Large-Scale Segmentation of the Paraguay River Based on Morphological and Hydro-Sedimentary Criteria
Hydro-geomorphological dynamics in the Pantanal wetlands remain poorly understood, requiring more comprehensive investigations. Geomorphological compartmentalization has been particularly useful in this endeavor, although such approach presents ...

ABSTRACT The pattern of flow or hydrological connection between a river's main channel and its floodplain can vary seasonally and spatially in frequency, duration, direction, and magnitude. Such variation is expected to promote habitat and biotic diversity.

Making Waves: The Effects of Whitewater Parks on Fish Passage in Colorado
ABSTRACT Instream structures have fragmented riverine habitats throughout much of the world, including the Western USA. Whitewater parks (WWPs) are relatively new instream structures designed to create hydraulic waves for recreational boating and surfing by constricting flows into a steep chute or drop.

Evaluating the Interpretation Uncertainty From the Manual Streambank Delineation
ABSTRACT Streambank delineation enables the development of two important parameters: streambank position and channel width. For older aerial images that cannot be easily processed by automatic methods, manual interpretation of streambanks is a necessary task.

Floodplain environmental change during the younger dryas and holocene: Evidence from the lower kennet valley, south central England [PDF]
Many lowland rivers across northwest Europe exhibit broadly similar behavioural responses to glacial-interglacial transitions and landscape development. Difficulties exist in assessing these, largely because the evidence from many rivers remains limited

ABSTRACT Braided rivers are some of the most dynamic and complex river systems in the world. They provide unique habitat to rare species, supply natural resources, and act as a source of groundwater recharge. However, they can also pose significant flooding and erosion hazards. Current management of braided rivers in Aotearoa New Zealand faces a strong

Abstract Carbon dioxide (CO2) evasion and downstream export of carbon (C) from headwater streams represent important fluxes in the global C cycle. Yet, these fluxes are generally studied in isolation, leaving gaps in the understanding of the overall role of streams in the C cycle.

Abstract For over a century, alluvial river terraces have been used as archives of tectonic deformation or changes in water discharge, sediment supply, and sea level. Despite this long history, such efforts remain challenging: using terraces as deformation markers requires knowledge of their initial geometry, and most attempts to attribute terrace ...

Assessing the Viability of Complex Electrical Impedance Tomography (EIT) with a Spatially Distributed Sensor Array for Imaging of River Bed Morphology: a Proof of Concept (Study) [PDF]
This report was produced as part of a NERC funded ‘Connect A’ project to establish a new collaborative partnership between the University of Worcester (UW) and Q-par Angus Ltd.

Abstract Hyper‐velocity impacts on planetary surfaces lead to impact craters whose morphology evolves due to exogenous factors such as atmospheric processes, as well as endogenous factors including tectonic and metamorphism. On Earth, erosion processes driven by climate (fluvial, aeolian, glacial processes) progressively erase these structures, or even
