The monitoring of river discharge is vital for the correct management water resources. Flat-V gauging weirs are facilities used worldwide measuring discharge. These structures consist a small weir with triangular cross-section and flat “V”-shaped notch. Their extensive use consequence their utility in measurement both low high flow conditions. However, depending on size, local morphology can ac...

Most freshwater fish need to move freely through rivers complete their life cycles. Thus, river barriers (e.g. dams, culverts and gauging stations) may delay, hinder or even block longitudinal movements, affecting conservation. The most widespread solution allow upstream migration are fishways, whereas downstream is basically facilitated spillways, turbines specific solutions such as bypass sys...

Pseudunio marocanus (Pallary, 1918) is an endemic species of Morocco and considered one the world’s 100 most threatened species. The life cycle this critically endangered freshwater mussel remains unknown. However, knowledge about discharge period its larvae ecological fish hosts crucial to adopt more effective conservation strategies. Given information gap, monitoring presence P. glochidia in ...

The Guadalquivir River Basin is one of the largest in Iberian Peninsula and has a remarkable freshwater biodiversity. Although many studies on hydrological regimes or water quality have been conducted this basin biodiversity fish, as well their distribution conservation status, never globally addressed other basins. In context, we synthesized information fish using field procedures bibliographi...
