Shallow Aquifers

The study looks at chemical characteristics of groundwater in Jammu and Kathua on the basis of thirty water samples collected from open wells during July and December, 1997. The water quality has been evaluated for irrigation and drinking purposes. The suitability of water for drinking purposes has been compared with the standard norms i.e., BIS, 1983 and WHO, 1984.

The report summarizes aspects of the theory of anisotropic flow in porous media and reviews the methodology for computing hydraulic potentials in an unconfined aquifer system. An algorithm has been devised by applying appropriate transformation techniques for anisotropic domain.

Numerical experiments have been performed using the algorithm to compute hydraulic potentials in certain hypothetical anisotropic aquifer systems. A number of cases have been studied with different coefficients of anisotropy for the aquifer as well as the angle inclination of the bedding planes of the soil strata. The simulated hydraulic potentials in the anisotropic domain are established as equipotential lines in vertical sections.

Mazhapolima is a community based well recharge programme, initiated by the Thrissur District Administration in collaboration with the Panchayat Raj Institutions in the District, and implemented by networking NGOs/CBOs, households, departments and agencies, research institutions, private sector and all other key stakeholders, who are either a water user or a water provider/planner.

Diversity of approaches and implementation arrangements according to location specific needs centered on sustainable outcome and service levels are the underlying tenets of the programme. The programme envisages recharging of about 4.5 lakh open wells in the district to ensure sustainable access to water.

Use of rain water to recharge quickly the deep under ground water pockets

Present problem:

1. Due to urbanization, many a under ground water recharge/enrichment points have be closed/covered/blocked. So, % of water reaching the underground water pockets is reduced to a very great extent.
2. Bore wells are dug at a very large number to satisfy the increasing demand for water. Therefore, level of underground water table is going down alarmingly.
3. As  many the opportunities for the rain water to reach the underground level is blocked almost at all places, even with a little bit of rain, the water will run on the roads & cause artificial flood or water blocking at different points on roads or low laying areas of the Cities. Such floods are causing a lot of traffic jams/road mishaps.Rain water on the road is also damaging the durability of the TAR roads.

By using dried open wells, we can enrich the Underground water quickly.

In the good old days, open wells used to help the common man in fetching water for all purposes and specially the drinking water. Invasion of pump-sets and specially the deep bore wells have pulled the underground water indiscriminately. Therefore, the water table level of the underground water is continuously going down at a very alarming rate. This fall in the underground water table level has made many a very big and useful water wells dry up. Now they are not in use as people do depend on alternative source of water like bore well water or the tap water drawn from far off river water.

The State sector scheme on artificial recharge to groundwater through dug-wells is under implementation over the first three years of the (current) XI Plan Period (2007-12), in 1180 over-exploited, critical and semi-critical blocks/ talukas/ mandals in seven states of the hard-rock peninsular region of India, namely Andhra Pradesh, Maharashtra, Karnataka, Rajasthan, Tamil Nadu, Gujarat and Madhya Pradesh. The target beneficiary of the scheme are farmers who have privately owned wells, in their agricultural land.

The Vand Women of Kachchh: Guest post by Keya Acharya

She gazes unflinchingly with direct eyes into the camera with a feminine mystique and physique that could, be gracing the front cover of a beauty magazine. Her red, mirror-worked blouse, in the traditional Kachchhi style worn by tribal women, is strapped at the back in stringed bows, greatly practical in the dry, wilting heat of that arid expanse of land in hinterland Gujarat called Kachchh. Her skirt is a colourful hue of printed green, and her ‘dupatta’ is a blazing red piece of cloth swept forward from her waist, partially covering her back, brought over her head and tucked back demurely into her waist again. Her name is Ammi.

The Best Part of the Story: Guest post by Keya Acharya

The landscape is barren in parts with just high heat and sun-bleached sand, the hallmarks of wastelands; in other parts there is some semblance of agriculture, with jowar, bajra and sometimes castor growing in small patches of mild green, without the lushness that good watering provides.

And in the middle of this landscape there appears, like an oasis without the accompanying palms, the ‘Tinnavahd talab’, a drinking water pond constructed by the community at Rabarkar vand, near Lakhagarh village in Rapar taluk of Kutch district. Inside the pond there is a dugwell, constructed on the pond bed.

Mazhapolima was a participatory well recharge programme initiated by the Thrissur district, under which domestic water sources were recharged with rainwater harvested (usually) from roof tops.
