National soil hydrologic groups map for environmental applications using data-driven and expert-based methods [PDF]

Scientific Data
Regional and national 3D soil hydraulic maps enhance understanding of soil hydraulic properties, essential for environmental assessments. However, data aggregation is often necessary in large-scale models to facilitate the modelling of complex soil ...

Technical Note: Space–time statistical quality control of extreme precipitation observations [PDF]

Hydrology and Earth System Sciences, 2022
Information about precipitation extremes is of vital importance for many hydrological planning and design purposes. However, due to various sources of error, some of the observed extremes may be inaccurate or false.

Bayesian Calibration Points to Misconceptions in Three‐Dimensional Hydrodynamic Reservoir Modeling

Water Resources Research, 2023
Three‐dimensional (3d) numerical models are state‐of‐the‐art for investigating complex hydrodynamic flow patterns in reservoirs and lakes. Such full‐complexity models are computationally demanding and their calibration is challenging regarding time ...

An interdisciplinary model chain quantifies the footprint of global change on reservoir sedimentation

Scientific Reports, 2023
Global change alters hydro-climatic conditions, affects land use, and contributes to more frequent droughts and floods. Large artificial reservoirs may effectively alleviate hydro-climatic extremes, but their storage capacities are threatened by ...

Seasonal Dynamics of Gaseous CO₂ Concentrations in a Karst Cave Correspond with Aqueous Concentrations in a Stagnant Water Column

Geosciences, 2023
Dissolved CO2 in karst water is the key driving force of karstification. Replenishment of CO2 concentrations in karst water occurs by meteoric water that percolates through the vadose zone, where CO2 produced from microbial activity is dissolved. CO2 can

Heat transport from atmosphere through the subsurface to drinking‐water supply pipes

Vadose Zone Journal, 2023
Drinking‐water quality in supply pipe networks can be negatively affected by high temperatures during hot summer months due to detrimental bacteria encountering ideal conditions for growth.

Indirect downscaling of hourly precipitation based on atmospheric circulation and temperature [PDF]

Hydrology and Earth System Sciences, 2013
The main source of information on future climate conditions are global circulation models (GCMs). While the various GCMs agree on an increase of surface temperature, the predictions for precipitation exhibit high spread among the models, especially in ...

Experimental study on retardation of a heavy NAPL vapor in partially saturated porous media [PDF]

Hydrology and Earth System Sciences, 2017
Non-aqueous-phase liquid (NAPL) contaminants introduced into the unsaturated zone spread as a liquid phase; however, they can also vaporize and migrate in a gaseous state.

Understanding variations in downwelling longwave radiation using Brutsaert's equation [PDF]

Earth System Dynamics, 2023
A dominant term in the surface energy balance and central to global warming is downwelling longwave radiation (Rld). It is influenced by radiative properties of the atmospheric column, in particular by greenhouse gases, water vapor, clouds, and ...

Machine learning assists in increasing the time resolution of X-ray computed tomography applied to mineral precipitation in porous media

Scientific Reports, 2023
Many subsurface engineering technologies or natural processes cause porous medium properties, such as porosity or permeability, to evolve in time. Studying and understanding such processes on the pore scale is strongly aided by visualizing the details of
