Conclusions
-
1.
The proposed method of calculating the minimum required discharges in free and regulated streams should be considered as an alternative for solving the problem of partial diversion of the surface runoff of rivers in projects for territorial redistribution of the water resources of the nation. This method makes it possible, by means accessible to the designer, to take into account in a first approximation in the discharge side of the water-management balances, the volumes needed to ensure water quality and the conservation of the river as a basic element of the landscape.
-
2.
The hydrograph of the nature-protecting discharges should be considered as an exceptional phenomenon in the runoff regime of the stream, which should not occur during several years in succession.
-
3.
The different concepts in the analysis of the minimum required discharges call for further elaboration and substantiation.
