discharge_evaluation

Evaluate simulated discharge against observed gauge discharge.

The module loads model and observation time series, matches gauges to simulation outputs, optionally optimizes gauge locations with flow-accumulation data, and computes direct or bootstrapped discharge metrics with hydrograph diagnostics.
