Abstract

Land areas in the territorial waters will often be affected by sea-level flooding or commonly referred to as rob. This research was conducted to see the physical condition of the waters and to do a hydrodynamic model (2D) in the waters of the Tembesi Reservoir, Batam, Indonesia. This research was conducted using primary and secondary data to produce physical conditions of waters and hydrodynamic (2D) models. The results showed the depth of waters has a minimum value of depth of -1.05 meters and a maximum value of depth of -5.95 meters. The percentage of wind speed below 1 Knot is 3.23%, and the independent variable in the percentage of wind data processing is 1.61%, with the lowest wind speed in the range of 0.1-1 Knots. Water level models produced in conditions during the filling process before the water discharge from the outlet is 0.023 meters and relatively small currents range from 0.0012 cm/s. Elevation of the final water level to the final flow when the conditions during the filling process before the water is discharged, resulting in highest water elevation, compared to when the water condition in the reservoir has been discharged from the outlet into the sea.
