Removal of plant pathogenic bacteria during agricultural managed aquifer recharge to produce irrigation water and protect plant health

Eisfeld, R.C.M. (author)

Fresh water is an essential resource for life. Yet, overexploitation of water resources, rainfall shortages, and a decrease in water quality by pollution increase water scarcity worldwide. Since agricultural production consumes about 70% of the available fresh water resources, it is particularly vulnerable for water scarcity. Therefore, this...

Integrating the flow regime and water quality effects into a niche-based metacommunity dynamics model for river ecosystems

Wang, Yibo (author), Liu, Pan (author), Solomatine, D.P. (author), Li, Liping (author), Wu, Chen (author), Han, Dongyang (author), Zhang, Xiaojing (author), Yang, Zhikai (author), Yang, Sheng (author)

Aquatic community dynamics are closely dominated by flow regime and water quality conditions, which are increasingly threatened by dam regulation, water diversion, and nutrition pollution. However, further understanding of the ecological impacts of flow regime and water quality conditions on aquatic multi-population dynamics has rarely been...

Comparison of dredging, lanthanum-modified bentonite, aluminium-modified zeolite, and FeCl₂ in controlling internal nutrient loading

Kang, Li (author), Haasler, Sina (author), Mucci, Maíra (author), Korving, Leon (author), Dugulan, A.I. (author), Prot, T.J.F. (author), Waajen, Guido (author), Lürling, Miquel (author)

The eutrophic Bouvigne pond (Breda, The Netherlands) regularly suffers from cyanobacterial blooms. To improve the water quality, the external nutrient loading and the nutrient release from the pond sediment have to be reduced. An enclosure experiment was performed in the pond between March 9 and July 29, 2020 to compare the efficiency of...

Biogeochemical networks in the abandoned historical gold mines affecting mobilization and transport of arsenic in Kolar

Ghosh, D. (author), Kavil, Sarath Pullyottum (author), Arya, Prakash C. (author), Das, Bhaskar (author)

Enormous water-logging in ancient abandoned mining shafts of Kolar Gold Fields (KGFs), has largely induced the leaching of sulfide-rich gold minerals contaminating the aquifer system with hazardous elements. Transport of these contaminant has posed threat to the health of the urban population of Kolar township. A detailed survey of borewells,...

Suitability indices for assessing functional quality of urban surface water

van der Meulen, E. S. (author), van Oel, P. R. (author), Rijnaarts, H. H.M. (author), Sutton, N. B. (author), van de Ven, F.H.M. (author)

Urban surface waters are used in many different ways. With increasing demand for human use functions, improved insight is required into the functional quality of these waters. A method to assess this functional quality in a systematic way and for a wide variety of use functions is not available. We propose to use suitability indices (SIs) for...

Thermal Energy Recovery from Drinking Water Systems: Assessing Water Quality and Downstream Temperature Effects

Moerman, Andreas (author), van Bel, Nikki (author), Oesterholt, Frank (author), de Laat, Vincent (author), Blokker, E.J.M. (author)

Climate change demands for sustainable options for heating and cooling of buildings. Low-temperature thermal energy can be abstracted from the drinking water distribution system (DWDS); this is called thermal energy from drinking water (TED). The possible use of TED as a secondary function of the DWDS raises the question whether this...

Stability of a Class of Controllers for a Sequence of Canals and Structures

van Nooijen, R.R.P. (author), Kolechkina, A.G. (author)

Networks of open channels form an important category of environmental systems. They are used not only to transport irrigation and drainage water, but also as highways for barges transporting raw materials and goods. Automatic control of these systems poses specific problems. A local stability analysis for an open canal that is split into...

COVID-19: Research Directions for Non-Clinical Aerosol-Generating Facilities in the Built Environment

Law, Roger C. K. (author), Lai, Joseph H.K. (author), Edwards, David John (author), Hou, H. (author)

Physical contact and respiratory droplet transmission have been widely regarded as the main routes of COVID-19 infection. However, mounting evidence has unveiled the risk of aerosol transmission of the virus. Whereas caution has been taken to avoid this risk in association with clinical facilities, facilities such as spa pools and Jacuzzis,...

Streams, sewage, and shallow groundwater: stream-aquifer interactions in the Kathmandu Valley, Nepal

Prajapati, Rajaram (author), Overkamp, Nick N. (author), Moesker, Niek (author), Happee, K. (author), van Bentem, R. (author), Danegulu, Anusha (author), Manandhar, Bikesh (author), Thapa, Amber Bahadur (author), Davids, J.C. (author)

The Kathmandu Valley in Nepal is facing a water quantity and quality crisis due to rapid urbanization and haphazard water and wastewater planning and management. Annually, groundwater extractions in the Kathmandu Valley exceed capture, resulting in groundwater table declines. Streams are often important sources of recharge to (or destination...

Is a simple model based on two mixing reservoirs able to reproduce the intra-annual dynamics of DOC and NO₃ stream concentrations in an agricultural headwater catchment?

Strohmenger, L. (author), Fovet, O. (author), Hrachowitz, M. (author), Salmon-Monviola, J. (author), Gascuel-Odoux, C. (author)

Agriculture disturbs the biogeochemical cycles of major elements, which alters the elemental stoichiometry of surface stream waters, with potential impacts on their ecosystems. However, models of catchment hydrology and water quality remain relatively disconnected, even though the observation that dissolved organic carbon (DOC) and nitrate ...

The impact of scrubber discharge on the water quality in estuaries and ports

Teuchies, Johannes (author), Cox, Tom J.S. (author), Van Itterbeeck, Katrien (author), Meysman, F.J.R. (author), Blust, Ronny (author)

Background: The International Maritime Organization (IMO) has set limits on sulphur content in fuels for marine transport. However, vessels continue to use these residual high-sulphur fuels in combination with exhaust gas cleaning systems (EGCS or scrubbers). Next to high sulphur, combustion of these fuels also results in higher emissions of...
