Scour and Erosion

AquaVision Engineering offers specific consulting in the field of scour and erosion at hydraulic  structures. Examples are scour formation in natural rock or plunge pools downstream of high-head  dams, or also erosion, abrasion and/or destruction of concrete linings of energy dissipation  structures such as stilling basins, spillway chutes, etc.  Dr E. Bollaert co-organized the International Workshop on Rock Scour at EPFL, Switzerland in 2002  and edited the work "Rock Scour due to High-Velocity Falling Jets", Swets & Zeitlinger, The  Netherlands.   He has almost 20 years of experience in scour and erosion at hydraulic structures and is the  developer of the Comprehensive Scour Model (CSM, 2002), a completely physically based  engineering model to estimate scour formation at dams and hydraulic structures.   One of the major advantages of this model compared to other engineering approaches is its  capability to predict scour formation as a function of time and intensity of flood events. The model  is applicable to any kind of fracturable medium, such as rock, clay, concrete, blockworks, etc.   SInce 2002, AquaVision Engineering has applied the CSM to several real-life scour problems  worldwide, mainly in the Middle East, United States, Australia and Europe. It may actually be  considered as the most advanced dam foundation scour model readily available for practical  engineering.   Beside scour at dams, we also offer services on scour and erosion of channels, bridge piers and  river banks.
