This paper describes the use of Geographic Information System (GIS) and remote sensing for assessing the impact of land use changes to water turbidity in multiple watersheds. In this study, necessary data sets representing land uses, hydrology, weather, soils, elevation, and surface characteristics were integrated in a GIS in tabular, vector and grid formats. The land use maps that were derived from Landsat-5 TM imagery using a combination of different classification strategies gave an average accuracy of 95 %. Results from data analysis had shown that there exists a close relationship existed between the extent of open area and sedimentation loading rate. However, the sediment loading rates were found to be non-linear ranging from 1.47 to 2.13 tonnes per millimeter of rainfall for each kilometer-square increase of open areas, depending on their location of open areas with respect to factors such as availability of sediment, soil type, slope length, and slope steepness etc. 2011-09-14T09:10:48Z 2011-09-14T09:10:48Z 2008-03 Article The Journal of the Institution of Engineers, Malaysia, vol. 69(1), 2008, pages 13-18 0126-513X http://www.myiem.org.my/content/iem_journal_2008-179.aspx http://hdl.handle.net/123456789/13746 en The Institution of Engineers, Malaysia |
