This paper proposes a new methodological approach to silted reservoir management and defence,which combines the reservoir rehabilitation process and the utilization of the recovered water volumes and *** approach,strategic from both the economical and environmental points of view,is here defined as Economic Environmental Defence(EED) of a *** EED approach is applied to the case study of Guardialfiera reservoir,where the available experimental data allowed the estimation of siltation up to date,the analysis of the distribution of sediment particle size along the reservoir bottom and the possibility to propose a feasible utilization of water and sediments resulting from the reservoir rehabilitation.

EFFECTS OF RIVER NETWORK WORKS AND SOIL CONSERVATION MEASURES ON RESERVOIR SILTATION

引用

International Journal of Sediment Research 2007年第4期22卷 273-281页

作者： bruno molino Rosa VIPARELLI Annamaria DE VINCENZO Prof. Department of Environmental Physics and Engineering University of Basilicata 85100 Potenza Italy

Knowledge of the morphological dynamics of a water course is essential for management of reservoir siltation. With an example of sedimentation in a reservoir in Basilicata, Italy, this paper demonstrates the effect on reservoir siltation of the hydraulic works, which are aimed to reduce sediment transport along the fluvial network and to prevent part of the sediment discharge from reaching the lake. The effect depends on the river type and on the the geological features of river basin slopes. The paper also shows how mass erosion can significantly contribute to development of reservoir siltation. Finally, preliminary results are provided about the time needed for river training works to be effective.

The rehabilitation of a reservoir: A new methodological approach for calculating the sustainable useful storage capacity

引用

Agricultural Sciences 2013年第8期4卷 46-50页

作者： Annamaria De Vincenzo bruno molino Department of Agricultural Environmental and Food Sciences University of Molise Campobasso Italy School of Engineering University of Basilicata Potenza Italy

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.
