Determinación de ecuaciones de intensidad y zonificación en la cuenca media alta del Río Paute

Abstract

An adequate hydrological study is essential for the development and subsequent construction of entire engineering project, be it vial constructions, water supply, agriculture and others.It is useful to know the relationship between the distribution, intensity and frequency of rainfall in order to provide control actions of maximum events in any project.The objective of this research is that analyzing the spatial and temporal variability of rainfall and its intensity, develop expressions for zoning intensities.This from the processing, validation, and subsequent analysis of instant information collected at different volume scales.Obtaining the expressions of frequencies, will allow us generate information in areas where there are no precipitation data and to describe more accurately the spatial temporal variability that this presents. The latest study by the INAMHI in 2015 allowed to divide Ecuador into 72 zones, each with its intensity equation, however, since each area covers too large an area, this research aims to create a more discreet division in the area located in the high middle basin of river Paute, allowing a more realistic study of rainfall in the sector. Was used the instant information of 18 rainfall stations, with an average duration of 13 years.These stations are monitored by: ETAPA EP, INAMHI and PROMAS University of Cuenca.Using statistical interpolation methods, it was concluded in the division of the high middle basin of river Paute in 14 areas, taking in each, the equation of intensity of the most representative station on the sector
