During 1940 (strong El Niño) and 1958 (weak El Niño), there were strong sedimentation processes mainly at the cross section located toward the head. Conversely, toward the mouth, the erosion processes were ahead. The study results were based in the depths behavior of 6 cross sections located along the estuary. The variations in the coast line were observed from the overlapping bathymetric charts for 1940, 1958, 1961, 1964 and 1979. Also, studies made for others authors was used to analyze the changes on the bathymetry and morphology at the Chone estuary. This study and previous ones demonstrated that, when there is El Niño: 1. The sea level rises and makes the waves break more into the shore line. As a result, there is erosion along the north coast of Ecuador where is our study area. 2. The strong rain increases the instability of cliffs located south the Bahía de Caráquez. 3. There is undermining at the slope of the mountains surrounding the estuary. This increases the sediments loads inside the Estuary. 1998 artículo científico 0303-7495 https://www.redalyc.org/articulo.oa?id=12627320 en http://www.redalyc.org/revista.oa?id=126 Bulletin de l'Institut français d'études andines application/pdf Instituto Francés de Estudios Andinos Bulletin de l'Institut français d'études andines (Perú) Num.3 Vol.27 |
