Integrated Land Use Change Analysis For Soil Erosion Study In Ulu Kinta Catchment
Ulu Kinta catchment has experienced rapid changes in land use and land cover from 1991 to 2004. These changes have resulted in increased upland erosion and higher concentrations of suspended sediment within the catchment. The goal of this research was to investigate the application of integrated...

description |
Ulu Kinta catchment has experienced rapid changes in land use and land cover
from 1991 to 2004. These changes have resulted in increased upland erosion and
higher concentrations of suspended sediment within the catchment. The goal of this
research was to investigate the application of integrated satellite remote sensing and
Geographic Information Systems (GIS) techniques to assess land cover changes
and the estimation of soil erosion in the water catchment. Inherent in this research
was the interpretation of multi-sensor data collected by several satellite systems,
evaluation of the quality of the resulting change information, application of remotely
sensing and other ancillary data as input in GIS-based RUSLE model to analyse soil
erosion process induced by different land cover changes. Change detection was
performed using post-classification comparison method which produced acceptable
results, overall accuracy 61.4 % and kappa = 56 %. The study revealed that while the
estimated mean annual soil loss rate was approximately 16.2 tons/ha/yr and 52
tons/ha/yr for 1991 and 2004 respectively, soil loss rate as high as 172.0 tons/hr/yr
were found on sloping lands from Ulu Kinta catchment. A good correlation of r' =
0.9169 was obtained between modeled annual average soil loss estimation and
annual average sediment loads obtained at site. Results of the study indicate that land
use changes in the study area have produced environmental problems such as water
pollution and soil erosion. In this research, a comprehensive methodology was
developed to collect representative data quickly and simply, showing that in a GIS
environment the RUSLE model can be applied to determine field-scale soil loss
quantitatively and spatially, to predict erosion hazard over given watershed. The study
indicates that the RUSLE-GIS model is useful tool for resource management and soil
conservation planning. |
