Extraction of Drainage Pattern and Watershed from SRTM Data Using GIS Tools: A Case Study
Abstract: This paper proposes a fast and an inexpensive method for delineating the drainage and watershed of a sub-basin. Planning of the water resource management is evolving from simple local-scale problems toward complex spatially explicit regional scale. Such problems have to be addressed with distributed models that can compute runoff and erosion at different spatial and temporal scales. In general, watershed can range from as little as one hectare to hundreds …

Land Resource Evaluation and Site Suitability Criteria Development around the Shivpuri City (M.P.), India, Study using Remote Sensing and GIS
Abstract: Recent research indicates that the human induced conversions and modifications of land cover around the Shivpuri city. Land resource evaluation and Site suitability, though land use is mainly controlled by various biophysical factors like soil, climate, relief and vegetation but the human activities are mainly responsible for the change of attributes of land use modification and conversion. In this paper focuses on weightages overlay GIS techniques for land resource evaluation …

Two-Dimensional Flood Modelling of Majuli Island, Assam (India) using MIKE FLOOD Model
Abstract: Flood hazard mapping, which uses model and satellite remote sensing data, is extremely useful for flood monitoring and risk management. The flood inundation extent and flooding depth on Majuli Island and its surrounding area in Assam, India, were simulated using MIKE FLOOD, a coupled 1D-2D hydrodynamic model. MIKE FLOOD is a platform that integrates the MIKE Hydro River (1D) and MIKE 21 FM (2D) models into a dynamically coupled single …

Geo-chemical Analysis of Arsenic in Medium Aquifers and Its Relation with Physical Parameters: A Study of Ballia District, India
Abstract: The main objective of this paper is to assess the spatial variation of arsenic (As) in medium aquifer and to relate it with surface elevation and slope generated using Shuttle Radar Topography Mission (SRTM) satellite data and water table. Water samples were collected in both pre- and post-monsoon season in 2011. The analysis of water samples for As were carried out by using atomic absorption spectrophotometer (AAS). Total 33 water …

An Assessment of CartoDEM v1 over National Capital Region of India
Abstract: The most reliable and common source of elevation information for a given region has always been topo-sheet maps. However, other sources of elevation are now freely available with the advancement in the technology. SRTM DEM and ASTER DEM are the best examples of such freely available elevation sources. Still there is constantly a demand of better elevation data among the users. Recently, National Remote Sensing Center, India released CartoDEM v1. …
