Present an argument in favor of bioengineering.

Bio-Engineering is the use of living vegetation, either alone or in conjunction with civil engineering structures and non-living plant material, to reduce shallow-seated instability and erosion.

Explanation:

DEVELOPMENT OF BIO-ENGINEERING:

In Germany and  Austria wishes to use the low-cost local materials and traditional constructions due to their Financial restrictions of pre-war years 1930's

ADVANTAGES OF BIO-ENGINEERING:

Re-establishing vegetation and store the hydrology from the surface to control of accelerated erosion.

Cost-effective treatments:

EXAMPLE:

GRASS PLANTING

Usually planting the large grass clumps in lines across the slope.

Horizontal lines are used to increase the protection against erosion.

ya the other dude is right

just finished the test, the answer is d, greg is the least cost-effective because he charges the most for the project
