Fluctuation of groundwater in an urban coastal city of India: a GIS‐based approach

Abstract

Abstract:Groundwater is the most important and valuable natural resources especially in coastal urban environment where surface water is insufficient to satisfy the water requirement. Puri city is located on the east coast of India where groundwater is the only source available to meet city water supply. As the city is situated on the sandy aquifer, quality of groundwater is deteriorating because of anthropogenic activities, lack of sewerage system, etc. The objective of the study was to assess the groundwater fluctuation during post-monsoon and summer with respect to hydrogeological conditions, topography, and groundwater consumption pattern of the city. For this assessment and analysis, Geographic Information System (GIS) was used to visualize topography of the area through digital elevation model (DEM) and distribution of groundwater contours spatially and temporally. The probable areas prone to contamination were identified based on aquifer property and depths to water table below ground.

GIS-Based Method for Estimating Surficial Groundwater Levels in Coastal Virginia Using Limited Information

“…Few published studies are available that used GIS and RS technologies to quantitatively estimate groundwater levels with limited information, short of a hydrogeologic modeling study. Vijay et al (2011) used kriging to interpolate the water table surface from water elevations measured at 35 production wells north of the Bay of Bengal in India and used it to characterize seasonal water table fluctuations. Direct interpolation of water table measurements is ideal when data are sufficiently dense, but indirect methods must be used when monitoring data are sparse.…”
