Estudio para determinar la variación del coeficiente de escorrentía y su impacto en la capacidad de la red de alcantarillado en los colectores de las calles Arirumba e Imbabura

Abstract

This project collects information that was used in 1986 to calculate the runoff coefficient and flow collectors of Imbabura and Arirumba streets in the "Master Plan for Water and Sewerage Metropolitan Area Cuenca City"; the information includes calculation methods, results, plans and photographs.

In turn, past results are compared with actual results, proceeding the calculation the same way as was done in the “Master Plan” to evaluate properly the work capacity which is subject to the collectors. The calculation addresses two stages, one of them referred to the differences of the past, present and future in the use and occupation of land, governed by the "Urban Land Municipal Ordinances of the City of Cuenca", with this you get the runoff coefficients of each study area of the aforementioned two collectors.

The second stage is the analysis of the layout of the sewer and areas of contribution of each collector to calculate the current flow and its projection in 25 years. Because the system works as a combined sewage, the calculation is performed the sewage and the stormwater, the first proportional to the density of the population and its envelope, and the second subject to the procedure of the American Rational Method.

Finally there is a brief physical assessment of the final section of the collectors, through photographs that allow the sight of its state.
