First European Interlaboratory Ring Test Study to Detect DNA of Crayfish and the Crayfish Plague Pathogen From Water Samples

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
This European interlaboratory ring test highlights how methodological differences affect eDNA‐based detection of crayfish and the crayfish plague pathogen, emphasizing the need for harmonized protocols to improve reliability in conservation and disease monitoring efforts.

Beach profile variations under the action of irregular waves on submerged breakwaters [PDF]

open access: yes, 2012
During the onslaught of a storm on the coasts of Taiwan in summer and autumn, large waves and storm surge have often caused beach erosion. In order to mitigate coastal disasters and erosion, soft-options have been promoted in recent years, to fulfill the

Development of a Seawater Exchange Breakwater with a Water Chamber by Use of Wave Induced Vortex Flows [PDF]

open access: yes, 2007
We developed a new seawater exchange breakwater based on a curtain-wall type breakwater having double row curtain walls with different draft depth. It has a water chamber partly sheltered by a vertical curtain wall in front of a rear vertical wall and ...

Coast/breakwater-integrated OWC: A theoretical model [PDF]

open access: yes, 2019
Integrating wave energy converters into coastal structures such as breakwaters, seawalls or jetties not only offers benefits in terms of construction costs but also improves wave energy extraction.

Wave and Soil Pore-Pressure Transformation due to Submerged Porous Breakwater [PDF]

open access: yes, 2014
本研究旨在考慮海床為砂質底床,研究波浪通過透水性潛堤的波場特性與其所引致的砂質土壤孔隙壓力的變化。實驗中將六種不同高度與寬度變化之潛堤設置於水平砂質底床上,每種潛堤幾何佈置配合十六種不同週期及波高變化之波浪條件。主要量測項目為波高分佈及孔隙壓力變化。實驗結果顯示,當相對潛堤高度或相對堤頂寬度較大時,波浪反射率增加,堤後波高相對較低,透射率因此下降,故其能量損失較大,且波浪尖銳度亦與能量損失成正相關趨勢,但於相對潛堤高度較小時(h/d=0.5),改變潛提寬度及尖銳度其能損量差異性變小。研究中亦發現 ...

Depth-Averaged Non-Hydrostatic Hydrodynamic Model Using a New Multithreading Parallel Computing Method [PDF]

open access: yes, 2017
Compared to the hydrostatic hydrodynamic model, the non-hydrostatic hydrodynamic model can accurately simulate flows that feature vertical accelerations. The model’s low computational efficiency severely restricts its wider application.
