"Resource Planning in the case of water has to be done for a hydrological unit such as a drainage basin as a whole or for a sub-basin"


Contents

Introduction

River basin is considered as the basic hydrological unit for planning and development of water resources. There are 12 major river basins with catchment area of 20000 km2 and above. The total catchment area of these rivers is 25.3 lakh km2. The major river basin is the Ganga-Brahmaputra-Meghna , which is the largest with catchment area of about 11.0 lakh km2 (more than 43% of the catchment area of all the major rivers in the country). The other major river basins with catchment area more than 1.0 lakh km2 are Indus, Mahanadi, Godavari and Krishna. There are 46 medium river basins with catchment area between 2000 and 20000 km2. The total catchment area of medium river basins is about 2.5 lakh km2. All major river basins and many medium river basins are inter-state in nature which cover about 81% of the geographical area of the country.

Classification of Basin

India WRIS

Using the SRTM DEM data of NASA, having a spatial resolution of 90 meters, the basin ans sub-basin boundaries for the Indian subcontinent have been delineated. As per this information, the country has been divided into 25 Major River Basins and 103 sub-basins.The names of the basins are given in the table:

The AISLUS organization of the departments of agriculture and co-operation has been engaged in conducting rapid reconnaissance surveys for prioritization of smaller Hydrologic units within catchment areas of river valley projects and flood prone rivers.it has developed a system for delineating and codifying the catchment areas into smaller Hydrologic units i.e. sub watersheds following the 4 stage delineation. through the methodology developed has been serving the requirement of prioritization , a need for national level framework of watersheds, was always felt by the user agencies. the present bulletin on watershed atlas of india is an endeavor in that direction wherein the entire country has been divided into:

Background

Our National Water Policy recommends that resource planning in the case of water has to be done for a hydrological unit such as a basin or sub-basin. This means that all developmental projects in a basin should be formulated within the framework of an overall plan for a basin/sub-basin. The National Water Policy further lays down that there should be an integrated and multidisciplinary approach to the planning, formulation, clearance and implementation of projects, including catchment and management, environmental and ecological aspects, rehabilitation of affected people and command area development. Such an integrated, multidisciplinary and basin-wise approach to river basin planning and management requires the establishment of an appropriate organization at the river basin level for ensuring optimum, all round and balanced development of the water resources of a river basin.
River basin organizations envisaged above said function as a planning, co-ordination and management organization for the basin. It will combine various disciplines related to water resources development, drawing expertise from these disciplines in order to achieve optimal and integrated development of the water resources of the basin. It shall be charged with the authority for storage apportionment, regulation and control at various points in the river basin, publishing statistics or other information relating to various aspects of the regulation and development of the inter-state rivers and undertaking investigations, surveys etc. as found necessary.
The Government, as early as 1956, had enacted the River Boards Act, recognizing the necessity of some organization for the control and regulation of interstate river basins. The Act authorizes the Union Government to establish River Boards, on a request received in this behalf from a State Government or otherwise, for advising the Government bodies interested in relation to such matters concerning the regulation or development of an interstate river or river valley or any specified part thereof and for performing such other functions as may be specified in the notification.
So far, no effective river basin authority or organization has been established in the country for the integrated and optimum development of the water resources of basins. However, over the years since independence, a number of basin organizations have been created for limited purposes such as speedy implementation of master plans for specific purposes. An overview of the existing organizations is given below:

Existing Organizations

  1. Damodar Valley Corporation
  2. Bhakra-Beas Management Board
  3. Tungabhadra Board
  4. Ganga Flood Control Commission
  5. Betwa River Board
  6. Bansagar Control Board
  7. Brahmaputra Board
  8. Narmada Control Authority
  9. Sardar Sarovar Construction Advisory Committee
  10. Upper Yamuna River Board

Damodar Valley Corporation

The establishment of Damodar Valley Corporation (DVC) by an Act of Parliament in 1948 marks the beginning of an authority with the responsibilities for designing and administering comprehensive programme of development of river basin. The DVCDamodar Valley Corporation was modeled on the lines of Tennessee Valley Authority (TVATennessee Valley Autority) of the United States. The principal objectives of the DVC as laid down in the DVC Act, 1948 are promotion and operation of schemes for irrigation, water supply and drainage, generation, transmission and distribution of electrical energy, flood control and navigation, promotion of afforestation, control of soil erosion, promotion of public health and the agricultural, industrial, economic and general well beings in the valley and its area of operation. The DVC is headed by a Chairman and has two full-time members. The Secretary and the Financial Adviser works directly under the Chairman. The DVC has under its authority four dams namely at Tilaiya, Konar, Maithon and Panchet. Irrigation system from Durgapur barrage is with West Bengal Government since 1964.

Similar functions with regard to the Beas Project were also subsequently entrusted to the Bhakra Management Board which was renamed as Bhakra-Beas Management Board. The Board is entrusted with the task of administration, maintenance and operation of the two reservoirs for irrigation and power generation and regulation of supply of water to the States of Punjab, Haryana and Rajasthan and UT of Chandigarh and Delhi. The Board comprises of a Chairman, with two full time members.

The Board is in-charge of the common portions of the Tungabhadra Project which comprises of Tungabhadra Dam and reservoirs, low level canal, high level canal and right bank power houses. The Krishna Water Disputes Tribunal has made specific provisions in the Award for the use of Tungabhadra Waters by the States of Karnataka and Andhra Pradesh. The responsibility for carrying out these specific provisions relating to the use of Tungabhadra waters has been entrusted to the Tungabhadra Board by the Tribunal. At present the Board consists of a Chairman appointed by the Government of India, a Finance Member also from Government of India and Members representing Andhra Pradesh and Karnataka, all working part time on the Tungabhadra Board.

Ganga Flood Control Commission

The Ganga Flood Control Commission was constituted in 1972 by the erstwhile Ministry of Irrigation and Power through a Government resolution. The Commission serves as the executive limb and secretariat of the Ganga Flood Control Board, which is a body headed by the Union Minister of Water Resources as Chairman and Chief Ministers or their representatives of the basin-states and Lt. Governor of Delhi or his representative as members. The Commission is responsible for preparing a comprehensive plan of flood control in the Ganga basin and drawing out a phased programme of implementation of works to proper standards besides examinations of various schemes from techno-economic angle, monitoring of important flood management schemes and providing other technical guidance to the basin-states. The GFCCC is headed by a chairman appointed by the Govt. of India who also acts as the Member-Secretary of the Ganga Flood Control Board, and is assisted by two full-time Members. The representatives of the concerned Central Ministries/Departments as well as the Chief Engineers of the basin-states are either part-time members or permanent invitees of the Commission. The Commission’s function is restricted to only flood control projects and has jurisdiction over the Ganga basin.

Betwa River Board

Betwa River Board was constituted by the Union Ministry of Water Resources under the Betwa River Board Act, 1976.
