heal.abstract	Freshwater ecosystems are considered as one of the most vulnerable types of aquatic systems facing several natural and anthropogenic threats such as pollution, irrigation pressures and flow modification (e.g., dam constructions). These threats are more impactful in semi-arid and arid regions that are heavily impacted by climate change, with phenomena such as drought and desertification, there is a demanding need for research, in order to facilitate advanced biological and hydraulic simulation models to effectively estimate the potential impact of severe stressors. In the present work, we carried out ecohydraulic field measurements and simulations in two unexplored rivers (Oum Er Rbia; Ziz) located in central and east Morocco (North Africa). Initially, we collected field-based data through hydraulic and biological river sampling (benthic macroinvertebrates; BMs) upstream of a major dam in each river. As a result, region-specific Habitat Suitability Curves (HSCs) were produced through dedicated fitting algorithms based on the aquatic preferences of organisms. Afterwards, several ecohydraulic simulations were performed using real-time topographic/hydraulic field data in order to identify the optimal ecological and environmental flow for the examined aquatic biota in both regions. Finally, we proceeded with a comparative analysis between the produced HSCs and the ecohydraulic patterns of both sites, along with comparisons with research works applied in other Mediterranean regions.	en
