releasing it back to the bay to flow to the ocean during ebb flow. Pumps and control valves
associated with this procedure are located adjacent to the storage tanks.
A steady-state flow may also be created for representing ebbing or flooding currents. The piping
system is shown in Figure 1. Water is either collected (flood flow) or distributed (ebb flow)
