Hydrology and hydraulics

The analyses of hydrological and hydraulic aspects will cover the water collection and conveyance system (leat system) in the upstream watershed as well as the storage and water distribution network within the mining area.  The maximum water yield from the catchments drained by the leat system will be estimated based on hydrological methods and compared to the hydraulic capacity of the channels.  Based on the available water yield and the storage volume of the reservoirs existing in the mining area it will also be attempted to identify the likely operation mode of the system, in particular the frequency of reservoir flushing and refilling. This will give an indication of the possible mining intensity in different seasons of the year.

In a final step the hydraulic characteristics of reservoir flushing will be analysed in detail using a 2-dimensional numerical model. The objective of the simulations is to improve the understanding of the flushing procedure with respect to the flow intensity and the possible mobilization, transport and deposition of soil material in the downstream area.
