Characteristic levels time series

The following characteristic levels in a Reservoir must always be specified:

·         Bottom level: the bottom of the Reservoir

·         Dead zone level: the minimum level from which water can be utilised (Top of dead storage). If the water level is below this zone water can only be lost due to evaporation or bottom infiltration.

·         Dam crest level: the highest water level in the Reservoir before spill occurs. note that Dam crest level is not used for Lakes.
