# Upstream / downstream elevations of a reach
This module is based on the equations of the [backwater curves module](courbe_remous.md) and is used to calculate the following:
- The water elevation upstream of a reach of a fluvial backwater curve;
- The water elevation downstream of a reach of a torrential backwater curve;
- The flow that connects the upstream and downstream water elevations of a fluvial or torrential backwater curve.
The regime chosen on the type of water line determines whether the calculation is made from downstream to upstream (fluvial regime) and from upstream to downstream (torrential regime).
This calculation module is particularly useful for calculating the water line of a series of hydraulic structures or reaches (see the typical example "Flow of a channel with structures").
# Cotes amont / aval d'un bief
Ce module basé sur les équations du [module de calcul des courbes de remous](courbe_remous.md) permet de calculer :
- La cote de l'eau à l'amont d'un bief d'une courbe de remous fluviale 
- La cote de l'eau à l'aval d'un bief d'une courbe de remous torrentielle 
- Le débit permettant de relié les cotes de l'eau amont et aval d'une courbe de remous fluviale ou torrentielle.
Le régime choisi sur le type de ligne d'eau détermine si le calcul s'effectue de l'aval vers l'amont (régime fluvial) et de l'amont vers l'aval (régime torrentiel).
Ce module de calcul est particulièrement utile pour calculer la ligne d'eau d'un enchaînement de ouvrages hydrauliques ou de biefs (Voir l'exemple type "Débit d'un chenal avec ouvrages").
