Abstract
Inadequacy of water for the irrigation purposes is being reported as the remarkable problem from the farmers. The groundwater and well systems have to be promoted where the construction of dams, reservoirs, canals, etc. alone can’t serve the farmers. In this study, an attempt has been made to develop to draw water efficiently, to the ring wells situated along the bank of a river. A ring well was selected as the prototype along the river bank and the physical properties of the soil along the periphery of the well were determined to know the soil profile around the well. A model was simulated accordingly and the yield of the model was determined by conducting recuperation tests. Further, perforated laterals of two different lengths were inserted in eight radial directions alternatively at the bottom of the well, and yield was measured for various combinations of the laterals. Similarly, the recuperation tests are conducted even for the slotted laterals and compared with that of the perforated ones. The yield of the model without laterals and with laterals has been compared to know the efficiency of the model. The combination of laterals which gives the optimum yield in the model was selected and provided in the prototype. From the present study, it can be concluded that usage of laterals increases the permeability of the system and thereby increases the yield of the well without the need for increasing the cross section of the well and thus saving valuable time and money.
