Development of Drainage Management System for Urban Areas with Stream Blockage Problems in Kok River Basin

Abstract

Development of the drainage management system for urban areas with stream blockage problems in the Kok river basin did by collecting information about the causes and issues of stream blockage in the river and roads that obstructed the stream with specific locations. The statistical hydrological data were determined the peak discharge including the Intensity-Duration-Frequency (IDF) curves for each of the districts in the Kok river basin and the regional flood frequency analysis. The concept designs concluded from the statistical hydrological analysis were used for solving the problems of stream blockage. The results showed 75 locations with stream blockage problems, 40% of natural causes and 60% of human causes. The data and results were collected into the drainage management system of the geographic information system.
