Linondation Les diffrents types dinondationLinondation est la consquence de plusieurs situations : le crues des rivires, la remonte de nappes phratiques ou les ruissellements urbains.

les crues des rivires sont dues une pluviomtrie importante, aggraves par la prsence dun tapis neigeux (fonte rapide) exemple janvier 2011 sur lOise amont: crue centennale)

Les inondations occasionnent souvent des dgts considrables et laissent les victimes dsempares.

Environ 16 000 communes sont concernes par le risque inondation en France.

Il existe plusieurs types dinondations : lente, rapide, trs rapide.

Les diffrents types dinondationLinondation lente (inondation de plaine)

Cest le dbordement dun cours deau ou la remonte de la nappe phratique qui est lorigine de la monte des eaux. Les inondations de plaine tant lentes sont rarement meurtrires mais, en raison de leur dure, elles ont des consquences lourdes sur les infrastructures, les biens, les activits conomiques et environnementales.

1er Cas :En temps normal, la rivire s'coule dans son lit mineur.Pour les petites crues, l'inondation s'tend dans le lit moyen et submerge les terres bordant la rivire.Lors des grandes crues, la rivire occupe la totalit de son lit majeur.Dbordement dun cours deau

Les diffrents types dinondationLinondation lente (inondation de plaine)

La remonte de la nappe phratique est due des pluies successives et prolonges saturant les sols et rechargeant les nappes jusqu atteindre la surface

2me cas :Remonte de la nappe phratique.

Lorsque le sol est satur d'eau, la nappe affleure et inonde les terrains bas.Remonte de la nappe phratique

Les diffrents types dinondationLinondation rapide (crue torrentielle)

En raison de limpermabilit des sols, les eaux de pluie envahissent les points bas transformant les rues en torrents. La quantit de matriaux charris par la crue peut dtruire btiments et infrastructures. Lorsquele dbordement du cours deau se combine des coules boueuses, cest dvastateur.

Des prcipitations intenses tombent sur tout un bassin versant, les eaux se concentrent rapidement dans le cours d'eau, d'o des crues brutales et violentes dans les torrents et les rivires torrentielles. Le lit du cours d'eau est en gnral rapidement colmat par le dpt de sdiments et des bois morts peuvent former des barrages, appels embcles. Lorsqu'ils viennent cder, ils librent une norme vague, qui peut tre mortelle.Crue torrentielle

Les diffrents types dinondationLinondation trs rapide (inondation urbaine)

Cause par des pisodes orageux violents sur de petits bassins versants, limpermabilisation du sol favorise ce type dinondation. En raison de limpermabilit des sols, les eaux de pluie envahissent les points bas transformant les rues en torrents. La quantit de matriaux charris par la crue peut dtruire btiments et infrastructures.

L'impermabilisation du sol (btiments, voiries, parkings, etc.) limite l'infiltration des pluies et accentue le ruissellement, ce qui occasionne souvent la saturation et le refoulement des rseaux d'assainissement et des eaux pluviales. Il en rsulte des coulements plus ou moins -importants et souvent rapides dans les rues.Inondation par ruissellement
