Like other types of precipitation, snow can also descend to the earth with a change in its natural chemical structure by incorporating the contents of particles and gaseous substances in the atmosphere. It is possible that snow water will enter surface/groundwater resources and snow masses that exist on the soil for a long time may also affect the chemical structure of the soil.
Although surface/ground freshwater resources are generally used in the irrigation of landscaping plants in parks and gardens, the quality of snow water that can affect the vegetation in these areas is generally overlooked.
In this study, which was carried out to examine the quality of snow water in terms of physicochemical aspects, a total of 5 different stations from the outdoor green areas in Sivas Province were sampled in 2021 during the periods when the snowfall is the most intense.
Some physicochemical parameters of the samples obtained from melting snow (pH, conductivity, salinity, chloride, Ca, Mg, Total hardness, NO3-N, SO4, PO4, Li, B, Al, K, Na, V, Cr, Mn, Co, Ni, Cu, Zn, As, Se, Sr, Mo, Cd, Sb, Ba, Tl, and Pb) were measured at 15-days periods. In addition, using the Ca, Mg and Na values obtained, the Sodium Absorption Ratios (SAR) of the samples were also calculated.
While determining the quality classes of the obtained data in terms of surface water resources and irrigation water, the species of annual plants in the landscape of the sampled outdoor green areas were also determined and the possible effects of the physicochemical contents on these plants were also evaluated.
At the end of this study, it was determined that the snow water quality of Sivas province was compatible with the freshwater character, and some parameters that were found to be high in terms of surface water resources were not at values that would cause a negative effect in terms of plant irrigation water.
