Reservoir

A reservoir (ˈrɛzərvwɑːr; from French réservoir ʁezɛʁvwaʁ) is an enlarged lake behind a dam. Such a dam may be either artificial, usually built to store fresh water, or it may be a natural formatio

Computer simulation

Computer simulation is the process of mathematical modelling, performed on a computer, which is designed to predict the behaviour of, or the outcome of, a real-world or physical system. The reliabi

Simulation

A simulation is the imitation of the operation of a real-world process or system over time. Simulations require the use of models; the model represents the key characteristics or behaviors of the se

Experimental investigations on plunge pool protection measures for Ilarion Dam in Greece

Azin Amini, Giovanni De Cesare, Anton Schleiss, Romain Nathan Hippolyte Merlin Van Mol

Ilarion Dam is a 130 m high earthfill dam at Aliakmon River in northern Greece. The dam was commissioned in 2010. It has two spillway tunnels with ski jumps at the outlets. The two spillways are designed to release a total discharge of 5'500 m3/s during the probable maximum flood (PMF). During the flood events in 2013 and 2015, where only one spillway was working, scour holes have formed inside the plunge pool and erosion was observed at its banks and further down the tailrace channel. After a series of preliminary numerical investigations on the hydrodynamic behavior of the plunging jets, a physical model was built to assess the stability of prims protection carpets mitigate further scour of the plunge pool.

Morphological evolution of the Rhone River in the Martigny bend

Azin Amini, Giovanni De Cesare, Najla Schaller, Samuel Luke Vorlet

Sustainable water management is a principal matter to ensure safety of waterways (Berga, 2016). In this framework, the correction of the Martigny bend is a priority measure of the 3rd Rhone River correction in Switzerland, which aims at increasing the flood protection in the region while ensuring sustainable conditions for the Rhone River (Arborino and Jordan, 2014). The project foresees widening the bed of the river to the regime width and lowering the bed in the bend (Saugy et al., 2022). A numerical model is built to represent the priority measure, in order to assess the impact of the project on the sediment transport capacity and the morphological evolution in the long term.

Three-Dimensional Numerical Modelling of Al-Salam Storm Water Pumping Station in Saudi Arabia

Azin Amini, Azad Koliji

The Al-Salam Pump Station will be constructed in the framework of Jeddah Storm water Masterplan (JSWM) in Saudi Arabia. The station discharges the incoming flow from the Al-Salam storm tunnel to the Red Sea. Its structure includes a circular deep wet well (22m diameter and 20m depth below the ground) equipped with six pumps, one weir feed channel (6 m length, 10m width) equipped with four pumps, two pumping channels and two gravity discharge channels. Simulations have been carried out using CFD numerical modelling (Flow-3D) to verify the hydrodynamic performance of such a structure. The hydraulic analysis focuses on aspects such as flow velocity fields and distribution, water elevations, shear stresses and vorticities. The numerical simulations allowed to verify the hydraulic operation and design/performance criteria. These criteria include the allowable freeboard, minimum shear stress to transport sand particles and organic materials, the critical submergence of pumps for different hydrological scenarios, and finally the pre-swirl angle of the pumps. Simulation results show uniform velocity distribution in the wet well as well as in the pumping channels and provide plausible information to confirm design criteria fulfilment.
