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.

file.eva error in reading the file of precipitation

Dear all,
I am modeling a wetland and need to add the precipitation file. As prescribed by the manual, I inserted four columns for time, precipitation, evaporation and rain temperature, separated by one blank (see the attached file). For evaporation, I inserted the value of -999.0, as I want DELFT to calculate it internally.
When running the simulation, I receive the message of error in reading the file. What am I doing wrong? Is it possible that maybe I am missing some flags in the "additional parameters" section? For now, the only related additional parameter is Maseva = #Y#

Thank you,
Stella
