Climate change impacts on entrance processes of intermittently open/closed coastal lagoons in New South Wales, Australia. Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 242 – 246. Gold Coast, Australia, ISSN 0749.0208. Intermittently open/closed coastal lagoons are a relatively unique feature of the south-east Australian coastline, and NSW in particular. Future climate change is expected to modify a number of climate variables that define the physical and chemical structure and ecological behaviour of the NSW coastal lagoons. These climate variables include mean sea level, wave climate and rainfall behaviour (total depth and storm intensity). Entrance morphodynamic processes are particularly vulnerable to climate change. These processes, which describe the opening and closing cycle of these lagoons, are controlled by dominant coastal (wave and sea level) conditions and episodic catchment runoff events. The magnitude of entrance impacts will depend on the particular characteristics and location of individual lagoons. An increase in mean sea level is likely to move the entrance sand berm upward and landward. An increase in south-easterly waves will cause minor rotations in beach planform alignments with expected net erosion from southern ends of beaches and net accretion at northern ends. For lagoon entrances at the southern end of beaches, this will result in a net loss of sand from the entrance and a shortening of the entrance channel. For lagoon entrances at the northern end of beaches, this will result in a net growth of the entrance berm, possibly offsetting the recession resulting from mean sea level rise. Increased typical lagoon water levels behind the berm are also expected. Marine flood tide deltas may accrete vertically and more landward. A decrease in total rainfall depth is likely to retard the cycle of filling and draining, and reducing the frequency of entrance breakout for mostly closed lagoons. For mostly open lagoons, however, an increase in rainfall storm intensity may actually increase scour through the entrance, thus increasing the longevity of ocean connections.","PeriodicalId":51078,"journal":{"name":"Journal of Coastal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140365001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pressure from lakeside developments, re-occurring blue-green algal blooms, declining fisheries, sedimentation and infilling of the ocean entrance, has borne several decades of focussed studies and routine monitoring programs, along with a variety of engineering and management solutions. A recent review recommended that these disparate studies should be enhanced to formulate a coordinated monitoring network that could improve both spatial and temporal coverage, develop a capacity to trigger responsive investigations and was able to serve the needs of system management. Through a series of partnerships an integrated network was developed that comprises event and baseline monitoring of catchment loads, local meteorological forcing and an array of water quality sampling sites within the lakes system. A majority of these sites are incorporated with real-time telemetry that provides up to the minute information to stakeholders via a web-based information management system and vital operational status to technical system management.","PeriodicalId":51078,"journal":{"name":"Journal of Coastal Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140365207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wave group effects on breaker height on a uniform slope. Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 767 – 772. Gold Coast, Australia, ISSN 0749.0208 The maximum wave height that can be achieved during shoaling is of key importance in the design of coastal structures and the assessment of near shore currents and water levels. Previous investigations, upon which current design guidelines are based, have tended to focus on regular, monochromatic waves thereby neglecting group effects. Studies incorporating random wave testing include these group effects but may require prolonged testing periods to achieve the design condition. The shoaling transformations of wave groups as they progress into shallow water and break has been investigated in laboratory wave flume experiments. The water surface elevations were recorded by capacitance type wave probes. The type and position of breaking was recorded and video imaging used to observe wave kinematics during shoaling and breaking. Results show that the interaction of horizontal (intra-group) and vertical (depth-induced) energy fluxes plays a key role in the shoaling and breaking processes of the wave group. Notably, the evolutional stage of the wave group as it approaches a critical threshold depth facilitates the emergence of two distinct shoaling cases – an early shoaling case and a delayed shoaling case. These distinctive shoaling cases appear to cause significant variation in the wave breaking properties (breaker type and breaking position) and in the maximum depth limited wave heights (Hb/d) observed. In particular, the delayed shoaling case appeared to stabilise the wave groups, delaying breaking and yielding Hb/d ratios in excess of current design guidelines. These preliminary results indicate that current design guidelines based on monochromatic waves may underestimate the ‘worst case’ scenarios associated with wave groupiness with consequent implications for engineering design, coastal modelling and hazard mapping and planning.
