Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.

SWCCs and permeability functions for coarse-grained soils

open access: yes, 2010
An understanding of soil-water characteristic curves (SWCCs) and permeability functions for coarse-granular soils is essential to the study of failure mechanisms in colluvium deposits.

Meander‐Bend Erosion Dynamics Along a Gravel‐Bed River: Insights From Short‐Term UAV Monitoring

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Riverbank erosion is a natural process in meandering rivers that contributes to sediment supply and geomorphic diversity, yet it can threaten infrastructure and human activities within the floodplain. Recently, many studies have used high‐resolution remote sensing technologies to measure bank erosion, but they often focus on technical aspects ...

Statistical Evaluation of Sleeve Friction to Cone Resistance Ratio in Coarse-Grained Soils

open access: yes
The investigation of soil is a particularly important stage of structural design. Cone penetration tests (CPTs) are the most common soil investigation techniques. The results of these tests provide information about the values of cone resistance (qc) and

Assessing Spatial Riverbed Clogging and Its Dynamics at the Reach Scale: A Coupled Approach Combining Field Measurements and 1D Hydro‐Sedimentary Numerical Modeling

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Assessing spatial and temporal variability of clogging in gravel‐bed rivers is challenging because field methods typically rely on labor‐intensive measurements of fine‐sediment content, porosity, or hydraulic conductivity. Clogging is also highly dynamic, driven by hydro‐sedimentary conditions; yet few studies have examined it at large scales ...

Fundamental Hydraulic Geometry Relations as an Accessible Tool for Identifying Channel Instability Over National Scales

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT The geometry of alluvial river channels can give insight into their stability, which can inform predictions of morphological change, flood risk and ecological degradation. Fundamental hydraulic geometry relations can be used to estimate the equilibrium dimensions of stable river channels by evaluating the balance between the erodibility of bed

Restoring Lateral Connectivity to Anthropogenic Riverscapes: Six Lessons From Stage Zero

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Centuries of river modification, particularly straightening and incision, have severely reduced lateral connectivity between rivers and their floodplains. As a result, Stage 0 riverscapes, characterised by high lateral connectivity (e.g., anastomosing or wetland riverscapes), are now rare in anthropogenic landscapes.

Detecting Plateau Zokor (Eospalax baileyi) Mounds in UAV Imagery of Alpine Meadows Using Deep Learning Algorithms

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We developed PZM‐YOLO to automatically detect plateau zokor mounds in UAV imagery of alpine meadows. The model achieved reliable detection of small and densely distributed mounds under complex backgrounds, outperforming the baseline YOLOv5s. This framework supports mound counting, mound position, rodent impact assessment, and grassland restoration ...

The soils of the southeastern sector of Egmont National Park

open access: yes, 1970
The soils of the southeastern slopes of Egmont National Park, Taranaki, are youthful in absolute age and also in soil development. They are classed as recent soils on a parent material basis: andesitic tephras, alluvium, and peat with interbedded tephra.
