Determination of hydrologic properties of forest floor according to different stand types

Forest floor plays an important role in the occurrence of a regular flow regime with rainfall basins significantly affect stream flow and delays the time to reach maximum currents. Recently studies about forest floor is stated that an important function of water storage and stop erosion. In additionally, forest floor has characteristics such as permeability increase, partly to prevent evaporation, upgrade ability water capacity and water quality. Therefore, forest floor properties performs the functions must be known. In this study, Sivas-Central Forest Management Office area, forest flor and soil properties were investigated changes according to different stand types (Poplar, Pine and Poplar+Pine). To determine different forest flor properties from stand types, were kept constant parent material, elevation and aspect factors. In research area, were taken 12 soil samples according to "Factorial Experiment Design" in order to determine of different stand types soils hydrophysical characteristics. And 81 forest floor sampling were taken from different stand types. Soil samples were evaluated sand, clay, silt, dispersion ratio values according to different stand types. Forest floor properties were evaluated saturation capacity, loss on ignition and bulk density values according to different stand types.
