Load stage at an upstream gauge (Gauge 1) and a downstream gauge (Gauge 2), check and confirm the values, then compute stage at the SWOT nodes between them with the calibrated BRACE model. Values read from screenshots are measurements of a picture: check them against the image before confirming.
1. Choose the reach
Downstream gauge (Gauge 2)
Choose the upstream gauge
2. Enter stage for each gauge: screenshot from this device, or type the values
Gauge order check
Load both gauges to check that Gauge 1 is upstream of Gauge 2.
3. Stage ensemble at the nodes between the gauges
Uses BRACE parameters loaded from external files per segment. No parameters are built into the app, and nothing is interpolated between gauges.
