Erosion is the opposite of deposition, the geological process in which earthen materials are deposited, or built up, on a landform. Most erosion is performed by liquid water, wind, or ice (usually in the form of a glacier ). If the wind is dusty, or water or glacial ice is muddy, erosion is taking place. The brown color indicates that bits of ...

Carlin basin sedimentation and erosion 3 Fig. 2. Schematic map showing the possible middle Miocene paleogeography of northeast-ern Nevada using the modern physiography as a base. Overlap of some volcanic and sedimen-tary areas reflects coeval volcanism and sedi-mentation, or succession of one regime by the other. Many "highlands," which ...
Sensitive highlands areas are prone to landslides and soil erosion which then contributed to the main water pollution issues in the network of river system, sedimentation and siltation.

Erosion and sedimentation are common problemsin Peru's coastal, highland, high jungle, and low jungleregions. The highlands and high jungle are the regionswith the most serious problems due to their physiographicclimatic, and socio-economic characteristics. Mainproblems in these regions are rill, gully,and masserosion. Promising solutions are ...
The purpose of the legislation is to minimize erosion and control sedimentation to protect the water resources of the State. Any earth change/disturbance over one (1) acre in size and/or within 500 feet of a water of the state (including a lake, stream, wetland, or drain) within Oakland County requires a Soil Erosion and Sedimentation Control ...
It is also quantified that from the gross 1,075,497.6 tons/year soil erosion, 127,138.4 ton/year (11.8%) reach the Nesha watershed outlet as sediment yield. This …

Soil erosion accelerated by human activities is a critical challenge affecting soil health, agricultural productivity, food security and environmental sustainability in the highlands of Ethiopia. The aim of this study was to examine the dynamics of soil loss and sediment yield potential, and identify soil erosion hotspots using RUSLE with GIS in the …
Soil erosion has a significant impact on food security by reducing agricultural yields due to the loss of fertile soil. In this study, an integration of RUSLE …

The steeply sloping agricultural highlands in Korea have severe soil erosion. Estimation of both soil erosion and sedimentation in these highlands is necessary to make plans for soil-conservation measures, but it is not feasible using existing soil-erosion models. This study measured the site-specific concentrations of 137Cs and …
We used paleolimnological methods to reconstruct trends in sedimentation related to human-induced landscape change in 32 lakes in the intensively agricultural region of the Midwestern United States. …
Due to gully erosion, ~3.66 ha of land and ~55,198 t of soil were lost from the four identified gullies. The long-term gully erosion rate was found to be 15 t ha −1 yr −1. Large amount of sediment was trapped by the gully treatment measures and help to reduce downstream sedimentation of water bodies.
The study in Genting Highlands had been undertaken on slopes along the 20 km stretch of the leading main road from Genting SempahGenting Highlands resort (Fig. 24.3) and in the case of Fraser Hill ...
Land degradation affects over 85% of Ethiopians in the highlands population and over 40 million hectares of land (Gebreselassie et al., 2016); soil loss is estimated to reach over 852.8 million Mg ...
The Ethiopian highland reclamation study (EHRS) indicated in mid 1980's 27 million ha or almost 50% of the highland area was significantly eroded, 14 million ha seriously eroded and over 2 million ha beyond reclamation (FAO, 1986). In the Amhara region, part of the Ethiopian highland, soil erosion by water is the dominant form of erosion.
The central highlands of Ethiopia are characterized as a region of high rates of land degradation and soil erosion. This study aimed to estimate total amount of soil …
Erosion occurs when water transports sediment from one place to another. For example, a river can carry mud downstream. In general, water has more erosional power when it …
This study was conducted to attach quantitative values of soil loss and maize crop yields to on-site erosion and sedimentation indicators as perceived by the farmers in the central highlands of Kenya. Soils exhibiting splash pedestals, sheetwash, rills, sedimentation, red colour and stoniness were the erosion indicators selected for …
soil cover, soil erosion is common in the Ethiopian highlands. High-intensity rainfall occurs in most parts of Ethiopia, where cultivated land has little surface cover to reduce the
mitigate and solve the issues related to erosion and sedimentation in hilly agricultural area. Keywords: Agricultural Farming, Erosion and Sedimentation I. INTRODUCTION A highland refers to an area located at an elevation greater than 500 m above the mean sea level with slope gradients of more than 25˚ [1]. The highlands have a high potential to
Soil erosion caused by a loss of vegetation cover in highland areas is the most serious environmental problem worldwide (Gobin et al. 2004; Pimentel 2006; Borrelli et al. 2017).Rainfall intensity, soil erodibility, poor soil conservation practices, and land use land cover (LULC) change is a challenge in Ethiopia, particularly in the highlands where …
sediment deposition and differential erosion of indu-rated material[2,3]. One such location is the south-western rim of the Chryse Planitia (Fig 1), a large rem-nant impact basin, one of the lowest regions of Mars of the Pre-Noachian epoch[4].This southwestern rim has undergone subsequent sediment deposition from the
Aspects of erosion and sedimentation in the Nepalese Himalaya: highland-lowland relations. Nepal is a mountainous country, except for the nearly level lowlands in the south, representing less than 20 % of the total territory. Several irrigation schemes operate in the southern lowlands, increasing not only the extent of cultivated land, but also ...
