Special Issue Information

Dear Colleagues,

It is well known that sediment has a strong interaction with riparian vegetation on the sediment bar. Sediments are yielded through the processes of weathering, land sliding, and glacial and fluvial erosion in a catchment. Hydraulic structures such as dams, weirs, spurs, and guide banks control the floods and sediment transport into the downstream area. Seed dispersal and soil moisture as well as flushing of riparian vegetation depend on flood hydrology. The growth of riparian vegetation is affected by the substrate characteristics of the riparian zone, such as sediment size, moisture and nutrient contents, the frequency and the level of the inundation, etc., which depend on the slope of the catchment and distance from the upstream mountainous ranges.

The purpose of this Special Issue is to explore the knowledge and understanding of the events, mechanisms, reasons, factors, effects, current and future trends of the current switching mode of WHITE river to GREEN river by the flow mechanisms related to flood hydrology and sediment transport into the riparian area, as well as the effects of anthropogenic effects, such as flood control structures, discharges of nutrients, pollutants, sediments, and the alteration of the catchment area. This issue invites scientific research on different thematic areas such as laboratory scale, green house and field observations related to vegetation growth, and interacting factors and its effects on the ecosystem. Methodologically, in addition to the results of field observation, numerical modelings and long-term management perspectives of flood plain areas are also highly encouraged.

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.

The ecological dynamics of riparian areas interact with sediment transport in river systems, which plays an active role in riparian vegetation growth in the floodplain. The fluvial dynamics, hydraulics, hydro-meteorological and geomorphological characteristics of rivers are associated with sediment transport in river systems and around the riparian area. The flood disturbance, sediment with nutrients and seeds transported by river, sediment deposition, and erosion phenomena in the floodplain change the bare land area to vegetation area and vice versa. The difference in riparian vegetation area in the river floodplain is dependent on the sediment grain size distribution which is deposited in the river floodplain. Mathematical models describing vegetation growth in a short period exist in literature, but long-term modelling and validations are still lacking. In order to cover long-term vegetation growth modelling, a Dynamic Riparian Vegetation Model (DRIPVEM) was proposed. This paper highlights the existing modelling technique of DRIPVEM coupled with a Dynamic Herbaceous Model used to establish the interactive relationship of sediment grain sizes and riparian vegetation in the floodplain.
