The aim of the research was to find out which non-destructive methods can be used for determining the properties of wood placed in humid area and water. The research was carried out in order to propose suitable methods for detecting state of timber during regular inspection and maintenance of timber structures and elements in the watercourse. Wooden thresholds located in the watercourse belonging to the Divoká Orlice River Basin were selected for the measurement. The measured timber elements were already 9 years in the flow and the degree of damage to the built-in wood had to be assessed. The extent of biotic damage to water-soaked wood cannot only be determined by sensory methods. Resistance stop devices, a non-destructive ultrasonic device, a micro drill and an acoustic tomograph were selected for the evaluation. However, all commonly used modern diagnostic methods used for measurements in dry environment surveys cannot be used in the above terrain.
