+# Nature-like fish passage with riprap in periodic rows
+
+It is stated on p.16 of the design guide for nature-like fishways
+(Larinier et al., 2006)[^passe_rangees_periodiques1] that rock-rigged fishways
+in periodic rows are similar to fish ladders, and their design criteria are identical to those of.
+
+It is therefore possible to use the various tools in the "[fish ladder](pab.md)" module
+module to design this type of device.
+In particular, the "[cloisons](cloisons.md)" tool can be used to enter the various
+dimensional characteristics of weirs (widths, overflow dimensions) and pseudo-basins
+pseudo-basins (length, width, mid-radius), which can be used to indirectly
+indirectly retrieve the sill height (\(p\)) and useful block height (\(k\)) parameters
+in the generated geometry table.
+Porosity (ratio between the free passage between the blocks and the total width
+width of the pseudo-wall) is not entered directly, but this parameter can be
+be deduced and examined elsewhere if necessary.
+
+According to this principle, each overhanging portion of the partition must be entered
+as an indentation or slot, as well as the dimension of the top of the blocks if the latter
+are flooded within the operating range of the device.
+In the case of notches, particular attention should be paid to the type of
+(thick or thin) in order to accurately reflect the conditions of flooding by the
+downstream of the weir.
+
+It is also possible to use the "[pre-dams](prebarrage.md)" tool (the equations
+implemented are the same as in the "[cloisons](cloisons.md)" tool),
+if the device is affected by complex feed modes,
+with, for example, overflows from the weir to different basins in the system
+(a less frequent case for a riprap pass in periodic rows).
+
+An example of a pass can be accessed directly via [this link](https://cassiopee.g-eau.fr/#/loadsession/app%2Fexamples%2Fpasse_rangees_periodiques.json).

+# Passe « naturelle » à enrochements en rangées périodiques
+
+Il est indiqué en p.16 du guide de conception des passes naturelles
+(Larinier et al., 2006)[^passe_rangees_periodiques1] que les passes en enrochements
+en rangées périodiques s’apparentent aux passes à bassins et leurs critères de
+conception sont identiques à ces dernières.
+
+Il est donc possible d’utiliser les différents outils du module « [passe à bassins](pab.md) »
+pour concevoir ce type de dispositif.
+Notamment, l’outil « [cloisons](cloisons.md) » permet de renseigner les différentes
+caractéristiques dimensionnelles des déversoirs (largeurs, cotes déversantes) et
+des pseudo-bassins (longueurs, largeurs, cote mi-radier), qui permettent de
+retrouver indirectement les paramètres hauteurs de seuils (\(p\)) et hauteurs utiles
+des blocs (\(k\)) dans le tableau de géométrie généré.
+La porosité (rapport entre le passage libre entre les blocs et la largeur totale
+de la pseudo-cloison) n’est pas renseignée directement, mais ce paramètre peut
+être déduit et examiné par ailleurs si besoin.
+
+Selon ce principe, chaque portion déversante de la cloison doit être renseignée
+en tant qu’échancrure ou fente, de même que la cote du sommet des blocs si ces
+derniers sont ennoyé sur la plage de fonctionnement du dispositif.
+Pour les échancrures, il convient de porter une attention particulière au type
+seuil (épais ou mince) afin de bien retranscrire les conditions d’ennoiement par
+l’aval du déversoir le cas échéant.
+
+Il est également possible d’utiliser l’outil « [pré-barrages](prebarrage.md) » (les équations
+implémentées sont les mêmes que dans l’outil « [cloisons](cloisons.md) »),
+si le dispositif est concerné par des modes alimentations complexes,
+avec par exemple des déversés du seuil vers différents bassins du dispositif
+(cas moins fréquent pour une passes en enrochements en rangées périodiques).

+Un exemple de passe est directement accessible via [ce lien](https://cassiopee.g-eau.fr/#/loadsession/app%2Fexamples%2Fpasse_rangees_periodiques.json).
