Abstract
El embalse Bullileo fue diseñado como una obra de almacenamiento de aguas con fines de uso agrícola para la Región del Maule, Provincia de Linares. El embalse está construido sobre el río Bullileo, un tributario del río Longaví, el cual permite almacenar 60 Hm3, y así garantizar el riego de los usuarios del Río Longaví durante los meses de estiaje. El embalse Bullileo es administrado por la Junta de Vigilancia del Río Longaví. Aguas arriba del embalse se ubica la Laguna Amargo. Este trabajo se desarrolló en colaboración con la Junta de Vigilancia del río Longaví (JVRL) y tuvo como objetivo de analizar la factibilidad de usar la laguna Amargo para la operación del embalse Bullileo. Para ello se estudió la laguna y se aplicaron diferentes técnicas hidrológicas para determinar el caudal aportante y el volumen de la laguna. Mediante los sensores Hydrus 21 y Datalogger ZL6 de METER instalados en el año 2020, se logró analizar el comportamiento de llenado de la laguna. Sobre la base de este análisis se estudió la factibilidad de construir una compuerta de regulación que permita controlar el volumen de la laguna para ser usado como suplemento del volumen almacenado por el embalse, con el fin que la Junta de Vigilancia del Río Longaví (JVRL) pueda tener mejor manejo de los dos cuerpos de aguas, teniendo más opciones a la hora de tomar decisiones.
The Bullileo reservoir was designed as a water storage facility for agricultural use in the Maule Region, Linares Province. The reservoir is built on the Bullileo River, a tributary of the Longaví River, which can store 60 Hm3, thus ensuring irrigation for the Longaví River users during the dry months. The Bullileo Reservoir is managed by the Longaví River Surveillance Board. Upstream of the reservoir is the Amargo Lagoon. This work was developed in collaboration with the Longaví River Surveillance Board (JVRL) and aimed to analyze the feasibility of using the Amargo Lagoon for the operation of the Bullileo Reservoir. To do this, the lagoon was studied and different hydrological techniques were applied to determine the contributing flow and the volume of the lagoon. Using the Hydrus 21 sensors and METER ZL6 Datalogger installed in 2020, it was possible to analyze the filling behavior of the lagoon. Based on this analysis, the feasibility of building a regulating gate to control the volume of the lagoon was studied to be used as a supplement to the volume stored by the reservoir, so that the Longaví River Surveillance Board (JVRL) can better manage the two bodies of water, having more options when making decisions.
