| Abstract | Detail thematic maps of rain erosivity, soil erodibility, and
slope were prepared from the rainfall data, soil analysis, and
contour information respectively. SPOT HRV data of 3 bands (26-08-
1986) was used f .or the Unsupervised Classification and subsequently
for the Supervised Classification in identifying seven basic land
use/ land cover classes. All the derived information were combined
together using GIS facilities available in ERDAS in developing an
erosion ยท hazard map for Hanguranketa, Sri Lanka. Eroded areas 1 :
identified as barren lands was spatially delineated with the same
3 band combination of SPOT HRV data. Further, land management
practices and the field erosion status at Hanguranketa were
investigated through an extensive farmer survey and field
observations. Eighteen sub watersheds within the study area were
also delineated and the erosion status at sub watershed level was
assessed in comparison with the eroded area identification map.
Subsequently, priority sub watersheds where implementation of
intensive conservation methodology is urgently required, were
recognized. Finally, all the derived and available data was
integrated together in developing conservation strategies and
planning for the sustainable utilization of the land resource at
Hanguranketa, Sri Lanka. |
