Good Land-use practice or land and water resources management is the key remediate water quality in our rivers for sustainable water resources. This study is to determine the water quality status in the Limbang and Trusan basins comprised of Limbang River, Selidong River, Medamit River and Batang Trusan. Water parameters included pH, DO, BOD5, COD, TSS, Ammoniacal nitrogen, TFC and TCC were examined. Selidong River and Limbang River are comparatively more polluted than Sungai Medamit and Batang Trusan. Study showed that the mean annual soil loss, E, from bare Kapit soils on 30-degree slopes, were estimating to be 44,283 mt/ha/yr of contribution by logging, development and agricultural activities at the hilly areas. When the slopes of the areas are getting higher, the mean annual soil loss was calculated to get higher as well. Similarly, once the area been developed or cleared, the topsoil was stripped and the more erodable subsoil exposed; thus, the mean annual soil loss would increase dramatically.
