WAMSI 2 - Dredging Node - 3.3 - Transport Processes (Field)

This sub-project 'Transport Processes' - Project 3.3 aims to build on ‘conventional’ knowledge and formulations of sediment transport over open (bare) sandy beds, to develop new transport formulations applicable to a broad range of bottom types.

The objectives of sub-project 3.3 (Field) are therefore to;
1) Develop new fundamental empirical relationships of sediment deposition and erosion rates applicable to a range of habitat types (e.g. coral reefs, seagrasses, etc.) as function of local hydrodynamics (waves and currents), physical properties of the sediment and bottom roughness/canopy characteristics.
2) Provide direct field measures of sediment fluxes, settlement and resuspension rates (both natural and dredge-generated) under real hydrodynamic forcing (3-week field study from 27 July–14 August 2013).
3) Incorporate new sediment transport routines applicable to a range of habitat types (developed in (1) and (2), within a community (open source) hydrodynamic and sediment transport model such as Delft3D or ROMS. In the future this new module could then easily be incorporated into any existing model.

本3.3号子项目“输运过程”以开阔（裸露）沙质海床的泥沙输运传统认知与既有公式为基础，旨在开发适用于多种底床类型的新型泥沙输运公式。

因此，3.3号实地子项目的目标如下：
1) 建立适用于多种生境类型（如珊瑚礁、海草床等）的沉积物沉积与侵蚀速率的基础经验关系式，该关系式以局地水动力条件（波浪与流场）、沉积物物理属性以及底床粗糙度/冠层特征为驱动变量。
2) 在真实水动力强迫条件下，获取沉积物通量、沉降与再悬浮速率（涵盖自然成因与疏浚成因两类）的直接实地观测数据，本次实地研究周期为2013年7月27日至8月14日，共计3周。
3) 将基于前两项任务开发的、适用于多种生境类型的新型泥沙输运程序，集成至Delft3D、ROMS等社区开源水动力与泥沙输运模型中。未来该新型模块可便捷地集成至任意现有模型之中。
