Parametrização de um modelo de balanço hídrico de cisternas rurais.

Abstract

Rainwater catchment systems using cisterns are very numerous in the Brazilian northeastern region. The efficiency of those systems is related to the maintenance and management of their components, so that, if well managed and preserved will guarantee water supply in adequate quantity and quality throughout the year. Water balance equations can simulate their behavior using historical time series of rainfall and, thus, evaluate whether the system is appropriate for each family usage. For a precise simulation it is necessary to parameterize those equations. In this paper, the parameterization process is presented for systems in the semiarid region of the State of Paraiba. The results show that the simulation represents satisfactorily the observed behavior of the systems. The errors are evaluated and characterized.
