Soils, land cover, slope and rainfall, each with its source.
Here: woods on B soils, from the soil survey and land cover.
Next, draw what you plan to build: house lots.
In Results, pick the storm and compute.
The 10-year storm here is 5.18 inches.
The first compute uses a free site code. Press Compute again.
Now run every storm at once.
The site result: before and after, for six storms.
Next, add practices to bring the peaks down.
2 Today and proposed
1 min 38 s
Today's ground, what you plan to build, and the practices.
What it shows, in its captions
This site has its boundary and public data already.
Today: the land cover and soils, read from public data.
Proposed is what you plan to build.
Draw land use: first the house lots.
Pick what it is. Each choice shows its curve number.
Then the road. Ground you leave alone stays as it is.
Now Add green infrastructure: pick the kind, then draw it.
Say what drains to it. Here, half of the lots.
It is saved with starting settings you can change.
A second one on the north edge takes the rest.
Two practices, each with a share of what you drew.
Next: drainage areas read from the ground.
3 Drainage areas
1 min 2 s
Suggested from the ground for each practice, then kept or drawn.
What it shows, in its captions
Each practice needs the ground that drains to it.
Suggest drainage areas reads them from the ground in one press.
One per practice, clipped to the site. The rest bypasses.
A rough one is left unticked for you to check. Tick to keep it.
Each color is one practice's drainage area.
Use these to save them.
To adjust one, press Edit vertices and drag a corner.
Save the new shape. The acres update.
Or draw one yourself with Draw drainage area.
The legend shows what each practice treats, and the bypass.
4 Every storm
1 min 22 s
Six storms in one table and chart, and a fix to try.
What it shows, in its captions
In Results, pick a storm and compute once.
The first compute uses a free site code. Press Compute again.
Then Run all storms.
Six storms, from water quality to the 100-year.
Peak flow for existing, proposed, and with practices.
A storm passes when the peak with practices is at or below today's.
Water quality is judged on the volume the practices capture.
The chart shows flow over time for one storm. Pick another.
A storm fails? Suggest a fix.
It runs every storm with each practice at larger sizes.
Then it shows the smallest size that passes the most storms.
Nothing on the site changes until you change it.
Edit storms sets which storms run.
The water quality depth, a climate factor, and the storms.
Run again to see them.
Now each design storm is 10 percent deeper.

Assumptions, sources, and text for the report.
What it shows, in its captions
Explain says why each storm passes or fails.
The AI is off in this recording, so this is CurveNumber's own text.
Draft text writes a paragraph for the report.
You edit it, and it is reviewed before it is published.
Now the report itself.
The report opens in a new tab, ready to print.

The account, the site and the plan in these videos are made up. The ground,
the soils and the rainfall are read live from the public data. The AI features are off in
