Künstliche Hochwasser in Restwasserstrecken unter Berücksichtigung von Geschiebevorkommen, hydromorphologischer und ökologischer Indikatoren

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Christopher Robinson, Severin Stähly

Stauanlagen mit großen Speichern beeinflussen oftmals das Abfluss- und Geschieberegime im Gewässerunterlauf. Dadurch kann die natürliche Dynamik, Morphologie und Ökologie von noch verbliebenen Auenlandschaften erheblich beeinträchtigt werden. In der Saane ...

Erosion, transport and deposition of a sediment replenishment under flood conditions

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Christopher Robinson, Severin Stähly

River reaches downstream of dams with constant residual discharge often lack sediment supply and periodic high flows due to dam sediment retention and flow regulation, respectively. To test a novel multi-deposit methodology for defining environmental flows ...

Catchment land cover influences macroinvertebrate food-web structure and energy flow pathways in mountain streams

Christopher Robinson, Tom Ian Battin

Understanding how different food resources sustain stream food webs is fundamental towards increasing our knowledge on trophic structure and energy flow pathways in fluvial ecosystems. 2. Food webs in small mountain streams are sustained by autochthonou ...

Erosion processes of a novel configuration of sediment replenishment during an artificial flood

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Christopher Robinson, Severin Stähly

Floodplains downstream of dams with constant residual flow discharge often lack sediment supply and periodic inundation due to the absence of flood events. At the Sarine floodplain in Fribourg, western Switzerland, an artificial flood was released from Ros ...

Sediment replenishment combined with an artificial flood improves river habitats downstream of a dam

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Christopher Robinson, Severin Stähly

River reaches downstream dams where a constant residual flow discharge is imposed, often lack sediment supply and periodic inundation due to the absence of natural flood events. In this study, a two-year return flood was released from an upstream reservoir ...

Sampling sufficiency for determining hydraulic habitat diversity

Anton Schleiss, Walter Gostner, Mário Jorge Rodrigues Pereira Da Franca, Christopher Robinson, Severin Stähly

The geometry and hydrodynamics of river reaches are key ecohydraulic descriptors. Statistics of water depth and velocity measurements are usually taken as proxies for habitat suitability in rivers. However, little is known about the sufficiency of data to ...

Analysis of the sensitivity of the hydromorphological index of diversity, HMID

Anton Schleiss, Walter Gostner, Mário Jorge Rodrigues Pereira Da Franca, Christopher Robinson, Severin Stähly

Hydromorphological conditions are a key factor for the habitat diversity in riverine ecosystems. The Hydromorphological Index of Diversity (HMID) is a tool to quantify the habitat diversity in a river reach based on local flow depths and flow velocities. T ...

Experiments with sediment replenishment in a residual flow reach: Comparison of field datawith laboratory experiments

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Christopher Robinson, Severin Stähly

Hydropower is an important pillar of the electricity production in Switzerland and its extension is planned in the next decades. Therefore, a more sustainable management of hydropower plants is needed. Sediment replenishment combined with artificially-trig ...

Künstliches Hochwasser an der Saane - Eine Massnahme zum nachhaltigen Auenmanagement

Anton Schleiss, Christopher Robinson, Severin Stähly

Durch Wasserkraft genutzte Flüsse und Auenlandschaften sind in ihrem Abfluss- und Geschieberegime und damit in ihrer Morphologie und Ökologie oft stark beeinträchtigt. In der Saane unterhalb der Staumauer Rossens führten eine jahrzehntelange Restwasserbewi ...

Aufwertung der Habitatvielfalt in einer Restwasserstrecke mittels eines künstlichen Hochwassers und Geschiebebeigaben - Vergleich von Feldversuchen mit Laborexperimenten

Anton Schleiss, Christopher Robinson, Severin Stähly

Die Wasserkraft ist die wichtigste Säule der heutigen Schweizer Stromproduktion und deren Ausbau ist in den nächsten Jahrzehnten im Rahmen der Energiestrategie 2050 geplant. Deshalb ist ein auch nachhaltiger Betrieb der Wasserkraftwerke erforderlich. Gesch ...

SENSITIVITY ANALYSIS OF THE HYDROMORPHOLOGICAL INDEX OF DIVERSITY USING NUMERICAL GENERATED DATA

Anton Schleiss, Christopher Robinson, Pierre Bourqui, Severin Stähly

River restoration has become a priority goal in many countries. The interest in rivers as valuable habitats for floral and faunal diversity and as an ecosystem with important functions has increased. For evaluating the structural changes from a river resto ...

Glacier shrinkage driving global changes in downstream systems

Christopher Robinson, Tom Ian Battin

Glaciers cover ∼10% of the Earth’s land surface, but they are shrinking rapidly across most parts of the world, leading to cascading impacts on downstream systems. Glaciers impart unique footprints on river flow at times when other water sources are low. C ...
