Abstract
This paper investigates the feasibility of managed aquifer recharge [MAR] for Southwest Kansas. Multiple sources of water for MAR were investigated. The sources of water analyzed were stormwater runoff from fields, use of low flow or ephemeral streams, and use of a regional river for infiltration water. The use of the Arkansas River was found to be the most viable source of water in this area. Different methods of MAR were evaluated with the most feasible selected for this local area. The construction of infiltration basins in existing sand mines was found to be the best MAR alternative in this region. The requirement for the retirement of sand mines set out by the State of Kansas comports with the requirements of infiltration basins, and there exists a local ditch system that can convey Arkansas River flows to the infiltration basins with little need of new construction. The salinity of the Arkansas River is of concern as it could reduce crop yields if used for irrigation. This risk could be mitigated by crop choice or other means. This investigation is also relevant throughout the State of Kansas, so perhaps another river would have more suitable conditions.
