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 Flooding model

Hello all,

First of all ,my sincere apologies if this a silly question, i am trying to do a river flooding modelling using delft-3d , i am finding differences in water level when applying discharge as a open boundary method [Total discharge] and another method [discharge in a cell] under operations tab.

In both cases i am applying discharge as 500 m3/sec, and the results are obtained as follows boundary method- no flooding , very low water level , result is obatained as range in 10 x -16 m3/sec
2.under discharge tab - huge flooding , normal flooding , result is obtained as range 4 to 5 m

I don't know which method is correct , please guide me.....
