(mentor) Klaassen, G.J. (mentor) Faculty Civil Engineering and Geosciences Department Hydraulic Engineering Date 1989-06-01 Abstract Due to the relatively high computational costs related to the use of 2D models the purpose of this study was to develop a one-dimensional mathematical model that can give a fair estimation of the near-bank deformation and the bedtopography in meandering rivers. The bedtopography is characterized by a point bar-pool configuration that can also be reproduced by the MEANDER model that is presented here. The basic flow and sediment equations are elaborated into two systems of ordinary differential equations using an asymptotic series of trigoniometric functions that describes the transverse bed profile. Each system represents the odd and even terms of this series. The unknown parameters are the amplitudes at the banks of each term. These amplitudes are solved numerically in longitudinal direction and time. The model is applied on the Mekong river at the border of Thailand and Laos, between Vientiane and Nong Khai. Due to a lack of sufficient data the model is not yet tested thoroughly.
