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.

Map File Time is Not Changing with Interval in GPP

Map File Time is Not Changing with Interval in GPP

Youngling Posts: 3 Join Date: 6/13/18 Recent Posts

So I ran a Flow simulation in d3d, my comm file is showing a correct interval of 10 mins as I had set, my time step is (0.05mins) but my map and history files have only the time at the start of the simulation throughout for all their files in GPP, anyone know why this is happening? However when I use quickplot to animate the map file works fine and shows a nice animation of sediment v time, so I know the results are fine then why is the GPP only showing one fixed time in the map file??
