How science is tackling Pakistan`s water shortages
Efforts are underway to preserve Pakistan's water supply as climate change, population growth and a stressed irrigation system take their toll. Water availability per person has already fallen by more than 500 per cent since the 1960s and is likely to decrease even further to just 550 cubic metres by 2025 — compared with the 9,800 cubic metres currently available in the United States, for ...

Oil Skimmers’ model 6V oil recovery system is efficient by continuously removing waste oil
The Model 6V oil recovery system from Oil Skimmers Inc., the leader in oil skimming solutions and equipment, efficiently removes oily wastes that float on the surface of water. A specially formulated collector tube skims oil from the water surface. The oil adheres to the outside of the closed-loop tube, which is slowly drawn across the surface of the water and into the oil skimmer. The tube is ...

New model simulates US groundwater and surface water interactions
A new model to simulate groundwater and surface water interactions has been released by the U.S. Geological Survey (USGS). The groundwater and surface water FLOW (GSFLOW) model simultaneously accounts for climatic conditions, runoff across the land surface, subsurface flow and storage, and the connections among terrestrial systems, streams, lakes, wetlands, and ground water. 'GSFLOW can be used ...

Featured Product: Evaluating the Source of Water to Wells Using Metamodeling
Numerical groundwater modeling is a strength of the USGS, from software development (likeMODFLOW) to applications, such as the regional groundwater availability studies highlighted in the December 2015 News and Highlights. Numerical models are our most powerful tools for decision making. But these models require expertise to operate and require significant computational resources. Natural ...

Groundwater availability detailed in California`s Central Valley
A new, three-dimensional water-modeling tool provides a detailed picture of how water flows below ground and how it relates to surface-water in rivers and canals in California’s Central Valley. The Central Valley Hydrologic Model, developed by scientists at the U.S. Geological Survey, is available for use by water managers and other agencies. The model was designed to help resource agencies ...

New risks identified for aquatic wildlife from plastic compound
New evidence suggests that the adverse effects on aquatic ecosystems of chemical compounds used in the manufacture of plastics are greater than previously thought. The study reviewed data on five substances with known endocrine-disrupting effects on wildlife in rivers and waterways. Compounds such as bisphenol A (BPA), and the phthalates DBP, DEHP, DIDP and DINP2, are known as endocrine ...

Screening soil moisture conditions reveals an increased risk of drought in a Swedish drainage basin
The risk of drought in the Norrström drainage basin, Sweden, increased during the 20th century, a new study has found. As the frequency of the dry periods increased, less water was available in the landscape for agriculture and for the resupply of groundwater — despite an increase in precipitation in the area over the same period. The researchers reached this conclusion after screening ...
