feet against the railroad near Milliken Avenue. Because the water spreads laterally, Milliken Avenue runs the risk of becoming flooded; however, the water only ponds to 0.6 feet along the street. A more in-depth study is needed to see if the water would remain in the gutter or flood Milliken Avenue.

By observing the arrival times of the flood plain in figure 31, it is seen that the flood plain changes very little on the west side of the landfill once it reaches the railroad (0.6 hours after the dam-break). But on the east side of the landfill it takes 2.0 hours to reach the railroad.

Application 6: Estuary Modeling

Figure 32 illustrates a hypothetical bay, which is schematized in figure 33. Stage hydrographs are available at seven stations as marked in figure 32 and are numbered 1 through 7 (counterclockwise). Stage values in this application are expressed by sinusoidal equations (see Table 1). Some DHM-predicted flow patterns in the estuary are shown in figures 34 to 36. The flow patterns appear reasonable by comparing the fluctuations of the water surface to the stage hydrographs. DHM computed flow patterns compare well to a similar study prepared by Lai (1977).
