Long-term Water Management Model in the Presence of Extraordinary Events

The stretched exponential model describing the sedimentation process of a reservoir was extended to appropriately encompass extraordinary events. These were divided into rapid and sudden events and programmatic events. Among the uncontrollable events, we analysed landslides or extreme weather events. Scheduled events included the construction of satellite dams upstream of the reserve. In addition, a continuous process that reaches a stationary condition is analysed. Finally, it was indicated how to become aware of non-routine events by having a limited number of bathymetric surveys available. The management plot in the presence of two sudden events, which take place at two different times in the life of the dam, was illustrated and discussed.
