# Aquifer Dvv Stress

`POST /api/v1/aquifer-dvv/stress`

## Request

- Base URL: `https://www.deepmapai.com`
- URL: `https://www.deepmapai.com/api/v1/aquifer-dvv/stress`
- Auth: none declared

Compute effective stress velocity change from water table change.

Uses the relationship between pore pressure, effective stress,
and seismic velocity (Hertz-Mindlin framework) to estimate the
expected dv/v change for a given water table fluctuation.
**Pricing:** Included in subscription tiers (legacy list price: GET /api/v1/billing/pricing).

Parameters (JSON body):
- base_velocity_mps : float -- Baseline shear wave velocity (m/s, required)
- water_table_change_m : float -- Water table change in meters (required, positive = rising)
- depth_m : float -- Depth of sensitivity (m, default 30)
- porosity : float -- Aquifer porosity (0-1, default 0.25)
- sensitivity : float -- dv/v per meter of water table change (default 0.002)

Returns predicted dv/v change, new velocity, pore pressure change,
and effective stress change.
