There is a severe warning of groundwater pollution in the coastal district of Purba Medinipur, West Bengal. This is due to ingression of saline water intrusion. A top stratum of the soil in coastal area of the district is found to be made of different layer of clay and sand of sea origin. The groundwater cannot be used for domestic, irrigation or industrial purposes. As a result of continuous extraction of water, the groundwater is formed like a cone of depression. It has resulted in redundant well and therefore the water extraction has become uneconomical due to augmented lift. All these necessitate for urgent measures to control the ingression of salt water into the coastal aquifers. Some measures to control the encroachment of salt water are suggested in this paper.Keywords

A laboratory experiment was conducted by placing a 50 mm diameter horizontal cylinder across the flow and a 50 mm wide vertical plate at 55 mm downstream of it in a flume to observe and compare the surrounding flow fields past these structures. The cylinder vertical position was altered from 0.3 to 0.4 times of flow depth of water. Around these structures, the obtained flow fields, vortex formation, and turbulent characteristics are analyzed, compared and discussed.Keywords

Oscillating hydraulic jump experiments were conducted by increasing the temperature of water from minimum to maximum within a range of measurement. By varying temperature from 32-40°C, different jump characteristics were observed and noted. The varying temperature was measured throughout the jump profiles and dependence of jump parameters with varying temperature is measured and quantified. This study may find applications where a changing stream water temperature significantly affects the jump characteristics.Keywords

Arsenic found in contaminated saltwater has very serious side effects. Purba Medinipur was free of arsenic until 2009. Present study verifies whether the coastal areas of Purba Medinipur, after 2009, were arsenic contaminated. From Contai, Digha, and Egra regions, 97 bore wells were selected to collect groundwater samples and analyze arsenic contamination. Few areas have shown the presence of arsenic in groundwater. However, the concentration in many areas is found to be below the permissible limit of drinking water.Keywords
