Abstract

Water is a fundamental natural resource for living beings. The economic development of a population depends on the availability of water. Rain is one of the most important natural sources for the development of the agricultural and livestock sector, and sanitation only needs good management. However, climate change is leaving serious environmental, economic and social consequences and even human losses. The city of Acobamba is characterized by agricultural production, where harvests are carried out once a year taking advantage of the annual rainfall. To carry out this work, monthly and annual rainfall data from a meteorological station were used. The historical data analyzed range from 1994 to 2014 (21 years). The data were downloaded from the SENAMHI-Peru website. Data analyzes were processed in Microsoft Excel (2016) using basic descriptive statistics formulas. In the 21-year series, the year 2011 was the wettest with 1088.80 mm of precipitation, the year 1994 was the driest year with 327.22 mm of precipitation. The maximum monthly precipitation was recorded in February 2011 (256.30 mm). The month of February was identified as the rainiest month and the month of June as the driest month. The months with the highest frequency of rain were December, January, February and March, which in volume represent more than 65% of the total precipitation. The annual average records a precipitation of 697.38 mm.
