Possibilities to decrease of the phosphorus concentrations in wateshed and reservoir
Borovec, Jakub ; Hejzlar, Josef ; Maršálek, Blahoslav
P concentrations in the outflow from the watershed result from the group of factors including geology, climate, vegetation cover, morphology of streams and others. Selection of the watershed restoration strategy and its optimalisation depends on the regional, but the common idea for management of both watershed and reservoir should be the recovery to natural processes of nutrient retention together with the idea of sustainable development of the landscape. For the reservoirs, it is always lucrative to precede their overloading by phosphorus. Thinking about the decrease of P in the reservoir, the only possibility is to remove the sediments as the final deposition pool in the P-cycle. In case of the decrease of P in the water column, i.e. available for algae, another procedures of reservoir management can be used.
