This atlas provides the details of glacial lakes present in the Ganga River basin including their hydrological, geometrical, geographical, and topographical attributes. The satellite data used and methodology followed in delineating the lakes are also discussed.
This technical note describes the data sources and methodology underpinning a computer system for the automated generation of land use/land cover (LULC) maps of urban areas based on medium-resolution (10–30m/pixel) satellite imagery.
Interacting storm surges and high water runoff can cause compound flooding (CF) in low-lying coasts and river estuaries. The large-scale CF hazard has been typically studied using proxies such as the concurrence of storm surge extremes either with precipitation or with river discharge extremes. Here the impact of the choice of such proxies is addressed employing state-of-the-art global datasets.
The pre-monsoon cyclone Viyaru in the Bay of Bengal during May 2013 traversed a long track from 5°N to 22°N over 7 days with basin-wide response, which was well captured by the time series observations of OMNI buoy network along with satellite data.
Kerala filed its action plan on restoration of water bodies in compliance of the National Green Tribunal order of February 25, 2020 in the matter of Lt. Col Sarvadaman Singh Oberoi Vs Union of India & Others to the Central Pollution Control Board. The NGT had sought information from all states and Union Territories on water bodies – its identification, protection and restoration.
Action taken report on behalf of Ministry of Environment, Forest and Climate Change in the matter of Legal Aid Committee, NGT Bar Association Vs Ministry of Environment, Forest and Climate Change & Others. Report filed on March 18, 2020.
Urban areas are currently responsible for ~70% of the global energy-related carbon dioxide (CO2) emissions, and rapid ongoing global urbanization is increasing the number and size of cities. Thus, understanding city-scale CO2 emissions and how they vary between cities with different urban densities is a critical task.
Water temperature is critical for the ecology of lakes. However, the ability to predict its spatial and seasonal variation is constrained by the lack of a thermal classification system. Here we define lake thermal regions using objective analysis of seasonal surface temperature dynamics from satellite observations.
