   Integrated Spatial Platform for Better Flood Management and Mitigation for Local Governments: A Geospatial Approach

   In this era of climate change induced frequent flooding, proper management of flood events are assuming greater importance with each day for government authorities. As far as the better flood management is a concern, there is an increasing trend towards to adopt the non-structural approach which is less costly and more effective in comparison with structural measures. The latest technical tools such as GIS incorporated with super computer systems have come with a real boon towards better flood management for government administration. In order to explore the best capabilities of such kind of integrated systems for better flood management, an Integrated Flood Management System (IFMS) is proposed in this writing incorporating GIS and super computer platform. This system illustrates the functional utilities such as flood situation monitoring, damage estimation and analysis, decision support system and finally the action plan development for better flood management. This system will allow taking inputs from both spatial and non-spatial data including physical, socio-economic and socio-cultural data, flood-related data pertaining to the district and taluka. This study has also proposed the steps of action plan development through the integrated system at the administrative and individual level.

   Morphometric Analysis of Adula River Basin in Maharashtra India using GIS and Remote Sensing techniques

   Amit Bera, Bhabani Prasad Mukhopadhyay, Debasish Das

   The present paper attempts to study the morphometric characteristics of Adula River Basin in Maharashtra using GIS and Remote Sensing technique. Topographical maps and ASTER DEM data at 30m spatial resolution have been used for the analysis. Stream networks, different linear, areal, and relief aspects of the basin were analyzed using Arc GIS 10.1 software. The drainage pattern of Adula River is dendritic to sub-dendritic type, with 4th order stream. The mean bifurcation ratio is 5.36, which indicate uniform lithology in the basin. The elongation ratio and circulatory ratio shows elongated shape of the basin. Low length of overland flow (0.63) of the basin is the indicator of moderately low surface runoff. Estimated drainage density (0.79 km/km2) and drainage texture (0.84) of the River basin indicates highly resistant or permeable subsoil material with coarse to moderately coarse drainage texture. The relief aspect of the Adula basin reveals that the major part of the basin has low to moderate relief and values of dissection index and ruggedness index both were very low.
