Natural Laboratory

The rapid recession of the shingle bank of Hurst Beach (up to 3.5m/yr) makes it an excellent natural laboratory for the study of the factors which influence the stability of shingle beaches. Studies have included: the significance of long period, high energy, swell waves - the classification and quantification of overwash processes - run-up and seepage characteristics - the effect of settlement of the underlying strata - and the implications for practices in shingle nourishment. The studies have revealed the distinctive character of shingle beaches as compared with the more fully researched sand beaches. More detailed research on shingle beaches is justified particularly in relation to (i) the run-up characteristics including its interaction with swash cusps and (ii) the influence of the subsidiary sand fraction on the beach characteristics.

This paper discusses the probability distributions of irregular wave run-up height and period on gentle slopes. Assuming that the long period component appeared on the run-up oscillation corresponds to the incident envelope wave period, a nonlinear model to estimate the probability distributions of run-up heights and periods is proposed. Laboratory experiments on gentle slopes of 1/15,1/30 and 1/40, and field measurements on a natural sandy beach with swash slopes of 1/6 to 1/14 were performed to examine the proposed model. The proposed model is shown to agree with the experiments.

Tsunami Run Up

This paper presents a methodology of estimating the inland incursion of tsunamis generated offshore by earthquakes by adapting prognostic equations of wind wave run-up to the earthquakes’ long-period characteristics. Tsunami height is estimated from site-specific historical events. The methodology takes account the nearshore depths, backshore topography, tidal range, and tsunami approach direction. Two project applications are discussed; one involving site development planning for a coastal resort whereas the other involving tsunami evacuation zone assessment for a prospective seaport site. Keywords: Tsunami, run-up, earthquake, planning, site development
