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.

Hello, everyone, after using parallel computing flow module, I chose to cal

Hello, everyone, after using parallel computing flow module, I chose to calculate the core n = 24, because my computer is 24 cores. As a result, com files and hyd files are divided into 24 copies. Then I downloaded ddcouple and ran DDB files. As a result, only hyd files are merged, and the total size of the merged hyd files is 2.5 kb. My question is, why are files split after parallel computing? And why is the merged hyd file so small? Thank you for your advice.
