Southwest Pass Outlet Study

The Southwest Pass Outlets Study will provide flow measurement budgets between four outlets and Southwest Pass by measuring flow in Southwest Pass upstream and downstream of each pass and in the passes.  Flow measurements should be taken in a manner such that the existence of the piling dikes does not influence the flow measurement. The measurement may be taken at the dike cross section if this resolves the issue. 

Each flow measurement should be the resulting average of at least two transects. Three measurement sets will be provided at each outlet with the following tide conditions: one high tide condition, one low tide condition, and one intermediate tide condition.
