Modeling soil erosion

The paper "A novel approach of neural networks and USLE in smart soil erosion modeling, case study in Southern coastal of Viet Nam" adopted one of the neural networks - the Long ShortTerm Memory (LSTM) to analyze temporal variations in erosion patterns over time, aiding in understanding erosion dynamics. Furthermore, another common soil erosion model - the Universal Soil Loss Equation (USLE) was investigated to predict annual soil loss. Our data were extracted from remotely sensed data (DEM - Digital Elevation Model and MODIS) and vector data of the study area.

Erosion is an environmental phenomenon, but due to human activities this phenomenon has led to many serious problems. With the aim of protecting soil resource, as well as circumscribe damages by erosion, so the study of applying USLE on assessing soil erosion at Lam Son headwater catchment was conducted. To reach the purposes, the content of the study focus on collecting data and using USLE, ArcGis software to form rainfall map, slope coefficient and slope length map, canopy cover coefficient map.

Suffusion is one of the four types of internal erosion and accounts for 46% of erosion phenomena in earth dams. Suffusion is an erosion of fine particles inside the soil structure that move out of the voids between coarse particles caused by permeability flow. Identification of internal erosion is necessary to mitigate the loss of humans and property as underground erosion occurs.

Soil erosion is a naturally occurring process in mountainous areas that affects all landforms. Located in Central of Vietnam, in the tropical monsoon climate Da Nang City is characterized by more than 70 percentage of area with hilly and mountainous topography. This study is objective apply the Universal Soil Loss Equation (ULSE) model developed by Wischmeier and Smith (1978) integrating with remote sensing data and Geographical Information System (GIS) tool to evaluate soil erosion risk in Da Nang City, Vietnam.

Soil erosion depletes the productive layer of soil which is an ultimate resource for all agricultural activities. Since erosion rate varies with watershed characteristics, a study of soil and water dynamics at a watershed level can facilitate a scientific approach toward their conservation and management. The study involves obtaining peak runoff and input parameters (K,LS,C & P) of Modified Universal Soil Loss Equation (MUSLE) integrating GIS platform to estimate soil loss...

Soil erosion strongly affects crop yield, undermines the long term productivity of farm land and sustainability of farming system, and poses a major threat to the livelihood of the farmers and rural communities. The United Nations Environmental Program reported that the productivity of soil has reduced and resulting in economically unfeasible cultivation on about 20 million hectare of land each year due to soil erosion and resulting degradation of land.

In the Eastern Europe and Central Asia region, the low-input cropping systems dominated by cereal monoculture and intensive tillage have a marked negative impact on pressure from diseases, weeds and pests resulting in decreased profit margins. The agricultural model based on mechanical soil tillage, exposed soils and continued monocropping is typically accompanied by negative effects on agriculture’s natural resource base to such an extent that future agricultural productive potential is jeopardized.

Runoff estimation is a key factor in the design of soil and water conservation structures to prevent land degradation and erosion. In the present study, the Soil and Water Assessment Tool (SWAT) model was used to estimate the runoff in Pindwara watershed situated in the Sirohi district of Rajasthan and spanning over an area of about 1428 km2 . Temporal weather data of rainfall and temperature, digital elevation models, soil data, land use land cover imagery was provided to the model as input to estimate runoff at the watershed outlet.
