Arkansas Groundwater Management Via Target Level, Richard C. Peralta, Ann W. Peralta
Arkansas Groundwater Management Via Target Level, Richard C. Peralta, Ann W. Peralta
Civil and Environmental Engineering Faculty Publications
AN approach to groundwater management by maintaining "target" groundwater elevations is presented. A finite difference form of the Boussinesq equation is proposed as a means of determining the groundwater withdrawals that will maintain those levels in the long term. This spatially distributed pumping can represent a sustained yielding pumping strategy. A sample pumping strategy is presented for the Arkansas Grand Prairie. Such a strategy is applicable under a variety of legal systems. It represents an especially attractive alternative for riparian rights states (like Arkansas) where effective groundwater management without radical changes in the basic water rights system is desired.

Groundwater is the major source of water for consumptive use in Arkansas. Significant pumping is concentrated in areas of agricultural and industrial production. In a number of these areas, including much of the Grand Prairie region of Arkansas, average annual withdrawal from the aquifer exceeds recharge. As a result of this groundwater mining, water levels are dropping. Mining which leads to excessive declines in the water level can accelerate salt water intrusion in an aquifer, cause aquifer compaction, make irrigation economically unfeasible, and eventually disrupt an economy based upon groundwater. Generally, these problems can be prevented or limited by maintaining …

The Arkansas Grand Prairie has been a major rice producing area for most of this century. The irrigation water required for rice, and at the present time, for soybeans, is primarily obtained from a Quaternary aquifer. This extensive formation underlies much of eastern Arkansas as well as parts of other states. Groundwater enters the Grand Prairie region from extensions of the aquifer lying outside of the area. Prolonged pumping of water from the aquifer at a rate exceeding the recharge rate has significantly reduced Quaternary groundwater levels in the Grand Prairie.
