In de 90-jaren van de vorige eeuw is gestart met het natuurlijker inrichten van de Maasoevers (PNOM). In 2005 heeft dit programma een grote impuls gekregen door het project “NVO-Maas”. De aanleiding hiertoe was de ambitie om de ecologische kwaliteit van de Maas te verbeteren, wat mede ingegeven was door de Europese Kaderrichtlijn Water. Besloten is...

This abstract summarizes the outcomes of a 10 year monitoring project of biological and hydro-morphological parameters in the Dutch part of the Meuse river after partial removal of bank protection.

The EU FP 7 project MARS – “Managing Aquatic ecosystems and water Resources un- der multiple Stress” (duration 01.02.2014 – 31.01.2018) investigated how multiple human stressors affect rivers, lakes, groundwater, transitional and coastal waters. Outcomes of this research project are more than 200 scientific publications, more than 4000 pages of del...

This deliverable gives an overview of the functionality of the Freshwater Information System (FIS) through a number of screenshots and a short explanatory text. FIS is one of the tools that are developed within the MARS project. It is the web-based information system providing access to information and practical tools generated in MARS. FIS contain...

The Water Framework Directive (WFD) Explorer computes transport and decay of nutrient loads throughout a catchment (Roovaart et al, 2013; Burger et al, 2014). A typical WFD-Explorer schematization consists of a network of drainage basin and surface water nodes. Seasonal steady state simulations yield nutrient concentrations in each node as well as...

D6.1-1 Summary: Currently, practical management of water bodies focuses on the control of single stressors which are assumed to be dominant. Work by the MARS project and others using ecosystem scale and experimental observations has demonstrated that the relationships between primary stressors and ecological response indicators can be confounded th...

De maatregelen voor de Rijkswateren uit het BPRW-2 zijn doorgerekend op hun effecten voor het behalen van de doelstellingen van de Kaderrichtlijn Water. Hiervoor zijn de monitoringsdata van het MWTL-meetprogramma toebedeeld aan ecotopen en zijn EKR-scores berekend met de ecotopen-methode van de KRW-Verkenner. Aanvullend zijn voor alle Rijkswateren...

The International Meuse Commission (IMC) requested an ex-ante evaluation of the planned measures included in the River Basin Management Plans 2016-2021 of the EU Water Framework Directive to reduce total nitrogen emissions to the North Sea. The study allows more insight into the contributions of the different member states to the total nitrogen con...

De laagveenplas Terra Nova kampt al jaren met blauwalgenbloei en lage bedekkingen met waterplanten, ondanks jaarlijkse biomanipula%emaatregelen. Een belangrijke oorzaak hiervan is de fosfaatrijke waterbodem met een laag ijzergehalte, die zorgt voor een hoge fosfaatnalevering naar de waterlaag. Om het ijzergehalte van de bodem te verhogen, werd gele...

High internal phosphorus loading annually causes eutrophication problems in peat lakes resulting in poor biodiversity and algal blooms. To decrease phosphorus mobilization rates from the sediment to the water layer and to improve water quality, peat lake Terra Nova was gradually treated with FeCl₃ (33 g Fe/m 2 in 1½ years). In an isolated untreated...
