HYDROLOGICAL STRUCTURING OF THE BASIN WHERE THE ROCAFUERTE CANTON IS SEATED, WITH ASSESSMENT VIEWS TO ITS WATER RESOURCES, ECUADOR

Abstract
The Rocafuerte canton, founded in the year 1852, is a town in the province of Manabí in the central west of its territory. Its main economic activity is carried out in the fields of agriculture, livestock and artisanal production of sweets, which are very well received at the National and international.One of the main problems in the area that affects the area's normal is the water deficit during the low water periods, which average terms present between the months of June to November of each year.The present 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 said 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), 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, which cover the study area, were 4, namely: Rocafuerte station (M165), Portoviejo (M005), Rio Chico (M454), Junín (M462)..
