Visual Water Engineering Calculators
Interactive calculators that update results, charts, and engineering visuals as you change the inputs. Use them for learning, planning-level checks, training, and technical communication.
Available
Manning Channel Visual Calculator
Explore channel geometry, depth, roughness, slope, flow area, velocity, hydraulic radius, normal depth, and rating curves.
Available
Culvert Hydraulics Visual Calculator
Explore pipe or box culvert size, slope, roughness, tailwater, full-flow capacity, HW/D, velocity, and overtopping warnings.
Available
Detention Routing Visual Calculator
Explore inflow hydrographs, outlet controls, basin storage, peak stage, peak outflow, drawdown, and flow reduction.
How Visual Calculators are different
A standard calculator gives one result after a user enters numbers. A Visual Calculator lets users change values with text boxes and sliders, then immediately see the drawing, chart, warnings, and calculation summary update. This makes the tools useful for education, early design discussions, client communication, and workforce training.
