Harvesting Excess water from the rivers of Little Tallahatchie, Big Sunflower, and the Buffalo.

Author(s): Madison, J.

Considerable research has been conducted to assess the potential for harvesting rainwater during the off- season in the South, particularly in the State of Alabama (Tyson, T.W., 1999). The correct management strategy for utilization of groundwater and surface runoff is proper allocation of water resources within a catchment. A management strategy utilizing levee embankment ponds for production and rainwater storage has been beneficial in reducing the amount of effluent discharge by as much as 90% and groundwater use by as much as 75% (Cathcart, 1999). Early research (Cathcart et al., 2007) pertaining to rainwater harvesting and storage technologies demonstrated the importance of the implementation of management strategies for conserving groundwater resources. This research will be based upon the utilization of excess floodwaters from Big Sunflower, Little Tallahatchie, and Buffalo rivers using modeling approaches of simulating floodwater capturing methodologies including the use of pumps, siphons, and diversion techniques of streams or rivers along the Mississippi River Basin to augment the water needs for irrigation during the growing seasons (Pote, J., et al. 1988). Additionally, this research will examine 64 years of precipitation data, flood stages, duration of flooding, and will utilize the use of rating curves and back calculations to determine missing data points in the precipitation and flow data records. Data will be obtained from the United States Geological Survey (USGS) and the Army Corps of Engineers (USACE) for the Big Sunflower, Little Tallahatchie, and Buffalo Rivers.
