An existing drain in Development A as illustrated in Figure 1 has been experiencing flooding problem. As the hydraulic engineer, you are required to identify the source of problem, prepare a hydraulic solution to the problem in the identified area, which can include detailed design of the proposed drain and culvert. You may use the hydraulic design manual in Malaysia (MSMA) in your design work. The length of drain and calculated design discharge are as given in Table 1. You are also required to identify an area where a culvert can be constructed. Show the complete calculations and states the assumptions made in the design.
