Blockage Probability Modeling of Large Wood at Reservoir Spillways With Piers

Anton Schleiss, José Pedro Gamito de Saldanha Calado Matos, Michael Pfister, Paloma Furlan

Large wood increases the morphological and hydraulic complexity of rivers, yet it may block and modify the flood discharge capacity of hydraulic structures. To assess the related risk, blockage probability estimation for hydraulic structures such as reserv ...

Statistical accuracy for estimations of large wood blockage in a reservoir environment

Anton Schleiss, José Pedro Gamito de Saldanha Calado Matos, Michael Pfister, Paloma Furlan

The blockage of weirs or bridges by in-stream wood can reduce the flood discharge capacity, leading to hazardous situations. To assess the related risk, blocking probabilities quantifications are needed. However, large wood has a random behaviour and it is ...

Blocking probability of large wood and resulting head increase at ogee crest spillways

Paloma Furlan

Large wood increases the hydraulic complexity of rivers, yet it may block and modify the flood discharge capacity of hydraulic structures such as bridges and spillways. When spillway blockage occurs, dangerous and hazardous situations have been observed at ...

Blockage of driftwood and resulting head increase upstream of an ogee spillway with piers

Anton Schleiss, José Pedro Gamito de Saldanha Calado Matos, Michael Pfister, Paloma Furlan

Accumulations of floating debris in reservoirs can have negative impacts on the safe operation of a dam. Thus, adequate spillway design in view of driftwood is of paramount importance. Herein, investigation of driftwood blockage with a reservoir flow appro ...

Experimental repetitions and blockage of large stems at ogee crested spillways with piers

Anton Schleiss, José Pedro Gamito de Saldanha Calado Matos, Michael Pfister, Paloma Furlan

Large wood is often transported by rivers into reservoirs during heavy rainfall events. When a critical section like a spillway is blocked and discharge capacity reduced, an uncontrolled increase of the reservoir water level may occur. This study aims to s ...

Experimental Study at Prototype Scale of a Self-priming Free-Surface Siphon

Giovanni De Cesare, Paloma Furlan

This study is within the frame of the construction of the rail link between Geneva Cornavin station, Eaux-Vives station and Annemasse (CEVA). The project area is located at a cut-and-cover tunnel built by slurry walls located in the alluvium of the Foron R ...

Spillway blockage caused by large wood in reservoirs

Anton Schleiss, José Pedro Gamito de Saldanha Calado Matos, Michael Pfister, Paloma Furlan

Large wood (LW) elements are often transported by rivers into reservoirs during heavy rainfall events. Large wood has important environmental attributes that benefit the diversification of riverine ecosystems. There are several studies dealing with the tra ...

Influence of density of large stems on the blocking probability at spillways

Anton Schleiss, José Pedro Gamito de Saldanha Calado Matos, Michael Pfister, Paloma Furlan

Dam safety is strongly linked to the probability of occurrence of large floods. Floods can transport large wood (LW) into reservoirs and towards water release structures as spillways. Due to blocking and clogging, LW may significantly influence the dischar ...

BLOCKING PROBABILITY OF DRIFTWOOD AT OGEE CREST SPILLWAYS WITH PIERS: INFLUENCE OF WOODY DEBRIS CHARACTERISTICS

Anton Schleiss, José Pedro Gamito de Saldanha Calado Matos, Michael Pfister, Paloma Furlan

Spillways are designed to evacuate floods in a safe way. They should safely release water in order to avoid dam overtopping with its related damages. Nevertheless, it may be dangerous to assume that a flood is only carrying “clear” water. Large woody debri ...

Entrainement de bois flottant dans un déversoir a crête standard avec piliers: Influence des caractéristiques de bois flottant en probabilités de blocage

Anton Schleiss, José Pedro Gamito de Saldanha Calado Matos, Michael Pfister, Paloma Furlan

Spillways are safety elements of dams that allow to release floods. They spill water to avoid overtopping with its potential structural damages at the dam and the downstream environment. Nevertheless it may be unsafe to assume that a flood only carries cle ...
