Estimation of the Water Balance of a Small Tropical Andean Catchment
The present study seeks to estimate the water balance that results as a product of the variation of precipitation and temperature over the Chaquilcay microcatchment, a natural system that intercepts with the surface of the Aguarongo Protected Forest in Gualaceo, Ecuador. Four meteorological stations of the National Institute of Meteorology and Hydrology (INAMHI) were studied, which are divided into climatological and pluviometric, with time series of over 30 years, (1982-2015 period). In order to quantify the contributions and losses of water, statistical analyzes of the time series and surveys of in situ information were carried out. The methods used are linear regression, streak test and double mass curve. To fill and validate the series of precipitation and temperature, reference temperatures of the isothermal raster of Ecuador were included in the pluviometric stations. Additionally, a digital elevation model (MDE) was used to predict the amount of sunshine, and the Thornthwaite evapotranspiration method (1948) was applied from the obtained data. The results show acceptance of the meteorological records, while in the soil analysis we obtained the following data: Humidity, 62.38%; organic matter, 21.29%; field capacity, 18.71 mm and a flow of 1.89 m³ / s during the month of May. Finally, the water balance indicates 843.7 mm of annual precipitation, a storage difference of 18.71 mm representing 2.22% of total precipitation, an surplus of 144.5 mm, and actual evapotranspiration of 680.5 mm, with 17.13% and 80.65%, respectively.

El presente estudio estima el balance hídrico, debido a la variación de precipitación y temperatura sobre la microcuenca Chaquilcay, sistema natural que intercepta con la superficie del Bosque Protector Aguarongo, Gualaceo-Ecuador. Se estudiaron cuatro estaciones meteorológicas del Instituto Nacional de Meteorología e Hidrología (INAMHI), las mismas se dividen en climatológicas y pluviométricas, con series temporales mayores a 30 años, periodo (1982-2015). Para cuantificar los aportes y pérdidas de agua, se realizaron análisis estadísticos de las series temporales y levantamientos de información in situ. Los métodos utilizados son regresión lineal, test de rachas y curva de doble masa para rellenar y validar las series de precipitación y temperatura, en las estaciones pluviométricas se incluyó temperaturas referenciales del ráster de isotermas del Ecuador, también se empleó un modelo digital de elevación (MDE) para predecir heliofanía, a partir de los datos obtenidos se aplicó el método de evapotranspiración de Thornthwaite (1948). Los resultados muestran aceptación de los registros meteorológicos, mientras en los análisis de suelo se obtuvo humedad 62.38%, materia orgánica 21.29% y capacidad de campo 18.71 mm y caudal de 1.89 m³/s durante el mes de mayo. Finalmente, el balance hídrico indica 843.7 mm de precipitación anual, una diferencia de almacenamiento de 18.71 mm representando 2.22% de precipitación total, un excedente de 144.5 mm y evapotranspiración real de 680.5 mm, con 17.13% y 80.65% respectivamente. Este equilíbrio de água estudo estima, devido à variação de temperatura e precipitação no micro Chaquilcay, sistema natural que se cruza com a superfície de protecção Floresta Aguarongo, Gualaceo-Equador. quatro estações meteorológicas do Instituto Nacional de Meteorologia e Hidrologia (INAMHI), eles são divididos em tempo e precipitação, com séries mais tempo período de 30 anos (1982-2015) foram estudados. Para quantificar as contribuições e perdas de água, foram realizadas análises estatísticas das séries cronológicas e levantamentos de informação no local. Os métodos utilizados são ensaios de regressão linear e curva dupla massa para encher e validar a série de precipitações e a temperatura no estações de precipitação temperaturas referenciais quadriculação isotérmicas Equador incluído um modelo de elevação digital também foi usada ( MDE) para predizer heliopania, o método de evapotranspiração de Thornthwaite (1948) foi aplicado a partir dos dados obtidos. Os resultados demonstram a aceitação de registos meteorológicos, enquanto em análises de solo foi obtido 62,38% de humidade, 21,29% de matéria orgânica e de 18,71 milímetros e a capacidade do campo de fluxo de 1,89 metros cúbicos / s, durante o mês de Maio. Por fim, o equilíbrio de água 843,7 milímetros indica precipitação anual, uma diferença de armazenamento 18,71 milímetros que representa 22,2% do total de precipitação, um excesso de 144,5 milímetros e 680,5 milímetros de AET, com 17,13% e 80,65% respectivamente.
