BRYAN, K. R. TAY, H. W, PILDITCH, C. A., LUNDQUIST, C. J. AND HUNT H. L. 2007. The Effects of Seagrass (Zostera muelleri) on Boundary-Layer Hydrodynamics in Whangapoua Estuary, New Zealand. Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 668 – 672. Gold Coast, Australia, ISSN 0749.0208 Seagrass beds (Zostera muelleri) form extensive (> 10 Ha) intertidal beds in New Zealand estuaries potentially altering particle and nutrient fluxes to sediments. The effects of seagrass (blade length 5-8 cm, shoot density ~60/0.01m 2 ) on boundary layer dynamics were investigated at a site exposed to both tidal currents (~20 cm/s) and small wind waves (significant height 2-10 cm) over four days providing a variety of wave-current combinations. Flow characteristics were determined using two ADVs: one fixed at 15 cm above the bed and the other at varying heights within and above the canopy. The vertical variation of currents in and at the edge of the patch and on bare sediment during different tidal stages was measured. The inertial dissipation method was used to characterise changes to dissipation rate caused by varying bed character and hydrodynamic conditions. Results show that Z. muelleri altered the shape of the current profile by extending the boundary layer upward. The presence of waves caused substantial differences within the patch, appearing to increase the bed roughness. Dissipation rates outside the patch increased with proximity to the bed, whereas within the patch, they increased with distance from the bed. Dissipation rates were also observed to be greater on the incoming tide, even when differences in mean current speeds between flood and ebb tide were accounted for. Although the sudden transition at the edges of the Z. muelleri canopy caused more variable boundary profiles, the shape of the current profiles at the edge of the patch were clearly different on the ebb and the flood tides.

ABSTRACT T EJADA , M., M ALVAREZ , G.C. and N AVAS , F., 2007. A New Environmental Indicator for Coastal Artificialisation and Resilience Mapping. Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 67 – 71. Gold Coast, Australia, ISSN 0749.0208 Scientists and managers have developed and improved coastal protection and sustainable development measures. However, analysis and diagnostic methods are less than satisfactory when coping with the true complexity of socio economic drivers in coastal areas. Mapping of land use and its temporal variability in the coastal lands enables a first order approximation to the analysis of artificialisation although it shows a snap shot of the situation. An indicator which compares the evolution of land uses over a significant time span in the evolution of a developed coast as well as its spatial behaviour is introduced in this paper. The method, applied on the highly developed coastlines of Torremolinos in Costa del Sol, southern Spain, involves (i) mapping of a series of photo interpreted land use coverage stretching over 40 years; (ii) the implementation of a new algorithm that identifies land use change and calculates distance of change in relation to shoreline across a 1 km. buffer fringe; and (iii) transposing land use variability by qualifying via the concept of resilience onto the mapped shoreline to enable cartographic output of the analysis. Results of the implementation of the method on the selected pilot site and timeframe illustrate a high capability to interpret resilience (beyond sole scientist’s perception). The process of artificialisation is quantified and represented on a map which helps locating areas of potential high and low resilience (as in capacity to recover) given the trends. This is illustrated by mapped results and a final resilience map that could be of use for future decision making in the context of coastal management of developed coasts.
ABSTRACT T EJADA , M., M ALVAREZ , G.C. and N AVAS , F., 2007.用于海岸人工化和复原力绘图的新环境指标。Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 67 - 71.在这一过程中,需要对海岸带和海岸带生态系统进行全面的评估。然而,在应对沿海地区社会经济驱动因素的真正复杂性时,分析和诊断方法并不尽如人意。绘制沿岸土地利用及其时间变化图可以对人为化分析进行一阶近似分析,尽管它显示的只是一瞬间的情况。本文介绍了一种指标,它可以比较已开发海岸在相当长的时间跨度内土地利用的演变及其空间行为。该方法应用于西班牙南部太阳海岸托雷莫利诺斯高度发达的海岸线,包括:(i) 绘制 40 多年来一系列土地利用覆盖范围的照片;(ii) 实施一种新算法,以识别土地利用的变化,并计算 1 公里缓冲边缘内与海岸线相关的变化距离;(iii) 通过复原力的概念,将土地利用的可变性按限定条件转移到绘制的海岸线上,以实现分析的制图输出。在选定的试点地点和时间范围内实施该方法的结果表明,解释复原力的能力很强(超出了单个科学家的认知范围)。人工化过程被量化并在地图上表示出来,这有助于根据趋势定位潜在的高复原力和低复原力(如恢复能力)区域。绘制的结果和最终的复原力地图说明了这一点,可用于未来发达海岸的沿海管理决策。

