Dear one and all

You may be well aware that rising of ground water table in any location is
attributed from the canal water supply, recharge of rain and water flowing down
the aquifer through internal flow and so to say, percolation and sideway
seepage.

cssri, karnal is the only institute so far to tackle ground water table,
waterlogging and salinity related problems. its regional station, at bharuch may
also be contacted through  the director so that its team, after authorative
approval may visit the spots and put in to its throughs and so the aftermath
approaches.

i think, being an agril engr and posted at bharuch, which has a mandate to work
in western part, particularly rajasthan may take initiative.

may be you can talk to dr. s. k. gupta, project coordinator, ex head and dr s k
kamra head irrigation and draiange engineering division at cssri karnal

skgupta@...,
skkamra@...
ggrao54@... at bharuch station

i shall be keenly interested to read about it further.

Subject: [rhydrology] Rising groundwater levels in Jodhpur City, India
To: rhydrology@yahoogroups.com
Date: Saturday, August 1, 2009, 6:10 PM

Dear Friend,

Jodhpur, a major city of Western Rajasthan in India, has been experiencing the
problem of rising groundwater levels in many parts of the city for last 11
years, after commissioning of the Rajiv Gandhi Link Canal (RGLC) which brings
canal water to Jodhpur city and stores water in Kailana lake located west of
Jodhpur city. Basements of buildings are being flooded in many parts of the
city. There can be one or more of the following probable reasons for rising
groundwater levels in Jodhpur city.

(1) Seepage from Kailana lake due to presence of lineaments/joints in Rhyolite
rock.

(2) Presence of impervious sandstone basement at shallow depth below the porous
Rhyolite aquifer in the city area.

(3) Seepage from pipelines carrying lake water.

(4) Leakage of used household water from unlined drain system.

(5) Reduced groundwater extraction from existing borewells and handpumps after
commissioning of RLGC.

For the above case, what would be the appropriate methodology to find the actual
reasons for rising groundwater levels in Jodhpur city and appropriate short-term
and long-term management plans for maintaining the groundwater levels at a safe
level.

Regards
Kumar
