REMODELING OF DEEP TUBE WELL SETTING ENHANCING IRRIGATION EFFICIENCY AND ENVIRONMENTAL SAFETY AND BIODIVERSITY IN BANGLADESH (Pages : 61 - 65)
S. TALUKDERA study was conducted on the Remodeling of Deep Tube Well (DTW) setting to increase irrigation and water use efficiency saving the natural environment specially the use of underground water in Bangladesh. The work was done with the specific objective to identify the problems relating DTW irrigation and its probable bio-hazards and on eco-environment and to develop a DTW setting model as to overcome the situation. The work covered 4 regions distributed over the country having potential of different underground water table and intensity of water use. The results showed that the movement and storage of the aquifer in deeper strata is not so good for installation of DTW having higher water lifting capacity. Ground water level status was found to be greatly improved by augmented rechargeable water from surface water irrigation or from other sources like rain water. During and after irrigation the effects of ground water table should be reviewed time to time during the process of implementation and based on the actual impacts the project activities particularly trend of water table fluctuation needs to be monitored to avoid adverse impacts on ecology. Artificial recharge to improve ground water, specially in the northern region area is strongly recommended which experiences were taken in this study is and thus a model has been developed which can improve the situation by up to 25%. However, further hydro-engineering studies are required to confirm the present findings.Download
