TEMPORAL VARIATION OF GROUND WATER QUALITY IN CENTRAL GODAVARI DELTA AND ITS SIGNIFICANCE IN HYDRODYNAMICS OF THE AREA
Journal Title: International Journal of Applied Engineering Research and Development (IJAERD) - Year 2017, Vol 7, Issue 3
Abstract
Central Godavari Delta is a Crop Intensive rice bowl of Andhra Pradesh. The present study area covers 16 mandals of East Godavari District of Andhra Pradesh. To study the temporal variation of Chemical Quality in terms of Electric Conductivity, 48 key observation wells were established and monitored the electric conductivity in the field. This shows a wide variation depending on the rainfall occurrence in the preceding season. Due to the less availability of surface water either in the form of rainfall, or in the form of canal water in the tail ends of the command area, farmers use ground water through filter points. Because of the ground water abstraction in the area, the fresh water - saline water interface was disturbed and the quality of ground water was deteriorated in the water stress periods. Hence, there is an urgent need for monitoring the fresh water - saline water interface, by constructing a purpose built observation wells with predefined monitoring parameters of level and quality with reference to depth. And, to assess the interface on a regular basis and prepare more robust ground water management plans for this area.
