Groundwater NO3 concentration and its potential health effects in Beni Moussa perimeter (Tadla plain, Morocco)
Geoenvironmental Disasters - Tập 7 - Trang 1-11 - 2020
In this research, the concentrations of nitrates were investigated in well water sampled from the irrigated perimeter of Beni Moussa (Tadla plain, Morocco), and human health risks via ingestion and dermal pathways for individuals in different age brackets were assessed using the chronic daily intake, the dermal absorbed dose and hazard index (HI). The results showed that the groundwater NO3 conten...... hiện toàn bộ
A Potential Tsunami impact assessment of submarine landslide at Baiyun Depression in Northern South China Sea
Geoenvironmental Disasters - Tập 1 - Trang 1-11 - 2014
With mature hydrocarbon industry, Northern South China Sea (NSCS) is a hot spot for future economic development. However, the local government and researchers lack of estimations about damages brought by a submarine landslide-generated tsunami. According to oceanographic surveys, eleven landslides in different scale have been discovered in Baiyun Depression of NSCS. Hence, the need to study potent...... hiện toàn bộ
Influence of the thermal effect on quasi-static shear characteristics of calcareous soil: an experimental study
Geoenvironmental Disasters - Tập 9 - Trang 1-8 - 2022
In principle, the mechanical properties of soil particles are irreversibly changed after particles are subjected to heating. Accordingly, this study performed ring-shear tests on calcareous sand samples subjected to high temperatures to qualitatively investigate the influence exerted by the degradation of the calcareous sand, caused by the thermal effect, on the large displacement shear characteri...... hiện toàn bộ
Development of a methodology for predicting landslide hazards at a regional scale
Geoenvironmental Disasters - Tập 10 Số 1 - Trang 1-19 - 2023
Landslide risk analysis is a common geotechnical evaluation and it aims to protect life and infrastructure. In the case of sensitive clay zones, landslides can affect large areas and are difficult to predict. Here we propose a methodology to determine the landslide hazard across a large territory, and we apply our approach to the Saint-Jean-Vianney area, Quebec, Canada. The initial step consists o...... hiện toàn bộ
Morphotectonic controls on hydro-environmental hazards in rift basins: a case study from Southern Suez Canal Province, Egypt
Geoenvironmental Disasters - Tập 10 - Trang 1-28 - 2023
The Southern Suez Canal Province (SSCP) has recently encountered hydro-environmental hazards such as water logging and soil salinization, both of which impede the efficient land use planning. This study aims to assess the hydro-environmental threats to SSCP and identify the key factors that contribute to their occurrence. Previous research has demonstrated that the Gulf of Suez Rifting-related tec...... hiện toàn bộ
Report on the UNESCO Chair 2019 field school on Geoenvironmental Disaster Reduction in Shimane University, Japan
Geoenvironmental Disasters - Tập 6 - Trang 1-8 - 2019
On 14–18 March 2019, the UNESCO Chair 2019 Field School on Geoenvironmental Disaster Reduction has been held in Shimane University, Japan. The field school comprised two-day field work and three-day academic lectures. Thirty three graduate students from China, Italy, Nepal, Indonesia, France, and Japan participated, and 14 visiting professors from China, Italy, Czech Republic, Belgium, France, Rus...... hiện toàn bộ
Preliminary investigation of the 20 August 2014 debris flows triggered by a severe rainstorm in Hiroshima City, Japan
Geoenvironmental Disasters - Tập 2 - Trang 1-16 - 2015
In the early morning of 20 August 2014, a high-intensity/low-duration rainstorm occurred in Hiroshima City, in southwest Japan. Within 3 h, the rainfall exceeded 200 mm, which is more than twice the monthly-average for this area. This heavy rainfall triggered 107 debris flows and 59 shallow slides, which caused 44 injuries, and 74 deaths. 133 houses were destroyed and an additional 296 houses were...... hiện toàn bộ
Identification of the complete particle size distribution of landslide debris by the combined method of scaled image analysis, line-grid analysis and laboratory sieve analysis
Geoenvironmental Disasters - Tập 11 - Trang 1-20 - 2024
Ground failures in a slope due to gravity, are commonly known as landslides. Depend on the compositional, geological, and structural characteristics of the unstable initiation zone and the erosional composition of the propagation zone decide the complete particle size distribution of the moving mass and its gradation. This information is most important for the study of downslope movement. Only lab...... hiện toàn bộ
Consequences of Koshi flood 2008 in terms of sedimentation characteristics and agricultural practices
Geoenvironmental Disasters - Tập 4 - Trang 1-13 - 2017
Koshi flood of August 2008 in eastern lowlands of Nepal affected around 2.64 million people in India and Nepal, including 65,000 people and 700 ha fertile land in Nepal. It was calculated that 25% of the affected cultivated land of Shreepur, Haripur and western Kushaha villages in Sunsari district are still barren and remain filled with flood sediment of sizes from clay to sand even after 8 years....... hiện toàn bộ
