where
; ; and ST(zw) is storage capacity of the reservoir at water-surface elevation zw. |
Again, the average water-surface elevation of the two nodes is used to define the storage so that all the partial derivatives will be nonzero for equation 88 in the nonlinear solution for the unknowns. The lateral inflow, IM, is computed for level-pool reservoirs in the same manner as for branches. One or more outflow relations can be associated with a level-pool reservoir. These relations are, however, viewed as internal boundary conditions for the stream system simulated with FEQ and not as part of the reservoir. The level-pool reservoir equations describe only the storage of water in the reservoir.
