The present study was carried out to evaluate performance of Agricultural Policy Environmental eXtender (APEX) integrated with GIS as ArcAPEX model in simulating surface runoff, sediment and nutrients loss from a watershed located in lesser Himalayan region in Uttarakhand state, India. Daily surface runoff, sediment and nutrient loss data measured ...

We applied a hybrid-dimensional flow model to pressure transients recorded during pumping experiments conducted at the Reiche Zeche underground research laboratory to study the opening behavior of fractures due to fluid injection. Two distinct types of pressure responses to flow-rate steps were identified that represent radial-symmetric and plane-a...

The study examined the reliability of injection wells (IWs) as a control measure of flood and flood-related activities considering the relevance and the role of groundwater to human and industrial activities. Seventeen Boreholes (BHs) including one as control, and three IWs in Government Reservation Area (GRA), Benin Metropolitan City (BMC) were us...

Coastal regions are quite populous, causing coastal aquifers to be overexploited, due to which contamination of these aquifers is observed. The municipality of Belém, located on the eastern edge of the Amazon Forest, is severely deficient with respect to sanitation services, resulting in contamination by domestic wastewater becoming a widespread pr...

The invasion created by drilling fluids around borehole walls creates considerable variations on mechanical and physical properties of both rock materials and discontinuities. However, up to date there is no comprehensive study has been performed on the variation of fracture toughness values of rocks under drilling fluid saturation with different c...

The dynamic variations of groundwater have been extensively studied, but there are few studies on the long-term time–frequency features of groundwater dynamic variations. Here we report the dynamic characteristics of the groundwater level and dissolved radon concentration based on the long-term (January 1988–March 2018) daily observation records an...

The low-lying coastal basins of Ravenna (Italy) are at or below mean sea level and currently undergoing land subsidence, which exposes the basins to frequent inundation and groundwater and soil salinization. The surface water drainage becomes necessary to lower the water table head and further prevent flooding and waterlogging. The study examines t...

This study aims to investigate the combined effects of temperature and precipitation on the hydrological processes in a watershed with intensive agricultural land uses during the spring snowmelt period. Temperature, precipitation, soil moisture, frozen soil depth, and discharge were monitored during the freezing and thawing periods in 2014, 2015, a...

The sudden outburst of coal and gas is a complex and dynamic incident in the underground coal mines, resulting in the release of thousands of tons of coal and large amounts of gas into the working face within a short time. Due to a rise in the number of exploitations and the depth of extractions, the intensity, and frequency of explosions have incr...

This study focuses on interpreting Bouguer gravity anomalies by two-sided fault structures. Faults have prime concerns for hazardous zones, mineralized areas, and hydrocarbon systems. The proposed scheme is done through the following steps: first, it utilizes the residual moving average anomalies estimated from the Bouguer gravity anomalies using s...
