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.

Early sowing refers to sowing up to six weeks before the normal sowing season.ᅠ This allows for an earlier and quicker development of crops and of a root network that leads to soil protection.ᅠ The period in which the soil lies bare is shorter and,... more
Sacrifice associated to the use of available resources to one means instead of another (so that any economic cost is indeed an opportunity cost) or of following one course of action instead of the best available alternative. As applied to NWRM, it... more
The suppression of lateral constraints consists in removing some bank protection in order to enhance lateral connection of the river, diversifying flows (depth, substrate, speed), diversify habitats but also capping floods in the mainstream. -... more
Negative impacts connected with the actual or potential degradation of natural assets or environmental quality due to economic activities.
The cost per year of implementing a NWRM over its entire lifespan. EAC is used when comparing NWRMs of unequal lifespans. It is estimated through listing all capital expenditures and when they are incurred; calculating the net present value of... more

(either positive or negative). Third-party effect or welfare impact, which is both unilateral (i.e. one cannot decide neither whether to suffer it or not nor how much impact to bear), and non-compensated. In other words, an externality stemming from... more
