Research ArticleOpen accessEvery word in the titleMonitoring the Rate of Change at Urualla Gully Erosion Site Using GIS and Remote Sensing MethodologySylvanus IroUrualla gully erosion was monitored using GIS and remote sensing in Urualla, Ideato North Imo State Nigeria. The objective is to calculate the rate of change of Urualla gully erosion and identify measures to control its growth. The study's data came from primary and secondary sources, such as Google Earth imageries, DEMs, and in situ measurements. Google Earth was used … …American Journal of Environmental Sciences, Vol. 19, Issue 5 · 28 Feb 2024 · 5,314 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDetermining Causes of Gully Erosion and Associated Rates of Change in South-East Nigeria, using a Remote Sensing and GIS MethodologySylvanus IroThe study of gully development on a regional scale is currently threatened by the intrinsic costs associated with steady field tracking and monitoring and the lack of historic measurements to perform time series analysis. The research objective is to develop a low-cost GIS and Remote Sensing methodology for monitoring and quantifying gully erosion and development over time, identifying the impact … …American Journal of Environmental Sciences, Vol. 16, Issue 5 · 22 Oct 2020 · 7,431 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDeep Erosion by Continental Ice Sheets: A Northern Missouri River Drainage Basin Perspective: North AmericaEric ClausenWhile accepting some erosion by continental ice sheets most geologists reject a previously proposed deep erosion by continental ice sheets hypothesis, yet common sense logic suggests continental ice sheets should have eroded much more than they are usually given credit for. Such situations arise in scientific communities when an accepted paradigm cannot adequately explain significant observable evidence. A new and … …Current Research in Geoscience, Vol. 8, Issue 1 · 18 Jan 2019 · 8,883 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGully Erosion Rate Assessment at the Choqazanbil Temple Using GIS MethodsHadi JarahiThe Choqazanbil temple located at 60 km of south west of shush city in the south west of Iran. This temple with 3500 years archaism is one of the oldest historical titles in Iran. The temple position is close to the Sardarabad anticline with Neogene to Quaternary deposits. Many news about damaging of ancient buildings are reported most recently. This … …Current Research in Geoscience, Vol. 7, Issue 2 · 6 Nov 2017 · 7,565 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleContribution of Remote Sensing in the Estimation of the Populations Living in Areas with Risk of Gully Erosion in Kinshasa (D.R. Congo). Case of Selembao TownshipKayembe wa Kayembe Matthieu, Ngoy Ndombe Alain, Makanzu Imwangana Fils et al.This paper proposes a methodology combining very high spatial resolution satellite image, GIS and field surveys to estimate the number of people living in areas at (high) risk of landslides or gully erosion in Selembao (Kinshasa). It also gives their socio-economic characteristics. Results show that 185,000 out of the 314,699 inhabitants estimated in Selembao (58.3% of the population) live in … …Current Research in Geoscience, Vol. 6, Issue 1 · 6 Jun 2016 · 8,612 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIdentification of Erosion Hotspot Area using GIS and MCE Technique for Koga Watershed in the Upper Blue Nile Basin, EthiopiaTewodros T. Assefa, Manoj K. Jha, Seifu A Tilahun et al.Soil erosion is a serious threat in Ethiopian highlands. Continuous land degradation resulted in loss of fertile top soil leading to low agricultural productivity. In addition, excessive soil erosion from Koga Watershed in upper catchment to an artificial reservoir (Koga Dam reservoir) is substantially reducing its service life. Community participatory based effective watershed management strategies may have tremendous potential to … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 10 Sep 2015 · 9,147 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAssessment of the Cenozoic Erosion Amount Using Monte Carlo Type-Petroleum Systems Modeling of the Hammerfest Basin, Western Barents SeaKrzysztof Jan Zieba, Matthias Daszinnies, Benjamin Emmel et al.The Cenozoic uplift and erosion is often believed to be a major risk factor in hydrocarbon exploration in the Barents Sea causing petroleum redistribution and leakage from filled traps. Therefore, the estimation of erosion amount is an important but often underrepresented task in the basin modeling procedure. The assessment of erosion magnitudes and spatial distribution by geochemical and thermo chronological … …Current Research in Geoscience, Vol. 4, Issue 2 · 29 Apr 2015 · 8,318 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBed-Load Sediment Profile and Effect of River Bank Erosion on River Cross-SectionMohd Ekhwan Toriman, Frankie Marcus Ata, Mohd Khairul Amri Kamarudin, Mushrifah IdrisThe processes of lateral and riverbank erosion are among the elements of river morphology dynamic resulting from natural processes and human activities. This process has been studied in detail throughout the research for four months starting from 7 October 2009 to 26 January 2010. In this research, technique of erosion pins were applied at five plots selected along the Chini … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 28 Aug 2013 · 7,337 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUtilizing Geographic Information System for Prediction of Soil Erosion in Sono Sragen Catchment AreaMuhammad Mukhlisin, SukocoProblem statement: Embung is a small dam created by manmade lakes and used to catch water during rainy season for an irrigation source. In Sragen area, Embung Sono is one of around twenty embung that used to catch rain water for irrigation. Soil erosions in catchment area are potential to reduce water capacity of the embung. Although many embung have … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 13 Jul 2011 · 7,795 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Simplified Analytical Modeling of the Hole Erosion TestMohammed Bezzazi, Abdellatif Khamlichi, Miguel Prron Vera et al.Problem statement: Internal erosion occurs in soils containing fine particles under the action of high pressure gradients that could result from water discharge. This phenomenon can yield in its final stage to the formation of piping which constitutes a real threat for hydraulics infrastructures as it can precipitate their entire rupture in very short time. In order to mitigate this … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 30 Nov 2010 · 8,025 accessesView PDFCite
