Large-Scale Channel Response to Erosion-Control Measures

Erosion-control measures in rivers aim to provide sufficient navigation width, reduce local erosion, or to protect neighboring communities from flooding. These measures are typically devised to solve a local problem. However, local channel modifications trigger a large-scale channel response in the form of migrating bed level and sediment...

Closing the Wound: an Eye-Opening Mechanism: Development of a Bi-planar Incision Mechanism Used in Vitrectomy

Background: Treatment of eye conditions, such as retinal detachment, macular pucker or macular holes, ask for an intervention named ”vitrectomy”. In a vitrectomy, multiple surgical instruments are brought into the eye, to facilitate removal of the vitreous humor. The instruments enter the eye through trocar ports that are placed in the sclera....

Centennial Channel Response to Climate Change in an Engineered River

Human intervention makes river channels adjust their slope and bed surface grain size as they transition to a new equilibrium state in response to engineering measures. Climate change alters the river controls through hydrograph changes and sea level rise. We assess how channel response to climate change compares to channel response to human...

The Compressiometer: Towards a new skin tensiometer for research and surgical planning

After surgery, around 35% of patients experience problems of excessive scarring, causing disfiguring and impaired function. An incision placed in the wrong direction causes unnecessary skin tension on the wound, resulting in increased collagen disposition and potentially hypertrophic scars. Currently, skin tension lines are used for incision...

River Response to Anthropogenic Modification: Channel Steepening and Gravel Front Fading in an Incising River

While most of the world's large rivers are heavily engineered, channel response to engineering measures on decadal to century and several 100 km scales is scarcely documented. We investigate the response of the Lower Rhine River (Germany-Netherlands) to engineering measures, in terms of channel slope and bed surface grain size. Field data...

Uplift of the Transdanubian Range, Pannonian Basin: How fast and why?

The cumulative incision rates of ~50–70 m/Ma integrating over the last ~3 Ma have been derived from published terrace-chronological data of the Danube river in the Western Pannonian Basin. An apparent acceleration of uplift rates was observed for shorter timescales culminating at ~200 m/Ma over the last ~140 ka. An examination of the change...

Long-eccentricity regulated climate control on fluvial incision and aggradation in the Palaeocene of north-eastern Montana (USA)

Aggradation and fluvial incision controlled by downstream base-level changes at timescales of 10 to 500 kyr is incorporated in classic sequence stratigraphic models. However, upstream climate control on sediment supply and discharge variability causes fluvial incision and aggradation as well. Orbital forcing often regulates climate change at...

Preservation of Last Interglacial and Holocene transgressive systems tracts in the Netherlands and its applicability as a North Sea Basin reservoir analogue

Understanding of complex sedimentary records formed by transgressive systems is critical for hydrocarbon exploration and exploitation, and carbon capture and storage. This paper discusses the facies proportions and preservation of the Last Interglacial and Holocene transgressive systems tracts in the Netherlands and their applicability as a...
