  abstract: This study was conducted on Gombak River and its watershed. Gombak River is situated mainly in the Gombak District in Selangor state and its lower zone is situated in the Malaysian Capital Kuala Lumpur. The motivation of this study is to ensure sustainable development, which is essentially has effects on surface water quality as 97 per cent of Malaysia's water supply is sourced from it; and to find a low-end alternative for water quality monitoring techniques, which are typically expensive and tedious. This will allow decision makers to plan safely to improve the quality of life while maintaining sustainable development. The main aim of this study was to identify a relationship between water quality and land use attributes through selecting the appropriate data generation methods and model building that can enable prediction and forecast of water quality index with high accuracy. This model coupled by the data generation method, could later be utilized as an important extension to major planning software in order to assist planners and decision makers to plan and decide safely for watersheds zones. The thesis examined the water quality of the river focusing on six water quality parameters, these were BOD, COD, AN, SS, pH, and DO in three monitoring stations as well as conducted laboratorial analysis in a fourth one. The data were then analyzed in order to understand its behavior and response to the activities within the watershed. The watershed of Gombak River was redefined using MapInfo from the recently updated coordinates of Gombak River, and the LU/LC data were extracted from the watershed for a discrete 20-years period. LU/LC data focused on five categories, these were build-up area, residential area, commercial area, industrial area and forest area. Methodologically, the thesis used a quantitative method of analysis such as ANN's Back propagation algorithm in order to examine the correlation and magnitude of relationship between the chosen water quality and LU…
  abstract: predicted and actual WQI. The findings also revealed that as the activities increased throughout the watershed, the values of WQI quality decreased accordingly. The accuracy of prediction of the proposed LA-WQI ranged from 94.3% to 99.3% between Actual DOE-WQI and LA-WQI for station 24 of Gombak River. The same approach was applied for station 18 at Gombak River. The results of predicted WQI obtained using LA-WQI, showed a continuous decrease of water quality. Prediction values of WQI for DOE, ANN and LA-WQI had an accuracy range of 97.9% to 99.5 %. In order to test the sensitivity of data generation method and the LA-WQI model, withheld data were used for the first time for validation. The results indicated high precision in the prediction and forecast of WQI. Generally, there is an appreciable effort to keep Malaysian rivers clean, however in order to achieve an accepted level of sustainability, all developmental schemes within a watershed vicinity should be conducted in accordance with a specific allocation of time and space which follows a certain model. This will help in producing more accurate forecasting of LU/LC sub-indices and hence WQI. Despite the high accuracy attained by the application of LA-WQI model on Gombak River; it has not yet been tested on other rivers due the limitation of the scope of this study. It is recommended that future studies should be able to further test the current model on a regional scale.
