Abstract: Urban drainage and flood control must compete for funding from the limited public purse. Other types of evaluation problems are: (1) The determination of the merit of individual projects; (2) the ranking of competing UDFC projects to determine priorities; (3) the determination of optimal investment timing; and (4) the determination of the incidence of costs and benefits on different population sectors so that project costs can be equitably apportioned. The UDFC systems may be distinguished into minor or major systems, both for implementation purposes and for evaluation studies and public benefits differ considerably between the two types of systems. In the case of the major flood control project, attention has been focused on the potential reduction in flood damages associated with such projects. All public programs, e.g., public safety, water supply library services, urban drainage and flood control, and others should be subjected to the type of analysis presented to identify precisely the benefits from expenditures of public funds and the recipients of the benefits.
