| Zusammenfassung |
| Flash floods are of major relevance in natural disaster management in the
Mediterranean region. In many cases, the damaging effects of flash floods
can be mitigated by adequate management of flood control reservoirs. This
requires the development of suitable models for optimal operation of
reservoirs. A probabilistic methodology for calibrating the parameters of a
reservoir flood control model (RFCM) that takes into account the stochastic
variability of flood events is presented. This study addresses the crucial
problem of operating reservoirs during flood events, considering downstream
river damages and dam failure risk as conflicting operation criteria. These
two criteria are aggregated into a single objective of total expected
damages from both the maximum released flows and stored volumes (overall
risk index). For each selected parameter set the RFCM is run under a wide
range of hydrologic loads (determined through Monte Carlo simulation). The
optimal parameter set is obtained through the overall risk index (balanced
solution) and then compared with other solutions of the Pareto front. The
proposed methodology is implemented at three different reservoirs in the
southeast of Spain. The results obtained show that the balanced solution
offers a good compromise between the two main objectives of reservoir flood
control management. |
