Video-based Monitoring of an Artificial Beach Nourishment Project
Cao, Z.; Zhang, C.; Chi, S.; Zhuang, L., and Zheng, J., 2020. Video-based monitoring of an artificial beach nourishment project. In: Malvárez, G. and Navas, F. (eds.), Global Coastal Issues of 2020. Journal of Coastal Research, Special Issue No. 95, pp. 1037-1041. Coconut Creek (Florida), ISSN 0749-0208. This paper presents a case study on field observation of a new artificial beach nourishment project in Rizhao Coast, China. Using video-based monitoring technique combined with beach profile surveying, wave overtopping features prior to nourishment, shoreline change during the construction, and short-term post-fill morphological evolution of the artificial beach are observed and analyzed. Results show that wave overtopping characteristics and nourishing process can be quantified through video imagery analysis. Two-month post-fill profile and shoreline data reveal that little sand has been moved to the deep water and overall sand volume above -6 m elevation remained stable. The northern beach evolution was dominated by alongshore sediment transport and the eroded sands from central beach were mainly transported to the north, while the southern beach evolution was affected by both alongshore and cross-shore processes due to sheltering effect of the southern breakwater. Attention is recommended to be paid to the relationship between overwash-driven onshore sediment transport and berm/backshore evolution, as well as the future evolution of beach morphology close to the northern breakwater. The present study suggests that integrating the video-based and the conventional monitoring approaches can be helpful to capture and interpret in more details the physical processes involved in different phases of a beach nourishment project.

Wave Runup Prediction and Alongshore Variability on a Pocket Gravel Beach under Fetch-Limited Wave Conditions
Most empirical equations used for wave runup predictions have been developed from measurements at straight sandy beaches in unlimited fetch environments. While there are empirical equations to predict wave runup on gravel beaches, they have not been tested for prediction of wave runup on pocket gravel beaches, in limited-fetch environment, which can be found around Mediterranean. This paper addresses this lack of measurements on this type of beaches and examines the alongshore variability of wave runup. Wave runup measurements were made using video observations along 3 cross-sectional profiles on the pocket beach of Ploče, Croatia. The measurements have shown that the wave runup can vary for about 71% even around the centerline of the pocket beach. This variability is due to beach orientation and alignment of beach profiles to the prevailing wave direction, as well as difference in beach slope. Comparison of wave runup predictions from five well-known empirical equations and field measurements showed significant underprediction (up to NBIAS = −0.33) for energetic wave events, and overall high scatter (up to NRMSE = 0.38). The best performing wave runup equation was used for further refinement outside the original parameter space by including the Goda wave peakedness parameter (Qp). The newly developed empirical equation for wave runup reduced the NBIAS to 0 and the NRMSE by 31% compared to the original equation (developed equation metrics: R = 0.91, NBIAS = 0, NRMSE = 0.2, HH = 0.2 on the study site). This empirical equation can potentially be used for design of coastal structures and artificial beaches in similar environments, but further measurements are needed to test its applicability to a range of forcing and environmental conditions.
