Water balance modeling - Mine Closure

Water balance modelling is usually divided into operational units which are modelled separately. When these units are combined, water balance model for the whole mine site can be generated. If different major units affecting water balance are missing, the model is useless. Therefore, water balance model has to always cover the whole mine site.

Water Balance: Meaning, Components and Types | Hydrology | Geology

The water balance is an accounting of the inputs and outputs of water. The water balance of a place, whether it is an agricultural field, watershed, or continent, can be determined by calculating the input, output, and storage changes of water at the Earth's surface. The major input of water is from precipitation and output is evapotranspiration.
