MACRA 2 2002

MACRA2 2002 is a software to perform hydraulic and static checks of gabion weirs and spillways. The software allows to check a wide number of flow conditions and different types of gabion weirs (vertical drops, stepped or sloped weirs).

The results provided are applicable to Maccaferri products. The calculations may not be realistic if other products are used .

For calculate this program, we need some input as below :

•  Geometry of Channel Section

•  River Bed Material (like Reno mattress, gabions, Enkamat, rip rap)

•  Hydraulic Data

 

Calculation of the hydraulic parameters

Macra2 2002 uses the following scheme to determine the hydraulic parameters .  

 

Weir with vertical drop

 

Stepped Weir

 

Sloped Weir
