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.

Problem with layers in delft3D

Hello,
I'm trying to run a model with 7 layers in grid parameters, with sediment transport and tidal boundaries. The model can run, but when I watch the results, the velocity or water level are equal to zero after a few time step. I'm trying to set different forcing type of flow conditions (time series and astronomic), but the result doesn't change.
With only a one layer the model run without problem.
I think there are some parameters to add or change.
Thank you
