Ecosystem-Based Design Rules for Sand Extraction Sites


This tool provides some first design rules how sand extraction sites can be ecologically enriched. These ecosystem-based design rules are based on ecological data and estimated bed shear stress values collected from a site in the North Sea and can be used to maximise sand yield, minimize the impacted surface area with a on beforehand known ecological response. Ecosystem-based design rules can play a role in the Marine Strategy Framework directive (MSFD) which are currently implemented by European states.
