dc.description.abstract |
Demand for water in Hambantota district is increasing rapidly due to
agricultural activities, massive on-going development projects, industrialization and
consequent population growth. Implementation of a proper water management
system is essential in facing predicted water stress conditions where groundwater
resources can play an important role. Delineation of groundwater potential zones,
recharge zones and groundwater quality assessment can be identified as the three
main segments of groundwater management. Geospatial technologies can be
successfully utilized in such endeavours due to the cost and time effectiveness.
Ambalantota Divisional Secretariat was selected as the study area in this research
work. Rainfall, contour, geology, geomorphology, soil and drainage network data
along with Landsat 7 ETM+ image were utilized to develop relevant thematic layers
in delineating groundwater potential zones and recharging sites through a weighted
overlay model on a GIS platform.
Field studies were carried out to collect samples for water quality analysis and to
verify the results. Groundwater quality map of the area was generated based on the
results of laboratory analysis, depicting suitability level for drinking.
The results indicate that Ambalantota DS has significant groundwater potential and
recharge potential, hence can be effectively utilized as a hub for a water
management system in Hambantota district. |
