Phytoplankton and Temperature Control Seasonal Dynamics of Greenhouse Gases in a Large River

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Rivers are a dynamic source of greenhouse gases (GHGs), yet the temporal variability and controlling mechanisms of their CO2:CH4:N2O ratios remain poorly constrained. We monitored the three GHGs in the German river Elbe over 5 years at two sites to identify seasonal controls as well as travel time related and site‐specific mechanisms driving ...

Accuracy and Limitations of Tools for Analyzing Meander Migration: Consequences of Bend Dynamics and Analysis Interval

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract Channel migration in meandering rivers is commonly quantified by analyzing change over time in positions of river‐channel centerlines extracted from aerial photographs or satellite images. Although several tools have been developed to estimate migration based on centerline changes, the accuracy of these tools has not been rigorously evaluated.

Management Options for the Inland Fisheries Resource in South Sumatra, Indonesia: I Bioeconomic Model [PDF]

open access: yes
The inland fishery in South Sumatra, Indonesia, is an important source of income, employment and protein to small-scale fishers. Some overall indicators, such as virtual disappearance of certain important species and continuous reduction in the size of ...

Entrainment of Muddy Sediment From Immobile Gravel River Beds

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract This study examines the transport of fine muddy sediment through a gravel‐bed reach. In such cases, mud is often conceptualized as a size fraction that interacts little with the bed (i.e., as washload). However, previous studies have shown that mud can deposit within gravel beds.

Hydraulic Effects of Channel Realignment and Floodplain Reconnection in a Headwater Stream

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract Channel realignment and floodplain reconnection are increasingly used as nature‐based solutions for flood management, yet their hydraulic effects remain poorly quantified in field settings of moderate‐gradient, small order channels. This study examines the impact of such interventions on hydraulic response in a headwater catchment, Goldrill ...
