I am trying to simulate a lake that has an intake structure with 4 fixed withdrawal tiers at 4 lake elevations (5m apart), the deepest tier being at 7m above the lake floor. Each tier has six 42 inch butterfly valves arranged in a circle around the structure at equal distance from one another. Outflow is controlled by opening the valves selectively at desired elevation based on water quality preference and flow rate. Usually two of the tiers are operated simultaneously for water withdrawal and I only have total outflow rate at any given time and information which of the tiers and valves were open. The structure is located within the lake (about 50 m from the dam at the cell highlighted below (37, 4, 1:26)).
| 1 | 2 | 3 | 4 | 5 |
| 34 | 999 | -0.0843 | -14.4437 | -15.6525 | -19.1895 |
| 35 | 999 | 999 | -13.9834 | -17.7313 | -19.53 |
| 36 | 999 | 999 | -12.6246 | -21.583 | -20.3237 |
| 37 | 999 | 999 | -6.7805 | -22.7061 | -18.1163 |
| 38 | 999 | 999 | -4.3764 | -14.7697 | -14.4504 |
| 39 | 999 | 999 | -3.1046 | -9.609 | -13.2498 |
| 40 | 999 | 999 | -1.7594 | 999 | 999 |
Any suggestion to represent the structure and if possible an example BC and outflow file is greatly appreciated.
Thank you
