Introduction DHI Modeling Software Water Resources - MIKE 11, MIKE SHE, MIKE Basin Marine - LITPACK, MIKE 21, MIKE 3 Urban - MIKE Urban
Marine Data Model Presented a different kind of challenge. Multiple features Multiple depths Multiple Measuring devices Measuring multiple variables Example: Moored buoy with a CTD cable with multiple sensors at every 10 m. At each depth one sensor is measuring temperature and salinity and a second sensor is measuring current speed and direction
