Design of sediment detention basins: Scaled model experiments and application

Anton Schleiss, Mona Jafarnejad Chaghooshi, Sebastian Schwindt, Anita Hélène Roth

Sediment detention basins are implemented on mountain rivers to trap solid material that may aggravate the flooding of downstream settlements. However, retention structures built in the past may unnecessarily retain sediment during non-hazardous flood even ...

Effect of a second layer on the time to failure of compressed riprap as mountain riverbank protection

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

Recently, Jafarnejad, Franca, Pfister, and Schleiss [2017. Time-based failure analysis of compressed riverbank riprap. Journal of Hydraulic Research, 55(2), 224–235. doi: 10.1080/00221686.2016.1212940] presented an experimental study on the stability of co ...

Design of Riverbank Riprap Using Large, Individually Placed Blocks

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

The protection of river banks in mountain rivers by riprap requires large blocks with weights typically exceeding 1 t. Thus, the blocks have to be placed individually. Such packed riprap has a relatively small spacing between the blocks. Consequently, the ...

Design optimization of permeable sediment traps for fluvial bed load transport

Anton Schleiss, Mona Jafarnejad Chaghooshi, Sebastian Schwindt, Anita Hélène Roth

Sediment traps are crucial elements for flood protection in mountain rivers with high sediment transport capacity. Existing structures often interrupt the channel connectivity. Ideally, a sediment trap should be permeable for bed load during non-hazardous ...

Time-based failure analysis of compressed riverbank riprap

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

Methods to design riprap-lined channels usually refer to dumped material. Large blocks placed individually by machinery are used when more stability is required. They offer additional resistance against flow erosion since space between blocks is minimized ...

Probabilistic failure analysis of riprap as riverbank protection under flood uncertainties

Eugen Brühwiler, Anton Schleiss, Mona Jafarnejad Chaghooshi, Michael Pfister

Existing riverbank riprap could face the risk of failure if the flood regime changes in future. Additionally, changed sediment transport in rivers, as a possible result of climate change, impacts the failure risk of flood protection measures. Evaluation of ...

Time-dependent failure analysis of large block size riprap as bank protection in mountain rivers

Mona Jafarnejad Chaghooshi

Erodible river banks need to be safe against the possible scouring during flood events in mountain rivers. The consequences of the bank failure are probably lateral uncontrolled erosion and flooding with disastrous losses in residential areas or damage of ...

Analysis of Ballast Transport in the Event of Overflowing of the Drainage System on High Speed Lines

Giovanni De Cesare, Tamara Ghilardi, Mona Jafarnejad Chaghooshi, Elena Battisacco

The transport of ballast caused by the overflowing of longitudinal drains is a prime example of the interactions between the railway track and its environment. In such conditions, water flowing from the platform, along with debris, may drag the ballast off ...

Effect of compressed riprap thickness on the stability of river banks

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

One of the common measures for river bank protection is the installation of riprap. There are several methods to design riprap appropriately, which are however generally limited to dumped medium size blocks. Nevertheless, an additional resistance against e ...

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 ...
