MULTIPLE OBJECTIVE PLANNING OF LAND/WATER INTERFACE IN MEDIUM SIZE CITIES
Abstract
The primary objective in this research is to develop a methodology for solving the multi faceted urban drainage water management problem. The conflicting and incommensurable goals of land/water interface are analyzed. The best land use plan results in increased cost. Also the minimization of risk of pollution increases the cost. The urbanization factor, defined as the fractional volume gain in runoff as the result of urbanization, provides the linkage between the level and type of urbanization and stormwater planning. Another point of importance in stormwater planning is the random behaviour of the hydrologic variables. These observations emphasize that the urban water management problem is a multi objective optimization problem under uncertainty. Methods are established to account for the effects of urbanization. Using hypothesized probability distributions for independent hydrologic variables, new distributions are derived for overflows and receiving stream pollutant concentration by means of physical laws of hydrology. By putting together all these components the Multi Criteria Decision Making problem is formulated. A new algorithm is developed to solve the general MCDM problem. The methodology thus developed is used to solve a real life problem in West Lafayette, Indiana.
