Try the reservoir
Change the inflow, the release and the rain over the dam's catchment, and see what the reservoir would do over the next 90 days, starting from today's figures.
The reservoir would rise by 0.1 million m³ a day
Over the next 90 days the reservoir reaches neither normal storage, a rule curve nor dead storage
In 90 days it would hold about 104 million m³ (94.9% of capacity)
- Actual storage
- Projected
- Normal storage
- Upper and lower rule curves
- Dead storage
Today's storage, plus the inflow and the rain that runs in, less the release, a day at a time; evaporation and seepage are left out. It is arithmetic on the figures you set, not a forecast.
