HydroComplete

HydroComplete brings professional stormwater engineering to Android with four real calculation engines — Sedimentology, Water Quality, Hydrology & Hydraulics, and Conveyance — in one treatment-train model builder.

Build your site as a network of watersheds, basins, channels, and BMPs, then watch your data flow through the full treatment train. Every number is backed by a real, published formula — rendered in full mathematical notation so you can check the math, cite the method, and defend the result.

FEATURES
• Visual treatment-train model builder — drag, connect, and analyze
• Sedimentology: particle-size-distribution routing, trap efficiency (Camp),
sediment basin performance
• Water Quality: pollutant removal through BMP treatment trains
• Hydrology & Hydraulics: SCS/NRCS methods, time of concentration, storm routing
• Conveyance: channels, pipes, and culvert hydraulics
• Live USDA SSURGO soil data and NOAA Atlas 14 rainfall from an interactive site map
• Full formula transparency with rendered mathematical notation
• PDF report export through the Android print system
• Offline manual included

Core calculations run on your device. An account is optional — sign in to sync your work and unlock Pro features. The app runs in landscape on both phones and tablets, so the full model builder and the whole toolbar stay on screen.

Built by a licensed professional engineer for engineers, designers, reviewers, and students who want to see the math.
