| Abstract | A new city, Halong, was recently established in 1994 in a coastal Quangninh province, Vietnam. In order to meet the growing water demand of the new city, numerous researches are carried out. This study is the first attempt in application of remote sensing and Geographical Information Systems (GIS) for water resources development in the region. All surface water resources are mapped and a map of river system has been updated using digital image processing to support traditional visual analysis based on aerial photographs and Landsat5-TM images. Geological and geotectonic fault maps are also refined and together with other maps served as input to the updated database which is evaluated and analyzed in order to produce hydrogeological and environmental sensitive water resources zoning maps. The hydrological zoning map can be used as a guide map for further ground water exploration using more reliable traditional expensive geological and hydrogeological methods. Potential groundwater recharge zones in the region are determined. All surface water bodies and groundwater recharge zones are considered environmental sensitive and requested to be protected from pollution. Three potential groundwater sites are identified. They are located in the eastern part the city, northern part of the Dienvong river and in the Troi district of the province. However, the groundwater resource within the region is limited, and hence, should be reserved only for drinking purpose. An environmental zoning map is also made in order to be used as a guide map for development of water resources protection plan from possible pollution. Combination of remote sensing technology and GIS techniques is found to be a very effective tool for water resources development through this study. However, it should not be considered as a substitution but a tool for systematically gathering special data which are difficult to get by g1~ound methods and analyzing database that enable to reduce the volume of more expensive exploration works. |
