Ecosystem engineering by periphyton in Alpine proglacial streams

Tom Ian Battin, Davide Mancini, Marc Aguet, Adrijan Selitaj, Matteo Roncoroni

Stream periphytons are candidate ecosystem engineers in proglacial margins. Here, we quantify the extent to which they are engineers for the case of hillslope-fed tributaries in the terrace zones of proglacial margin alluvial plains. Candidate ecosystem en ...

A new data set of granitic rock strength values from Yosemite Valley, California: applications to rock fall assessment

To explore connections between rock strength and rock falls, we undertook a comprehensive rock mechanics testing program for six granitic rock types in Yosemite Valley (California, USA) where rock falls are a common geomorphic and sometimes hazardous proce ...

Floating modular unit for controlled sediment flushing regarding sediment size and concentration

Giovanni De Cesare

Sediment management is a challenging discipline, especially in regions where the storage capacity of reservoirs decreases due to sediment accumulation. This paper shows an innovative and holistic modular technical approach to the problem, considering a gre ...

A locally calibrated, late glacial Be-10 production rate from a low-latitude, high-altitude site in the Peruvian Andes

Katherine Colby Leonard

Well-dated records of tropical glacier fluctuations are essential for developing hypotheses and testing proposed mechanisms for past climate changes. Since organic material for radiocarbon dating is typically scarce in low-latitude, high-altitude environme ...

Bed load fluctuations in a steep channel

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Tamara Ghilardi

Bedload transport rate fluctuations have been observed over time in steep rivers and flumes with wide grain size distributions even under constant sediment feeding and water discharge. The observed bedload transport rate pulses are periodic and a consequen ...

Period and amplitude of bedload pulses in a macro-rough channel

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Tamara Ghilardi

It is known that bedload fluctuates over time in steep rivers with wide grain size distributions, even under conditions of constant sediment feed and water discharge. Bedload fluctuations, which are a consequence of grain sorting, are periodic and are rela ...

Temporal evolution of bedload in a steep channel over a long duration experiment

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Tamara Ghilardi

Bedload fluctuations over time in steep rivers with wide grain size distributions have been observed, even under constant sediment feeding and water discharge. Observed bedload pulses are periodical and a consequence of grain sorting. Along with bedload, f ...

Sediment Transport and Flow Conditions in Steep Rivers with Large Immobile Boulders

Tamara Ghilardi

Recent flood events in Switzerland and across Europe pointed out several deficiencies in hazard assessment, planning, and prediction methods for flood risk mitigation. A good understanding of the dynamics of mountain rivers, grounded on a sound physical-ba ...
