SWATGenX: a working watershed model for your river, from national data

Every river starts with a question. Will there be enough water next summer? Where does the nitrate come from? What is happening in the ground beneath it?

Answering it takes a watershed model. Building one usually means months of collecting and preparing data before the science can begin.

SWATGenX changes where you start. Choose a stream gauge or a watershed anywhere in the lower forty-eight states, and we build a complete, ready-to-run SWAT+ model for it from national data, usually within a couple of hours.

Its streams, its subbasins, its land and its soils, in one model you can open on the map.

Calibrate it in the cloud against gauge records. Where our groundwater coverage reaches, order it with a groundwater model beneath it. Download it, run it, and make it your own.

Around it is a national map of the data water work depends on: millions of well records, thousands of stream gauges, water-quality measurements, and specialist data such as PFAS.

Work in your browser, from Python, or simply ask your AI assistant.

Every model we build stays in our care. When we improve it, we update yours and tell you what changed.
