Optimal construction cost for urban drainage systems: a case study in a drainage basin, western Hanoi

Abstract

    In a drainage system, construction cost of each item work and its drainage capacity has a close dependency. This paper presents methods for fomulating the objective function, the constraints and steps of obtaining solution. We appliedregressionmodels to determine construction costs of the headwork, chanel levels 1, 2, 3 and regulation ponds in order to find out the value of the objectivefunction for a study area being the urban drainage system located inwestern Hanoi.
