The objectives of this research are to better understand, describe and quantify the development of bedforms and hydraulic roughness under intense, non-equlibrium sediment loading.  This is a topic that has received little research attention, and has immediate practical application to the lower Fraser River design flood profile.  It is anticipated that this research will yield quantitative relations that can be used to estimate bedform type and roughness under design flow conditions on the Fraser River, which will result in improved confidence in the computed flood levels.

本研究的目的是更好地理解、描述和量化强非均匀泥沙负荷下的底形和水力粗糙度的发展。这是一个很少受到研究关注的主题，并立即实际应用于较低的弗雷泽河设计洪水剖面。预计这项研究将产生定量关系，可用于估计底形类型，在弗雷泽河的设计流量条件下的粗糙度，这将导致在计算洪水位的信心提高。
