Working on NWRM requires understanding of a broad range of key concepts. This page gathers definitions for a set of key concepts used when addressing NWRM. It sets a shared ontology, with interlinkages between concepts. Semantic annotations have been developed and the associated ontology represented thanks to a relation graph.

Semantic Annotation helps to bridge the ambiguity of the natural language when expressing notions and their computational representation in a formal language. By telling a computer how data items are related and how these relations can be evaluated automatically, it becomes possible to process complex filter and search operations.

In the past, various activities were undertaken to straighten rivers, such as the stabilisation of river banks with concrete or other types of retention walls.ᅠ Such actions limited riversメ natural movements, leading to degradation of the river,... more
Natural Water Retention Measures (NWRM) are multi-functional measures that aim to protect and manage water resources and address water-related challenges by restoring or maintaining ecosystems as well as natural features and characteristics of water... more
Nature-based solutions aim to help societies address a variety of environmental, social and economic challenges in sustainable ways. They are actions which are inspired by, supported by or copied from nature. Some involve using and enhancing... more
Nitrate, NO-3, is the main nitrogen containing anion occurring in the soil. It is very soluble and moves freely in water through the soil profile. Nitrate in water is a pollutant above certain concentrations and can be a danger to human health. The... more
The 1980 EC Drinking Water Directive set a maximum of 50 mg/l of nitrate in drinking water (equivalent to 11.3 mg/l nitrate-nitrogen). An increasing number of water sources currently exceed this limit. Agriculture is the main source of nitrate in... more
Tillage is a mechanical modification of the soil.ᅠ Intensive tillage can disturb the soil structure, thus increasing erosion, decreasing water retention capacity, reducing soil organic matter through the compaction and transformation of pores. No-... more
