2. 1. INTRODUCCION
La cuenca del río Coata está ubicado en el departamento de Puno, al sur de
Perú; éste podría verse afectado, ante un potencial cambio futuro principalmente
en las condiciones medias del clima, por lo que es de sumo interés inferir qué
cambios se presentarían en el caudal del río Coata, fuente indispensable
dedicada en mayor medida al sector agropecuario.

3. 2. OBJETIVOS
2.1 Objetivo General
 Identificar y calcular la oferta hídrica para una captación en un
determinado punto.
2.2 Objetivos específicos
 Calcular la precipitación media en las cuencas por el método Kriging.
 Calibrar y validar el modelo hidrológico GR2M.
 Generar caudales medios mensuales en la captación designada.
