It solves the conservation of mass and 3D momentum equations and includes transport equations for temperature and salinity. Here we present a basic configuration of ROMS in the framework of the Web Modeling Tool (WMT), it is designed for inexperienced modelers to look at a river plume affecting the coastal ocean and sediment transport.

We set up a basic numerical experiment with inputs considered representative for a medium-sized river draining into the coastal ocean. The incoming river carries freshwater and suspended sediment into the salty ocean water. The river discharge is kept constant over the duration of the simulation at 1500 m3/sec. The model domain is 102 by 142 gridcells, gridcells are dx=500m and dy= 750m, so you are looking for this experiment ROMS has 20 vertical layers in the water column, and stores 10 layers in the ocean bed. Initial layer is 20 cm.
