Randall J. Hunt, John F. Walker, William R. Selbig, Stephen M. Westenbroek, R. Steve Regan
2013, Scientific Investigations Report 2013-5159
Although groundwater and surface water are considered a single resource, historically hydrologic simulations have not accounted for feedback loops between the groundwater system and other hydrologic processes. These feedbacks include timing and rates of evapotranspiration, surface runoff, soil-zone flow, and interactions with the groundwater system. Simulations that iteratively couple the...
Reconnaissance investigation of the rough diamond resource potential and production capacity of Côte d’Ivoire
Peter G. Chirico, Katherine C. Malpeli
2013, Scientific Investigations Report 2013-5185
Ethnic and political conflict developed into open civil war in Côte d’Ivoire in 2002, leading to a de facto partitioning of the country into the government-controlled south and the rebel-controlled north. Côte d’Ivoire’s two main diamond mining areas, Séguéla and Tortiya, are located in the north, under what was, until...

2013, Scientific Investigations Report 2013-5150
Groundwater from the surficial aquifer system and Upper Floridan aquifer in the Dougherty Plain and Marianna Lowlands in southwestern Georgia, northwestern Florida, and southeastern Alabama is affected by elevated nitrate concentrations as a result of the vulnerability of the aquifer, irrigation water-supply development, and intensive agricultural land use. The region...
The effects of artificial recharge on groundwater levels and water quality in the west hydrogeologic unit of the Warren subbasin, San Bernardino County, California
Christina L. Stamos, Peter Martin, Rhett R. Everett, John A. Izbicki
2013, Scientific Investigations Report 2013-5088
Between the late 1940s and 1994, groundwater levels in the Warren subbasin, California, declined by as much as 300 feet because pumping exceeded sparse natural recharge. In response, the local water district, Hi-Desert Water District, implemented an artificial-recharge program in early 1995 using imported water from the California State Water...
