In het late voorjaar worden de eerste oesterlarven in het water waargenomen. Oesterlarven brengen gemiddeld 6-13 dagen (platteoesters) tot 21 dagen (Creuse oesters) in de waterkolom door voordat ze zich vestigen op hard substraat. Binnen dit project is er drie jaar rond de voortplantingsperiode invangmateriaal …

Om Creuse en platte oesters te kunnen kweken zijn jonge oesters ('oesterbroed') nodig. Oesterbroed wordt verkregen door het invangen van oesterlarven. Traditioneel leggen oesterkwekers hiervoor lege mosselschelpen op de bodem van hun percelen. Er worden ook proeven gedaan met invangmateriaal dat vrij …

Anthropogenic changes to estuaries, usually highly productive systems, may result in increased turbidity levels, suppress pelagic primary production and negatively affect ecosystem functions. The Ems-Dollard estuary, enclosed between the Netherlands and Germany, is such an estuary with a long history …

Light is a form of energy produced by a luminous object which occurs as electromagnetic radiation and is closely related to other forms like radio waves, microwaves, gamma rays, infrared, UV and X radiation. The different kinds of radiation can be classified by using wavelengths. Only a small section …

Seminar at Lille University, 2 February 2023 The main objectives of the living lab Hedwige-Prosperpolder are: - Build capacity to cope with the adverse effects of climate change - Advance and share knowledge on the design and maintenance of levees - Advance and share knowledge and experiences in flood …

Seaweed-based solutions can offer a valuable contribution in addressing today’s challenges such as climate change, food availability and finding alternatives to fossil-based value chains. To achieve this, the European seaweed sector needs to scale-up, and devise smart solutions to make the production …

Het project ZEEMOS is zijn derde en laatste jaar ingegaan.

ZEEMOS richt zich op de combinatie …

Floating photovoltaics (FPV) is emerging as a promising renewable energy technology which enables the production of electricity on surface waters. While this technology could potentially make an important contribution to the energy transition, the current uncertainty about the water quality effects of …

This report bundles the annexes for the data report of the overflow tests executed on the Dutch part of the Hedwige-Propserpolder levees. Overflow tests on levees are designed to test the strength of levees and levee covers under the load of a continuously overflowing discharge of water. For this purpose, …

Report on testing of water overflow on Dutch levees. On the Dutch part of the levee in Hedwige-Prosperpolder, 11 overflow tests have been conducted. Overflow tests on levees are designed to test the strength of levees and levee covers under the load of a continuously overflowing discharge of water. …
