Reference excerpt

In France, the schéma directeur d'aménagement et de gestion des eaux (SDAGE) is a document that aims to put into effect the principles of the law of 3 January 1992 on the level of the major hydrographic basins. In translation, its name is outline for the organization of the development and management of water resources.

Rationale Water is a part of the nation's common heritage. Its protection, exploitation and setting into a usable state while respecting natural balances, is of general interest. The use of water belongs to all, within the framework of laws and regulations as well as of rights already established.

The law The main subjects addressed by the SDAGE are written into the law:

preservation of aquatic ecosystems, their sites and wetlands, protection against any pollution and restoration of the quality of the water, development and protection of the resource as drinking water exploitation of water as an economic resource and sharing that resource. The SDAGE scheme was drawn up together by the national, regional and département governments and is managed by the agence de l'eau (water agency).

How it works The SDAGE serves as a general framework for the development and management of the water of each hydrographic unit, system or aquifer). These are the schémas d'aménagement et de gestion des eaux (SAGE), that is water resource development and management outlines. The aquifer and the hydro-electric and recreational uses of water in the Ain valley compose a clear example of a site where a coordinated approach could be productive. However, the schéma is flexible enough to include specific needs as for example, that of Artois-Picardy, which is concerned specifically with the former mining basin of the Nord and Pas-de-Calais départements and the consequences of past and current exploitation of the région's coal.

Worked examples

Example 1 — a first encounter with Schéma directeur d'aménagement et de gestion des eaux

Start with the simplest possible case. Write down what Schéma directeur d'aménagement et de gestion des eaux claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Schéma directeur d'aménagement et de gestion des eaux before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Schéma directeur d'aménagement et de gestion des eaux ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Schéma directeur d'aménagement et de gestion des eaux

In research: Schéma directeur d'aménagement et de gestion des eaux appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Schéma directeur d'aménagement et de gestion des eaux in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Schéma directeur d'aménagement et de gestion des eaux is common in secondary-school and first-year university syllabi. It links to neighbouring topics Law of France, Water in France, Water law, so understanding it makes those chapters shorter.
In everyday life: Look for Schéma directeur d'aménagement et de gestion des eaux outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
