x402
Theis Confined Aquifer Multi-Well Pumping & Recovery Superposition is a paid API for AI agents from detect.halowerk.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-11-04).
Computes explicit drawdown and recovery at arbitrary observation points in a confined aquifer by superposing Theis solutions across multiple pumping wells with piecewise-constant pumping rate histories.

How this service works
Compute explicit pumping and recovery drawdown superposition in an ideal aquifer.
Output
Returns superposed drawdown values (in meters or consistent units) at each queried observation position and time, computed by applying the Theis well function to each pumping step of each well and summing contributions via the principle of superposition, including both pumping-induced drawdown and recovery phases.
Example use cases
Well interference assessment for new wellfield
“I have a confined aquifer with transmissivity 300 m²/day and storativity 0.0002. I want to place three wells at (0,0), (150,0), and (75,130), each starting to pump at 800 m³/day from t=0. What's the total drawdown at the centroid point (75,43) at t=10000 days?”
Pumping test recovery analysis
“We ran a pumping test in a confined aquifer — transmissivity 450 m²/day, storativity 0.00005. One well at (0,0) pumped 1200 m³/day from t=0 to t=86400, then stopped (rate change of -1200 at t=86400). Can you compute the residual drawdown at an observation point (50,0) at t=172800 days to analyze the recovery?”
Multi-step pumping schedule drawdown forecast
“For a confined aquifer with transmissivity 1000 m²/day and storativity 0.001, I have a single well at (0,0) with a stepped pumping schedule: 500 m³/day starting at t=0, increasing by 300 m³/day at t=2000, then decreasing by 200 m³/day at t=8000. What is the drawdown at (100,0) at t=15000 days?”

Endpoint
POSThttps://detect.halowerk.com/v1/F-TD2000-GEO-INDUSTRY-B008/theis-confined-aquifer-multiwell-pumping-recovery-superposition?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need analytically exact drawdown or recovery calculations in a homogeneous, isotropic confined aquifer under the Theis assumptions, especially for multi-well interference or stepped pumping histories. Prefer this over numerical groundwater models when the aquifer is confined, laterally infinite, and you need fast, deterministic answers without discretizing a grid. Best suited for pumping test analysis, wellfield design screening, and regulatory drawdown estimation.
Side effects
- Transmissivity or storativity out of allowed range returns validation error
- Well or query positions outside ±10000 coordinate bounds rejected
- More than 16 wells or 32 pumping steps per well exceeds schema limits
- More than 32 query points per request returns error
- Zero or negative transmissivity causes numerical instability
- Query time of zero with active pumping may produce undefined Theis function value
- Malformed artifact/claim structure causes request rejection
