, La validation d'un modèle n'est pas seulement la comparaison entre les résultats simulés et observés. Dans les procédures de calage et de validation nous testons la cohérence du modèle mathématique et de la structure logique du code informatique. Dans cetteétape, nous vérifions si les hypothèses qui ontété faitesà partir de l'observation du monde 9, Conclusion Générale

, ? Les interactions existant parfois entre hydrologie etérosion nécessiteraient que l'on arriveà coupler ces deux phénomènes

, ? La fonction de connectivité, limitée au transfert de sédiments, nécessiterait d'êtré etendue au transfert d'eau, en recalculant les variables hydrologiques au même temps que les variables d'érosion, afin de pouvoir mieux représenter les processus de "filtrage

, ? Il serait nécessaire d'introduire d'autres fonctions de connectivité, pour représenter d'autres types d'aménagements
