Diseño hidráulico del canal natural Colibrí, ubicado en Chongón, provincia de Guayas.

Abstract

The increase in the magnitude of extreme hydrological events, the waterproofing of the basin and the urban growth may cause that natural channels not to have the capacity to withstand the new conditions ahead, which make design and planning necessary to increase the hydraulic capacity of natural channels with reconformation and lining of natural channels, such as the Colibri channel. Currently, the Colibrí channel is located the urban area of Chongón with a length of approximately 1200 meters that due to urban growth and invasions of civil structures have cause the channel to be filled with natural landscape, this have caused the channel hydraulic capacity decrease and a solution is necessary since the channel currently have flood problems that affect directly to residents. After a study using the HEC-RAS and HEC-HMS software where the issues of the main channel were identified, for a long-term solution that allows the channel new design to bear extreme hydrological events by doing a reconformation and lining of the channel that are the most viable and convenient options.
