Geology of Eastern Ghats in Andhra Pradesh
GEOLOGY OF EASTERN GHATS IN ANDHRA PRADESH BY A. SRIRAaMADAS (Geology Departrael;t, Andhra UMversity, Waltair) Received October 2, 1967 (Communicated by Prof. C. S. Pi¢lmmuthu,t.A.sc.) ABSTRACT The lithology, structure, metamorphism and stratigraphy of the granite gneisses, charnoekite series, khondalite series and .granites occur- ring in the Eastern Ghats of Andhra Pradesh are described. The granite gneisses consist of the garnetiferous granite gneiss, the grey granite gneiss and porphyritic granite gneiss. The charnockite series consists of granite, diorite, gabbro, norite, amphibolite and pyroxenite. The khondalite series comprises gneisses, schists, quattzites, and granulites, metamorphosed from argillaceous, arenaceous and calcareous sediments. The granites include the pink granites and pegmatites. The formations are highly folded with thrusts and strike slip faults. The granite gneisses, charnockite series and khondalite series are metamorphosed to the gra. nulite facies, with a few members in the amphibolite facies and occasional members in the eclogite facies. Some granite gneisses are the oldest rocks present, and others contempolaneous with charnockite selies, which are themselves older than or contemporaneous with the khondalite series. The pink granites and pegmatites are the youngest rocks of the region. LOCATION TttE Eastern Ghats in Andhra Pradesh are situated between Latitudes 16° and 19 °, and Longitudes 80 ° and 85 ° , and stretch for about 350 miles from Srikakulam District in the north, through Visakhapatnam, Godavari and Krishna Districts, to Guntur District in the south. They include Kurupam, Madugula, Anantagiri, Gudem, Chodavaram, Papikonda, Kondapalli and Kondavidu hill ranges. GEOLOGICAL FORMATIONS Fermor ~1936) included the Eastern Ghsts in the garnetiferous type (manganese ore) marble provine belonging to the charnockite region. -

Version 2.0 Krishna Basin Preface Optimal management of water resources is the necessity of time in the wake of development and growing need of population of India. The National Water Policy of India (2002) recognizes that development and management of water resources need to be governed by national perspectives in order to develop and conserve the scarce water resources in an integrated and environmentally sound basis. The policy emphasizes the need for effective management of water resources by intensifying research efforts in use of remote sensing technology and developing an information system. In this reference a Memorandum of Understanding (MoU) was signed on December 3, 2008 between the Central Water Commission (CWC) and National Remote Sensing Centre (NRSC), Indian Space Research Organisation (ISRO) to execute the project “Generation of Database and Implementation of Web enabled Water resources Information System in the Country” short named as India-WRIS WebGIS. India-WRIS WebGIS has been developed and is in public domain since December 2010 (www.india- wris.nrsc.gov.in). It provides a ‘Single Window solution’ for all water resources data and information in a standardized national GIS framework and allow users to search, access, visualize, understand and analyze comprehensive and contextual water resources data and information for planning, development and Integrated Water Resources Management (IWRM). Basin is recognized as the ideal and practical unit of water resources management because it allows the holistic understanding of upstream-downstream hydrological interactions and solutions for management for all competing sectors of water demand. The practice of basin planning has developed due to the changing demands on river systems and the changing conditions of rivers by human interventions. -

Inter State Agreements
ORISSA STATE WATER PLAN 2 0 0 4 INTER STATE AGGREMENTS Orissa State Water Plan 9 INTER STATE AGREEMENTS Orissa State has inter state agreements with neighboring states of West Bengal, Jharkhand ( formerly Bihar),Chattisgarh (Formerly Madhya Pradesh) and Andhra Pradesh on Planning & Execution of Irrigation Projects. The Basin wise details of such Projects are briefly discussed below:- (i) Mahanadi Basin: Hirakud Dam Project: Hirakud Dam was completed in the year 1957 by Government of India and there was no bipartite agreement between Government of Orissa and Government of M.P. at that point of time. However the issues concerning the interest of both the states are discussed in various meetings:- Minutes of the meeting of Madhya Pradesh and ORISSA officers of Irrigation & Electricity Departments held at Pachmarhi on 15.6.73. IBB DIVERSION SCHEME: 3. Secretary, Irrigation & Power, Orissa pointed out that Madhya Pradesh is constructing a diversion weir on Ib river. This river is a source of water supply to the Orient Paper Mill at Brajrajnagar as well as to Sundergarh, a District town in Orissa State. Government of Orissa apprehends that the summer flows in Ib river will get reduced at the above two places due to diversion in Madhya Pradesh. Madhya Pradesh Officers explained that this work was taken up as a scarcity work in 1966- 77 and it is tapping a catchment of 174 Sq. miles only in Madhya Pradesh. There is no live storage and Orissa should have no apprehensions as regards the availability of flows at the aforesaid two places. It was decided that the flow data as maintained by Madhya Pradesh at the Ib weir site and by Orissa at Brajrajnagar and Sundergarh should be exchanged and studied. -
