Spanish abstract | transversal de su cauce en el sitio de ubicación de la estación, una curva de calibración para analizar los valores de caudales máximos que dicha sección del río puede transportar, y dependiendo de esto se estimaron estadísticamente las implicaciones que tendría, o que ha tenido el rebase de sus agua, delimitando así (apoyado con la cartografía y considerando las áreas aledañas a la corriente) las respectivas zonas inundables. Finalmente, se diseñó el mapa que señala las zonas inundables del municipio de Quibdó y se elaboró un documento en el que se concluye que los barrios que tienen zonas con alturas entre los 25 y 27 m.s.n.m. o inferiores y que se encuentran a orillas del río Atrato y de sus afluentes constituyen zonas de amenaza alta y media, con periodos de retorno de 5 a 20 y de 50 a 100 años respectivamente |
English abstract | conclusions. Aerial photographs provided the most reliable images due to their scales, quantity and quality and the date of when they were taken. Radar images (INTERA) were also important when visually analysing a sectors topography as they were produced by an active microwave sensor (totally eliminating climatic obstacles). On the contrary, satellite images did not have great relevance due to the amount of clouds hampering any kind of analysis. Complementing these results, a calibration curve for analysing this sections maximum flow values was based on historical series data regarding the Atrato Rivers flows and maximum levels recorded at the Quibdo hydrographical station and the river-beds cross-section. Implications that the river would overflow or has overflowed were statistically estimated on these results, thereby setting the limits (supported by cartographic data) for the corresponding areas at risk of flooding. A map marking areas at risk of flooding in the urban zone of Quibdó was then designed and a document prepared concluding that neighbourhoods on land lying at 25-27 metres above sea-level (or less) and located near the banks of the Atrato river and its tributaries are considered as being mid- high-flood threat areas, having 5-20 and 50-100 year return periods, respectively |
