AquaScope unifies 20 global water-data sources behind one Python schema, then layers a full scientific computing stack on top — from Bulletin 17C flood frequency to FAO-56 crop water requirements — wrapped in an AI engine that scores 26 research methodologies against your dataset and auto-executes 7 analysis pipelines. Validated against the CAMELS benchmark with 820+ tests.

🚀 Examples

1. Flood frequency analysis (Bulletin 17C)

from aquascope.api import flood_analysis

result = flood_analysis(daily_discharge, method="gev", return_periods=[10, 50, 100])
print(result.return_levels)
#   return_period  return_level  lower_ci  upper_ci
# 0           10        1840.2     1690.4    2010.6
# 1           50        2530.7     2280.1    2820.9
# 2          100        2870.4     2540.6    3260.5

Switch method to "lp3", "gumbel", "gpd", or "ns_gev" for non-stationary analysis. Pass censored=True for EMA on records with peak-over-threshold gaps.

2. Baseflow separation + hydrological signatures

from aquascope.api import baseflow_analysis, compute_all_signatures

bf  = baseflow_analysis(daily_discharge, method="eckhardt")   # or "lyne_hollick"
sig = compute_all_signatures(daily_discharge)

print(bf.bfi)                  # baseflow index, e.g. 0.42
print(sig["Q5"], sig["Q95"])   # high-flow / low-flow exceedances
print(sig["flashiness"])       # Richards-Baker flashiness index

22 signatures across magnitude, variability, timing, recession, and flashiness — see docs/features.md.

3. Collect data from any of the 20 sources

from aquascope.collectors import USGSCollector, AquastatCollector, WaporCollector

usgs = USGSCollector()
flow = usgs.collect(station_id="01646500", parameter="00060", days=365)

aquastat = AquastatCollector()
egy_water = aquastat.collect(country="EGY", variables=[4263, 4253, 4312])

wapor = WaporCollector()
et = wapor.collect(
    bbox=(30.5, 29.8, 31.1, 30.2),
    variable="RET",
    start_date="2026-04-01",
    end_date="2026-07-31",
)

Every collector returns records in the same Pydantic schema, so downstream analyses don't care where the data came from. See docs/data_sources.md for the full list.

4. FAO-56 crop water requirements + soil water balance

from datetime import date
from aquascope.agri import (
    penman_monteith_daily,
    crop_water_requirement,
    SoilWaterBalance,
)
from aquascope.agri.water_balance import SoilProperties

# Reference ET (FAO-56 Penman-Monteith) — Cairo, July
eto = penman_monteith_daily(
    t_min=18.0, t_max=32.0, rh_min=40, rh_max=80,
    u2=2.0, rs=22.0, latitude=30.0, elevation=70, doy=180,
)

# Crop water requirement for maize from planting through harvest
cwr = crop_water_requirement(eto_series, crop="maize", planting_date=date(2026, 4, 1))

# Soil water balance with auto-irrigation triggers — returns a daily DataFrame
soil    = SoilProperties(field_capacity=0.30, wilting_point=0.15, root_depth=1.0)
balance = SoilWaterBalance(soil).auto_irrigate(
    cwr["etc"], precip_series, efficiency=0.7,
)
print(balance["irrigation_mm"].sum())             # total irrigation applied (mm)
print(int(balance["irrigation_trigger"].sum()))   # number of deficit days

5. AI methodology recommender

from aquascope.ai_engine import recommend

# Describe your dataset and goal — get ranked, scored methodologies
recs = recommend(
    parameters=["DO", "BOD5", "COD"],
    n_records=4_500,
    temporal=True,
    spatial=False,
    goal="detect long-term pollution trends with seasonality",
)

for r in recs[:3]:
    print(f"{r.score:.2f}  {r.method_id:<20}  {r.rationale}")
# 0.92  mann_kendall          Strong fit: temporal data, >30 records, trend goal
# 0.87  stl_decomposition     Seasonal patterns + multi-year data
# 0.81  prophet               Forecasting-capable, handles seasonality natively

Then auto-execute the top result with run_pipeline(recs[0].method_id, df).

6. Change-point detection + copula dependence

from aquascope.api import detect_changepoints, fit_copula

cps  = detect_changepoints(annual_runoff, method="pettitt")
cop  = fit_copula(rainfall, runoff, family="auto")    # AIC-selects Gaussian/Clayton/Gumbel/Frank
print(cps.change_year, cps.p_value)
print(cop.family, cop.theta, cop.aic)

7. Bayesian regression with uncertainty quantification

from aquascope.api import bayesian_regression

# Annual rainfall → runoff with full posterior + convergence diagnostics
posterior = bayesian_regression(X=annual_precip, y=annual_runoff)

print(posterior.posterior_mean)
# {'beta_0': 12.4, 'beta_1': 0.82, 'sigma2': 41.6}

print(posterior.credible_intervals["beta_1"])
# (0.78, 0.86)        ← 95% credible interval on slope

print(posterior.r_hat)
# {'beta_0': 1.00, 'beta_1': 1.00, 'sigma2': 1.00}    ← Gelman–Rubin, converged

print(posterior.dic, posterior.effective_sample_size["beta_1"])
# 124.7  9842.0       ← model fit + effective sample size

Switch to MCMC with degree>1 for polynomial models, or pass prior_precision for informative priors. Conjugate linear, polynomial, and Metropolis-Hastings backends are all available.
