Mechanism and Simulation of Water Erosion and Nutrient Loss on Hillslopes

Dear Colleagues,

Soil erosion is a global issue, and severe soil erosion leads to the loss of nutrients such as nitrogen, phosphorus, and potassium from the soil, resulting in a decline in soil fertility, reduction in soil quality, and increased agricultural non-point source pollution of water environments. Moreover, surface soil erosion alters soil texture and accelerates desertification in arid regions. Therefore, nutrient loss through soil erosion is not only an agricultural problem, but also an ecological and environmental concern. Soil nutrient loss on hillslopes is a complex physical–chemical process influenced by various factors, including rainfall characteristics, soil properties, land surface conditions, and the properties of involved chemical substances. To effectively predict and control the migration of soil nutrients in tandem with surface runoff, it is necessary to analyze and study this complex process.

This Special Issue, titled “Mechanism and Simulation of Water Erosion and Nutrient Loss on Hillslopes”, aims to provide an overview of studies that assess various nutrient loss processes using qualitative and quantitative approaches. Potential areas of interest include, but are not limited to, topics such as numerical simulations, conceptual models, experimental studies, and future predictions of nutrient loss on hillslopes.

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. 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.
