Overview
The Guájaro Reservoir in northern Colombia is a hydrosystem supplied by the artificial Canal del Dique through a system of floodgates. Over recent decades it has experienced problems of excessive use, making it necessary to regulate the hydraulic structures serving the water body, since they play an important role in managing the levels that in turn affect water supply.
Model Setup
The work was carried out as a sustainability management alternative for the reservoir. A two-dimensional hydrodynamic model was implemented in EFDC Explorer and calibrated using time series of free surface levels, comparing measured and model-estimated velocities for two different climatic periods, to assist the operation of the Canal del Dique–Guájaro Reservoir hydrosystem.
Key Findings
The comparisons showed good behavior between measured and simulated data, based on the quantitative results of the Nash-Sutcliffe reliability method. The results are considered quite satisfactory and allow the estimation of conditions for restoration and use, as well as the incoming and outgoing water through the hydrosystem channel-reservoir.
