OPTIMAL MONITORING NETWORK DESIGN IN
MAHESHWARAM WATERSHED FOR WATER LEVEL
Optimal water level monitoring network design is an important step for
better analyzing the aquifer behaviour by using the geostatistical method in
an unbiased way and to monitor the optimal network without loosing the
scientific benefits. Water level data was used in optimizing the monitoring
network of observation wells. A number of bore-wells (56) based on
geomorphology, land use and other variations were selected to have a first
hand network for measurement of water levels. The existing network consisted
of 56 bore-wells (Fig. 1) out of which 25 (IFP) were specially drilled for
monitoring the water levels and 31 (IFW) were selected from the existing
irrigation wells. The analysis of the variance of the estimation error obtained
using kriging technique on a suitably finer grid in the entire area has been
the basis to discard some of the private irrigation wells. The wells were
discarded in such a way that the variance of the estimation error does not
