## Abstract The hyporheic zone (HZ) has the capability to eliminate and attenuate nutrients and contaminants in riverine systems. Biogeochemical reactions and the potential elimination of contaminants are strongly controlled by the flow paths and dynamics in the HZ. Nevertheless, an easily applicab

Streams in semi-arid regions, such as the south of Portugal, have highly seasonal flow regimes with a marked pattern of low or zero flow during summer and early autumn. As a result, throughout these months, most rivers have long dry reaches with occasional pools. The biotic communities have evolved
## Multistep enzymatic reactions take place when sulfated bile acids (SBAs) pass through an immobilized enzyme reactor. First, SBAs take place in the reaction of desulfation under catalytical action of a bile salt sulfatase immobilized in the reactor and formed 3b-hydroxyl bile acids. Formed 3b-hydr
