In-Depth Information
temperature monitoring device-recording system. Sensor attached with log-
ger poured into bore wells and depths can be measures with its graduated
cable. The observations were taken at 1 m interval. When sensor interact
the water, EC meter record the electrical conductivity, temperature and
depth. Laboratory study shows that even a minute mixing was preciously
recorded.

4. Results and Discussions
EC log profiles with depth have been carried out in nine bore wells during
June 2001 (pre-monsoon) at Maseshwaram watershed, four bore wells in
Wailpally watershed during October 2003 (post-monsoon) and also four
bore wells in Sadras watershed in February 2004 (post-monsoon). The
locations are shown in Fig. 1. One typical EC log profilings in Wailpally
watershed is shown in Fig. 2, which indicating the location of fractured
zones.
