Cryospheric Hydrometeorology Observation in the Hulu Catchment (CHOICE), Qilian Mountains, China
Understanding cryospheric hydrology and the effects of cryospheric changes on river runoff is critical for sustainable water management especially in arid inland river basins such as those in northwest China where water resources mainly come from alpine areas. A cryospheric hydrometeorology…

Effect of Soil Texture on Estimates of Soil-Column Carbon Dioxide Flux Comparing Chamber and Gradient Methods
A key component of the global C balance includes soil CO emissions. Both chamber- and gradient-based methods have been effectively used for determination of soil CO efflux. The gradient-based method, however, is installed belowground and requires assessment of the soil gas diffusion coefficient…

The Hupsel Brook Catchment: Insights from Five Decades of Lowland Observations
The 6.5-km Hupsel Brook catchment has been used as an example rural lowland area to understand rainfall–runoff processes, land–atmosphere interactions, and solute transport and to investigate how they are affected by changes in land use and water management. Meteorological and hydrological…

Episodic Master Recession Evaluation of Groundwater and Streamflow Hydrographs for Water-Resource Estimation
Hydrograph analysis tools using a master recession curve (MRC) can produce many types of hydrologically important watershed-response quantifications, including aquifer recharge and stormflow characterization. An MRC is the relation between the value of a measured response and its rate of change…

Soil Water Dynamics of Shallow Water Table Soils Cultivated With Potato Crop
Agricultural areas with shallow water tables usually rely on upward soil water flux to supply crop evapotranspiration (ETc). The study objective was to determine optimum water table levels for coarse-textured soils cultivated with potato ( L.) by estimating the upward soil water flux under…

Riparian Vadose Zone Preferential Flow: Review of Concepts, Limitations, and Perspectives
The design and analysis of surface water pollution control practices such as vegetative filter strips and riparian buffers typically focus on surface runoff, with limited attention given to subsurface flow and transport. Field evidence suggests a prevalence of macropore flow (MF) in the riparian…

Characterizing Redox Potential Effects on Greenhouse Gas Emissions Induced by Water-Level Changes
Soil greenhouse gas (GHG) emissions contribute to global warming. To support mitigation measures against global warming, it is important to understand the controlling processes of GHG emissions. Previous studies focusing mainly on paddy rice fields or wetlands showed a strong relationship between…

Preferential Flow in Different Soil Architectures of a Small Karst Catchment
In karst regions, soil architecture varies along topographical locations, resulting in marked differences in infiltration rates. However, the relationship between soil architecture and preferential flow (PF) is still unclear. In this study, dye tracing was used to investigate PF and the dominant…

Canopy Chamber Measurements of Carbon Dioxide Fluxes in Corn and Soybean Fields
Crop canopy CO exchange rate (CER) includes crop photosynthesis and soil/plant respiration. A portable canopy chamber is effective in determining crop CER values at a relatively small spatial (m) scale. The objectives of this study were to use a canopy chamber to measure CO fluxes in corn ( L.) and…

SNO KARST: A French Network of Observatories for the Multidisciplinary Study of Critical Zone Processes in Karst Watersheds and Aquifers
Karst aquifers and watersheds represent a major source of drinking water around the world. They are also known as complex and often highly vulnerable hydrosystems due to strong surface–groundwater interactions. Improving the understanding of karst functioning is thus a major issue for the efficient…

Specific Conductance as a Tracer of Preferential Flow in a Subsurface-Drained Field
Specific conductance (SC), soil volumetric water content (VWC), and discharge were monitored on a subsurface agricultural drain for a 2-yr period (2007–2008) to differentiate preferential flow paths from matrix flow paths. A major observation from the 2-yr period was the fast SC decrease after…

Hydropedological Interpretation of Regional Soil Information to Conceptualize Groundwater–Surface Water Interactions
Understanding and quantifying groundwater–surface water interactions is important for effective water resource management. Characterization of these interactions is difficult due to heterogeneities in landscapes and difficulties in measuring hydrological processes at different scales. Although…
