Longitudinal and transverse dispersion coefficients in braided rivers

by IWA Publishing  (Jul. 23, 2014)

The dispersion characteristics of braided rivers are presently unclear. The comprehensive flow structure in a physical braided river model was measured and was used to estimate its dispersion coefficient tensor. The largest values of the longitudinal and transverse dispersion coefficients occurred in the separation zone in two anabranches. The ...

Modelling of point and diffuse pollution: application of the Moneris model in the Ipojuca river basin, Pernambuco State, Brazil

by IWA Publishing  (Jul. 19, 2013)

Emissions of pollutants and nutrients are causing several problems in aquatic ecosystems, and in general an excess of nutrients, specifically nitrogen and phosphorus, is responsible for the eutrophication process in water bodies. In most developed countries, more attention is given to diffuse pollution because problems with point pollution have ...

Removal of indigenous coliphages and enteric viruses during riverbank filtration from highly polluted river water in Delhi (India)

by IWA Publishing  (Jun. 18, 2014)

Emerging countries frequently afflicted by waterborne diseases require safe and cost-efficient production of drinking water, a task that is becoming more challenging as many rivers carry a high degree of pollution. A study was conducted on the banks of the Yamuna River, Delhi, India, to ascertain if riverbank filtration (RBF) can significantly ...

Polybrominated diphenyl ethers, dechlorane plus, and polychlorinated biphenyls in tree bark near the upper Yellow River, China

by John Wiley & Sons, Ltd.  (Apr. 25, 2014)

Willow tree bark samples from urban and rural sites in Inner Mongolia, Ningxia Province, and Gansu Province, in the Yellow River basin, were analyzed for polybrominated diphenyl ethers (PBDEs), dechlorane plus (DP), and dioxin‐like polychlorinated biphenyls (DL‐PCBs) to compare their relative levels in air in these areas (i.e., treating bark as ...

Land use patterns and organic pollution in the rivers

by Inderscience Publishers  (Jun. 28, 2011)

The riverine system is an important resource of water supply to the communities but rivers are being contaminated due to organic pollutants, which is a serious problem. Organic contamination has been discussed with regard to the different rivers of the world. Various organic pollutants, detected in water and the sediment of the rivers, have been ...

Nonbinding agreements in Europe's trans–boundary river pollution: a first assessment

by Inderscience Publishers  (Dec. 2, 2013)

Deciding whether commitments should involve binding or nonbinding agreements is a crucial strategic element when it comes to designing effective governance systems. Up to now, legally binding treaties seem to be the preferred approach. More than 1500 bilateral and 1100 multilateral treaties have been signed according to one recent compilation. ...

Water Pollution

by IWA Publishing  (Jul. 25, 2012)

Water pollution is a major global problem that requires ongoing evaluation and revision of water resource policy at all levels (from international down to individual aquifers and wells). It has been suggested that it is the leading worldwide cause of deaths and diseases, and that it accounts for the deaths of more than 14,000 people daily. In ...

River basin planning: Principles, procedures and approaches for strategic basin planning

by IWA Publishing  (Mar. 10, 2014)

Water provides the lifeblood of natural systems, societies and economies. People have lived near and on rivers, lakes, wetlands and deltas for many centuries. Rivers provide a multitude of services such as water supply, waste assimilation, fisheries, energy production, flood attenuation, spiritual, cultural and recreational benefits, and the ...

Modelling Escherichia coli dynamics in the river Zenne (Belgium) using an OpenMI based integrated model

by IWA Publishing  (Mar. 26, 2014)

In 2000, the European Union (EU) launched the Water Framework Directive (WFD), calling for a good ecological status for water bodies by 2015 through integrated river basin management. Despite huge investments, the river Zenne (Belgium) still acquires high loads of pollutants. A multidisciplinary research project was therefore launched to evaluate ...
