Quantification of Soil Erosion and Sediment Transport in Basins

Dear Colleagues,

Soil erosion in basins is mainly caused by rainfall and runoff. Soil erosion products are transported by runoff into the streams of the basin considered and through the streams to the basin outlet, which may also be the inlet of a natural or artificial lake. The quantification of the physical processes of soil erosion and sediment transport can be achieved by mathematical modeling including empirical, conceptual and physically based relationships. Field measurements, laboratory experiments, and satellite monitoring can be used for the verification of computational results. In recent years, quantification of stream sediment transport has been implemented by means of machine learning methods. Additionally, the uncertainty resulting from parameters included in sediment transport equations is visualized by fuzzy logic analysis. Intense and frequent rainfalls on basins have catastrophic consequences for both rural and urban settlements, namely the transport of large amounts of suspended sediment in the streams, mud floods, the removal of fertile soil, and the acceleration of reservoir sedimentation. The final aim of the computations mentioned above is the dimensioning of structures against soil erosion and stream sediment transport, e.g., check dams and retention basins. Management measures such as land use change and contour tilling can reduce soil erosion effects on cultivated land.

List of topics:

• Mathematical modeling of soil erosion in basins due to rainfall and runoff;
• Mathematical modeling of stream sediment transport;
• Verification of computational results by means of field measurements;
• Verification of computational results by means of laboratory measurements;
• Application of machine learning methods to sediment transport problems;
• Application of fuzzy regression analysis to sediment transport formulas;
• Constructive and management measures against soil erosion and sediment transport.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Land 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 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.
