Abstract:

A study was undertaken to evaluate the groundwater potentiality and performance of a shallow tubewell at haor areas under Netrakona district. For this purpose, a shallow tubewell was installed under the project ‘LIFCHASA” being carried out by the Bangladesh Agricultural University (BAU). The borelog data were collected and analyzed for different layers and distribution of formation materials. The aquifer borelog was stratified with silt loam (0 to 7 m), loam (7 to 14 m), clay loam (14 to 21 m), and fine sand (21 to 120 m). Total depth of the shallow tubewell was 32 m. The values of pump efficiency, delivery performance ratio, water delivery performance, and conveyance loss ratio were found as 34%, 34%, 33%, and 0.40, respectively. The formation material of the aquifer was found mainly fine sand. The tubewell was used to irrigate the fallow land where the farmers of the concerned selected haor area could not cultivate due to lack of irrigation facilities. These tubewells are being used successfully for irrigation purposes and, consequently, the farmers are making substantial profit from their farm products. The neighboring farmers were motivated and encouraged from the success of the LIFCHASA tubewell and installed four new STWs within a very short time.
