This document provides a table of monthly water flow data from 1963 to 2021 for the El Tigre station. It then calculates several statistics on the annual water availability (supply) for the point of interest for the irrigation project, including the median (Q50%), third quartile (Q75%), and 90th percentile (Q90%). The water availability is calculated based on the long-term monthly flow data from the El Tigre station.

1. Pregunta 2 (1.5 puntos)
Calcule la oferta hídrica para el punto en interés del proyecto de irrigación.
Para el cálculo de esta pregunta cada grupo debe sustentar sus datos y estos debenser
actualizados (1950-2020).
SOLUCIÓN:
Oferta Hídrica  La oferta hídrica de una cuenca, corresponde también al volumen disponible
de agua para satisfacer la demanda generada por las actividades sociales y económicas del
hombre. Al cuantificar la escorrentía superficial a partir del balance hídrico de la cuenca, se
está estimando la oferta de agua superficial de la misma.
Q = V1*A1 + V2*A2 + V3*A3 + V4*A4 + V5*A5
Q = ∑Ai*Vi
