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. 
On this discussion page you can post questions, research discussions or just share your experience about modelling coastal and/or estuarine systems with Delft3D FM.

Z coordinates in Particle tracking usging Z-model

Hi,I am running a particle tracking based on a Z-model hydrodynamics. I have issues with the vertical coordinates of my particles. In the results of my PART simulation, the value near the water surface would be something like -70 while the value at the bottom is 1.02 something (When I try with release in different layers, these values are the initial starting points of the particles at time step 1). My idea is that the Z coordinate be the depth under the water surface. I don't know how these Z values could be interpreted as the bathymetry is above 100 meters but at where I release the particles, the water depth is only around 40 meters. Thanks in advance.

The new implementations were validated by using the output of the Z-coordinate Massachusetts Institute of Technology these values are the initial starting points of the particles at time step 1, doesn't work.. myprepaidcenter
