Lead (Pb) isotope ratios are commonly used to determine the relative contributions of anthropogenic and geogenic sources to metal contaminations in soils. For successful source apportionment, it is critical to obtain a reliable Pb isotope ratio value for each end member. However, the conventional practice for estimating the geogenic Pb isotope ratio can get affected by the anthropogenic Pb, which might produce misleading results. Therefore, this study proposes a modified approach that enhances t...
The Kachchh rift basin (KRB), located in the western continental margin of India, is very important due to repeated large magnitude occurrence of intraplate earthquakes. The present study elucidates the subsurface structural features using wavelength filtering, total horizontal derivative (THD) and 2.5 dimensional (2.5D) density modelling of the gravity data. Power spectrum analysis of the gravity data gives the cut-off wavelength of 100 km that has been used for wavelength filtering for regiona...

Recently, researchers have conducted investigations with the possibility of utilising fly ash as a barrier material, which is justified by its chemical, physical and mechanical properties. The mean necessary characteristic, which should be tested is coefficient of permeability. The diversification of test methods and sample preparation techniques can significantly change test results. The purpose of the article is to describe the fly ash permeability in dependence on compaction and moisture cont...
The Hunshandake Sandy Land (HSL) is a well-known water-rich sandy region in China that is home to many lakes. Most of these lakes are sustained by groundwater inflow. However, due to the limited hydrogeological survey data, the mechanism by which the lakes interact with groundwater is not well understood. Magnetic resonance sounding (MRS) is a geophysical method that has emerged in recent years that can directly detect the distribution of groundwater and determine the lithology of the aquifer me...

The first coal mining in India was started in the seventeenth century with an unplanned way in Raniganj coalfield, the coal capital of India. The coalfield was possessed by several small private companies which were nationalized in 1973. A part plan of Chanch/Victoria Area, Victoria West Colliery, BCCL, Raniganj Coalfield, India, indicates an underground coal mine gallery/goaf in the Begunia Coal-seam that connects to a Light Casting Factory. It was established as “Barakar Iron Works” in the yea...

The groundwater cycle pattern in the arid and semi-arid regions is drastically affected by both natural condition changes and human activities, resulting in serious eco-geological environmental problems. This paper selected the south edge of the Junggar basin as a pilot area for the basin-scale assessment of groundwater renewal capacity. Assessment indicator system was first established, assessment units were then constructed, and the Analytic Hierarchy Process method was used to identify the we...

The assessment of chronological evolution of the channel functional units is an imperative aspect to understand the channel avulsion nature and planform change. In this study, the channel functional units (channel, aggradational and abandoned) and their distinct micro-morphologies have been assessed through the landuse and landcover classification, terrain analysis, lithostratigraphic records and fluctuating flow regimes in the ancient delta fan of the Subarnarekha basin. The distinct micro-morp...

The aim of this study is the improvement of the TanDEM-X elevation model for future floodwater modeling by implementing surveyed road dams and the use of filter algorithms. Modern satellite systems like TanDEM-X deliver high-resolution images with a high vertical and horizontal accuracy. Nevertheless, regarding special usage they sometimes reach their limits in documenting important features that are smaller than the grid size. Especially in the context of 2D-hydrodynamic flood modelling, the fe...

With the increasing environmental pollution, access to clean water has become an important issue all over the world. Therefore, it is quite important to obtain new water resources or to use existing resources more effectively. In this regard, the usability of groundwater for drinking and irrigation use was investigated in Karabuk province in Turkey. The locations of wells in Karabuk province were determined and the effects of industrial and agricultural pollution on groundwater were evaluated. G...

A digital elevation model (DEM) is an essential dataset for many land feature analyses, such as geomorphological feature analyses, which are very important for many types of studies. The present study involved the evaluation of five of the most common DEMs and their derived geomorphological features in the Humrat Assahn basin. A 10-m reference DEM was generated for the study area from a contour map produced at the Royal Jordanian Geographic Center (RJGC). In addition, an aerial photography DEM w...
