A rule-based modelling concept to simulate hydromorphological measures – a tool for the design of programmes of measures for the EU Water Framework Directive
نویسنده
چکیده
Hydromorphological deficits are of real concern regarding the goals of the European Water Framework Directive to reach a good ecological status. The effects of measures that change the morphological structure of a river is hard to predict. Existing methods to simulate this process in a traditional numerical model can not be applied to whole river systems. Using a rule-based modelling concept to find feasible measures and predict the impact of those measures is a very promising solution.

Reliability Measures Measurement under Rule-Based Fuzzy Logic Technique
In reliability theory, the reliability measures contend the very important and depreciative role for any system analysis. Measurement of reliability measures is not easy due to ambiguity and vagueness which exist within reliability parameters. It is also very difficult to incorporate a large amount of uncertainty in well-established methodologies and techniques. However, fuzzy logic provides an...
متن کاملDevelopment and application of the modelling system J2000-S for the EU-water framework directive
The scientific sound definition of measures to achieve the goals of the EU water framework directive (WFD) acquires spatially distributed analyses of the water and substance dynamics in mesoto macro-scale catchments. For this purpose, modelling tools or systems are needed which are robust and fast enough to be applied on such scales, but which are also able to simulate the impact of changes on ...

From 1991 onward, the European Union (EU) member states have had to comply with the Nitrates Directive. The aim of this directive is to sustainably protect ground and surface waters from pollution with nitrogen (nitrate) originating from agriculture. Agriculture is, on an EU level, the largest single source of nitrate (runoff, leaching) pollution, although households and industries also contrib...

The multiple protocols that have been developed to characterize river hydromorphology, partly in response to legislative drivers such as the European Union Water Framework Directive (EU WFD), make the comparison of results obtained in different countries challenging. Recent studies have analyzed the comparability of existing methods, with remote sensing based approaches being proposed as a pote...
