Long‐Term Effects of Low‐Drop Grade Control Structures on Channel Evolution in the Yazoo River Basin
ABSTRACT Channel incision is a widespread problem, especially in river basins that have an extensive history of channel alterations. Because channel incision causes large ecological and economic consequences, the prevention of continued migration of headcuts, defined as a steep change in stream gradient over a short reach, has been the focus of many ...

Successful valley bottom restoration requires an understanding of current and historical conditions determining whether a reach can currently support a multi‐thread or meandering channel, an understanding of reference conditions to assist with design, clear objectives to evaluate design alternatives, and post‐project monitoring of success using a ...

The ability to perform a number of ecosystem functions is degraded by the inappropriate damming of agricultural floodplains (by levee construction) or by the continuous urban expansion, where flood protection is justified but at the cost of affecting the environmental stability of the wider landscape.

Chronological Study of Fluvial Terraces along the Jusu River, Eastern Korea
A series of fluvial terraces is well developed along the Jusu River flowing into the eastern side of the Taebaek Mts., Korea. Among these terraces, the development of the most well-preserved lower terraces were examined in connection with the climatic and sea-level changes since Last Interglacial by an investigation into the deposits and longitudinal ...

In extreme heavy snowfall environments (maximum snow depth of 5 m), dominant species such as Pterocarya rhoifolia and Aesculus turbinata exhibited different survival strategies—sprouting, dwarfing, and layering—compared to their tall forms in heavy snowfall areas (maximum 2 m).

Provenance records from the late Palaeozoic Marfa Basin in West Texas reveal the transition from the Ancestral Rocky Mountains to the Ouachita–Marathon–Sonora orogenies during the early Permian in SW Laurentia. ABSTRACT The Marfa Basin in West Texas is a late Palaeozoic synorogenic depocenter associated with regional deformation linked to the Ancestral

Palaeochannels of the upper central Murray and lower Goulburn rivers, southeastern Australia
Palaeochannel systems are characteristic of alluvial plains across large parts of the Australian continent, but their evolution and modes of formation are still only partly understood.

X‐ray computed tomography study of terrestrial analog cores in preparation for Mars sample return
Abstract Mars Sample Return (MSR) is expected to transform planetary science by providing unprecedented access to pristine Martian material. Initial characterization in the sample receiving facility (SRF) will rely on nondestructive techniques such as X‐ray computed tomography (XCT) to document the condition, distribution, and internal features of ...

The Dniester valley is a spectacular example of a degrading bedrock fluvial system at the contact between the East European platform and the Carpathian orogen. This study is based upon a combined lithofacies–architecture–morphological study.
