Abstract: |
A farm reservoir having size 27.00 meter 18.00 meter with maximum depth limited to 2 meter at Regional Agricultural Research Station, Khajura, Banke, Nepalgunj was dug during 2001 . Prior to its construction, the site was identified from a team of experts including NARC scientists, Indian consultant and expatriate from Bangladesh. The maximum capacity of pond to collect rainwater is limited to 9, 72, 000 liters. The weekly observations were taken for retained rainwater depth from June 9, 2004 to May 21, 2006. It was recorded that maximum retained water depths were 138 em during July and 195 em during September in 2004 and 2005 respectively. Even during dry periods in April, the reservoir was not completely dry and depth of retained water was 15 em. The rainwater was collected through the conveyance arrangement from the catchment area of about 7.5 ha. The texture of soil in the reservoir was sandy silt containing 65. 7% sand, silt 24.03% and clay 10.23%. The on farm reservoir was initially designed to provide supplementary irrigation especially for the wheat crop. Other crops such as rice and vegetables crops could also be irrigated. From this study, it can be concluded that the site is very suitable and has very good potential for rainwater harvesting as no other sealing materials were used in th~ reservoir to conserve water. It is proposed that further studies should be carried out by replicating the reservoirs in farmer's field having similar soil strata, which don't need any sealing materials for conserving watc;r. |
