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.

Delft3D is the state-of-the-art modelling framework for hydrodynamics, water quality, ecology, waves and morphology.
Here, in this space, we share knowledge & experiences, and discuss issues related to modelling of rivers.

error in computing the flow "d_hydro.exe" file

error in computing the flow "d_hydro.exe" file

I get the error below when I try to simulate my single domain flow. My "d_hydro.exe" file also doesn't work. Can someone explain me what could be causing such error or is such error caused because of my faulty "d_hydro.exe" file. I was able to run the models earlier but its only showing this error now. I tried running the previous flow simulation again and it still shows this error. So I am quite sure the error is not in my MDF file.
If anyone could give me an insight to it? would be great.
