Groundwater

This paper discusses the role of paleochannels, which are remnants of stream channels cut in older rocks/sediments and filled by younger overlying sediments, representing the distribution of valley systems, in meeting current and future water requirements.

This paper focuses on water management techniques used in two tanks constructed by the kings of the Vijaynagar Empire.

The first example taken, is that of the Anantraj Sagar built by the son of the minister of Harihar. The lake is still in use and there are inscriptions on stone near it which provide a thumb rule to constructing lakes. Construction of this lake began in 1369 and was completed in 2 years. The paper states that the length of the dam was 5000 dand, width was 8 dand and the height was 7 dand (One dand is about one metre).

This paper discusses the water management systems found in temples in coastal Konkan, based on a study of 5 temples in the district of Ratnagiri. The study area is a rocky and rugged country, with elevated plateau and intersecting creeks.

This method is a mathematical model, in which all the components in the water balance equation are known, and the only component which is considered unknown is the rainfall recharge.

The International ReSource Award is worth USD 150 000 in total and is granted to one or several projects selected by an international jury. Launched in 2002, the ReSource award is an internationally recognised prize for leadership in implementing the principles of sustainability in watershed management. It is conferred annually. The prize money is awarded exclusively for project implementation activities and not for building-up or strengthening the organizations that are submitting an application.

Eligibility to participate:

NGOs, private, scientific or public institutions and similar bodies are invited to participate in the tender for the International ReSource award for Sustainable Watershed Management. Projects comprising more than one institution (eg public-private

1. Meaning of Ground Water

• Water located beneath the ground surface.

 Groundwater is stored in and moves slowly through layers of soil, sand and rocks called aquifers. Aquifers typically consist of gravel, sand, sandstone, or fractured rock, like limestone.

We have taken up evaluation of 65 water sheds in Northern districts of Karnataka. These water sheds are spread across Bagalkot,Raichur, Koppala, Bellary and Davanagere districts.

This report by Aligarh Muslim University and Central Ground Water Board (CGWB) deals with groundwater flow modelling and aquifer vulnerability assessment in Yamuna–Krishni sub-basin of Muzaffarnagar district. For evaluation of the groundwater resources and for minimizing the error of estimation, the system has been evaluated through aquifer modelling where water balance is established using partial differential equation of groundwater flow and is solved with boundary and initial boundary conditions.

With tihs, they can improve water and sanitation service regulation and provision at international, national and local levels. Directed primarily at community groups, human rights NGOs, rights-based development practitioners and aid workers, this handbook aims to strengthen human rights-based advocacy by providing innovative and practical suggestions that activists and organisations can use in their work. It also acts as a resource guide for finding further information.

Water and sanitation are essential for living a healthy life with dignity. However, around a billion people across the world lack access to a safe and sufficient water supply to cover their basic needs. Over 2.5 billion people lack access to adequate sanitation and nearly 1.2 billion face the indignity of open defecation every day.

The Millennium Development Goal (MDG) target to halve the proportion of people without sustainable access to safe drinking water and basic sanitation by 2015 is seriously off track, with sanitation severely lagging behind. For example, estimates suggest that at current rates of progress, sub-Saharan Africa will miss the MDG water target by about 25 years, while the sanitation target may not be reached until well into the 22nd century.
