Method synopsis

High-resolution integrated hydrological modeling using coupled PRMS-MODFLOW system to simulate surface water and groundwater interactions extending 400 m into subsurface. Model accounts for complex terrain, vegetation dynamics, and groundwater-surface water exchange processes.

Synthesized from method descriptions across 15 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Controls from above and below: Snow, soil, and steepness drive diverging trends of subsurface water and streamflow dynamics (2025), Hydrological Processes. The protocol was originally introduced by Depth- and time-resolved distributions of snowmelt-driven hillslope subsurface flow and transport and their contributions to surface waters. (2019), Water Resources Research. Implementations in other papers (listed below) may differ.

1. Configure HBV model
   Set up bucket-type catchment runoff model HBV with standard structure having three outflow paths (surface flow QSF, shallow zone flow QSZ, deep zone flow QDZ). Model determines precipitation phase based on calibrated temperature threshold parameter and simulates snow melt, evapotranspiration, surface and subsurface flow using degree-day approach to calculate snowmelt rates and partition precipitation input between ET and discharge based on water and energy balance.
   Quantities: 3 flow paths, temperature threshold parameter, multiple bucket structuresDuration: 1 year warm-up period followed by calibration periodConditions: Standard HBV model configuration
   Equipment: HBV hydrological model software
2. Calibrate HBV model
   Calibrated HBV for each catchment against measured stream discharge data where available using Genetic Algorithm and Powell optimization tool over 200 calibration trials. Used 1 year of data as warm-up period, then calibrated against 3 continuous years of data. Parameter sets fine-tuned using Powell's quadratically convergent method with combined weighted objective function including NSE, NSElog, KGE, and VE metrics.
   Quantities: 200 calibration trials per catchment, 15 catchments total, 3-year calibration periodsDuration: 3 continuous years calibration period plus 1 year warm-up per catchment
