Actualization of prospects of thermal usage of groundwater of mines during liquidation [PDF]

E3S Web of Conferences, 2019
The aim of the paper is justification of the economically efficient technological scheme for development of a thermal resource of “Stashkov” mine after its closure, ensuring the maintenance of a favorable energy and ecological-hydrogeological regime in ...

Non‐Physical Barrier Design and Environmental Conditions Alter Routing and Survival of Juvenile Chinook Salmon (Oncorhynchus tshawytscha) in the Sacramento‐San Joaquin River Delta

River Research and Applications, EarlyView.
ABSTRACT Pacific salmon face substantial challenges when migrating through anthropogenically modified river systems, such as the Sacramento‐San Joaquin River Delta (the Delta). Non‐physical behavioral barriers, such as the bioacoustic fish fence (BAFF), are one potential solution for guiding fish away from hazards without obstructing water flow ...

AR, CR and ARCR modeling for simulations and analyses of karst groundwater quality parameters [PDF]

Geološki Anali Balkanskoga Poluostrva, 2018
Although an invisible component of the hydrologic cycle, groundwater generally takes precedence over other water resources in the area of drinking water supply.

Search and Passage Are Decoupled for Migrating Trout Kelts at Multi‐Exit Dam

River Research and Applications, EarlyView.
ABSTRACT Longitudinal and lateral river connectivity have been drastically reduced over time, with hydropower development as a major driver of fragmentation. While fishways are widely implemented to support upstream migration, downstream passage remains a major challenge.

Seismic hydrogeology: Review and prospects

Shuiwen dizhi gongcheng dizhi
Seismic hydrogeology, as a cross-disciplinary field studying the interactions between seismic events and groundwater systems, aims to address the lack of systematic review and unclear definition of the scope and connotations within this field. This paper

Seasonal Variation in Carbon Dynamics in the Lower Tocantins River: Influence of Discharge and Environmental Drivers

River Research and Applications, EarlyView.
ABSTRACT Tropical rivers play a key role in regional carbon budgets, yet greenhouse gas (GHG) dynamics in regulated systems remain poorly understood. This study investigates the seasonal variability of carbon dioxide (CO2) and methane (CH4) concentrations, isotopic composition (δ13C), and river‐atmosphere fluxes in the lower Tocantins River, a ...

Mechanism of Structural Evolution of Limestone of Qinghai–Xizang Plateau Under Coupling Effect of Freeze–Thaw Cycles and Hydrochemical Erosion

Geofluids
The scientific understanding of the evolution of limestone structure under the combined action of freeze–thaw cycles (F-T cycles) and hydrochemical solutions is of great significance for revealing the mechanism of frost damage generation in cold ...

A Method for Identifying Rainfall‐Runoff Events at Sub‐Hourly Time Scales: Applications for Nature‐Based Solutions and Water Resources

River Research and Applications, EarlyView.
ABSTRACT Understanding how changes in catchment conditions affect ecohydrology in response to rainfall‐runoff events is crucial when developing informed strategies to enhance flow resilience, restore natural habitats, interpret water quality data or reduce flood risk.

The Fargo‐Moorhead Diversion: Flood Protection or Sprawl Promotion?

River Research and Applications, EarlyView.
ABSTRACT Urban growth and development opportunities are needed worldwide, but growth and development must be hazard‐aware and should follow smart‐growth principles. The $2.89 billion Fargo‐Moorhead Area Diversion Project was designed to provide flood protection following damaging floods on the Red River of the North.

Hydrogeology of Gypsum formations [PDF]

International Journal of Speleology, 1996
Detailed explanation of hydrogeological characteristics of gypsum aquifers is given in various situations: deep-seated karst-confined conditions, subjacent, entrenched and denuded karst types-semi-confined, phreatic and vadose conditions.
