Three Global Climate Models (GCMs) output (precipitation and temperature), bias corrected with the WATCH Forcing Data (WFD), for the A2 and B1 scenarios, are used for drought assessment at a basin scale. The HBV model produced results for flow, soil moisture and groundwater reservoir and shows that decreasing hydrological parameters will result to increasing drought duration. Future scenarios e ... read more >>
Florida is having success using Aquifer Storage & Recovery (ASR) technology to manage its water. This is important because it is a fresh frontier in sustainable water management in areas where water sources are temporally variable and/or stressed. ... read more >>
Global water resources modeling with an integrated model of the social–economic–environmental system
Awareness of increasing water scarcity has driven efforts to model global water resources for improved insight into water resources infrastructure and management strategies. Most water resources models focus explicitly on water systems and represent socio-economic and environmental change as external drivers. In contrast, the system dynamics-based integrated assessment model employed here, ANEMI, ... read more >>
In the global aftershock zone that followed the major April 2012 Indian Ocean earthquake, seismologists noticed an unusual pattern. The magnitude (M) 8.6 earthquake, a strike-slip event at intraoceanic tectonic plates, caused global seismic rates of M≥4.5 to rise for several days, even at distances thousands of kilometers from the mainshock site. However, the rate of M≥6.5 seismic activity subseq ... read more >>
1. A comparison of two papers describing methane pollution of groundwater wells near fracking operations
2. Concludes that groundwater pollution from shale gas extraction is dependent on local geology
3. Mechanisms of pollution transport from fracking wells to groundwater are poorly understood
4. Further study is required into the factors contributing to pollution from shale gas extraction ... read more >>
1. A new Indian study shows groundwater depletion common in Kerala, like Punjab and Tamil Nadu.
2. This is important because agriculture, wetlands and drinking water supplies all depend on groundwater.
3. This is linked directly to course content since groundwater depletion is discussed in class.
4. reduce rate of groundwater usage through changes to policy and agricultural pra ... read more >>
Scientists have studied the rates of basal melt, or the melting of the ice shelves from underneath, of individual ice shelves, the floating extensions of glaciers that empty into the sea. But this is the first comprehensive survey of all Antarctic ice shelves. The study found basal melt accounted for 55 percent of all Antarctic ice shelf mass loss from 2003 to 2008, an amount much higher than pre ... read more >>
Regions depending on winter snowpack for hydroelectricity generation may be adversely affected if spring temperatures increase. An inverse relationship between spring temperature and summer hydroelectricity generation is complicated by changing statistical properties of the variables involved. We use simple approaches to quantify, within broad limits, the effect of a change in spring temperature ... read more >>
In San Carlos, hot springs have been used to help show the medical usages of water as well as to help bring in tourism. Before the plan of site, American Association of Spas and International Thermal Tourism was consulted. Which agreed that there is a need to help train more professionals in such medical knowledge. ... read more >>
