Naryn basin, which has the largest river catchment area in Kyrgyz Republic and many mountain glaciers, is a huge ‘water tower’ for Kyrgyz Republic and Uzbekistan. Thus, the behavior of its glaciers has a large impact on water resources for the arid flat plain below, providing water for residents, irrigation, and energy in Kyrgyz Republic and Central Asia. We investigated the recent glacier condition in the Naryn basin (Chon Naryn and Kichi Naryn catchments) using topographic maps of 1:25,000 scale and ALOS/AVNIR-2 satellite imagery. For the 45-year period 1965–2010, glacier area decreased by 17.4% in the Akshyirak massif, and by 20.8% in the Borkoldoy, 21.9% in the Jetim, 24.6% in the Jetimbel, 28.9% in the Naryn, 20.8% in the Sook, 20.9% in the Teskey (south-slope glaciers), and 17.8% in the Uchemchek mountain ranges. The dramatic shrinkage was greater for south-facing than for north-facing glaciers, with respective area losses of 23.6 and 19.8%. The glacier shrinkage might affect not only irrigation water withdrawals during summer but also the planning of four cascade power stations to be constructed in the Chon Naryn and Kichi Naryn catchments.

The availability of water resources provides many benefits for the welfare of all human being. The Decrease of the availability of water resources is caused by various reasons, including as environmental damage of catchment area, human activities, land conversion, and the issue of global warming. The problems caused an increase in floods and droughts. Dam development can reduce the risk of flood and drought through a reservoir operation by using less water during rainy season and using much water during dry season. The sustainability of water resources in Way Sekampung can be identified by three main indicators, which are ecology, economic, and sosio-cultural by using the MDS (Multi Dimensional Scaling) analysis, There are two item become the focus of this research i.e. sedimentation and water balance. These factors are considered as the most important factors in planning a dam. Operationally, this policy will be applied by supplying water based on demand, strengthening water resources institutions, improving infrastructure facilities and developing technology.

The Impact

<div> <p>The impact of climate change on water resources through increased evaporation combined with regional changes in precipitation characteristics has the potential to affect mean runoff, frequency and intensity of floods and droughts, soil moisture and water supply for irrigation and hydroelectric power generation. The Ganga-Brahmaputra-Meghna (GBM) system is the largest in India with a catchment area of about 110Mha, which is more than 43% of the cumulative catchment area of all the major rivers in the country. The river Damodar is an important sub catchment of GBM basin and its three tributaries- the Bokaro, the Konar and the Barakar form one important tributary of the Bhagirathi-Hughli (a tributary of Ganga) in its lower reaches. The present study is an attempt to assess the impacts of climate change on water resources of the four important Eastern River Basins namely Damodar, Subarnarekha, Mahanadi and Ajoy, which have immense importance in industrial and agricultural scenarios in eastern India. A distributed hydrological model (HEC-HMS) has been used on the four river basins using HadRM2 daily weather data for the period from 2041 to 2060 to predict the impact of climate change on water resources of these river systems.&nbsp;</p> </div> <p>&nbsp;</p>

Based on the study, many years of information and analytical materials «Kyrgyzhydromet» and «Kazhydromet», as well as the Department of State Statistics of the Kyrgyz Republic and the Republic of Kazakhstan, characterizing the formation of water resources and their use in the economic sectors of the catchment area of the Shu River basin, were considered as a model of the "activity-natural system", which performs runoff, environment-forming, ecological and social functions and is the spatial basis of nature management for a comprehensive assessment of the state of the territory and water bodies. As a basis for assessing the main functions of the catchment area of the Shu River basin, a geosystem approach was used, which determines the scientific and practical feasibility of geomorphological schematization, within the framework of which it becomes possible to construct their ecological profile on a spatio-temporal scale, which makes it possible to establish trends in the development of cognitive and transformative activities that determine the direction and intensity of anthropogenic activity. in the region. The main natural function of the river basin of the formation of a hydrogeochemical flow, which has one object for its discharge, determines the qualitative state of the ecological profile of the catchment area of the Shu River basin, that is, depending on the zonation from the mountainous class of landscapes to the lowland class of landscapes (superaquial and subaquial facies), natural hydrological facies are gradually disrupted. rhythms, affects the hydrogeological and soil-reclamation processes and environmental conditions, especially in the lower reaches of river basins, which are zones of storage of return (collector-drainage and waste) waters of industrial and agricultural facilities.

