Excavation Calculators

Precision calculators for excavation professionals and operations.

Pond Volume

Calculate excavation volume, water capacity, acre-feet, and swell factors for retention ponds using the frustum geometric formula required by civil engineers.

Trench Grade

Calculate total vertical fall for sewer and drainage pipe runs. Convert percentage grade into decimal feet for grading lasers.

V Ditch Flow Capacity

Calculate the maximum water flow rate (GPM & CFS) for V-ditches and swales using Manning's open channel flow equation.
