Abstract

In this paper, development of a semi-two- dimensional mathematical model called SDARis introduced. The model is composed of two principal modules of hydraulics and sediment transport. The newly developed SDAR model has a number of capabilities including determination of sediment transport rate, aggradation - degradation calculation, longitinal profile and lateral cross-sectional variation simulation, and tracing armor iayer development phenomena. SDAR is a semJ- two dimensional (S-lD) model, in the sense that the lateral variation of velocity, shear stress, and rate of sediment transport are achieved by subdividing the channel course into several stream tubes carrying equal discharges. Sediment routing and BED VARIATION calculations are accomplished along each stream tube designated by virtual interfaces.
