Can satellite based pattern-oriented memory improve the interpolation of sparse historical rainfall records?

Anton Schleiss, Théodora Cohen Liechti, José Pedro Gamito de Saldanha Calado Matos

Ther is a standing challeng in obtaining long localized records of rainfall data in many large river basins of the developing world. Recent spaceborne instrumentation offers a constente source of rainfall information, but this information covers only a rel ...

Dynamic pressure distribution around a fixed confined block impacted by plunging and aerated water jets

Anton Schleiss, Rafael Xavier Meriade Duarte

The scour process created by the impingement of high-velocity water jets on fissured rock is the result of complex physical phenomena. Of great importance are the jet development during the trajectory through the atmosphere, the diffusion process inside th ...

Influence of the convergence angle on the morphodynamics of discordant bed confluences

António Heleno Cardoso, Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña

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 ...

Time Dependent Failure Analysis of Compressed Riprap as Riverbank Protection

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Mona Jafarnejad Chaghooshi, Michael Pfister

Riprap is a common measure for protecting river banks against lateral erosion and several methods exist to design them. However, they are generally limited to dumped medium size rocks. If large rock blocks are required for stability reasons, they cannot be ...

Scale effects related to the rating curve of cylindrically crested Piano Key weirs

Giovanni De Cesare, Anton Schleiss, Michael Pfister, Elena Battisacco

Hydraulic scale effects on physical Piano Key weir (PKW) models were so far rarely discussed in literature, even though almost all prototypes are model-tested before construction. In parallel, physical weir models are generally known to include significant ...

Discussion “Propagation of surge waves in channels with large-scale bank roughness"

Tobias Meile, Anton Schleiss

In open channels, a sudden rise in water elevation generates a positive surge. Positive surges are commonly observed in man-made channels (Bazin 1865, Treske 1994) and a natural occurrence is the tidal bore in macro-tidal estuaries (Tricker 1965, Chanson 2 ...

Closure to "Propagation os surge waves in channels with large bank roughness

Tobias Meile, Anton Schleiss

The authors thank the discusser for his interest in our work and the complementary information on the behaviour of undular surges in a channel with a local rapid constriction and expansion. ...

Investigation of turbulence flow and sediment entrainment around a bridge pier

Anton Schleiss, Elham Izadinia

Local scour around the obstacles such as bridge pier is the result of complex interaction between turbulent flow and sediment particles at the mobile bed. The entrainment of sediment particles from the bed is stochastic in nature and it is strongly influen ...

Detection of Local Wall Stiffness Drop in Steel-Lined Pressure Tunnels and Shafts of Hydroelectric Power Plants Using Steep Pressure Wave Excitation and Wavelet Decomposition

Anton Schleiss, Fadi Hachem

A new monitoring approach for detecting, locating, and quantifying structurally weak reaches of steel-lined pressure tunnels and shafts is presented. These reaches arise from local deterioration of the backfill concrete and the rock mass surrounding the li ...

Discussion of "Three-dimensional numerical study of flow structure in channel confluences"

Koen Blanckaert, Anton Schleiss, Marcelo Leite Ribeiro

The Discussers would like to congratulate the Authors for their interesting work concerning the flow characteristics in channel confluences, performed by means of three-dimensional numerical simulations considering rectangular crosssections with smooth bed ...

A review of wave celerity in frictionless and axisymmetrical steel-lined pressure tunnels

Anton Schleiss, Fadi Hachem

Generally applicable approaches for estimating the‘‘quasi-static’’, which means without fluid–structure interaction and frequency-dependent water-hammer wave speed in steel-lined pressure tunnels are analyzed. The external constraints and assumptions of th ...

Hydropeaking indicators for characterization of the Upper-Rhone River in Switzerland

Tobias Meile, Anton Schleiss

River channelization and the construction of high-head storage schemes have been the basis of agricultural and socio-economic development in many alpine regions. One example is the Upper-Rhone River in Switzerland. The Upper-Rhone's morphology changed cons ...

Experimental study of velocity fields in rectangular shallow reservoirs

Anton Schleiss, Erica Camnasio

Velocity fields in rectangular shallow reservoirs with different length-to-width and expansion ratios were investigated in an experimental study, to evaluate the effect of geometry on the flow field. A wide range of combinations of these two non-dimensiona ...

LSPIV implementation for environmental flow in various laboratory and field cases

Anton Schleiss, Sameh Ahmad Kantoush

Large-Scale Particle Image Velocimetry (LSPIV) is an extension of a quantitative imaging technique to measure water surface velocities using simple and inexpensive equipment. This paper describes the implementation of imaged-based LSPIV in eight different ...

Water-surface oscillations in channels with axi-symetric cavities

Tobias Meile, Anton Schleiss

Transverse or longitudinal movements of a water body are observed for flows along cavities, river embayments, groyne fields or harbours. They are significant for certain flow conditions and geometrical properties. To study the effect of large-scale roughne ...

Semi-empirical model for channel bed evolution due to lateral discharge withdrawal

Anton Schleiss, Burkhard Rosier

Side weirs and overtopable levees are widely used to increase flood routing along a channel or river. The lateral loss of water reduces the sediment transport capacity leading to the formation of a local sediment deposit close to the overflow. Since the ex ...
