Bathymetry

You can start a simulation in two different ways:

·         as a Cold start

·         as a Hot start

For modelling two-dimensional flow in rural and urban areas you can apply the Multi-cell overland solver.

Additional information describing the area you are about to simulate, obtained from the header information of the bathymetry/hot file, is:

·         The geographical position of the grid origin (main area).
If you are on the southern hemisphere, you should use a negative value for the latitude.

·         The grid orientation is measured clockwise from true north to the y-axis of your grid.

·         The projection zone (e.g. UTM-32) should be specified.

·         True land value is the minimum value you have specified for land points when you prepared the bathymetry.

Note: It is not possible to use a bathymetry specified for a Geographical Coordinate System such as e.g. LONG/LAT.

An example with a step-by-step description of how to use the Bathymetry Edi­tor for creating a bathymetry data file is included with the installation. Please find this example in your installation folder under Examples\MIKEZero\BatE­dit.
