The Estero de Domingo Rubio wetland, located near the Marismas del Odiel Natural Area in the Huelva estuary, is regionally, nationally and internationally protected thanks to its ecological value. However, its tributary rivers and the Ría de Huelva estuary pump manmade pollutants into it, which could affect its water quality and ecosystem. Industrial activity, accumulations of dangerous waste, the expansion of farming, and excessive extraction of sand and gravel for the...

By Don Comis, ARS Rain gardens are increasingly popular with homeowners and municipalities and are mandatory for many communities nationally. U.S. Department of Agriculture (USDA) scientists are finding ways to improve rain gardens so they not only reduce runoff, but also keep toxic metals out of storm drains. Rain gardens are plantings in depressions that catch stormwater runoff from sidewalks, parking lots, roads and roofs. Rain gardens come in various shapes and sizes, from large basins...

Estimating the long-term impact of agriculture on land is tricky when you don't have much information about what a field was like before it was farmed. Some fields in Missouri started producing crops more than a century ago"”long before anyone kept detailed records about the physical and chemical properties of the soil in a field. Researchers can't go back in time to revisit old fields in their pristine state, but a University of Missouri graduate student did perhaps the next best...

HARRISBURG, Pa., Sept. 24 /PRNewswire-USNewswire/ -- Agriculture Secretary Russell C. Redding today reminded Pennsylvania producers to plant cover crops this fall to keep beneficial nutrients in the soil and reduce nitrogen runoff into local waterways, including the Chesapeake Bay watershed. By planting cover crops--a small grain crop planted in the fall--producers reduce soil erosion, improve soil quality, decrease nutrient leaching, suppress weeds and attract beneficial pests....

Snowmelt in the Colorado River basin is occurring earlier, reducing runoff and the amount of crucial water available downstream. A new study shows this is due to increased dust caused by human activities in the region during the past 150 years. The study, led by a NASA scientist and funded by the agency and the National Science Foundation, showed peak spring runoff now comes three weeks earlier than before the region was settled and soils were disturbed. Annual runoff is lower by more than...

Erosion
2013-04-01 12:48:39

Erosion is the process by which rock and soil are taken from the surface of the Earth by exogenetic processes like wind or the flow of water, and then transported and deposited in another location. While erosion is a natural process, human activities have increased by 10 to 40 times the rate at which erosion is happening globally. Excessive erosion results in problems such as desertification, decreases in agricultural productivity because of land degradation, sedimentation of waterways,...

The water cycle (or hydrologic cycle) describes the continuous movement of water above, below, and on the planet. Since the water cycle is in fact a "cycle", there is no beginning or end. Water exists in three states: liquid, vapor, and ice. Although the balance of water on our planet is fairly constant, individual water molecules may come and go. The water cycle is driven by the sun. The sun heats the oceans and allows water to evaporate into the air. The sun also heats snow and ice which...
