Figure 3, Plan view of tidal-flat drainage and cross section of the drainage 

 region at the study area (Fig. 2). Crosshatched drainage region 

 (plan view) enclosed all of the tidal flat below elevation of +22 

 feet (MLLW datum) that slopes toward and intersects the 22-foot 

 cross-section channel (right) . Only the channel flow area A is 

 considered in the discharge-area computations.
