Reporting a Case Study on Computational Fluid Dynamics (CFD) Modelling to Estimate Fluvial Bank Erosion

Models of river bank erosion are an important prerequisite for understanding the creation of river meanders and for estimating the possible loss of land and the potential risk to infrastructure in the floodplain. While bank erosion models considering large-scale mass collapse have been established, the contribution of fluvial erosion (the particle-by-particle erosion mechanism due to…

A Study on the Caucasus Region: Crop Model Based on “Slow” Climate Change over the Last 60 Years

The analysis is based on instrumental data (temperature and rainfall) from 20 weather stations located between 1961 and 2018 on the territory of the Caucasian region. Mathematical statistics approaches, trend analysis and the rescaled range approach have been used. The warming trend was found to have occurred in all climate zones, accelerated since the beginning…

Critical Evaluation and Estimation of Shear Wave Structure and Horizontal to Vertical Spectral Ratio at Different Sites in Kathmandu Valley

The present study was conducted to determine the resonant frequency of the soil and to classify the subsurface soil based on the structure of the shear wave velocity. Five sites have been chosen for this reason, such as Pulchowk, Chhauni, Gaushala, Buddhanagar and Bhainsepati. Approximately 20 data were collected at each location, and then the…

Suitability of Fibre Reinforced Polymer Confined Concrete In-Filled Steel Tube Columns in Vulnerable Zones of Instability: A Case Study from Bhuj Earthquake Epicentral Zone, Gujarat, India

The present study aims to evaluate the suitability of infilled steel tube columns of fibre reinforced polymer confined concrete in vulnerable areas of instability in the basement of the Bhuj Earthquake Epicentral Zone, Gujarat , India. In order to understand the sub-surface structural characteristics of a sedimentary basin, basement mapping is necessary, which in turn…

Examining the Potential Impacts to Wetlands and Water Bodies Due to Mineral Exploration, Pebble Copper-Gold Prospect, Southwest Alaska

The majority of mining ventures do not make it past the stage of discovery. There is, however, no detail in the literature on the impacts on natural waters of mineral exploration drilling. A copper-goldmolybdenum mining deposit in Alaska was extensively investigated and partially reclaimed until 2012; however, in 2016, full reclaim of drill sites remained…

Environmental Degradation Due to Industrial Activities: A Case Study on Uttara EPZ, Bangladesh

The objective of this study is to classify the quality of the water and soil in the Uttara Export Processing Zone (UEPZ). In order to assess the water quality of the UEPZ, five heavy metals (Fe, Cu, Mn , Pb, Cr) were selected and two indices, such as the Heavy Metal Pollution Index (HPI) and…

Circular Natural Geoforms, Sierras Pampeanas and Chacopampeana Plain, Argentina

Structural geoforms also help us to understand the mechanisms that have given rise to them. Meteorite drop, the volcanic caldera or the intrusion of igneous bodies, and elliptical geoforms of tectonic processes are usually associated of circular geoforms. Based on visual interpretations from satellite and radar scanning images, we identify eight circular morphological features representing…

Boreholes Water Contaminated by 76 Pesticides Molecules in the Cotton Zone of Kérou

The underground water analysis campaign was carried out in 2010 on five samples of boreholes located in the agricultural cotton region. The results obtained showed that there were different active substances containing at least 76 pesticide residues, in particular insecticides , herbicides and fungicides, with an aggregate content that could average 0.350 or 350 μg…

An Approach to Bioindicators: Metal Accumulation Profile in Roadside Soils, Grass and Caesalpinia Plant Leaves

Following global industrialization, environmental pollution has risen enormously, having detrimental effects on human health and ecosystem services. Heavy metals are essential environmental contaminants, and much more attention has been paid to their toxicity to humans , plants and animals. A research was conducted in Bagalkot City (India) to investigate the heavy metal contamination of roadside…

Investigation and Documentation of Acidic Mining Exploration Drill Cuttings at the Pebble Copper– Gold Mineral Prospect, Southwest Alaska

During the Pebble copper-gold-molybdenum (Cu-Au-Mo) deposit discovery drilling, drilling waste was directly disposed of on the landscape or passed through unlined sumps prior to disposal. The ore and host rock are high in sulphides, which are weathered by metal leaching to sulfuric acid. Oxidized cuttings were visually noticeable and verified to have a pH of…
