Basisregistratie Ondergrond (BRO) actualisatie bodemkaart : Herkatering westelijk veengebied Waterschap Drents Overijsselse Delta

Folkert de Vries; water Alterra Soil; F. Brouwer; D.J.J. Walvoort

De bodemkaart onderscheidt allerlei bodemtypen met veenlagen ondiep in het profiel. Door oxidatie en klink neemt de veendikte geleidelijk af. Voor het beheer van veengebieden is het van belang om inzicht te hebben in de veendiktes. Dit onderzoek heeft geresulteerd in een veendiktekaart voor het westelijk veengebied in Waterschap Drents Overijsselse Delta en een geactualiseerde bodemkaart, schaal 1 : 50 000, van dit veengebied.
