Hydrology and Forcing#

How HydroModPy prepares and transfers climatic and recharge-related information toward the groundwater-flow solvers: recharge generation, PyHELP coupling, time aggregation, and the semantics of surface exchange.

Streams and seepage live next door

If you are looking for stream networks, simulated active streams, seepage, or drainage outflow, go to Streams And Seepage instead. The hydrology pages here focus on forcing chains; the streams section focuses on what the model returns at the surface.

Topic pages#

Hydrological forcing chain

End-to-end view of how climatic inputs become recharge and runoff terms consumed by the flow solver.

Hydrological Forcing Chain
Forcing time aggregation

How daily, monthly, and stress-period scales are reconciled before the solver sees them. Includes the first-clim convention.

Forcing Time Aggregation And First_Clim
Recharge and surface exchange semantics

Distinction between recharge, runoff, ETP, and boundary exchange. How the same physical signal can be routed via different package paths.

Recharge And Surface-Exchange Semantics
Stream, ocean, and drainage semantics

Boundary conditions at the groundwater interface: how rivers, oceans, and drainage outlets are represented across backends.

Stream, Ocean, And Drainage Semantics
Simulated active network

Post-solve diagnostic: how stored drainage fluxes are thresholded into a spatial network for comparison with observed hydrography.
