The analysis was conducted at two temporal scales: monthly and interannual, to investigate the controlling factors in the formation of washover fans within the sand spit barrier (2017–2023) and interdecadal, to understand the morphological behavior of the shoreline and the coastal system (1938–2021). The methodology involved the integration of remote sensing data, aerial photographs, tide gauge records, ocean-climatological data, and analyses of morphometric indicators. The study area was divided into five sectors based on foredune segmentation and the areas with the highest recurrence of overwash fan events. A total of 93 overwash events were identified, with a higher concentration during the autumn and winter months. The formation of washover fans was associated with a combination of storm surges, storm waves, and the presence of foredunes on the sand spit barrier during the passage of low-pressure centers (cyclones). Sectors 3, 4, and 5 exhibited greater vulnerability to overwash events, while Sector 1 was more affected by anthropogenic activities. On the interdecadal scale, the shoreline presented three evolutionary phases: a regressive phase (1938–1978), followed by two transgressive phases (1978–2005 and 2005–2021), with an intensification of the coastal system retreat after 2005. This study contributes to the understanding of how the high frequency of overwash events has driven a transgressive behavior across most of the Araranguá coastal system over the past 16 years, contrasting with the regressive pattern observed in the Holocene system as a whole.","本研究评估了越浪冲刷过程对巴西南部圣卡塔琳娜州海岸系统动态的影响。分析在两个时间尺度上进行：月际和年际尺度，以探究沙嘴沙坝（2017—2023年）内越浪扇形成的控制因素；以及年代际尺度，以理解海岸线及海岸系统的形态演变行为（1938—2021年）。研究方法整合了遥感数据、航空照片、潮位计记录、海洋气候学数据以及地貌形态指标分析。研究区域根据前丘分段和越浪扇事件高发区域划分为五个区段。共识别出93次越浪事件，主要集中在秋季和冬季月份。越浪扇的形成与风暴增水、风暴浪以及低压中心（气旋）过境期间沙嘴沙坝上前丘的存在共同相关。第3、4、5区段对越浪事件表现出更高的脆弱性，而第1区段则更多受到人为活动的影响。在年代际尺度上，海岸线呈现三个演化阶段：海退阶段（1938—1978年），随后是两个海侵阶段（1978—2005年和2005—2021年），其中2005年之后海岸系统后退加剧。本研究有助于理解越浪事件的高频发生如何驱动了阿拉兰瓜海岸系统大部分区域在过去16年间呈现海侵行为，这与全新世系统整体所表现出的海退格局形成鲜明对比。",null,"Natural Hazards","2026-09-06T00:00:00Z","论文",10,false,0,{"impact":15,"substance":15,"depth":15,"authority":15,"freshness":15,"relevant":15,"comment":17},"研究巴西海岸沙坝的越浪过程，与三农、农业信息化等主题无关。",[19],{"name":10,"url":6},[21],"海岸系统",[],{"status":24,"locked":14,"version":25,"method":26,"evidence":27},"needs_review","2026-10-22.2","rules",{"candidates":28,"agricultural_evidence":14,"reason":45},[29,38],{"code":30,"score":31,"supported":32,"title":33,"abstract":34,"tags":37},"I3",6,true,[],[35,36],"遥感","remote sensing",[],{"code":39,"score":40,"supported":32,"title":41,"abstract":42,"tags":44},"I7",3,[],[43],"研究方法",[],"农业相关性需要复核",[],"Overwashprocesses:spatio-temporalscalesa-1904","10.1007\u002Fs11069-026-08399-w",{"doi":48,"openalex_id":50,"authors":51,"venue":10,"cited_by_count":15,"oa_url":64,"card":65,"direction":69,"ingested_from":71},"W7210276993",[52,55,58,61],{"name":53,"orcid":54},"Edvan Casagrande dos Santos","https:\u002F\u002Forcid.org\u002F0000-0001-8008-2509",{"name":56,"orcid":57},"Viviane Vaz Medina","https:\u002F\u002Forcid.org\u002F0009-0000-2638-4661",{"name":59,"orcid":60},"Samanta da Costa Cristiano","https:\u002F\u002Forcid.org\u002F0000-0002-4368-7602",{"name":62,"orcid":63},"Maria Luiza Corrêa da Câmara Rosa","https:\u002F\u002Forcid.org\u002F0000-0002-1963-4842","https:\u002F\u002Flink.springer.com\u002Fcontent\u002Fpdf\u002F10.1007\u002Fs11069-026-08399-w.pdf",{"tldr":66,"method":67,"finding":68,"direction":69,"opportunity":70},"研究巴西圣卡塔琳娜南部沙坝障壁岛上的越浪沉积过程，分析其时空尺度与海岸系统动态。","集成遥感、航拍、潮位、海洋气候数据及地貌指标，分月、年际和年代际尺度分析。","93次越浪事件多发生在秋冬，与风暴潮、波浪和低气压有关；2005年后海岸系统退缩加剧。","农业遥感与作物表型","可借鉴其多尺度遥感与气候数据集成方法，研究海岸带农业用地对极端事件的响应与适应策略。","openalex","2026-09-08T23:30:19.187768Z",{"total":15,"page":74,"page_size":74,"items":75},1,[]]
