Soil erosion assessment
-
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.

This article presents the results of applying geospatial technology to assess soil erosion for Yen Chau district. Geospatial Technology was applied to build maps of factors affecting soil erosion such as: rain erosion coefficient map (R), soil erosion resistance coefficient map (K), terrain erosion coefficient map (LS), cover erosion coefficient map (C) and farming practices (P). Improved universal soil loss equation (RUSLE) due to Wischmeier and Smith was used to create soil erosion maps.

This paper simulated the sediment load in different periods, including the period without influences of the reservoir, and the period after Hoa Binh, Thac Ba, and new reservoirs were constructed. Since then illustrated an overall view of the erosion, sediment transport in the lower Red River, and of aplliedusability the model to research for other river systems.

Land degradation has been identified as one of the most serious problems that threaten the sustainability of agriculture. In an effort to address these problems, Soil and Water Conservation (SWC) measures are considered key to addressing the problems of low agricultural productivity and soil degradation in India as well as world. Impact assessment has gained more attention due to the increased need to demonstrate the outcomes of any NRM interventions, development projects and programs.

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.

A detailed land resources inventory (LRI) of Amarapura-2 micro watershed was carried out at 1:8000 scale for deriving land capability and crop suitability classes. The micro watershed is located between 770 8’ to 170 17’ North latitude and 770 101 to 170 151 East longitude of Lingasaguru taluk, Raichur district, Karnataka State, India. Twenty four soil phase units with eight soil series were identified through detailed soil resource study. Land capability subclasses in the study area were IIIes and IVes with limitations of soil erosion, texture, soil drainage, soil fertility and topography.

The Aravalli region in India is very prone to soil erosion and low hydrological regimes. The present study has been carried out in the Aravalli hill slopes to characterized land resources, identified soil problems to establish appropriate soil conservation measures in risk prone areas and appropriate land management practices. The integrated remote sensing (IRS-P6-LISS-IV and cartosat-1 merged data) and GIS based methodologies were employed for terrain analysis, identification of slope, landform, land use/land cover classes, hydro-geomorphology.

Soil erosion is the common land degradation problem in the worldwide, and also is one of the most critical environmental hazards of recent times, which reduces productivity. Assessment of soil erosion is expensive and intensively long exercise. In the present study an USLE model has been used for estimation of soil loss for Raigad district of Konkan region of Maharashtra.

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.

In recent decades, unsustainable use of resources and the implementation of dams upstream accompanied with sea level rise acceleration has led to an extreme mangrove depletion, increase of coastal vulnerability in the Mekong delta. Extensive shrimp culture, where mangrove forest have been turned into aquaculture ponds are adding to the problem. The aim was to assess the current situation and find solutions which go in hand with the Building with Nature (BwN) concept for two selected locations along the Vinh Chau coast.

We conducted 20 plots & 80 random points to collect data. To assess soil erosion, the study was based on IDW interpolation in ArcGIS to conduct maps. The results show that (1) There are five main forest types (Pine, mixed Pine and Acacia, Acacia, Eucalypt, mixed Eucalypt & Acacia) in which Pine (Pinus merkusii) is a native species and dominant in protection plantations with 47.65% (665.96 ha).

The main objective of this study was to determine the soil erosion risk in Gölbafli Environmental Protection Area and its vicinity using the CORINE model. The model consists of 6 steps, each of which using different overlaying combinations of soil texture, depth, stoniness, climatic data, land use and land cover information.

In this research, the applicability of geographic information system (GIS) and remote sensing (RS) techniques was tested to assess soil erosion risk with the ICONA erosion model. This study was carried out in the Ankara-Beypazari area because of its variety of diverse landforms, land uses and land covers.

The main objective of this study is to assess and simulate impacts of climate change on erosion and water flow in the basin. Using a GIS database and Soil and Water Assessment Tool (SWAT) model, the water flow and soil loss were assessed with data in period 1980-1999 called the based period, then simulated until 2100 considering the medium emission scenario (B2).
