| This paper analyzes the problems that may have flood control dams located on extremely dry areas, where water mainly flows in sudden floods. These dams can remain completely empty for a couple of years and being suddenly filled within hours. The 17 flood control dams located in the Segura River Basin (on the Spanish Mediterranean area) face these conditions. Some dams of this flood protection system, built more than 20 years ago, still have not received any flood and neither been subjected to a first impoundment. The design and operation of these dams has singularities, as these face specific risks arising from its purpose and from the characteristics of their location, as: rapid filling of the reservoir after long periods of inactivity, low quality of stored water, eutrophication, silting of the reservoir, clogging of the outlets, the settlement of population on the riverbeds downstream, low efficiency of the monitoring systems after long periods of inactivity and uncertainty about the dam behavior when it hasn't been loaded ever. The innovations and operation rules introduced (based on operation experience) for improving dam safety and resource use are described in this paper. | |
