Managing the Urban Water Supply

Image
_NEW: follow the development of the new web-presence wolframscharnhorst.blogspot.com print download: http://bit.ly/185cRt9 Sustainable urban water supply represents a key issue today as well as in the near future. Often networks are out of date, leakage or plugging is a common issue and investments need to be considered very careful. In addition, the behaviour, i.e. the demand of the consumers varies strongly. The present issue of the Quarterly Notes on Sustainable Water Management (Q04/2014) – Managing the Urban Water Supply - tries to provide an overview of innovative articles addressing the above issues in-depth. As always, a summary of news about the development of the web-portal is given. In the fifth year of its operation the platform is subject to a thorough re-design. This implies that the former _kt75 | mirror ( http://kt75-mirror.blogspot.com/ ) is now integrated into the large information portal http://wolframscharnhorst.blogspot.com . Via th...

Aquifer Recharge: new GIS-solution to provide for sustainable water supply
Japanese Experiences (sci paper).

Image
_NEW: follow the development of the new web-presence wolframscharnhorst.blogspot.com reprint Vulnerability assessment to delineate areas that are more susceptible to contamination from anthropogenic sources has become an important element for sensible resource management and land use planning. This contribution aims at estimating aquifer vulnerability by applying the DRASTIC model as well as utilizing sensitivity analyses to evaluate the relative importance of the model parameters for aquifer vulnerability in Kakamigahara Heights, Gifu Prefecture central Japan. An additional objective is to demonstrate the combined use of the DRASTIC and geographical information system (GIS) as an effective method for groundwater pollution risk assessment. The DRASTIC model uses seven environmental parameters (Depth to water, net Recharge, Aquifer media, Soil media, Topography, Impact of vadose zone, and hydraulic Conductivity) to characterize the hydrogeological setting and evaluate aq...

Chinas Big Blue Challenge - Water

-- a _kt75 | reprint _NEW: explore all _kt75 | publications via the news db... and leave your comments here A crisis is developing beneath China’s thirsty farms and cities, but  no one knows its full extent. With about 20% of the world’s population but only about 5–7% of global freshwater resources, China draws heavily on groundwater. Those reserves are being depleted at an alarming rate in some regions and are badly polluted in many others,  warned experts last week at the International Groundwater Forum 2010 conference in Beijing. The scientists also warned that confronting the crisis will require dealing with other short - ages: of knowledge and regulation. They say that a nationwide network to monitor ground - water levels is urgently needed, and that the government should  improve data sharing, cut water waste and help farming become more efficient. “The water crisis is not unique to China,” says Frank  Schwartz, a hydrologist at Ohio State Uni...

Hot Spot I: China's Water Scarcity is Virtual

-- a _kt75 | reprint NEW: explore all _kt75 | publications via the news db... and leave your comments here Water footprints and virtual water flows have been promoted as important indicators to characterize human-induced water consumption. However, environmental impacts associated with water consumption are largely neglected in these analyses. Incorporating water scarcity into water consumption allows better understanding of what is causing water scarcity and which regions are suffering from it. _progress | M replaces _kt75 | mirror. visit: http://progress-m.blogspot.com . ready: 01.07.2015. close ✕ In this study, we incorporate water scarcity and ecosystem impacts into multiregional input-output analysis to assess virtual water flows and associated impacts among 30 provinces in China. China, in particular its water-scarce regions , are facing a serious water crisis driven by rapid economic growth. Our findings show that inter-regional flows of virtual water rev...

This is the two hundredth _kt75 | post since February 2010 and with a daily hit rate between 100 and 200 unique visitors the _kt75 | mirror appears to be a well-accepted source of information in a rather narrow niche: sustainable development with a focus on water management . However, even reliable entities like the _kt75 | mirror seem to be subject to some kind of censor-ship. Just recently the LinkedIN channel of the _kt75 | mirror was temporarily shut-down because of the following baseless accusations: phishing multiple contacting spamming Phishing was never done via _kt75 | mirror, neither multiple contacting. Remains 'spamming'. Now, it might be worth to clarify that the _kt75 | mirror is operated without any kind of (3rd party) advertisement.

