Comparative Analysis of Typical and Sustainable Drainage System to Floods Control in the Andean Mountain Range

EasyChair Preprint 10981

Abstract

Every construction project should have a drainage 
system so that it works correctly with a projection to future 
decades. The main function of sustainable drainage systems is to 
reduce the flow resulting from heavy rains, in addition to 
minimizing costs and having a wide and free landscape. To find 
the solution to this problem, it is proposed to make a comparison 
between a sustainable drainage system and a typical system, 
having as a structure the management of water produced by 
rainfall in order to mitigate flooding. Likewise, information
acquired from the SENAMHIInstitutional page was used, such as 
rainfall and temperatures, with which evapotranspiration and
runoffwere determined, whichwastaken asthe most critical, to find
the most critical flowof 0.002m3/s. These values were found with
their respective formulas. Finally, once the most critical flow was 
obtained, it was proposed in the hydraulic modeling with a green 
ditch and a traditional ditch in the HEC-RAS software, with 
positive results for both designs. However, the design with a green 
ditch showed a slightly greater difference, evidencing that this
proposal is more viable. In addition, its implementation is
economical and eco-friendly for theenvironment.
