Thus, the pressure wave moves actually at a finite velocity along the pipe,, in which K is bulk modulus of the liquid,mass density of the liquid, E elasticity modulus of the pipe wall materials, the correction coefficient is a function of E, the pressure increase of water hammer, and the dynamically elastic deformation of the pipe and expressed as[3] , and the radial and longitudinal strains of the pipe wall, as well asthe pressure increase.

The calculation of the annual average outflow of sediment. 4.3 Influencing simulation of debris flow The total handling material caused by the biggest rainfall of 250 mm in the debris flow gully area can be taken as risk prediction basis.
By analyzing the Fig. 13, we know that the solid material of debris flow solid material will not affect structures, but it will cause deposition of reservoir.
Influencing range shows: the solid material of debris flow solid material will not affect structures, but it will cause deposition of reservoir.

Materials Basic Composite Materials.
For the novel sensor modules, the piezoceramic material lead zirconate titanate (PZT) is used, which is processed to the corresponding components by project partner Institute of Materials Science at TU Dresden, using a polysulfone spinning process [7].
The process is characterised by a high degree of flexibility with respect to the materials to be processed.
