“…Also, numerous river flow assessment methods have been proposed in several countries over the past decades [4,5]. These methods have been classified as hydrological [6], hydraulic rating [7], habitat simulation [8], holistic [9], combination, and other methodologies [10]. The methods make different assumptions and differ in the data and methodology used to compute ecological flow requirement [11].…”

Many dams have been constructed or are planned all around China. These dams significantly change the hydrological regime and sand concentration downstream, and subsequently affect the river habitat and riverbed substances. Therefore, a good understanding of the river habitat is urgently required to undertake efficient measures for fish diversity conservation. A multi-objective assessment method based on the Physical Habitat Simulation system (PHABSIM) was utilized to calculate the ecological river flow demand using maximum weighted usable area (WUA) and minimum river discharge as the main objectives. The study employed this method to assess ecological water flow demand in the National Nature Reserve for Rare and Endemic Fish in the Upper Reaches of the Yangtze River in China. Multiple factors such as the degree of endangerment, fish value (ecological value, economic value and scientific research value), data acquisition difficulty, and species representativeness were taken into consideration during selection of indicator fish for coupled habitat analysis. Requirements for both growth and breeding during the study period were considered. Ten species of fishes were chosen as indicator fishes, including floating egg and sinking egg fishes. Additionally, we applied the principle of "minimization of habitat demand and maximization of ecological demand" to include the needs of all indicator fishes. Further, this method comprehensively considered requirements for ecological flow and economic development. The results highlighted that an optimal ecological river flow demand of 2395 m 3 /s was needed to satisfy the needs for habitat protection and 1890 m 3 /s was required to meet the needs of social and economic development. The methods used in this study and results obtained, provide a valuable reference for water resources planning and ecosystem protection in other rivers and lakes.

“…In particular, this category includes two types of methods: -simple experimental methods: in which the MVF is correlated to the wet boundary or to the section width needed for the development of the species considered, assuming a simple criterion for assessing the suitability of the environmental parameters; -complex experimental methods: in which certain continuous curves are used to assess the suitability of the environmental parameters; for instance, the microhabitats method provides a curve correlating the area considered available (a function of the flow, the mean velocity and the type of substratum) to the flow of the watercourse; the maximum on this curve corresponds to the optimal MVF value, as already mentioned above. It should be noted that the Microhabitat method PHABSIM is frequently used for fluvial environments, while the Habitat Quality Index and Pool Quality Index are often used in torrential environments [9][10][11][12][13].…”

This paper analyses the problems related to drinking water catchment in a torrential river habitat. In this context, estimating the minimum vital flow (MVF) needed to ensure optimal conditions for the survival of local wildlife species is no simple task as the evaluation of both the MVF and the water balance in the catchment basin is dependent upon hydrological parameters whose extremely variable values often make anthropic intervention incompatible with optimal natural flow conditions. In the case examined here, river discharge measurements taken during a survey campaign to assess the state of the river during a period of low water flow are compared with the MVF value. This comparison reveals measured discharge values that are incompatibly low compared to those calculated by means of the usual methodologies adopted for estimating the MVF. On the other hand, however, the sustainability of the quantity of water collected from the basin is confirmed by the mean yield of the reference Hydrogeological Unit, by the relative potential of the aquifer and, therefore, by the potential of the spring itself. A solution is proposed which, although specific to this context, does constitute a more general methodological approach.
