Modelling Rivers


Rivers are natural water courses. They have vital contributions to the social and economical welfare of societies living along their course. They provide continuous, usually dependable, flow and supply of water. Accordingly, centralised civilisation began emerging independently along number of river valleys; e.g. the Nile, Tigris and Euphrates, the Indus and the Yellow Rivers. Since then, mankind has been in continuous struggle to understand and live in harmony with this gift/force of nature. Modelling rivers is the modern way to understand their behaviour and is an essential tool to tackle several river problems.

River and dam model

Hello everyone,

I am working on my thesis to set a river and reservoir model together. The reservoir was created to produce hydroelectric energy. Between river upstream and the dam there are approximately 40 km. The model lets analyze river's morphological process and dam’s sedimentation. Upstream the river has a water depth around 2 m and the dam reservoir depth is 40 m. So, I get my first question: Should I use more than one layer whether I only need to model flow and sediment process?

Besides, I set downstream boundary just in the dam, it means, I don’t have grid in the downstream dam. I have daily time-series with discharges from gates and spillway and water level. Upstream in the river there are daily time-series of discharges. Could anyone suggest how set boundary condition in the reservoir?

I attached an image to understand it better.

Thank you in advance.
