This research work presents the results of the external analysis of the problem of the management of the lower Moche river basin in the valley of the same name. These results are framed in the construction of a multicriteria objetive function, to determine a partition of the basin in particular study zones calleded cluster. The objetive function involves the main hydrogeological parameters and some external parameters such as coefficients that involve socio-political criteria and some too specific such as evapotranspiration of different types of plants cultivated in the valley on the underground aquifer.

In this work, a basic epidemiological model is used to determine the evolution of COVID-19 in each of the regions of Peru. For determining the parameters of the model which characterize a certain epidemic, the reports of infected, deceased and recovered people provided by the Regional Health Management of Peru are used. As a result, we obtained the configuration of the infected, susceptible and removed which are consistent with the existing bibliography, thus we also obtain a time interval in which there is a considerable number of infected, the maximum number of infected and the date on which it occurs.
