Development of Rain Gauge Station in SGI Campus

Abstract

Hydrology study of water and its properties, including its distribution and movement in and through the land areas of the earth. The hydrologic cycle consists of the passage of water from the oceans into the atmosphere by evaporation and transpiration (or evapotranspiration), onto the lands, over and under the lands as runoff and infiltration, and back to the oceans. Hydrology is principally concerned with the part of the cycle after the precipitation of water onto the land and before its return to the oceans; thus meteorology and oceanography are closely related to hydrology. The study area which located in the survey of India Toposheet Nos.47L/5 & 47L/6 is present in the Kolhapur district of Maharashtra which also uses the LISS-III satellite image. The data base is created using various techniques. The maps which are prepared by Geo referencing and digitization from SOI Toposheet and LISS-III satellite image using QGIS2.6.1 -Brighton software. The Survey of India Toposheet scale 1:50,000 and LISS-III satellite image are used for preparation of the slope, catchment area and contour. The main aim of the proposed study is to establish proper rain gauge station as there is no rain gauge station in the nearby vicinity. As SGI campus is located in the hilly region it is appropriate sit for establishment of rain gauge. But to do this it is important to carry out survey of entire campus for proper location of gauge station this survey. This is carried out by using QGIS software, counters are plotted and fixed the location of the gauge station. The proper type is suggested as Tipping bucket. Then by available rainfall data by using Thiessen polygon method the attempt is made to calculate precipitation at proposed gauge possibly may get collect.
