Dyke Safety and Inspection Workshop objectives are mainly to review the design and construction of dykes, examine the factors controlling the stability/safety of dykes, examine methods to mitigate dyke instability, review dyke instrumentation options, and examine dyke inspection guidelines. All workshops/courses are led by professional engineers with many years of consulting, teaching and modelling experience. MDH provides on-site training workshops for individual organizations and also invites clients to travel to our head office in Saskatoon, SK for private in-house training. If you are interested in attending a workshop and/or a short course on Dyke Safety and Inspection, please email us.
