Modelling Rivers

River

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.

Constant depth and variable water level

Constant depth and variable water level

Hello,

I have a little problem running a simulation. The water level at the boudaries is rapidly growing while I want to keep it more or less constant.
Here are pictures of the depth, and then the water level at the first step of the simulation and about the middle of the simulation.

The depth is constant during the simulation.
How can I make water level also constant ?

Hi Remi
Could you indicate what kind of boundary conditions you are using. Please check as well my reply to the Flooding question.

Hi,

Actually, thanks to your reply to the Flooding question, I tried several things and managed to solve my problem.
Thank you very much !