WILLIAMS, P. AND LEMCKERT, C., 2006. Beach Carrying Capacity: Has it been exceeded on the Gold Coast? Journal of Coastal Research, SI 50 (Proceedings of the 9 th International Coastal Symposium), 21 – 24. Gold Coast, Australia, ISSN 0749.0208. Australia has more than 70,000 kilometres of coastline, 7000 km of those in Queensland. The beach has long occupied a special place in the Australian identity. The beaches are not only important to the Australian people but they are also a highly valuable tourist resource and with the number of tourists visiting the Gold Coast steadily increasing each year, determining their carrying capacity is an essential factor for their effective use and management. This study explored the concept of social carrying capacity, as well as the way Gold Coast beaches are used by locals and visitors. For the social carrying capacity concepts, several user counts using beach web camera images and more than 160 personal interviews were conducted at four different Gold Coast beaches, exploring coastal perception and beach usage. Preliminary results have revealed details including that while the majority of people surveyed thought beach crowds were perfect in their current state, 79% of the remaining respondents indicated carrying capacity had already been exceeded; that is that with Gold Coast beaches were perceived as either over-crowded or that they could do with fewer people. Through the analysis of interviews with beach users during April, 2006 and previously with University students in 2005, this paper explores the perception of beach users, with the aim of creating an understanding of their behaviour and attitudes and liasing with them in future planning and management processes used by local councils.

Gold Coast, Australia, ISSN 0749.0208.澳大利亚黄金海岸,ISSN 0749.0208。澳大利亚拥有 7 万多公里的海岸线,其中 7000 公里位于昆士兰州。长期以来,海滩在澳大利亚人的身份认同中占据着特殊的地位。海滩不仅对澳大利亚人民非常重要,而且也是非常宝贵的旅游资源。随着黄金海岸的游客数量逐年稳步增长,确定海滩的承载能力是有效利用和管理海滩的一个重要因素。本研究探讨了社会承载能力的概念,以及当地人和游客使用黄金海岸海滩的方式。针对社会承载能力的概念,我们在四个不同的黄金海岸海滩利用海滩网络摄像头图像进行了多次用户统计,并进行了 160 多次个人访谈,以探索海岸感知和海滩使用情况。初步结果显示了一些细节,其中包括:虽然大多数受访者认为海滩目前的人流量是完美的,但其余 79% 的受访者表示已经超出了承载能力;也就是说,黄金海岸的海滩被认为过于拥挤,或者可以减少人流量。通过分析 2006 年 4 月对海滩使用者的访谈以及之前 2005 年对大学生的访谈,本文探讨了海滩使用者的看法,目的是了解他们的行为和态度,并在地方议会未来的规划和管理过程中与他们建立联系。

Scaling designs for mobile bed short wave experiments have been analysed using a suite of numerical models to test different sediment scaling configurations. The numerical simulations have revealed that geometrical sediment scaling gives similarity in the boundary layer flow but the sediment transport mode switches from bedload in the prototype to suspended-load in the model. This is due to the high relation of prototype to model sediment sizes. However, scaling to maintain the relative fall speed allows smaller sediment size relations and closer similarity in the dominant transport processes. A set of corrections have been proposed to minimise the scaling effects in sediment transport rates and bottom evolution.
利用一套数值模型对移动床短波实验的缩放设计进行了分析,以测试不同的沉积物缩放配置。数值模拟结果表明,几何沉积物缩放使边界层流动具有相似性,但沉积物输运模式从原型中的床载荷转换为模型中的悬浮载荷。这是因为原型与模型的沉积物大小关系很大。然而,通过缩放来保持相对下落速度,可使沉积物尺寸关系更小,主要输运过程更接近。提出了一套修正方法,以尽量减少沉积物运移速率和底部演变的比例效应。
