Water quality studies of Lake Nainital and surroundings – A research report by National Institute of Hydrology
Posted on 08 Jul, 2010 09:57 PMThe report provides an account of the findings of water quality studies of Lake Nainital and surroundings. Even though quite a few water quality investigations have been conducted by other researchers, they were more focused on biological aspects and overlooked the hydrological aspects. Further, not all of the earlier studies on Nainital incorporated the groundwater quality aspects, which are essential to establish the background values that can be ascribed to the geology of the region. Only after establishing these, the pollution levels can be assessed.
Study of Lake Nainital: Groundwater interaction using Isotope techniques - A research report by National Institute of Hydrology
Posted on 25 Jun, 2010 12:03 AMThe study undertakes hydrological investigations to develop a conceptual model for the water balance of Lake Nainital in Kumaon Himalayas. All the components of lake water balance, except the sub-surface ones, have been measured or estimated using standard methods like isotope mass balance method in conjunction with the conventional water balance method. The sub surface outflow from the lake was assessed by studying the hydraulic interconnection of the lake and downstream springs using environmental tracers.
A hydrological study of Lake Nainital – A research report by the National Institute of Hydrology
Posted on 22 Jun, 2010 08:06 AMThe hydrological study develops a water balance of the Lake Nainital to facilitate the utilization of its water in a planned and systematic manner. The lack of knowledge of input and output parameters such as subsurface inflow, use of lake water for domestic and industrial purposes, evaporation loss and leakage from lake including the outflow through sluice gates had created uncertainty in determining the availability of water in the lake. The study attempts to understand the behavior of the input and output parameters in detail by using both conventional and isotopic techniques.
The lake meets the local drinking and domestic water needs and is for the most part fed by rainfall during monsoon and by inflow from perennial springs and subsurface inflow during the non-monsoon season.
