| dc.description.abstract | In the current context, waste dumping
could be identified as the foremost and rising
issue of Sri Lanka. Still, Sri Lanka has not followed
a proper waste recycling system and as a result,
the number of waste dumping sites was increased
in nearby suburbs and those locations
endangered to nature. Therefore, systematic
waste disposal and scientific location selection for
waste dumping is a national requirement.
This study investigated the waste dumping
problem in the third high populated area in
Colombo District, the Kesbewa Divisional
Secretariat Division. The suitability of waste
dumping of each land parcel was analyzed by
utilizing both raster-based and vector-based
approaches. Data were collected from Survey
Department of Sri Lanka and open-source
satellite data platforms. There are eight data
layers manipulated over the study such as
Building, Land use, Slope, Waterbody, Road,
Reservation, and Population. Further, an
investigation performed by using the
Geographical Information Sciences (GIS)
environment with the use of ArcGIS 10.5
software.
Finally, prepared the factor maps and identified
the suitability of land parcels for waste dumping.
Further, it has revealed that the existing
Karadiyana waste disposal site only has 38% of
suitability and not in suitable condition for waste
dumping. In addition, it directly connected to the
nearby Bolgoda river and emphasized as a major
warning to human and environment in future.
Consequently, in order to overcome that issue
identified three suitable locations for waste
dumping by the study in the Kesbewa area. | en_US |
