Abstract
Groundwater from underground rivers is one of
the potential raw water sources in th
e karst area. Research to exploit the
potential sources of water from underground rivers in karst areas
is very important. U
tilization of water resources should be b
ased on
technique, environmental and social conditions. The problems are
to find the groundwater river flows, to design a well installa
tion, to
determine the feasibility, and to manage the water use. Analysis
of the results of geological mapping, topography, geophysical
measurements, drilling, pipeline and electrical survey, and pumpi
ng tests produce the feasibility of the water utilization. Geo
electric
data indicates there is a satura
ted zone at a depth of about 70-90 m from the su
rface. Well construction
is implemented by usin
g a 83
m PVC (Polyvinyl Chloride) pipe and a 15 m screen length. Th
e groundwater level remains stable even though it has been pumped
with a maximum discharge of 5
liters/sec. Based on the elevation difference fro
m topographic mapping results, the number of boo
ster
pumps can be calculated.
Utilization of water from underground ri
vers can overcome the problem of water shortage in dry area.
Key words:
