Book Description
This publication outlines the relevance of turbulence on the initiation of motion of soil and explains the interaction between the load and the resistance against erosion or the strength of the bed material. The stability of stones, sand, clay and grass is discussed by using Newton's second law and a definition of the turbulence energy. Usually the equilibrium scour depth caused by jets and at piers/abutments is predicted by applying empirical relations. This publication discusses a scour approach which is based on two steps. First, a control volume that represents the scour hole is considered. Secondly, the relevant forces are determined. Newton's second law is applied, that is, the sum of forces equals zero since the scour hole is in equilibrium. This approach is discussed for different types of jet scour and scouring downstream of sills and near bridge piers and abutments.

Book Description
This Special Issue includes manuscripts about soil erosion and degradation processes and the accelerated rates due to hydrological processes and climate change. The new research included in this issue focuses on measurements, modeling, and experiments in field or laboratory conditions developed at different scales (pedon, hillslope, and catchment). This Special Issue received investigations from different parts of the world such as Ethiopia, Morocco, China, Iran, Italy, Portugal, Greece, and Spain, among others. We are happy to see that all papers presented findings characterized as unconventional, provocative, innovative, and methodologically new. We hope that the readers of the journal Water can enjoy and learn about hydrology and soil erosion using the published material, and share the results with the scientific community, policymakers, and stakeholders to continue this amazing adventure, facing plenty of issues and challenges.

Book Description
Concentrates on the application of erosion principles to erosion control, combining the perspectives of the geomorphologist and agricultural engineer. Covers mechanics and processes of soil erosion, methods of measurement and laboratory and field experimentation, approaches to erosion modelling, and implications of these to practical control. Treats water and wind erosion in depth.
