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.

Question For Delft3D-Flow

Youngling Posts: 2 Join Date: 1/7/15 Recent Posts
Hello, Guys~

My name is Wonhyun Lee, now I am interested in Cyclone model, but I have a big question for that.

In particular, for the evaporation and precipitation rate.

well, normally, Delft3D-Flow provides the XXX.eva (additional parameter : Fileva ;#XXX.eva#) files to apply it.


I would like to apply the spatial-temporal varying evaporation and precipitation rates into the model.
For example, if the cyclone is moving and landfalling to some area,
normally lots of rainfalls is accompanied with a hurricane.

So, could you please let me know, 'spatial-temporal varying evaporation & precipitation rates are available for Flow model?
any tips for input files (evaporation and precipitation rates)
or is there any option that evaporation & precipitation rates are included with a hurricane?

Have a great day.
