Description of Study Area

The study area, having an area of 48.78 acres, is primarily a developed urban land that has a coarse loamy soil type. With the exception of the depressions located in the parkland area, no major changes in topography are found in the study area due to the development. This implies that all the streets are, in general, followed the natural slope. Figure 2.1 represents the schemata of the combined sewer system modeled in this tutorial, which includes the combined sewer pipes (in green), the combined sewer channel (in red), the natural channels (in blue), the interceptors (in brown), the storm water conveyance pipe (in violet), the flow regulators (weir), and the pump station. The marked areas are shown in large scale in the insets of the map. Network summary information has been listed in following Table 2.2
