Floodplain inundation studies

Flood Studies

The floods produced by the sudden rise of the rivers in periods of intense rainfall are the most frequent danger and cause the majority of material and human damages.

Flood studies bring together different disciplines, including surface hydrology and fluvial dynamics typically addressed by geologists and biologists, channel hydraulics from civil engineering, geomatic techniques for three-dimensional characterization of the terrain and numerical methods for the iterative solution of the channel flow problem. In this sense, in order to carry out a flood study, the following tasks are carried out:

One of the main objectives of flood studies is to characterise the hydrological behaviour of the basin with the corresponding hydrographs for different return periods, as well as the hydraulic behaviour of the natural drainage network and the canalizations obtaining the flows, draughts, flow velocities and paying special attention to floodplains for the different return periods considered.

The cost ranges are highly variable depending on the characteristics of each study, where the number of rivers to be modelled and the extension of the study area can largely determine the final magnitude of the costs.
