Pricing Excavation and Backfill

Backfill, in construction, is the activity of returning the soil and gravel that are removed during building construction or using them again to toughen and support the foundation of the building or any other structural component.

Question

There is a basin of 150 km2 of surface. The main
channel is 10 km long and itsslope is 0.5%.
Determine the expense for a T=5 years
Considerations:
• The basin is originally made up of grasslands
with a slope greater than 1% and with soils
corresponding to fine sand and silt.
• The rain is uniform and covers the entire basin
• The i-d-T curves are available, which is given
by: i= (220T^0.55)/(d^0.68) mm/h, T in years and
d in minutes.
