Approach研究理念
A coastline is a moving sediment system, not a fixed line.海岸不是一條固定的線,而是一個動態土砂系統。
Shoreline advance and retreat result from the long-term action of waves, tides, longshore drift, river sediment supply and man-made structures. Any local intervention can shift the sediment balance, so protection is planned for the coastal system as a whole rather than for a single line on a map.
Field monitoring and numerical modelling of nearshore waves, longshore sediment transport and river sediment supply, used to quantify erosion and accretion and explain why a shoreline advances or retreats.以現場監測與數值模擬分析近岸波浪、沿岸漂砂與河川供砂,量化海岸侵淤量體,並解析灘線前進與後退的機制。

Summer monsoon. Waves from W and WSW reach the Nangang and Xiangshan segments directly; nearshore wave height is about 0.55 m. The Touqian River mouth is sheltered by the fishery-harbor breakwater, so waves there are smaller.
Winter monsoon. Larger waves spread over the area north of the harbor, the Nangang segment and offshore of Haishan Fishery Harbor. The very mild offshore slope at Xiangshan refracts incoming waves.
Sediment budget. Volumes by coastal cell were computed from surveys between April 2019 and June 2024. The intertidal beach widened after sand was placed south of the harbor.

North-facing shorelines on protruding headlands receive the most wave energy. On the north side of a bay, waves arrive normal to the shore for longer, so the hazard is higher than on the south side.突出岬頭面向北側之岸線受海洋營力影響最大;灣澳北側波浪垂直入射時間較長、危險度較高,南側則較低。

Fig. C1Coastal erosion risk by village, Yunlin coast.雲林海岸各村里海岸侵蝕災害風險。
Erosion-hotspot villages (Wengang, Hefeng, Yongfeng, Wugang, Lunnan, Guanggou, Gangxi) are mostly low to medium risk. Yongfeng is very low because its early-warning system is better than its neighbours'.侵蝕熱點岸段村里(蚊港、和豐、永豐、五港、崙南、廣溝、港西)多為中低風險;永豐村因預警制度較鄰近村里完善,為極低度風險。
Bodong village is rated medium risk and has the highest erosion-risk score on the Yunlin coast, although it currently shows no erosion potential. The drivers are a narrow wave-buffer zone, higher population density and activity, and weaker early warning.箔東村為中度風險,係雲林濱海陸地海岸侵蝕災害風險值最高之村里,目前尚無侵蝕潛勢;主因為消波緩衝帶寬度風險值較高、人口密度與活動頻繁程度較高、預警能力較弱。

Fig. C2Bed-level change between June 2019 and December 2023, with shoreline profiles by transect.2019 年 6 月至 2023 年 12 月地形變化與各斷面灘線變化。
Beibin seawall (nourishment): beach erosion where no artificial sand is supplied; nearshore accretion from offshore transport.北濱海堤(養灘):灘地侵蝕(無人工砂源補償);近岸海域淤積(離岸輸砂)。
Nanbin seawall (submerged breakwater): accretion behind the breakwater, erosion in front of it. Waves break early and the water behind is calmer.南濱海堤(潛堤):潛堤後側淤積、前方侵蝕(波浪提前碎波,後方海域靜穩)。
Huaren seawall (submerged breakwater): sand builds up to the breakwater and broken waves scour the shoreline, so the beach erodes while the nearshore accretes.化仁海堤(潛堤):砂灘淤至潛堤、碎波沖刷灘線,灘地侵蝕;近岸海域淤積。
Huaren revetment: the largest changes, driven by sediment from the adjacent Hualien River mouth. Across this sediment cell, both the shoreline and the nearshore zone show net accretion.化仁海岸保護工:緊鄰花蓮溪口,受河川輸砂影響,侵淤變化較顯著。整體輸砂單元之灘線及近岸海域皆呈淤積。

Protect: review and upgrade existing hard structures, which remain necessary here, using ecological and hybrid protection methods that meet the design standard.保護:既有混凝土硬式設施不可少,檢討、調整與改善現有結構物,採用符合防護標準之生態、複合型海岸保護工法。
Accommodate: adjust building types, land use and livelihoods to the hazard risk, and strengthen early warning and emergency response.適應:視災害潛勢導入新的建築型態、土地利用及生產經營方式,並加強災害預警與應變機制。
Retreat: avoid or relocate when impacts exceed what protection standards and adaptation can handle.後撤:當外在衝擊超過防護標準及適應策略所能因應時,以規避、退讓方式避免損失。
Dunes as sand reserve: constructed dunes supply sand and absorb wave attack, following nature-based-solution principles. Framework: first review of Taiwan's Integrated Coastal Management Plan.砂丘工法:作為砂源補注,防治侵蝕並降低浪襲衝擊,符合 NbS 規劃原則。依據整體海岸管理計畫第一次通盤檢討之調適策略。

Sand-dune and sandbar restoration field trials沙丘、沙洲復育工法現地試驗
34 of Taiwan's 82 wetlands of national importance lie on the coast, covering about 49,000 ha, or 70% of their total area. Dunes and sandbars shield these wetlands from offshore waves. Commissioned by the WRA Water Resources Planning Institute, the lab tested restoration methods on the Tainan coast and transferred them to agencies through site demonstrations. The work is cited in the UN guide Options for Ecosystem-based Adaptation in Coastal Environments.國內 82 處國家重要濕地中,位於海岸地區者計 34 處,面積約 4 萬 9 千公頃,佔總面積 70%。沙丘與沙洲是海岸濕地抵禦外海風浪的天然屏障。研究室受水利署水利規劃試驗所委託進行「海岸沙丘沙洲復育規劃」,以臺南海岸為案例進行現場復育工法試驗,並辦理現場觀摩與技術移轉;研究論文獲聯合國《以生態為本之海岸環境調適策略-操作手冊》引用。
