## **3.1 Gathered data**

From the indicators collected data, a summary of 39 indicators with at least four mentions among the 76 articles selected are illustrated in **Table 1**.

## **3.2 Result remarks related to ecohydrology framework**

As it was alluded to in the introduction, water available for the ecological and anthropological demands are subjected substantially to basin characteristics, the climate, and land cover naturalness; together with what occurs in the basin as consequence, mostly by the human impact [4]. Taking this consideration, ecohydrology science introduces to its principles the five multi-dimensional parameters within river basins: water, biodiversity, ecosystem services for society, resilience to climatic changes, and cultural heritage and education (WBSR-CE) [4, 72].

From the displayed indicators examined in **Table 1**, there is no doubt that all of them can be part of an ecohydrological index. These indicators enter the concept of ecohydrology described above. However, the issue at hand is if the information to collect and measure the data is available; and if the indicators can be normalized in such a way that when correctly weighted, they are to be added to the composite index which will face calibration.
