The Western Dredging Association (WEDA) is proud to offer a continuing education short course at the 2017 Dredging Summit & Expo. The course will be held at the Hyatt Regency Vancouver on Monday June 26, 2017 at 10 AM to 3 PM with a break for lunch on your own from 12 to 1 PM. For your participation in teh course, you will receive a certificate for 4 professional development hours (PDH’s).

Short Course Title: “Slurry Transport (updated with the latest develepoments)”
Date: June 26, 2017
Preface: In August 2012, Sape Miedema was approached by a dredging company with the question which head loss model to use for a project with a cutter dredge and a discharge length of 35 km. This raised the following questions:
These questions triggered a study in to the existing head loss models. With the knowledge that the main Dutch and Belgium dredging contractors use the Durand & Condolios (1952) and Fuhrboter (1961) models in a modified form, while companies in the USA and Canada often use the Wilson (1992) model in a modified form or the SRC model, the study started with a comparison of these models. Other models that were investigated were the Newitt et al. (1955) model, the Doron & Barnea (1987) model, the Matousek (1997) model and others. Also later models like the 4 component Sellgren & Wilson (2012) model and the 2LM and 3LM models of Wilson (1979-2014) and Matousek (1997-2014) were investigated.
Usually the models perform well in the neighborhood of the parameters used during the experiments, especially the pipe diameter (small) and the particle diameter, but for real life conditions (large pipe diameters) the models deviate and it’s not clear which model matches these conditions. Another issue is that most models are derived for transport (delivered) volumetric concentrations as input and not the spatial volumetric concentrations. The research into the existing models did not give a satisfactory result to the above questions.
Reason to develop a new model from scratch, the Delft Head Loss & Limit Deposit Velocity Framework. This DHLLDV Framework is based on the spatial volumetric concentration in the pipe and uniform sands or gravels and consists of a framework containing a set of sub-models.

Short Course Title: “The Big Hug and The Bottom Line: A Model for Safety Culture Change that Drives Operational Excellence“
Date: June 26, 2017
Short Course Description: This workshop is designed to actively engage participants in sharpening their mind sets, skill sets, and tool sets for affecting powerful and sustainable safety culture change within their organizations. In addition to working safety challenges specific to each participant’s organization, the session will also consider the idea of how powerful it could be if all dredging and marine construction companies joined us in raising the bar on safety.
Following this workshop, participants will be able to:
