“…Liew et al (2010) used 1 m Ikonos images of pre-tsunami, tsunami, and post-tsunami periods to show that coasts affected by tsunamis naturally rebuild to their former morphological states in areas with little anthropogenic activity. The results showed straight beaches rebuilding a few weeks after the tsunami, but recovery of barrier beaches and lagoons is much slower, enabling inland rivers and streams to directly discharge into the ocean.…”

Abstract. Hydrological data collection requires deployment of physical infrastructure like rain gauges, water level gauges, as well as use of expensive equipment like echo sounders. Many countries around the world have recorded a decrease in deployment of physical infrastructure for hydrological measurements; developing countries especially have less of this infrastructure and, where it exists, it is poorly maintained. Satellite remote sensing can bridge this gap, and has been applied by hydrologists over the years, with the earliest applications in water body and flood mapping. With the availability of more optical satellites with relatively low temporal resolutions globally, satellite data are commonly used for mapping of water bodies, testing of inundation models, precipitation monitoring, and mapping of flood extent. Use of satellite data to estimate hydrological parameters continues to increase due to use of better sensors, improvement in knowledge of and utilization of satellite data, and expansion of research topics. A review of applications of satellite remote sensing in surface water modelling, mapping and parameter estimation is presented, and its limitations for surface water applications are also discussed.

“…We assume that reshaping the barrier represents development towards an equilibrium defined as "stability of form" (Woodroffe, 2002: 32) during a relatively stable sea level after disturbances (EWE II-XII) manifested by cyclic carbonate sequences spanning a period of c. 1 ka. This is a long time given the fact that beaches of Sumatra and Thailand have reorganised only a few years after the Indian Ocean Tsunami of 2004 (IOT) (Choowong et al, 2009;Liew et al, 2010). Nevertheless, Kraus (2005: 171) describes barrier breachings, which did "not recover on the timescale of human lifetime" in case the event was so strong that the sediment was transported into deeper water-consider the narrow reef and steep offshore slope of Bonaire-where it was out of reach for longterm wave action.…”

Shoreline changes and high-energy wave impacts at the leeward coast of Bonaire (Netherlands Antilles)

et al. 2012

Supralittoral coarse-clast deposits along the shores of Bonaire (Netherlands Antilles) as well as increased hurricane frequency during the past decade testify to the major hazard of high-energy wave impacts in the southern Caribbean. Since deducing certain events from the subaerial coarse-clast record involves major uncertainties and historical reports are restricted to the past 500 years, we use a new set of vibracore and push core data (i) to contribute to a more reliable Holocene history of regional extreme-wave events and (ii) to evaluate their impact on shoreline evolution. Multi-proxy palaeoenvironmental analyses (XRF, XRD, grain size distribution, carbonate, LOI, microfossils) were carried out using nearshore sedimentary archives from the sheltered western (leeward) side of Bonaire and its small neighbour Klein Bonaire. In combination with 14 C-AMS age estimates the stratigraphy reflects a long-term coastal evolution controlled by relative sea level rise, longshore sediment transport, and short-term morphodynamic impulses by extreme wave action, all three of which may have significantly influenced the development of polyhaline lagoons and the demise of mangrove populations. Extreme wave events may be categorized into major episodic incidents (c. 3.6 ka [?] BP; 3.2-3.0 ka BP; 2.0-1.8 ka BP; post-1.3 ka [?] BP), which may correspond to tsunamis and periodic events recurring on the order of decades to centuries, which we interpret as severe tropical cyclones. Extreme wave events seem to control to a certain extent the formation of coastal ridges on Bonaire and, thus, to cause abrupt shifts in the long-term morphodynamic and ecological boundary conditions of the circumlittoral inland bays.

“…Esto es contrario a lo generalmente observado en áreas donde por efecto de un terremoto ocurre subducción costera, la que junto a los tsunamis resultantes producen erosión signifi cativa de playas arenosas, tal como lo observado en playas de Tailandia, Sumatra y Japón después de los terremotos de los años 2004 y 2011 (Choowong et al, 2009;Liew et al, 2010;Udo et al, 2012).…”

RESUMENDurante los años 2010 y 2011, estudiamos los efectos del levantamiento costero producto del terremoto del 27F sobre el paisaje físico y la macrofauna de playas arenosas, ubicadas frente a defensas costeras artifi ciales en la península de Arauco y alrededores. El ancho promedio de las playas durante el periodo posterior al 27F fue hasta 12,5 veces mayor que los anchos observados antes del terremoto y la pendiente de las playas levantadas disminuyó. En playas que tenían defensas costeras ubicadas cerca del nivel de marea alta, el espacio restaurado en los niveles superiores y medios del intermareal (previamente ocupados por murallas y revestimientos rocosos), fue rápidamente colonizado por crustáceos que habitan niveles intermareales similares en playas sin defensas costeras artifi ciales. Estudios llevados a cabo luego de la ocurrencia de grandes perturbaciones, son relevantes para aumentar el conocimiento sobre las interacciones entre fenómenos naturales de gran escala y la infraestructura costera artifi cial.Palabras clave: Playas de arena, macrofauna, levantamiento continental, centro-sur de Chile. ABSTRACTDuring 2010 and 2011, we studied the effects of the continental uplift that resulted from the earthquake of 27F on the physical landscape and the macrofauna of sandy beaches located in front of coastal armoring along Península de Arauco and nearby areas. The mean width of uplifted beaches during the period following 27F was up to 12,5 times higher than beach widths observed before the earthquake and the beach face slope of uplifted beaches decreased. At those beaches that had coastal armoring located closer to high tides before the earthquake, the restored upper and mid shore beach levels (previously occupied by seawalls and rocky revetments) were rapidly colonized by crustacean species, which typically inhabit at similar intertidal levels of unarmored beaches of Chile. Field samplings carried out promptly after large scale disturbances have occurred, are relevant to increase knowledge on the interaction between that natural phenomenon's and coastal artifi cial infrastructure.
