is to identify areas in greatest need of erosion management. There are many ways that suspended sediment loads can be assessed. The main constraints in the determination of loads are the data available and the scale at which this information can be applied. This study has used two models to estimate the suspended sediment load in a number of catchments in the mid-region of the Murrumbidgee River catchment. The loa
