Native European flat oyster (Ostrea edulis) reefs have strongly declined in the Dutch Delta, motivating restoration efforts that use engineered substrates to support settlement and early reef development. In Lake Veere, Project Asta tests the Mother Reef concept: biodegradable clay blocks that are conditioned …

Biodiversity and water quality analysis was performed in the Bulurancang and Curah Tangkil springs present in mount Arjuno-Welirang. These values were correlated via the Pearson method. It was found that Bulurancang consistently showed higher species richness, diversity indices, and taxa in comparison …

Before finalizing the design plans for the Seawater Reverse Osmosis (SWRO) plant in Jubail, Saudi Arabia, requested by IDOM’s client, a flood risk analysis of the site is required. Within this flood risk analysis, the impacts on the SWRO site will be simulated during a rainfall event with a return period …

The restoration of native flat oyster (Ostrea edulis) reefs in Lake Veere is a key ecological goal of the Oyster Heaven project. However, successful reef development may be hindered by predation. The European green crab *(Carcinus maenas),* a known bivalve predator in Lake Veere. This study investigated …

In dit onderzoek wordt het verschil tussen een centrale en decentrale rioolwaterzuiveringsinstallatie onderzocht om inzicht te krijgen in de milieu-impact. Het onderzoek is uitgevoerd met behulp van het Greenhouse Gas-protocol dat drie scopes beschrijft om directe en indirecte broeikasgas emissies te …

Het doel van dit onderzoek was om statistisch een benadering te maken van de optimale bodembedekking voor tarbot in de raceways van Seafarm. Het is van belang dat de kweek duurzaam verloopt, zodat het welzijn van de tarbot niet verkeken wordt, maar er moet ook voldoende productie zijn dat de handel winstgevend …

Salt marshes are known to be an important habitat type for numerous species of fish. As fish stocks are pressured around the world, providing them with suitable habitat is very important. Through managed realignments or tidal restoration, intertidal salt marshes are created or restored. Which fish use …

De Japanse oesterboorder (Ocinebrellus inornatus) is een aquatische roofslak die zich voedt met de Japanse oester (Magallana gigas) als de Zeeuwse platte oester (Ostrea edulis). De oesterboorder boort door middel van zijn tong een gaatje in de schelp van de Japanse- en Zeeuwse platte oester en zuigt …

In the following thesis, research is conducted on the effect of sea-level rise and expected hydraulic load levels for the Scheldt Estuary, currently and in the future. As climate changes advances and the sea-level rises, insight into the effects of the rise on our coastal area's is essential. Rijkswaterstaat …

The turbidity in Lake Markermeer limits the primary production by phototrophic algae and the growth of plants. In turn, this limits the amount of fish and other organisms that live in and around Lake Markermeer in its food sources. To determine if there are organisms that limit the resuspension, a survey …
