Water Management

This presentation by ACWADAM on processes that shape the earth attempts to understand the irregularities of the surface of earth so as to consider the movement of groundwater. The earth’s surface is dotted with what is commonly perceived as high grounds or ‘hills’ and the low grounds or ‘valleys’. Hills and valleys result from movements in the earth and the long term processes of breaking-down the earth surface at some places and building it up at others, also called as diastrophism.  

The Eleventh Plan (2007-08 to 2011-12) sought to build on the gains achieved in the Tenth Plan and shift the economy to a path of faster and more inclusive growth. The Mid Term Appraisal (MTA) report for the Eleventh Five Year Plan 2007-2012 by the Planning Commission reviews the experience in the first three years of the Plan and seeks to identify areas where corrective steps may be needed.

This presentation by ACWADAM deals with integrated data management using Geographic Information Systems. A Geographic Information System (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information.

This presentation by ACWADAM deals with the subject of groundwater balance. It begins by describing the skeleton for the water balance equation viz., ground surface, soil, aquifer and bed rock. It describes the processes subsequent to rainfall such as interception, initial detention, depression storage, infiltration, runoff, streamflow, soil moisture retention and recharge.

The watershed water balance equation is explained in terms of input (rainfall and water transfers) and output (runoff, evapotranspiration and infiltration). It notes that the input to a generalized water balance is rainfall whereas the input to a groundwater balance is infiltration. The difference between infiltration & recharge, natural & artificial recharge and interflow & discharge are explained thereafter. The water balance for an aquifer may vary, depending upon the nature of groundwater system –

• Watershed with a deep aquifer
• Watershed has both shallow and deep aquifers
• Watershed has only shallow aquifer

Papers may address one or more of the following areas:

Situation analysis

• Studies assessing current and future water situation in India
• Water – climate change nexus and implications for the future

This presentation by ACWADAM deals with the conceptual framework of groundwater management.

This presentation by ACWADAM deals with the issue of groundwater management under the climate change scenario in India. Climate change is a change in the statistical distribution of weather over periods of time that range from decades to millions of years. The causes are -variations in solar radiations, plate tectonics, volcanism and change in earths orbit & axis.

This presentation on aquifer properties by ACWADAM deals with the storage and transmission properties of aquifers. The two functions of an aquifer, accumulation of water (storage) and flow of water (transmission) are discussed. The permeability or hydraulic conductivity of the aquifer which allows water to flow towards the well is described.
