Atlantic Biocarbons · Stormwater Intelligence

Quantifying the stormwater
value of biochar-amended soils.

A rigorous, field-validated hydrologic model built on Green-Ampt infiltration theory. Compare runoff reduction, curve number, and water retention across native and biochar-amended profiles — with or without soil fracturing.

METHODOLOGY

Peer-reviewed hydrology, now in your browser.

Every calculation — from Kozeny-Carman saturated hydraulic conductivity through a 109-bin pore-size distribution to a 100-step layered Green-Ampt infiltration simulation — is faithful to the reference spreadsheet. Select a biochar product from our catalog and configure your site; the proprietary material specs stay in the lab, not in your browser.

The calculator

Configure your site

Results recompute instantly as you edit. Field values shown below reflect a representative sandy loam amended with 4.4% biochar — reset to defaults any time.

Step 01

Site, treatment & rainfall

Geometry of the treatment area, upstream impervious run-on, and design storm.

Step 02

Hydraulic measurements

If Ksat or water retention was measured in the field, switch these on to override the derived values.

Step 03

Soil & biochar

Native soil properties plus the biochar product and application rate. Biochar specifications are standardized per product and applied automatically.

Particle-size distribution, skeletal/envelope densities, intra-pore volumes, and shape factors are set per Atlantic Biocarbons product and applied automatically on the server. Full specs are proprietary and are not included in the calculator bundle.
