Design of Improved Stormwater Management System for the Federal University of Technology Akure

Abstract

Stormwater management is becoming a problem in the city of developing countries due to rapid industrialization and poor infrastructure. Proper drainage system conveys stormwater from the road to a suitable disposal area. However, many of them are without functioning drains. The paper presents a sustainable approach to stormwater management in the developed area ofthe FUTA. The entire catchment area was divided into subcatchments that form the designated units for data collection. The result of the field work on the pervious and impervious area of the entire catchment showed that over half (57.31%) of the entire drainage area are grass land and the paved road covered 10.96%. the unpaved road and built up area covered 10.29% and 9.76% respectively. Others areas are thick forest (7.66%) and rock area (4.02%). The design of stormwater collection systems were based on the principles of hydraulics as explained by manning. The drain size was based on maximum discharge from each subcatchment and the time of concentration is computed by kirpich's formula. if the design is implemented, common flash flood and siltation along roads in FUTA will be completely eliminated.
