Análisis Hidrológico de la Cuenca Rocafuerte para Estimar el Potencial Hídrico de la Zona

Abstract

The Rocafuerte canton, founded in 1852, is a town in the province of Manabí in the central west territory. Its main economic activity is carried out in the fields of agriculture, livestock, and artisanal production of sweets, which are well received national and internationally. One of the main problems in the area that affects normality, is the water deficit during the low water periods, usually between the months of June to November. This work contains an assessment of the water resource that is generated in the basin where the Rocafuerte canton is located and that constitutes basic information for the control, optimization of works and projects aimed at the management and use of that resource. For the analysis, statistical and probabilistic methods were used in the management of the monthly rainfall records provided by the National Institute of Meteorology and Hydrology of Ecuador (INAMHI, acronyms in Spanish), among which the following stand out: data filling using the orthogonal correlation method, analysis of consistency and variability, estimation of multi-year average precipitation, application of the US Soil Conservation Service (SCS) method to calculate runoff and the multi-year monthly average distribution of precipitation. The meteorological stations in this study were 4, namely: Rocafuerte station (M165), Portoviejo (M005), Rio Chico (M454), and Junín (M462).
