Incorporated models or components:
Spatial dimensions
Spatial extent Watershed-Scale
Model domain Terrestrial, Hydrology
One-line model description Linear-reservoir hydrological model with snowpack and evapotranspiration
Extended model description RaVENS: Rain and Variable Evapotranspiration, Nieve, and Streamflow

Simple "conceptual" hydrological model that may include an arbitrary number of linked linear reservoirs (soil-zone water, groundwater, etc.) as well as snowpack (accumulation from precipitation with T<0; positive-degree-day melt) and evapotranspiration (from external input or Thorntwaite equation).

It also includes a water-balance component to adjust ET (typically the least known input) to ensure that P - Q - ET = 0 over the course of a water year.

Other components plot data and compute the NSE (Nash–Sutcliffe model efficiency coefficient).
