Rivers

The presentation from the ENVIS - CES (IISc) website, emphasises the important role that the tank system has played in the development of the city of Bangalore and highlights:

•  The principles behind the working of the tank system
• The process of evolution of the tank system with respect to the growth of the city
• The underlying planning principles that were used in the tank system
• The role and importance of water tanks as an asset to the city
• The relationship between the system of tanks and the city of Bangalore
• The usefulness of the tanks as an important source of drinking water and agriculture in lean periods

These two documents from the KSPCB website, provide monthly water quality status data, for the rivers Tungabhadra, Cauvery and Kabini, monitored between January to June 2007, at various points along the rivers.

The data recorded are Temperature, pH, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Faecal Coliform.

As per the Press Information Bureau's press release, the Union Cabinet has approved the proposal of the Ministry of Water Resources for enacting The Dam Safety Bill, on May 13 2010. The Bill is to be introduced in the Parliament.

The main objectives of the legislation are:-

• The new legislation will help the States in adopting uniform dam safety procedures which shall ensure safety of dams and safeguard benefits from such dams.

This brief article by Prof Jayanta Bandyopadhyay in the May 16-31 2010 issue of Business Economics magazine, highlights the recent plans of the central and state goverments of constructing a large number of dams on Himalayan rivers. Environmentalists continue to consistently argue against the construction of dams that are built without respect for ecological sciences and warn that this could lead to increase in disasters in the fragile Himalayan region.

This document by Jayanta Bandyopadhyay, highlights the importance of the Ganges-Brahmaputra-Meghna (GBM) basin as an important source of water for many of the countries in South Asia, and the crucial role of negotiations in the context of the impending water crisis threatening the basin with the phenomenon of climate change.

The document argues that traditional water engineering has been found to be highly reductionistic and ineffective in bringing about development in the GBM basin and the continuing poverty in the GBM basin can be linked to the absence of a holistic ecological perspective, use of an incomplete framework for economics and ignoring of long-run economic costs of the actions proposed.

Honorable Prime Minister Dr. Manmohan Singh,

We, the undersigned, are writing this letter to ensure that the farmers and tribals displaced by the Sardar Sarovar and Maheswar dams are satisfactorly resettled and rehabilitated and that there is full compliance with environmental safeguards, before any permission is given for further construction work on these dams.

We deeply appreciate the fact that the Central Government has recently ordered suspension of work on the Maheshwar dam since the oustees are not resettled and rehabilitated, as per the requirements of the environmental clearance dated 01.05.2001. While over 80% of the construction work of the Maheshwar dam has been completed a mere 5% of the 70,000 oustees have been rehabilitated.

The paper discuses climatological and fluctuation features of important parameters of the Hydrological Wet Season (HWS), viz. starting and ending dates, duration, seasonal rainfall/rainwater and surplus rainfall/rainwater potential individually for the eleven major and thirty six minor river basins, the West Coast Drainage System (WCDS) and the rest of the country. It is based on reliable monthly rainfall data from a well spread network of three hundred and sixteen rain gauge stations from 1813 upto 2006.

The paper observes that the average period of the HWS is in close conformity with the southwest Monsoonal Rainy Season (MRS) over the basins in the Core Monsoon Rainfall Regime (CMRR). In the Mixed Monsoon Rainfall Regime (MMRR) covering south peninsula, northeast and extreme north, the HWS is of longer duration compared to the MRS due to extra-monsoonal rainfall over there. The mean starting date of the HWS is May 30, ending October 11 and the duration is 135 days for the entire country.

The paper critically evaluates the Greater Bangalore Water and Sanitation Project (GWSAP), implemented by the Bangalore Water Supply and Sewerage Board (BWSSB). This project aims to extend piped water supply from the Cauvery to over two million residents in peri-urban Bangalore. This ambitious project has been viewed against the backdrop of the broader trends and debates around market-based reforms in the water sector in Karnataka.

Hindus have always believed that water from India's Ganges River has extraordinary powers. The Indian emperor Akbar called it the "water of immortality" and always traveled with a supply. The British East India Co. used only Ganges water on its ships during the three-month journey back to England, because it stayed "sweet and fresh."
Indians have always claimed it prevents diseases, but are the claims wives' tales or do they have scientific substance?

The paper reviews contentious issues related to water governance in the Narmada river basin like the riparian rights of States over apportionment of the use of the waters for large dam-centered canal irrigation and hydro-electric power development and the later disputes around the appropriateness of this model of development given the tremendous environmental and social costs associated with it.
