Bathymetry Mapping and morphometric characteristics demarcation of Lake Manasbal, Kashmir valley, India using Echo Sounder and Geospatial Technology
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 7
Abstract
Bathymetry is a key element of surface water body, which includes the shape, area, volume and depth (N.Khare, et al., 2008 and N.Basos, et al., 2014). Bathymetry survey are maps that can be used to describe the lakes physical characteristics and also help in learn more about the effects of climate change on the environment. Bathymetry mapping in lake Manasbal using echo sounders forms first of its kind to prepare the bathymetry map and delineate various morphometry characteristics based on the geospatial survey. Bathymetry survey were carried out using Garmin 178 sounder and Global positioning system (GPS) to compute Longitude, latitude, depth and water temperature. This in turns helps in preparation of contour maps, morphometry maps and base maps. The Maximum depth of the lake is 43.2 feet, which is located at the wester part of the lake. Several morphometric parameters for the Manasbal lake has been computed which includes Maximum Length (3.4967 Km), Maximum Effective Length (3.4875 Km) Effective width or Mean Width (0.6545 Km), Relative Depth 4.35, Length of Shore line (10.0932Km) Shore Line Development (1.88) and the Total Lake Area (2.28 Sq Km).
