Special Issue Information

Dear Colleagues,

Baseflows are important for ecosystem health, water quality and conveyancing urban water during dry periods. Because they form a small fraction of the mean annual flow in streams, adverse impacts on this flow component can be easily dismissed. Baseflows are modified by management of surface and groundwater, changes in land use and climate variability and change. They are not easily measured nor modelled at relevant spatial and temporal scales; connectivity of flow within streams and between streams and groundwater can be complex; and the interaction between the ecosystems and this component of the flow regime needs to be better understood.

The aim of this special issue is to provide a focus on the need for a cross-disciplinary understanding of baseflows in order to better manage them for river health.

This edition encourages papers, including case studies, across a range of disciplines (hydrogeology, hydrology, ecology, hydrochemistry) that improve characterisation of hydrological and ecological processes associated with low stream flows; assessment and modelling of low flows and riparian processes; assessment and management of risks associated with low flows; and determination of water management requirements of baseflow component of the flow regime for multiple users of streams. Papers may be of a single discipline, but needs to relate to other disciplines and be relevant to management of baseflows.

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 submissions that pass pre-check are 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 semimonthly 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 2600 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.

Of all the environmental elements that influence the biological communities of rivers, water flow characteristics are undoubtedly the most important. Unfortunately, natural hydrological characteristics are increasingly threatened by human activities, especially in alpine or high mountain areas where there are numerous hydropower plants. In this study, we analysed the impact of hydrological alterations on the macroinvertebrate community of a lowland river in NW Italy. Specifically, we analysed the macroinvertebrate communities of an unaffected site by comparing them with those of a site subject to hydrological alteration. We adopted an approach that is not only taxonomic but also functional, allowing us to study a component of biodiversity that is generally less known. Our results show that the flow-altered site hosted a benthic community with lower species and functional diversity than the control site. Interestingly, we also detected a number of significant differences between the summer and autumn samples. In particular, examination of community-weighted mean (CWM) trait values reveals significant variation in body size, voltinism, substrate, locomotion, feeding habits and other traits between sites and seasons. The integration of taxonomic and functional approaches provides a comprehensive understanding of how human-induced hydrological variations can affect aquatic biodiversity and ecological functions.