Abstract. The geologic record of mountain glaciations is a robust indicator of terrestrial paleoclimate change. During the last glaciation, mountain ranges across the western U.S. hosted glaciers while the Cordilleran and Laurentide ice sheets flowed to the west and east of the continental divide, respectively. Records detailing the chronologies and paleoclimate significance of these ice advances have been developed for many sites across North America. However, relatively few glacial records have been developed for mountain glaciers in the northern Rocky Mountains near ice sheet margins. Here, we report cosmogenic beryllium-10 surface exposure ages and numerical glacier modeling results showing that mountain glaciers in the northern Rockies abandoned terminal moraines after the end of the Last Glacial Maximum around 17–18 ka and could have been sustained by −10 to −8.5 °C temperature depressions relative to modern assuming similar or drier than modern precipitation. Additionally, we present a deglacial chronology from the northern Rocky Mountains that indicates while there is considerable variability in initial moraine abandonment ages across the Rocky Mountains, the pace of subsequent ice retreat through the Lateglacial exhibits some regional coherence. Our results provide insight on potential regional mechanisms driving the initiation of and sustained deglaciation in the western U.S. including rising atmospheric CO2 and ice sheet collapse.

These tests were performed at the Technical University of Athens, Department of Water Resources, by Assistant Professor Alexandra Katsiri during November-December 1988. The problem she was asked to investigate was in what ways these waters differed from ordinary drinking water in Athens. (I am extremely grateful to her for this gracious assistance.) The waters were gathered from three separate sites in and near the Asklepieion on the south slope of the Acropolis, Athens (Fig. 18.5). Specifically, they are: A. Sacred Spring in Asklepion B. Archaic shaft immediately west of Asklepion C. Byzantine cistern immediately adjacent to B, to the west Table 19.1 gives a detailed analysis of the water samples. The fact that the figures from the three sources differ significantly indicates that the three places derive their water from different channels within the Acropolis. Thus the belief of the workmen on the site that these are different waters has been verified.

The World

The Aravalli range is one of the oldest mountain ranges in the world. Many lakes are sustained by the streams generated from the Aravalli range. In the last few years, hill systems are facing changes affecting the catchment of water bodies. Many waterbodies that were earlier able to provide water in peak summers are now dried up before the summer. The study aims to analyse land use land cover change in the Aravalli range on Sambhar Lake. Sambhar Lake is the largest inland saltwater lake in India and was selected as a “Ramsar Site.” A catchment area of the lake is delineated, and micro-watersheds are selected for detailed analysis. A primary survey is done to know the impacts and causes of changes in the lake. The study indicates significant green cover changes in three seasons over the years. Because of the loss in green cover, the soil is losing its moisture, affecting the cropping pattern and agriculture production in the area. Factors causing the drying of the lake are affecting its ecosystem and the number of birds coming to it.

Institut Teknologi Sepuluh Nopember (ITS) Campus, with the area of 167.4 Ha, is located within Surabaya coastal region in the eastern part of Java Island. It has initial characteristic with wetlands and swamps ecosystem. As a science and technological university, with the main acitivities in teaching, experimental laboratory works, and student activities, ITS is, currently, using ± 49% of its total vast area as building blocks for supporting academic facilities. Being a campus in a coastal zone, the commonly main problems are high porous soil, brackish surface water, high level of ground water, an obstructed drainage tendency because of delicate slant, and low catchment capability. This paper provides an action program on how ITS manage water resources within campus area in order to suppress environmental damage. Many steps had been taken into account for water catchment role, for instance: maintaining the catchment area on the main ITS master plan, planning catchment pond, surface water stabilization by preventing ground water usage, interrupting drainage water flow as being directly discharged into the city drainage system, rain water harvesting, and also designing floating floor for buildings.
