    FLOOD FORECASTING AND WARNING NETWORKPERFORMANCEAPPRMSAL 2008 GOVERNMENT OF INDIA CENTRAL WATER COMMISSION FLOOD FORECAST MONITORING DIRECTORATE NEW DELHI - 110066 Feb,2010 PREFACE Central Water Commission had made a small beginning in Flood Forecasting & Warning service in India in November 1958 with .one forecasting station at Delhi, the national capital, on the river Yamuna. Today, its network of Flood Forecasting and Warning Stations has gradually extended over the years and covers almost all the major inter-state flood prone river basins throughout the country. The network comprised of 175 Flood Forecasting Stations including 28 inflow forecast during the year 2008, in 9 major river basins and 71 sub basins of the country. It covered 15 states besides NCT Delhi and UT of Dadra & Nagar Haveli. The flood forecasting activities of the Commission are being performed every year from May to October through its 21 field divisions which issue flood forecasts and warnings to the civil authorities of the states as well as to other organizations of the central & state governments, as and when the river water level touches or is expected to touch the warning level at the flood forecasting stations. The flood season 2008 witnessed unprecedented flood events in recent history. Both the river Subarnarekha at Rajghat and river Ghaghra at Ayodhya had once again recorded in 2008 a fresh "unprecedented Flood", for the second consecutive year after experiencing a similar event in 2007. In addition, "unprecedented Flood" was recorded on river Puthimari at N.H.Road crossing, river Devi, a distributory of river Mahanadi at Alipingal and Gharghra at Elgin Bridge.

    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.

  • Slowly Down the Ganges March 6 – 19, 2018
    Slowly Down the Ganges March 6 – 19, 2018 OVERVIEW The name Ganges conjures notions of India’s exoticism and mystery. Considered a living goddess in the Hindu religion, the Ganges is also the daily lifeblood that provides food, water, and transportation to millions who live along its banks. While small boats have plied the Ganges for millennia, new technologies and improvements to the river’s navigation mean it is now also possible to travel the length of this extraordinary river in considerable comfort. We have exclusively chartered the RV Bengal Ganga for this very special voyage. Based on a traditional 19th century British design, our ship blends beautifully with the timeless landscape. Over eight leisurely days and 650 kilometres, we will experience the vibrant, complex tapestry of diverse architectural expressions, historical narratives, religious beliefs, and fascinating cultural traditions that thrive along the banks of the Ganges. Daily presentations by our expert study leaders will add to our understanding of the soul of Indian civilization. We begin our journey in colourful Varanasi for a first look at the Ganges at one of its holiest places. And then by ship we explore the ancient Bengali temples, splendid garden-tombs, and vestiges of India’s rich colonial past and experience the enduring rituals of daily life along ‘Mother Ganga’. Our river journey concludes in Kolkatta (formerly Calcutta) to view the poignant reminders of past glories of the Raj. Conclude your trip with an immersion into the lush tropical landscapes of Tamil Nadu to visit grand temples, testaments to the great cultural opulence left behind by vanished ancient dynasties and take in the French colonial vibe of Pondicherry.

  • The Conservation Action Plan the Ganges River Dolphin
    THE CONSERVATION ACTION PLAN FOR THE GANGES RIVER DOLPHIN 2010-2020 National Ganga River Basin Authority Ministry of Environment & Forests Government of India Prepared by R. K. Sinha, S. Behera and B. C. Choudhary 2 MINISTER’S FOREWORD I am pleased to introduce the Conservation Action Plan for the Ganges river dolphin (Platanista gangetica gangetica) in the Ganga river basin. The Gangetic Dolphin is one of the last three surviving river dolphin species and we have declared it India's National Aquatic Animal. Its conservation is crucial to the welfare of the Ganga river ecosystem. Just as the Tiger represents the health of the forest and the Snow Leopard represents the health of the mountainous regions, the presence of the Dolphin in a river system signals its good health and biodiversity. This Plan has several important features that will ensure the existence of healthy populations of the Gangetic dolphin in the Ganga river system. First, this action plan proposes a set of detailed surveys to assess the population of the dolphin and the threats it faces. Second, immediate actions for dolphin conservation, such as the creation of protected areas and the restoration of degraded ecosystems, are detailed. Third, community involvement and the mitigation of human-dolphin conflict are proposed as methods that will ensure the long-term survival of the dolphin in the rivers of India. This Action Plan will aid in their conservation and reduce the threats that the Ganges river dolphin faces today. Finally, I would like to thank Dr. R. K. Sinha , Dr. S. K. Behera and Dr.

    The Crafts and Textiles of Hyderabad and Telangana 11 Days/10 Nights Activities Overnight Day 1 Fly U.S. to Hyderabad. Upon arrival, you will be transferred to Hyderabad your hotel by private car. Day 2 The city of Hyderabad was constructed in 1591 by King Hyderabad Muhammad Quli Qutb Shah of the Qutb Shahi dynasty, which ruled this region of the Deccan plateau from 1507 to 1687. During this time, the Sultanate faced numerous incursions by the Mughals and the Hindu Marathas. In 1724, the Mughal governor of the Deccan arrived to govern the city. His official title was the Nizam- ul-Muluk, or Administrator of the Realm. After the death of Emperor Aurangzeb, he declared his independence and established the Asaf Jahi dynasty of Nizams. The Nizams of Hyderabad were known for their tremendous wealth, which came from precious gems mined in nearby Golconda (see Day 3), the area's natural resources, a vibrant pearl trade, agricultural taxes and friendly cooperation with the British. Much of the architecture still existing in Hyderabad thus dates from the reigns of the Qutb Shahi Sultans or the Nizams. European influences were introduced by the British in the 19th and 20th centuries. At the center of old Hyderabad sits the Charminar, or "four towers," which dates to 1591 and is surrounded by a lively bazaar and numerous mosques and palaces. This morning we will enjoy a leisurely walk through the area. We will stop to admire the colorful tile mosaics found inside the Badshahi Ashurkhana. This Royal House of Mourning was built in 1595 as a congregation hall for Shia Muslims during Muharram.

The epicenter of this earthquake was Kanchanbari located in the Dhalai district of Tripura. The present study aims to assess the environmental and socio-economic impact of this earthquake in the vicinity of the epicenter. To assess and determine the level of damage, the affected areas were visited during the first week of the 2017 earthquake. Various Government offices were also consulted to acquire data on damages caused by the earthquake. Moreover, Remote Sensing and Geographical Information System (RS & GIS) techniques were applied to address the influence of this earthquake on bank erosion. During the field visit, the striking features of soil liquefaction generated by the earthquake were observed in the flood plain area of the Manu River. Landslide, with three casualties in India and the neighbor Bangladesh, and damages of infrastructure were also reported. Additionally, an assessment of the bank erosion study revealed that the rate of the post-earthquake bank erosion increased to 592%, compared to the pre-earthquake bank erosion within the study length of the Manu River.
