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 …

Urban Flood Hazard Modeling for Noida City
Abstract: This contemporary work unveils the usage of a new methodology to carry out an accurate hazard mapping of urban flood footprints. It is based on wetness transformation. It is a procedure of conversion of multi-spectral-bands into three dimensional feature space. The present study embraces conversion of thematic mapper (TM) imagery of Landsat to a three dimensional array; brightness, wetness and greenness, followed by the technique of change detection to locate …

A GIS Based Tool to Digitize Polygon and Line Segments of a Black and White Map
Abstract: In this paper a GIS based tool has been proposed to digitize polygon and line objects throughefficient usage of RGB values of the segments of raster maps. For digitization of polygon,initially a closed loop is drawn inside the polygon segment. Beginning from the initial point ofthe closed loop, eight connected pixels calculation is incorporated to obtain the pointsexisting in between the loop and the actual boundary. The points which exist …

Application of Remote Sensing and GIS Techniques for Decadal Change Detection of Mangroves along Tamil Nadu Coast, India
Abstract: Mangrove forests are among of the most productive and biologically important ecosystems of the world. The mangrove forests aids stabilize shorelines and reduce the devastating impact of natural disasters such as tsunamis and hurricanes. They also provide breeding and nursing grounds for marine and pelagic species, and food, medicine, fuel and building materials for local communities. Despite of its immense importance, it is declining due to increasing coastal population, urbanization …

GIS Based Spatial Analysis for Urban Water Supply: A Case of Kedamay Woyane Sub-City, Mekelle City, Ethiopia
Abstract: Access to drinking water supply is one of the universally recognized basic socioeconomic and environmental problems as it is one of the basic needs for human survival. However, this problem is more acute in developing countries like Ethiopia where there is absence and inequity distribution of drinking water access among the society. Nerveless, the problem is more serious in the country’s urban cities like Mekelle city, where the water distribution …

The Impact of Linear Infrastructure on Land Utilization using GIS
Abstract: In all urban centers of the Tigray region and the nation as whole, there is inefficient urban land utilization and development. The bottlenecks in the supply of serviced land are caused by inadequate provision of infrastructure and services. Moreover, the government often provides arterial infrastructure, leaving the provision of secondary and tertiary infrastructure to individuals or private sector developers. As a result private sectors or individuals assembled raw land only. …

Micro Watershed Delineation and Codification in Chickballapur District Using GIS Techniques
Abstract: Enhanced and reproducible methods for watershed modelling and assessment are essential tools for monitoring and management of watersheds. However, only few integrated studies propose advanced open source data and methodologies for watershed modelling and assessment. In this study, free downloadable DEM is processed using GIS tools to delineate watersheds through drainage map. Seven watersheds were identified in chickballapur district. Further sub watershed, mini and micro watersheds were delineated hierarchically. The …
