Numerical & experimental investigation on the effect of scour formation and protection on the monopiles behavior

Offshore wind farms are rapidly developing in Western Europe as an alternative means of clean energy. The foundation of wind-turbines in the shallow water of the Northern Sea is almost exclusively (over 87%) performed by short rigid monopiles, as an efficient and relatively cheap solution. Scour formation, meaning the soil removal around the...

Numerical Investigation on the Effect of Scour Formation & Scour Protection on the Stiffness & Lateral Capacity of Monopiles

Wind turbines are nowadays the main means for producing renewable energy in Northern and Western Europe, and therefore research is conducted to secure their efficiency. One of the critical aspects of the windfarms is the foundation type, as it can define the functionality and the cost of each turbine. Monopiles have prevailed as the most...

Evaluating Scour at Bridges - Fifth Edition

This document is the fifth edition of HEC-18. It presents the state of knowledge and practice for the design, evaluation and inspection of bridges for scour. There are two companion documents, HEC-20 entitled "Stream Stability at Highway Structures", and HEC-23 entitled "Bridge Scour and Stream Instability Countermeasures". These three documents...
