  • A Study of Hydrodynamic and Coastal Geomorphic Processes in Küdema Bay, the Baltic Sea
    Coastal Engineering 187 A study of hydrodynamic and coastal geomorphic processes in Küdema Bay, the Baltic Sea Ü. Suursaar1, H. Tõnisson2, T. Kullas1, K. Orviku3, A. Kont2, R. Rivis2 & M. Otsmann1 1Estonian Marine Institute, University of Tartu, Estonia 2Instititute of Ecology, Tallinn Pedagogical University, Estonia 3Merin Ltd., Estonia Abstract The aim of the paper is to analyze relationships between hydrodynamic and geomorphic processes in a small bay in the West-Estonian Archipelago. The area consists of a Silurian limestone cliff exposed to storm activity, and a dependent accumulative distal spit consisting of gravel and pebble. Changes in shoreline position have been investigated on the basis of large-scale maps, aerial photographs, topographic surveys and field measurements using GPS. Waves and currents were investigated using a Recording Doppler Current Profiler RDCP-600 deployed into Küdema Bay in June 2004 and the rough hydrodynamic situation was simulated using hydrodynamic and wave models. The main hydrodynamic patterns were revealed and their dependences on different meteorological scenarios were analyzed. It was found that due to exposure to prevailing winds (and waves induced by the longest possible fetch for the location), the spit elongates with an average rate of 14 m/year. Major changes take place during storms. Vitalization of shore processes is anticipated due to ongoing changes in the regional wind climate above the Baltic Sea. Keywords: shoreline changes, currents, waves, sea level, hydrodynamic models. 1 Introduction Estonia has a relatively long and strongly indented shoreline (3794 km; Fig. 1), therefore the knowledge of coastal processes is of large importance for WIT Transactions on The Built Environment, Vol 78, © 2005 WIT Press www.witpress.com, ISSN 1743-3509 (on-line) 188 Coastal Engineering sustainable development and management of the coastal zone.

The Santa Rosalía basin is a NW-SE elongated fault-bounded depocenter that records the sedimentation from Upper Miocene to Pleistocene time. The sequence is divided in El Boleo, La Gloria, Infierno and Santa Rosalía Formations. The lower most stratigraphic unit is the El Boleo Formation, a 200 to 300 m thick section composed in its lower part by a 1 to 5 m thick basal limestone and gypsum bodies followed by 170 to 300 m of clastic coarsening upward fan-delta, marine and nonmarine deposits.

  • The Path of a Pebble- Coastal Processes Activities
    The path of a pebble Teachers notes Indulge your natural sense of exploration on the beach by collecting pebbles and recording sound effects. This activity uses the intuitive games that pupils and adults alike will want to play when exploring the beach for the first (or twentieth) time while helping to embed learning about abrasion, attrition, and other processes of coastal change. Location: Barton on Sea or any shingle or pebble beach Timing: 30-45 minutes Age: Key stage 2 Curriculum links: Maths- 3D shapes, volume, estimation, Geography- coastal processes and change Science- rock types and properties, forces. English- poetry, onomatopoeia. (* check tides, weather conditions and safety of access near actively eroding cliffs prior to visit, take throw rope and appropriate emergency numbers, clearly demarcate and explain which areas pupils can explore safely) Learning Outcomes: Estimate the volume of different beach materials and the energy need to move and lift them Discover that shingle is made from mixed materials (rock types, shells, man-made etc.) which have varying degrees of hardness. Understand that harder rocks erode softer rocks creating shingle and pebbles of varying sizes (attrition) Resources needed: Blank postcard sized plain card Coloured pencils Aerial photo of your coastal site from e.g. google earth in two different time periods. The path of a pebble- Teachers notes Part 1- Does the coast stay the same? From a high point, admire the view and point out landmarks (the Solent, Isle of Wight, Bournemouth).

  • Carbonate Platform Evolution: from a Bioconstructed Platform Margin to a Sand-Shoal System (Devonian, Guilin, South China)
    Sedimentology (2002) 49, 737–764 Carbonate platform evolution: from a bioconstructed platform margin to a sand-shoal system (Devonian, Guilin, South China) DAIZHAO CHEN*, MAURICE E. TUCKER , JINGQUAN ZHU* and MAOSHENG JIANG* *Institute of Geology and Geophysics, Chinese Academy of Sciences, PO Box 9825, Beijing 100029, China (E-mail: [email protected]) Department of Geological Sciences, University of Durham, Durham DH1 3LE, UK (E-mail: [email protected]) ABSTRACT The depositional organization and architecture of the middle–late Devonian Yangdi rimmed carbonate platform margin in the Guilin area of South China were related to oblique, extensional faulting in a strike-slip setting. The platform margin shows two main stages of construction in the late Givetian to Frasnian, with a bioconstructed margin evolving into a sand-shoal system. In the late Givetian, the platform margin was rimmed with microbial buildups composed mainly of cyanobacterial colonies (mostly Renalcis and Epiphyton). These grew upwards and produced an aggradational (locally slightly retrogradational) architecture with steep foreslope clinoforms. Three depositional sequences (S3–S5) are recognized in the upper Givetian strata, which are dominated by extensive microbialites. Metre-scale depositional cyclicity occurs in most facies associations, except in the platform-margin buildups and upper foreslope facies. In the latest Givetian (at the top of sequence S5), relative platform uplift (± subaerial exposure) and associated rapid basin subsidence (probably a block-tilting effect) caused large-scale platform collapse and slope erosion to give local scalloped embayments along the platform margin and the synchronous demise of microbial buildups. Subsequently, sand shoals and banks composed of ooids and peloids and, a little later, stromatoporoid buildups on the palaeohighs, developed along the platform margin, from which abundant loose sediment was transported downslope to form gravity-flow deposits.
