The influence of added mass on rock block uplift in plunge pools

Anton Schleiss, Erik Bollaert, Matteo Paolo Elia Antonio Federspiel

Within the fluvial network, confluences are particular areas characterized by great ecological value where flow dynamics and bed morphology are much influenced by local patterns. The aim of this article is to describe the influence of the convergence angle ...

Response of an Embedded Block Impacted by High-Velocity Jets

Matteo Paolo Elia Antonio Federspiel

High-velocity plunging jets, issuing from ood release structures of dams, may result in scouring of the rocky riverbed and even endanger the foundation of the dams. Assessment of the scour extent is essential to ensure the safety of the dam and appurtenant ...

The 115 m high Koman Dam is located in the northern part of Albania and is part of the Drin River hydroelectric cascade. The dam is equipped with two tunnel spillways with flip buckets at their downstream limits. Two large scour holes were created in the d ...

Response of an embedded block impacted by high-velocity jets

Matteo Paolo Elia Antonio Federspiel

The safety of dams is very often endangered by the formation of scour near the foundation as a result of high-velocity jet impact. These jets issue from appurtenant structures such as spillways and may impact in the immediate vicinity of the dam toe. The p ...

Energy dissipation downstream of Piano Key Weirs – Case of study of Gloriettes Dam (France)

Martin Peter Bieri, Matteo Paolo Elia Antonio Federspiel

The Gloriettes concrete arch dam in the French Pyrenees showed a deficit of 80 m3/s for the new design flood of 150 m3/s. To address the problem, a Piano Key Weir (PKW) as an additional spillway was designed. The existence of a geotechnically unstable zone ...

Flood release structures of high-head dams generate high-velocity plunging jets. These may scour the downstream rocky riverbed and even damage the dam foundation. Assessment of the scour evolution is essential to ensure the safety of the dam and appurtenan ...

Spillway discharge capacity upgrade at Gloriettes dam

Martin Peter Bieri, Matteo Paolo Elia Antonio Federspiel

In many countries dams are found to have insufficient flood discharge capacity with respect to updated design floods. Upgradig of spillway discharge capacity has therefore become a significant issue for operators of hydropower plants. The Gloriettes concre ...
