Algorithm for Transient Sediment Deposition and Resuspension in a One-Dimensional Zone Between an Outfall and a Receiving Water

Abstract

<p>A mathematical model to predict the bed sediment and suspended sediment load as a function of time and distance along a one-dimensional quasi-steady receiving area is described. The model called TOTSED, uses the modified. Einstein approach for bed load calculations and the Einstein approach for suspended load calculations. The plug flow reactor is used for the inflow load (sediment pollutograph) calculations.</p> <p>The model was verified and calibrated using data obtained from a sampling program carried out in Chedoke Creek outfall channel in Coote's Paradise in Hamilton during summer 1980. Similar computations were carried out using the HEC-6 program. TOTSED predictions compare favourably with both HEC-6 and the observed data. TOTSED has been modified to be a new block of the SWWM program.</p>
