Abstract

Groundwater forecasts that support sustainable aquifer management often account for climate and hydrologic uncertainty, but they typically assume that human pumping behavior remains stable over time. In intensively irrigated aquifers, this assumption may not hold because pumping decisions can shift with drought, crop choice, energy costs, irrigation technology, regulation, and conservation programs. We examine how non-stationary pumping behavior affects coupled human--groundwater prediction using annual pumping-depth data for 43 county-level agents in the High Plains Aquifer Hydrologic Observatory Area within the Ogallala Aquifer. Using the 1993--2020 pumping record, our workflow identifies where pumping behavior departs from stationarity, localizes when these shifts occur, compares stationary and regime-aware data-driven pumping models, and propagates pumping-prediction uncertainty through the Republican River Compact Administration MODFLOW groundwater model. Results show that non-stationarity occurred in a minority of eight agents and was more clearly detected at the county-agent scale than in aggregated cluster means. Regime-aware modeling better captured post-transition pumping-depth trajectories for seven of the eight non-stationary agents. After propagation through the groundwater model, however, improvements were less consistent: regime-aware simulations better represented groundwater-level trajectories for five agents. The coupled simulations show that uncertainty in changing pumping behavior can widen the range of plausible groundwater outcomes over time. These findings identify behavioral non-stationarity as an important source of groundwater-forecast uncertainty and provide a framework for evaluating when coupled human--water models should update behavioral assumptions and propagate behavioral uncertainty.

Agent key

  • 46 county-level RRCA decision units; 43 with complete 1993–2020 records are used.
  • Agent IDs present: {1–32, 36–40, 43–48}; absent: {33, 34, 35, 41, 42}.
  • DTC clusters (k=2): Cluster 2 (minority, high-variability) = {2, 3, 24, 28, 29}; Cluster 1 = the other 38.
  • Non-stationary agents (BOCPD, p ≥ 0.3) = {2, 12, 14, 18, 20, 24, 28, 29} (8 agents). Agent 3 is in Cluster 2 but did not exceed the threshold and is excluded from predictive analysis.
  • Operational changepoints cp*: 2004 (12, 14, 18, 24), 2005 (20), 2011 (29), 2012 (2, 28).
  • TODO (Yao): add the agent-ID → county-name lookup if you want county labels public (not currently in the repo).
