| Sumario: | Objectives: To determine the superficial water balance from Mantaro Valley because of evapotranspiration system changes, precipitation and runoff during the periods from 2010 to 2013. Methods: We used the indices evaluation method, which allows to analyze the seasonal water deficit, deducted from the Thornthwaite approach. We calculated the water index, analyzing the humidity and aridity indices from the monthly mean temperature values. The warm annual index has been calculated taking into account the “a” value, known as aridity index which constant value is obtained for Mantaro Valley. Results: The annual superficial water index value was determined in Im = 55,72, the humidity index in Ih = 42,7, the aridity index in Ia = -21,71 and the annual runoff in Qa = 412 mm. Conclusions: In function of the aridity index, the Mantaro Valley superficial hydric balance shows a water seasonal deficit for the months of june, july, august and september which corresponds to winter; and in function of the humidity index shows an excess for the months of december, january, february and march which corresponds to summer; these values are compared with the water deficit coefficient for may and lasts until september, covering from the late fall season to the end of winter. |
