IMPROVING WATER REGIME IN MLACA TĂTARILOR PEATLAND
Journal Title: Current Trends in Natural Sciences - Year 2017, Vol 6, Issue 11
Abstract
Following the project Restoration strategies of the deteriorated peatland ecosystems from Romania (PeatRo), it has been shown that Romania has 32 peatlands that need hydrological restoration taking into account the increasing of human activities and changes in land use. These peatlands are distributed in the Alpine region (30) and in the Continental region (2). In this paper, we started from the assumption that the evapotranspiration process can be reduced by decreasing the spread of colonizing species Betula pendula and Rhamnus frangula, in order to reduce the evapotranspiration rate. To establish the conditions for hydrology restoration, we used a conceptual model applied to the peatland functioning in order to quantify the water inflows (from runoff and rainfall) and outflows (overbank outflows, by evaporation, by colonizing species transpiration). To estimate the rate of evapotranspiration for these species, we used in the model as input data: height and diameter of the individuals, the number of individuals, the leaf area of individual, wind speed, temperature, humidity, the number of sun hours / day, the surface of the water table. Model results show that evapotranspiration process can be reduced after implementation of specific restoration activities, demonstrating a real improvement on water regime.
