Remote Sensing of River Discharge Based on Critical Flow Theory

open access: yesGeophysical Research Letters, Volume 52, Issue 9, 16 May 2025.
Abstract Critical flow theory provides a physical foundation for inferring discharge from measurements of wavelength and channel width made from images. In rivers with hydraulically steep local slopes greater than ∼ ${\sim} $0.01, flow velocities are high and the Froude number Fr $Fr$ (ratio of inertial to gravitational forces) can approach 1.0 ...

Linking permafrost to the abundance, biomass, and energy density of fish in Arctic headwater streams

open access: yesEcosphere, Volume 16, Issue 5, May 2025.
Abstract Permafrost thaw alters groundwater flow, river hydrology, stream‐catchment interactions, and the availability of carbon and nutrients in headwater streams. The impact of permafrost on watershed hydrology and biogeochemistry of headwater streams has been demonstrated, but there is little understanding of how permafrost influences fish in these ...

WATER MANAGEMENT POLICIES FOR STREAMFLOW AUGMENTATION IN AN IRRIGATED RIVER BASIN [PDF]

open access: yes
The value of maintaining a minimum streamflow objective on average is lessened when there is considerable dispersion around the average. An integrated economic and hydrology model is presented which provides water policy planners with a way to accurately

Storage Dynamics and Groundwater–Surface Water Interactions in a Drought Sensitive Lowland Catchment: Process‐Based Modelling as a Learning Tool

open access: yesHydrological Processes, Volume 39, Issue 5, May 2025.
The past two decades have been dominated by negative anomalies in annual rainfall, causing a general lowering of water tables and persistent storage deficits. Spatio‐temporal patterns of recharge are also strongly influenced by vegetation cover, with coniferous forests having high evapotranspiration losses that inhibit groundwater recharge. Most stream

Assessment of Saturated Hydraulic Conductivity‐Depth Relationships and Extended Soil Column Thickness in Catchment Hydrological Modelling

open access: yesHydrological Processes, Volume 39, Issue 5, May 2025.
We assessed the extension of the soil column in gridded catchment rainfall–runoff modelling as an approach to sufficiently capture the shallow groundwater system and its interaction with the rest of the catchment hydrological processes. We implemented and assessed different vertical profiles of saturated hydraulic conductivity that exceed the typical ...

Variability in Hydrologic Response to Wildfire Between Snow Zones in Forested Headwaters

open access: yesHydrological Processes, Volume 39, Issue 5, May 2025.
Model results showed that a stormflow response was more likely in the high snow zone (HSZ) than in the low snow zone (SZ)L, likely due to the higher soil moisture content. Rainfall intensity was a good predictor of the magnitude of the stormflow response, whereas burn category influenced the lag to peak times.
