intro story Coast / Estuary

Coast / Estuary

Coastal systems are among the most dynamic physical systems on earth and are subject to a large variety of forces. The morphodynamic changes occurring to coastlines worldwide are of great interest and importance. These changes occur as a result of the erosion of sediments, its subsequent transport as bed load or suspended load, and eventual deposition. 
 
Estuaries are partly enclosed water bodies that have an open connection to the coast. Estuaries generally have one or more branching channels, intertidal mudflats and/or salt marshes. Intertidal areas are of high ecological importance and trap sediments (sands, silts, clays and organic matter).
Within the Delft3D modelling package a large variation of coastal and estuarine physical and chemical processes can be simulated. These include waves, tidal propagation, wind- or wave-induced water level setup, flow induced by salinity or temperature gradients, sand and mud transport, water quality and changing bathymetry (morphology). Delft3D can also be used operationally e.g. storm, surge and algal bloom forecasting.

River and dam model

Hello everyone,

I am working on my thesis to set a river and reservoir model together. The reservoir was created to produce hydroelectric energy. Between river upstream and the dam there are approximately 40 km. The model lets analyze river's morphological process and dam’s sedimentation. Upstream the river has a water depth around 2 m and the dam reservoir depth is 40 m. So, I get my first question: Should I use more than one layer whether I only need to model flow and sediment process?

Besides, I set downstream boundary just in the dam, it means, I don’t have grid in the downstream dam. I have daily time-series with discharges from gates and spillway and water level. Upstream in the river there are daily time-series of discharges. Could anyone suggest how set boundary condition in the reservoir?

I attached an image to understand it better.

Thank you in advance.

RE: River and dam model

Hi how are you? I am going to do something similar..how was it going?
