It has long been realized that tributary urban development and channel improvement greatly affect the flow regime in a given watershed. A previous study used the Stanford Watershed Model to derive relationships expressing how the flood peaks in Sacramento, California, might be expected to vary with changing conditions of urbanization, channelization, and tributary drainage area. In order to observe the effects of climatic setting and geographical location on these relationships, the same type of analysis was applied to a drainage area near Louisville, Kentucky.

If reservoir storage is to be considered in a flood control program, it is necessary to know how the entire flood hydrograph, not just the peak, may be expected to vary with changing watershed conditions. Relationships expressing these effects were also developed by applying the Stanford Watershed Model to both watersheds.

The necessary data were then assembled so that the University of Kentucky Flood Control Planning Program could be applied to the area in Louisville to illustrate the optimum flood control program in a growing urban area in a humid climate.
