Using LiDAR‐Based DEM Elevation Difference Calculations to Estimate Net Streambank Erosion in an Iowa River, USA

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Streambank erosion is an important source of sediment to river systems but is difficult to quantify at watershed scales. In this study, high‐resolution Light Detection and Ranging (LiDAR) measurements collected from 2009 and 2020 were used to quantify the difference in land surface elevation that occurred along the fourth and fifth‐order ...

Evaluation of Human Impact on Sediment Dynamics in an Intensively Managed Agricultural Watershed Using Distributed Modeling

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT By altering hydrological and geomorphological processes at watershed scales, humans have substantially influenced the movement of sediment on Earth's surface. Despite widespread recognition of human impacts on erosion and deposition, few studies have assessed the magnitude of change in watershed‐scale sediment fluxes before and after the ...

Assessing ecological vulnerability in the Kulsi River Basin, Assam using an MCDM‐based analytical hierarchical approach

open access: yesRiver, EarlyView.
Abstract The Kulsi River basin, situated in the South Kamrup district of Assam, India, is noted for its rich fish diversity and significant deposits of Pre‐Cambrian quality sand in its headstreams. These deposits gradually make their way downstream, acting as a catalyst for local livelihoods. However, the intricate ecosystem fostered by the Kulsi River

Method on sediment management for restoring the lower reach of the Kelani River, Sri Lanka

open access: yesRiver, EarlyView.
Abstract The present study describes a river channel management method for restoring riverine environments degraded by sand mining in rivers. Specifically, three conditions that must be met for a restored river channel in the lower reach of the Kelani River in Sri Lanka were proposed: (1) flood discharge capacity of the channel for a given flood, (2 ...

“It Looks as if They Threw the Entire Periodic Table Into the River”: A Decolonial Perspective for Chemistry Education in the Context of Environmental Injustices

open access: yesScience Education, EarlyView.
ABSTRACT In this article I explore the case of the Mariana dam disaster in 2015 in Brazil seeking to contribute to reflections about the role of chemistry and chemistry education in environmental injustices. Drawing on stories about this disaster shared in the Dead River Podcast (2024), on wider literature and on other cases of environmental injustices
