| Summary, etc |
La presente investigación se realizó en la Unidad de Riego Catarina, ubicada al sur del departamento de San Marcos, con el objetivo de diagnosticar la eficiencia del sistema de riego, determinar las eficiencias de conducción y aplicación, y evaluar el nivel tecnológico de los usuarios. La metodología incluyó mediciones de eficiencia de conducción y aplicación, muestreo estratificado aleatorio de 19 parcelas, determinación de la velocidad de infiltración, análisis de calidad del agua, contenido de sólidos en suspensión y aplicación de encuestas. Los resultados evidenciaron una eficiencia global del sistema de 34 %, eficiencia de conducción de 81 %, eficiencia de aplicación de 42 %, pérdidas significativas por percolación y escurrimiento superficial, además de agua apta para riego y deficiencias en los conocimientos técnicos de los usuarios. |
