Research outputs behind the practice
Engineering judgement is only as good as the evidence behind it. Our principals have spent 3 decades generating that evidence — much of it specific to equatorial catchments, tropical rainfall and Sarawak's own soils and rivers.
Research themes
- Probabilistic exposure modelling and environmental health risk assessment
- Hydraulic characteristics and discharge estimation for equatorial natural rivers
- Development of an Equatorial Soil Loss Equation (EQSLE) and RUSLE sensitivity analysis
- Rainfall intensity and raindrop size distribution under natural precipitation
- Integrated catchment management and water quality in Sarawak river basins
- Oil–water–solid phase separation and micro-scale wastewater treatment
- Biomass-to-heat and biomass-to-fuel gas energy conversion
- Dam break analysis and reservoir risk assessment
