- The aquatic life in temporary stream reaches is strongly dependent on the temporal changes of the aquatic habitats, determined by the hydrological conditions. This axis is done within the multi-disciplinary consolidated research group FEHM (Freshwater Ecology and Management lab). This is providing the European River Basin Authorities and relevant stakeholders with advice and operational tools for sound implementation of the Water Framework Directive to this kind of water bodies.
(Left) FPD (Flow– Pools – Dry) plot showing the arrangement of the three main metrics that correspond to the three aquatic phases; flow permanence (Mf), Isolated pools permanence (Mp) and dry river permanence (Md). The arrows show the progression of every one of the three metrics whereas the axes show the values of every one of them. The central point represents a river that undergoes the three aquatic phases with the same frequency.(Right) Distribution of the TREHS aquatic phases regimes in the FPD plot. Qp: Quasiperennial; AF: Alternate-Fluent; FS: Fluent-Stagnant; St: Stagnant; AS: Alternate-Stagnant; Al: Alternate; Oc: Occasional; EP: Episodic. Mf: flow permanence; Mp: pool permanence; Md: dry channel permanence. The orange dots represent river stations were the metrics were obtained from in situ or photographic observations.
