Hydrological Balance for Filling the Pits, Transformation Daily Rainfall to Daily Flow Rate for the Basins that Drain to the Pits. Model GR4J

This article presents a conceptual model for the supply of runoff information storage areas. The concepts of daily hydrologic balance equation and the simplification runoff transformation processes in the subsoil have been taken as reference, using tank models that take into account the temporary storage of runoff. This proposed conceptual model, used especially in open pit mining, allows any scenario to determine the evolution of the filling. In the case of a mining operation, the filling of the exploited areas seeks to restore the natural state of the area to mitigate the effects on the biosphere. The filling process requires the evaluation of the daily hydrological balance in the basins that are taxed to the storage area and the evaluation of the particular hydrological variables. Since the objective function of the model is the duration of time changes in the daily calendar of storage areas, it is necessary to define the model of rain in the future. In the model integrated in the Hec-Hms software of successive tanks.
