Este libro desarrolla modelos matemáticos para estimar los requerimientos hídricos de cultivos estratégicos (papa, arveja, maíz y cebada) en la región central de Boyacá, zona afectada por la variabilidad climatica heladas, sequias, lluvias extremas que compromete la productividad agricola. Basados en el calculo de la evapotranspiracion diaria de referencia (ETO), se aplicaron dos metodologias para hallar la evapotranspiracion de cada cultivo:1) Modelo de coeficiente unico: ETc = Kc ET02) Modelo con el coeficiente dual, suma de los coeficientes de transpiracion y evaporacion: ETc = (Kc + Ke ) ET0donde se integran variables climaticas (radiacion solar, temperatura, humedad, velocidad del viento) y caracteristicas de los cultivos. La investigacion incluye un sistema computacional en MATLAB para automatizar los calculos, simular escenarios hidricos y validar resultados con datos de las estaciones ECFAT-UPTC e IDEAM. Ademas, se incorporan ajustes por estres hidrico y dinamica del agua en el suelo.Esta obra, resultado del proyecto SGI 3334 (UPTC), combina rigor teorico con aplicaciones practicas ofreciendo herramientas para optimizar el riego, reducir riesgos climaticos y fortalecer la seguridad alimentaria de la region.
