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.

Why the water level keeps growing for ten years

I have done a hydrodynamic simulation for a lake for 10 years. The result is very strange : the water level keeps growing for ten years, from 10m to 160m. In general , the water level is 5m-20m. Can you help me solve the problems . thank you.

I would recommend looking closely at your boundary conditions for flow into and out of your lake. Perhaps if you provide some more information about your model (particularly the boundary conditions) people may be able to help you further.

There can be many reasons for the rising water level. For example, the water level in a lake changes depending on the amount of precipitation, the amount of evaporated water and the movement of tectonic plates, which lead to a change in the topography of the lake's bottom form. I think you should take advantage of the research paper writing service. Perhaps experts will be able to say something more accurately.