Fracking: Report Cites Bad Wells for Tainted Water

Image
-- a _kt75 | reprint Download: Quarterly Notes on Sustainable Water Management - Q02/2014 . Natural gas is contaminating some aquifers not from hydraulic fracturing but from faulty well preparation, according to a new paper. Poorly built and cemented gas wells, rather than fracking itself, have allowed contaminants to flow into shallow drinking-water sources, according to a report published in the Proceedings of the Natural Academy of Sciences. A debate has raged for years over whether the U.S. energy boom is fouling aquifers and water wells—and what can be done about it. Researchers reported Monday that they developed a tool that can identify whether underground gas has migrated toward the surface over time, or whether it moved recently and rapidly up an industry-drilled well or the cement surrounding the well pipe. Fracking involves pushing a slurry of water, sand and chemicals down a well to break up dense rocks and coax more fuel from the ground. Many academics and ...

-- a _kt75 | note Download: Quarterly Notes on Sustainable Water Management - Q02/2014 . The most recent issue of the Quarterly Notes on Sustainable Water Management (Q02/2014) is freely available. In continuation of the successful publication of the Quarterly Notes on Sustainable Water Management the current issue concentrates on a broad range of topics including land subsidence, implications of climate change on ground water regimes, technical developments in the small hydro power sector, etc. Geographically, the Notes once more focus on regions exposed to complicated water supply conditions: Middle-East and Asia. A number of publications tackle the named issues in detail and provide cutting-edge insights on present developments. An important, because seldom considered, region represents the Horn of Africa and the water supply issues encountered there. A comprehensive overview is provided by a dedicated report. As always all reprints are completely refere...

Fracking: Should India Dive into the Shale Boom?

Image
-- a _kt75 | reprint Download: Quarterly Notes on Sustainable Water Management - Q01/2014 The energy economics of the world is now at a crossroads, giving rise to a fiery debate among experts whether it will bring about a momentous change in the world’s strategic balance. The Ukraine crisis has given an impetus to it by threatening a cut in the supply of Russian oil and gas to Europe; the West is now on the lookout for an alternative source of energy. With the United States making rapid progress in the area of shale oil and gas technology, and several large-scale shale reserves being discovered in Western Europe and Latin America, dependence on hydrocarbon supplies from the Middle East and the Persian Gulf will decrease, which will ultimately lead to a lapse in big power involvement in the region. This has all come as a boon to American companies involved in the exploitation of shale resources, and they are leaving no stone unturned in sweeping away the impediment...

OTEC: the Power of the Oceans?
China's New Wager: Pulling Energy From the Ocean

Image
-- a _kt75 | reprint Download: Quarterly Notes on Sustainable Water Management - Q01/2014 A race is under way to unlock one of the world's biggest untapped sources of clean energy—the ocean—with China emerging as an important testing ground. That could heighten competition with Western companies, especially if Chinese businesses begin using technologies developed with joint-venture partners to expand rapidly. The European Union so far has led efforts to harness the sea to make electricity, for which there are three principal techniques : underwater turbines that draw power from the ebb and flow of tides, surface-based floats that rely on wave motion and systems that exploit differences in water temperature. The world's first commercial, grid-connected tidal-flow generator was installed in Northern Ireland in 2008. Germany's Siemens AG , a big investor in wave and tidal power, predicts that tidal currents alone could someday power 250 million households world-wid...

-- a _kt75 | note Download: Quarterly Notes on Sustainable Water Management - Q01/2014 . The most recent issue of the Quarterly Notes on Sustainable Water Management (Q01/2014) is freely available. This release of the Notes comes along with a substantial diversification in terms of content. As with this issue the section 'Energy' is inserted immediately after the section 'Technology'. By this, it is intended to emphasise and consider the importance of water as an important energy carrier. Thematically, this issue concentrates on two highly sensitive issues affecting sustainable water management: the extraction of natural gas and crude oil by measn of hydraulic fracking on the one hand and the accounting of virtual water (especially with regarding to trading and agriculture) on the other hand. Both topics pose severe challenges. Whereas the former is often criticised to affect the natural water balance, in particular the mechanisms of the groun...
