For the purposes of calculation of the forces of the river flows will be considered forpositions in the dock docking feasible (very close to the river bank) speed of 3.0

knots (or 1.5 m / s). The velocity profile of the flow can be assumed constant, from

the top of the river water to the bottom of his riverbed.

Bolivar State .

To consider the effect of the wind on the operating conditions of the spring is used to

return a period of 5 years, so that the design speed is the maximum speed multiplied

by storm 0.78 (Reference: SEI / ASCE 7-02 "Minimum Design Loads for Buildings
