Special Issue Information

Dear Colleagues,

For a sustainable environment and food production, under the increasing pressures of a growing population and changing climate, we need efficient ways to manage nutrients and other contaminants and mitigate their losses to water in agricultural landscapes. To meet this challenge, we need a comprehensive understanding of how hydrological and chemical controls influence the contaminants along the transfer continuum, both over time and space, and in different catchment typologies, while also considering the role of climatic drivers and catchment residence time. This Special Issue welcomes contributions from observational and modelling studies that advance this knowledge and help reshape the thinking of future river catchment management.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Sources and Mechanisms of Low-Flow River Phosphorus Elevations: A Repeated Synoptic Survey Approach
Water 2019, 11(7), 1497; https://doi.org/10.3390/w11071497 - 18 Jul 2019
Abstract
High-resolution water quality monitoring indicates recurring elevation of stream phosphorus concentrations during low-flow periods. These increased concentrations may exceed Water Framework Directive (WFD) environmental quality standards during ecologically sensitive periods.

High-resolution water quality monitoring indicates recurring elevation of stream phosphorus concentrations during low-flow periods. These increased concentrations may exceed Water Framework Directive (WFD) environmental quality standards during ecologically sensitive periods. The objective of this research was to identify source, mobilization, and pathway factors controlling in-stream total reactive phosphorus (TRP) concentrations during low-flow periods. Synoptic surveys were conducted in three agricultural catchments during spring, summer, and autumn. Up to 50 water samples were obtained across each watercourse per sampling round. Samples were analysed for TRP and total phosphorus (TP), along with supplementary parameters (temperature, conductivity, dissolved oxygen, and oxidation reduction potential). Bed sediment was analysed at a subset of locations for Mehlich P, Al, Ca, and Fe. The greatest percentages of water sampling points exceeding WFD threshold of 0.035 mg L−1 TRP occurred during summer (57%, 11%, and 71% for well-drained, well-drained arable, and poorly drained grassland catchments, respectively). These percentages declined during autumn but did not return to spring concentrations, as winter flushing had not yet occurred. Different controls were elucidated for each catchment: diffuse transport through groundwater and lack of dilution in the well-drained grassland, in-stream mobilization in the well-drained arable, and a combination of point sources and cumulative loading in the poorly drained grassland. Diversity in controlling factors necessitates investigative protocols beyond low-spatial and temporal resolution water sampling and must incorporate both repeated survey and complementary understanding of sediment chemistry and anthropogenic phosphorus sources. Despite similarities in elevation of P at low-flow, catchments will require custom solutions depending on their typology, and both legislative deadlines and target baselines standards must acknowledge these inherent differences.

Diffuse water pollution from agriculture (DWPA) is a major environmental issue worldwide causing eutrophication, human health problems, increased water treatment costs and reducing the recreational potential of water bodies. In addition to penalties and provision of incentives, policy efforts are increasingly focusing on raising land managers’ awareness regarding diffuse pollution under the expectation that this would influence behaviours and thus increase uptake of best management practices that would, in turn, improve water quality. Given the multimillion financial investments in these awareness-focused approaches, a good understanding of the awareness–behavioural change–water quality pathway is critical to set the basis for assessing the real potential of these policy interventions. We systematically review the evidence across the full pathway drawing on published peer-reviewed papers from both the social and natural sciences, with a focus on Europe and North America. Results indicate that there is no one study that looks at the pathway in full, evidencing the paucity of research on the topic. For the limited studies that focus on the different components of the pathway, we find mixed evidence for the relationship between awareness and behaviour, and behavioural change and water quality. Furthermore, complexity within the pathway (e.g., through the study of factors mediating and moderating such relationships) has hardly been addressed by the literature. An in-depth understanding and analysis of this complexity—through an integrative model covering the entire pathway—could help in the design and implementation of effective policy strategies to encourage best land management practices and ultimately improve water quality.

Effect of Operational Conditions on Nitrogen Removal from Polluted Stream in A Combined Natural Wastewater Treatment System

Bilal Tunçsiper, University of Nigde Omer Halisdemir, Engineering Faculty, Environmental Engineering Department, 51240 Nigde, TURKEY

The contents of the article: This study proposes a new combined natural wastewater treatment (NWT) system where settlement basin and overland flow system were used beside constructed wetland system along with filtering materials, which contributes to existing knowledge. The system was designed to improve the water quality of an over-polluted creek that functions as a wastewater channels. In general, this system provided efficient results for controlling water pollution in over-polluted streams.

Riparian Buffer Zone Efficiency: Quantifying Nutrient Retention in Wetlands of a Warm Temperate Climate Setting

Dominik Henrik Zak

Abstract: Riparian buffer zones are sections of natural or restored wetland forming a transition between land and aquatic environments, which can uptake agricultural pollutants such as nitrogen and phosphorus. These nutrients have the potential to accumulate in standing water bodies from lakes to the closed Baltic Sea, causing eutrophication and subsequent ecological degradation. This review attempts to quantify the nutrient input (load), nutrient output (loss) and nutrient removal and/or retention from multiple studies of various types of wetlands situated within the warm, temperate climatic region common to northern Central Europe located for example in Denmark, Germany, The Netherlands and Poland.
