AquaFluxVortex — Surface Drainage Inlet Calculator

THE PROBLEM

Urban waterlogging during monsoon season overwhelms conventional drainage systems, causing severe flooding and disruption. The AquaFluxVortex device uses vortex mechanics to dramatically improve drainage efficiency.

Urban waterlogging during monsoon — flooded streets

Conventional drains fail under heavy rainfall

INPUT PARAMETERS

Provide the road geometry and climatic data. The algorithm applies the Rational Method for runoff estimation and an experimentally-derived enhancement factor to determine the optimal device configuration.

Rainfall Intensity mm/hr required

Distance Between Drains metres required

Width of Road metres required

Road Gradient required

Turbidity Level required

Typical Flood Height metres required
