Extended Strahler Ordering to Distinguish Mapped River Channels From Overland Flow Pathways and Consistently Compare Digital Networks

River Research and Applications, EarlyView.
ABSTRACT Digital networks are virtual representations of freshwater systems that provide important inputs to, and mapping of, river classifications, simulation models, and quantitative data analyses for policy, planning, and management. Strahler order has often been used to characterize network configuration and as a proxy indicator of river channel ...

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR

River Research and Applications, EarlyView.
ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.

Software to Support Remote Sensing of River Discharge Based on Critical Flow Theory

River Research and Applications, EarlyView.
ABSTRACT Water resource management requires accurate observations of streamflow but standard field methods for measuring river discharge (Q$$ Q $$) can be costly and hazardous for equipment and personnel. Remote sensing has become a viable alternative, but many image‐based techniques require field data for calibration, and depth and velocity can seldom

Benthic Macroinvertebrate Recovery After Wastewater Treatment Plant Upgrades: Implications for Biomonitoring

River Research and Applications, EarlyView.
ABSTRACT During the past decade, major upgrades have been made to the Kitchener and Waterloo wastewater treatment plants (WWTPs) in the Grand River watershed in Ontario, Canada. As part of efforts to evaluate the effectiveness of these investments (>$450 M CDN), a benthic macroinvertebrate (BMI) monitoring program was initiated by sampling upstream and
