There is an integrated design of the raised curb location and elevation of street gutters, including its cross section layout, gullys set up, determination and optimization setting of the raised curb.

Based on the current status of Realtime Point-Picking software for range telemetry equipment,the main types of telemetry parameter to be processed are analyzed,a solution of Realtime Point-Picking common software is proposed,meeting the different task requirements by different parameter configurations.

The arrangement is suitable to the topography of baffle areathe deflecting nappe will extend vertically and longitudinally and diffuse sufficiently with its dissipation rate increasing in the air and outer edge of nappe falling in appropria.

Discussion on the horizontal length of jet flow and its factors of influence;

Velocity and hydrodynamic pressure distributions produced by high arch dam water jets in a water cushion pool;

The turbulent jet theory and water flow momentum equation are used to establish the mathematic model for calculating bedrock scoured balance depth of river bed under the action of left-right collision of water jet from high arch dam in considering 3-D diffusion,leakage collision flow and collision energy losses of water jet dispersion in the air.
