Gully erosion is one of the most complicated and destructive forms of water erosion. In order to prevent this erosion, the important factors advancing gully head must be recognized. Nowadays, several models have been proposed in measuring gully head advancement and identifying the severity of erosion. These models must be calibrated for each country to see whether they are applicable or not. So...

This document describes a simple distributed index system to be used by a Locator/ID Separation Protocol (LISP) Ingress Tunnel Router (ITR) or Map-Resolver (MR) to find the Egress Tunnel Router (ETR) that holds the mapping information for a particular Endpoint Identifier (EID). The MR can then query that ETR to obtain the actual mapping information, which consists of a list of Routing Locators ...

Gully erosion is known to affect soil productivity, and limit land use in many parts of the world. To assess susceptibility soils gully erosion, triggering factors must be analyzed. A simulation development over time was implemented Python – GIS modules based on topographic characteristics study area, properties, measured runoff. The results show that developed allow a successful data preparati...

Gullies are landforms with specific patterns of shape, topography, hydrology, vegetation, and soil characteristics. Remote sensing products (TanDEM-X, Sentinel-1, Sentinel-2) serve as inputs into an iterative algorithm, initialized using a micro-mapping simulation training data, to map gullies in the northwestern Namibia. A Random Forest Classifier examines pixels similar characteristics pool u...

The Three Gorges Reservoir Area is one of the most severe soil erosion in China. Serious erosion has degraded the soil productivity, deteriorated the ecological environment, and influenced the service life of Three Gorges Reservoir. The natural and social-economic factors which influence the soil erosion in Three Gorges Reservoir Area include topography, geological situation, vegetation, rainfa...

Oyster reefs provide valuable ecosystem services that contribute to coastal resilience. Unfortunately, many reefs have been degraded or removed completely, and there are increased efforts to restore oysters in many coastal areas. In particular, much attention has recently been given to the restoration of shellfish reefs along eroding shorelines to reduce erosion. Such fringing reef approaches, ...

In Brazil, the development of gullies constitutes widespread land degradation, especially in state South Mato Grosso, where fighting against this degradation has become a priority for policy makers. However, environmental and anthropogenic factors that promote gully are multiple, interact, present complexity can vary by locality, making their prediction difficult. framework, database was constr...

Gully erosion has been identified in recent decades as a global threat to people and property. This problem also affects the socioeconomic stability of societies therefore limits their sustainable development, it impacts nonrenewable resource on human scale, namely, soil. The focus this study is evaluate prediction performance four machine learning (ML) models: Logistic Regression (LR), classif...
