Dinámica y sedimentología de los depósitos de la avenida del río Júcar en octubre de 1982 en su tramo bajo

Se estudian los sedimentos depositados durante la avenida de 19, 20 y 21 de octubre de 1982 del río Júcar. Tanto por su morfología como por sus características sedimentológicas se han separado dos tramos del cauce: en el alto, confinado, se depositaron arenas antes de la rotura de la presa de Tous y gravas después de la misma. En el tramo bajo, no confinado y  sobreelevado, se depositaron limos y arenas finas

Spain

This chapter presents a review of the situation concerning the various geomorphological hazards in the country, including some information about existing programmes for research, control and mitigation. With its great variety of climatic, geological and morphodynamic environments, Spain is subject to every kind of natural hazard: tsunamis, floods, volcanism, and mass movements. The whole of the territory is prone to some kind of geomorphological hazard but it is in the eastern and southern coastal strips that the risks are greatest. One of the main problems for the mitigation of geomorphological hazards in Spain is the lack of an appropriate regulatory framework for the incorporation of natural hazard assessments into land-use planning and management at the macro-, meso- and micro-planning levels. The coverage of hazard mapping is still far from complete or adequate, and much work remains to be done. There has been considerable diversity in the methods used for risk assessment and for the cartographic representation of natural hazards. An urgent need is to establish common, accepted methodologies and criteria, based on indicators defined as clearly as possible, and to standardize map legends and scales for different planning levels. Information programmes for the general public also need to be considerably expanded

Floods in the Amarguillo river basin (Toledo)

Flood ocurrence in the Consuegra (Toledo) region has been studied according to historical records and hydrometereplogical methods based on rainfall data. The Amarguillo river, upstream from Consuegra, has a flow around 109 m3/seg. for 100 years, which represents almost half of the total flow (235 m3/seg. for 100 years). Main floods occur in the upper basin, where Consuegra Is located, related to larger slopes but less Infiltration capacity. Adjusting these results to the catastrophic flood that ocurred in 1891, it has been estimed to have a recurrence period of 100 years. The disastrous effect o f this flood can therefore be justified by the channel constriction by buildings, rather than to other external causes like an ancient roman dam break, upstream from Consuegr
