ABSTRACT: Present work
introduces the sustainable useful storage capacity as the minimum storage capacity
able to satisfy the water demand for drinkable, industrial and irrigational
purposes and necessary in order to overcome water deficit situations which,
at least in Central Southern Italy, occur in the summer, when agricultural
demand is really high. Sediment volumes to be removed from the reservoir bottom
will be calculated as the difference between the current and the sustainable
useful storage capacities of the reservoir in study. The calculation methodology
of the useful sustainable storage capacity, based on the reservoir water
balance between inflows at the reservoir and water demand, has been applied
to the Camastra reservoir (Basilicata, Southern Italy), for which numerous
reliable data including more than 40 years of inflows and water supplied
volumes and data relative to 7 bathymetric surveys are available. Result analysis
shows that this methodology, at least in the study case, enables sediment
quantities to be removed more sustainably from a technical, economical and
environmental point of view.
