The resulting changes to the wood surface geometry were expressed through the roughness parameters Ra and Rz. The beech wood examined was exposed to accelerated ageing for 600 hours. The experimental results showed that the degradation effects during accelerated ageing without water, in the so-called dry or water-free regimen, caused only a slight increase in roughness, while the regimen simulating rainy episodes resulted in a considerable roughness increase. These results imply that water has an important role in wood ageing process. In presence of water, the influence of radiation, oxidation and heat is more intensive and more pronouncedly reflected in the wood surface degradation and in changes to its morphology. In case of water-free regimen, the wood surface is subject to chemical changes due to UV radiation and heat-induced effects, but there need not be major changes to the wood morphology.
