The present paper tries to investigate the potential flood mapping techniques. Conventionally use of traditional methods is adapted for flood plain mapping. But this paper focuses on the use of GIS and RS techniques. DEM is initially produced and then processing methods as per the data used is done. From the literature it is observed that 3D modelling using HEC-RAS is a dominant and most appropriate method for the analysis of the flood maps. This case study is applicable for Western Maharashtra Region (Kolhapur, Satara and Sangali). However it is noted that the use of these tools depends on the availability of data. Better resolutions of the satellite image can be used, but the limitation is that cost will increase. Also, using GIS and RS techniques will help in better updating of these maps. This paper describes the flood prone Pre-flood management areas of India along with the flood prevention and management techniques in western Maharashtra region. In this paper researcher focus on to study Rainfall Variability in Kolhapur,Satara and Sangli District and to study and analyze of pre- flood management at western Maharashtra region (Kolhapur, Satara and Sangli).Analyze Flood Management Measures Practiced in India and to Study and analyze detection methods are used for remote sensing the disasters. To Study and analyze Geographical information system (GIS) provides spatial data management and analysis to study flood management. Historically floods are known to cause damage to property and life leaving a long term traumatic impact on those who get affected by them. The intensity and magnitude of floods is supposed to be increasing world over in the recent decades because of climate change and global warming phenomenon. The Western Ghats are globally important, not only being rich in biodiversity, but primarily because of the role, they play in influencing climatic regime and annual precipitation in Indian subcontinent. The climate change has caused uncertainty and wide fluctuations in precipitation pattern from extreme droughts to heavy rains and periodic cloud bursts. Thus, floods, which were locally almost unknown, are becoming a potential disaster in the earlier relatively safe and climatically stable areas such as Western Ghats. Kolhapur district being largely i.e. over 65- 70% of the total area, being situated in the Western Ghats region, receives high annual rainfall in its western hilly part. It was therefore felt necessary to study the region for vulnerability and risk analysis of annual floods in Kolhapur district to know their main causes and their consequences. Therefore, this paper deals with the relevant topics such as rainfall variability in Kolhapur district, correlation and multiple regression analysis of rainfalls and water levels in flood prone Panchganga basin. It also includes readings on drinking water quality from Panchganga river basin, during pre and post flood period and people‟s perception on the issue through social Impact assessment (SIA) studies.
