This online document describes the water and chemical transport in soils of the southeastern USA. Contents include a geologic history of the southern United States, climate overview, land resources, land-use and land-cover, soils, flow and transport processes and examples of water and chemical transport in different parts of the southeastern USA.
Abstract from Article: "The persistence and movement of chemicals after application to a land surface in the southern region of the United States are influenced by geography, geology, climate, landuse/landcover, soil factors, chemical factors, and management factors. Relationships among these factors are grouped according to the major land resource areas (MLRA). An MLRA is a geographic associated land resource area that is characterized by particular patterns of soils, climate, water resources, and landuse. Factors that affect the transport of water and chemicals after application to a land surface in the southern region are described with emphasis on soil factors within an MLRA. Examples are presented of the persistence and movement of water and tracer chemicals in the dominant soils within an MLRA."
