Abstract In the hydrographic system of the Rio Grande belonging to the basin of the Chone River, located in the province of Manabi, Multiple Purpose Dam Chone (PPMCH) is built with an investment of Ecuador of approximately 66 million US dollars. The dam will be finished in late 2015 and its purpose is to irrigate over 2000 ha of crops. The variations of species of inorganic concentrations of system hydrographic of the Rio Grande will be parameters to consider in chemical processes in function of precipitation, evaporation and evapotranspiration, therefore, this work contributed with a current characterization of the basin and a prediction of the environmental effects that cause the construction of the dam. The aim of this study was to calculate the precipitation, evaporation and evapotranspiration from three meteorological stations located in the system hydrographic of the Rio Grande, measuring ions Rio Grande waters in the dry season and rainy to determine the relationship between precipitation and evaporation depending on the concentration inorganic. The sampling was done across the Rio Grande basin in 2013 and 2014 for 111 stations.
