KINTA RIVER FLOOD MITIGATION AND CATCHMENT AREA REHABILITATION
HSS was engaged to undertake a planning study for the rehabilitation and flood protection of a 50,000ha former tin mining area in the Kinta Valley near Ipoh. Core work covered developing and applying a GIS-based mapping/analytical system using colour aerial photography, satellite imagery and GPS-based ground measurements. Fieldwork and analysis included collecting and analysing rainfall and flow data in Sg Kinta and preparing design flood flow and sediment transport estimates for use in hydraulic modelling. This led to the analysis of hydrological effects (including erosion yields) of alternative catchment rehabilitation systems, including agriculture, forestry, aquaculture and livestock. The work culminated in the formulation of flood mitigation plans, economic/financial analysis and the preparation of integrated development plans, including a pilot project.
