"The measurement of susoended sediment, particularly in field settings, is important in the documentation of sediment transport and deposition. Many measurement techniques have been used euth varying degrees of success. "

"ABSTRAKThe stable pools formed by spur dikes can be a significant factor for improving aquatic habitat in unstable degraded streams. Prediction of the volume and geometry of the scour hole associated with a spur dike yields information that is valuable for assessing the potential benefit to the aquatic habitat. Volumes of the scour hole in the vicinity of model spur dikes were measured in a laboratory flume under clear-water overtopping flows. Spur dike length, flow depth and shear velocity ratio were varied in the experiments and found to significantly influence the volume of the scour hole. For overtopping flows, the ratio of the flow depth to the spur dike height was found to be an important control on the geometry of the resulting scour hole. At higher flow depth to spur dike height ratios, the location of the maximum depth of scour changed from the upstream point of the dike toward the channel bank and caused a secondary scour zone to form downstream of the spur dike. A preliminary technique is proposed to predict the volume of scour for spur dikes perpendicular to the bank."

"Surface dressing has been a popular maintenance alternative for many years. The inservice performance of surface dressing relates to balancing properties such as skid resistance against changes in time as the aggregate particles embed into the underlying road and react to trafficking. This paper summaries the development of predictive laboratory methods to better understand the inter-relationships between embedment and how performance characteristics such discussed. The findings of this laboratory based research appear to rank materials according to their in-service performance and should result in more sustainable use of limited high quality materials for road maintenance and construction purposes.
