Special Issue Information

Dear Colleagues,

At a time where matters on water demand/scarcity, flood control, land degradation and sedimentation in streams and reservoirs are becoming first-line priorities for catchment managers and stakeholders, understanding hydrological processes and sediment dynamics at the watershed scale is very relevant.

In recent years, water and sediment cycles have been subjected to stresses caused by climate change and anthropogenic pressure, eventually resulting in significant basin-wide changes.

To better understand processes and drivers of such changes, a combination of innovative techniques and tools is required nowadays, integrating modelling, remote sensing, field measurements, and experimental methods.

The goal of this Special Issue is to collect papers (original research articles and review papers) to give insights on sediment transport and morphological processes at the watershed scale, showing the potential of up-to-date methods in monitoring and modelling such phenomena.

This Special Issue welcomes manuscripts that link the following themes:

  • Watershed hydrology and sediment transport;
  • State-of-the-art methods to monitor and model morphological changes at a large scale;
  • Policies and management strategies.

We look forward to receiving your original research articles and reviews.

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. Hydrology 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 1800 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.

Humans have influenced the sediment transport of rivers on a centurial scale. Our goal was to use the rate of lateral channel processes as a proxy to reconstruct sediment budget (SB) changes of a lowland river (Middle Tisza, Hungary) on a historical scale (1838–2017). The gross sediment budget (GSB) refers to the total area of eroded and accumulated surfaces, and the net sediment budget (NSB) indicates the sediment sink or source characteristics. At the beginning (1838–1890), the artificial cut-offs increased the slope and channel erosion, but the eroded sediment deposited in the oxbows, so the reach acted as a sediment sink (NSB: +0.1–0.8 m2/m/y). Then (1890–1929), a quasi-equilibrium state developed (NSB: −0.2 m2/m/y to +0.4 m2/m/y). Later (1929–1976), the bank protections impeded lateral erosion, so the system became a sediment sink again (NSB: +0.1–0.7 m2/m/y). Finally (1976–2017), the erosional processes accelerated due to dam construction and revetment collapses, and now the river is a sediment source (NSB: −0.03 to −0.08 m2/m/y). This study proved that (1) the actual SB could not be projected in the long term, as it was heavily modified, and (2) lateral channel changes could be used as a proxy to estimate long-term SB.
