Hydrology and Watershed Management Studies

The Guájaro Reservoir in northern Colombia is a hydrosystem that is supplied by an artificial channel (Canal del Dique) through a system of floodgates. During the last decades, has been presenting problems of excessive use, which is why, it is necessary to regulate the hydraulic structures that serve this water body, as they play an important role in managing the levels that in turn affect the water supply. The present work is carried out as a sustainability management alternative of the reservoir. A two-dimensional hydrodynamic model (EFDC Explorer) and its calibration is implemented using time series of the free surface levels, and comparing the measured velocities and those estimated by the model for two different climatic periods, to assist the operation of the Hydrosystem Canal del Dique-Guájaro Reservoir sustainability. The corresponding comparisons showed a good behavior between measured and simulated data, based on the quantitative results of Nash-Sutcliffe reliability method. It is considered that the results are quite satisfactory and allows the estimation of conditions for restoration, its use, as well as the incoming and outgoing water through hydrosystem channel-reservoir.
