| Abstract | Soil erosion is a serious problem all over the globe especially in the developing countries including Thailand. The prediction and monitoring of soil erosion is an area of active research which needs additional attention. Unless soil erosion is significantly reduced in near future, agriculture production in Thailand will be adversely affected. This research deals with the ways and means of predicting and monitoring the soil erosion in Thailand using NOAA AVHRR satellite images and GIS. The NOAA images of 1986 and 1996 with Local Area Coverage of 1.1 km. have been used in this study. The other data sets used in this study are one Kilometer DEM and 1 :500,0000 scale soil map. The study has been carried out using a simple model which relates the phenomena of soil erosion to topography, soil and the vegetation. T'1e model has been applied in the nine river basins of the Thailand that are: Ping, Yorn, Salawin, Mekong, Sakae Krang, Tonie Sap, Peninsula East Coast, Wang and Klong river basins. These river basins have varied vegetal, topographic and geomorphic characteristics and are spread over the all regions of the country. The study has shown that it is possible to use the low resolution satellite data for monitoring of the soil erosion phenomena. The results are likely to be useful of the monitoring of the impacts of land development and land use change for the larger areas of variable terrain. The results can be useful for management purposes and can also be used for framing out national policies which may have appreciable affect on the land resources in the country. The result must be seen with in the constraints of the data sets used in the study and need to be carefully qualified in scientific applications. |
