The topography of the area of influence was obtained based on the topographic charts in a scale of 1:1000 provided by the Planning Department of the GAD Municipality of Ambato, then the mathematical simulation model of the avenue was continued with the Hec-Ras program, which generated the flood area of the analyzed area, thematic plans were drawn up and the summary of plans was drawn up in which the recommended distance of construction of civil works from the river axis was indicated. The hydraulic design of the project was based on the NEVI-12-MTOP standard; Volume No. 2 - Book B, the Ecuadorian Construction Code, part IX, Sanitary Works CO 10.07 - 601 and the Hydrology, Hydraulics and Drainage Manual of the Ministry of Transport and Communications of Peru, has determined a return period of 261 years, a design flow of 123.18 m3/Sg, a maximum flood height of 5 meters above the level of the river bed and a flood area of 44.48 hectares. |
