Climate and Water Cycle in Toilets

Lack of toilets and safe water in health-care facilities

Editorials 210 In March 2015, the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF) released a report 1 on the status of water and sanitation in health-care facilities from 54 low-and middle-income countries. Data representing 66 000 health facilities show that water was not readily available in about 40%. 1 Over a third of facilities lacked soap for hand washing a...

Climate change and the water cycle in newly irrigated areas.

Climate change is affecting agriculture doubly: evapotranspiration is increasing due to increments in temperature while the availability of water resources is decreasing. Furthermore, irrigated areas are expanding worldwide. In this study, the dynamics of climate change impacts on the water cycle of a newly irrigated watershed are studied through the calculation of soil water balances. The stud...

9.4 Using Clustered Climate Regimes for Understanding Water Cycle Variability

A multivariate statistical clustering technique— based on the iterative k -means algorithm of Hartigan (Hartigan, 1975)—has been used to extract patterns of climatological significance from 200 years of general circulation model (GCM) output. Originally developed and implemented on a Beowulf-style parallel computer constructed by Hoffman and Hargrove from surplus commodity desktop PCs (Hargrove...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
