The concept of the Borehole Diffusive Flux Apparatus (BDFA) is presented herein. The BDFA is an innovative apparatus designed to provide continuous direct access to an undisturbed column of sediment that can be monitored at multiple discrete vertical intervals to provide high-resolution characterization of local-scale mass transfer and attenuation....

The main purpose of the present study, conducted in the Piedemonte Llanero of Colombia, was to identify the role of covariates that influence soil properties under different land uses by analyzing the dynamics of selected soil properties in natural and agricultural areas. Soil samples were collected from 90 different sites throughout the region, 45...

Building on expansive soil is risky due to its high compressibility, low shear strength, and differential settlement. This study evaluates the potential of the use of sodium hydroxide (NaOH) as an additive to improve the stability of clay. For this research, the compaction properties namely Dry Density, Optimum Moisture Content, Atterberg Limits, a...

Blasting impact disturbances have an important influence on the safety of underground engineering openings. In this article, in-situ stress measurements and a structural plane investigation were conducted in a gold mine, and a numerical model of roadways through jointed rock masses was established using 3DEC software. The instability and failure ch...

In this study, an attempt was made to understand the hydrogeochemical processes controlling water resources (surface and groundwater) evolution in El Fayoum depression, Egypt. Hydrochemical, inverse geochemical modeling integrated with environmental isotopes was applied. Forty-three surface and groundwater samples were collected and analyzed for ma...

To assess the potential risk of Mining Influenced Water (MIW) contaminating the “Cradle of Humankind” Unesco World Heritage site (“Fossil Hominid Sites of South Africa”), flow measurements were conducted in the Tweelopiespruit, a stream influenced by treated mine water from abandoned gold mines in the Witwatersrand gold fields (South Africa). A pos...

The slope stability has already become one of the most important factors directly related to the safety production and development of a mine, which is principally controlled by the properties of geological discontinuities of slope, such as bedding planes, faults, cleavage and joints. In this study, a new approach for the evaluation of slope stabili...

Sulfentrazone is an important herbicide in the management of weeds that are difficult to control in crops such as soybeans and sugarcane. With the increase in cases of herbicide-resistant weeds, the trend is that pre-emergence application of sulfentrazone will be more widespread in the coming years. This may result in a greater likelihood of contam...

The cultural heritage of the different regions demonstrates the identity of individuals who have lived from the past to the present. Today, with the development of cities, some of these cultural assets have been forgotten or are being destroyed. Therefore, documenting this worthy heritage is vitally important for preserving, conserving, or introduc...

Hydrochemical assessment of the Cauvery River Basin (CRB), an east flowing Western Ghats (WG) river, is carried out to understand the dissolved load sources and controlling mechanisms with quantification of source-wise input to the dissolved load. Silicate weathering rates (SWR) and associated CO2 consumption rates (CCR) are evaluated on account of...
