AquaVision Engineering offers specific consulting in the field of scour and erosion of 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 more than 10 years of experience in scour and erosion at hydraulic structures and is the developer of the Comprehensive Scour Model (CSM), a new and 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 of flooding. 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 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 our services on scour and erosion of channels, bridge piers and river banks. Dr J. Beck is the developer of the latest stream bank erosion model implemented in the CCHE1D numerical software developed at the National Centre for Computational Hydraulics (NCCHE) in Mississippi, United States.
