Short summary

Using two sites with different climates, we show that a 1-pixel version of a distributed hydrologic model that uses a single soil layer with a novel dual-pore structure and employs linear parameterization for infiltration and other fluxes and has comparable performance to a benchmark detailed soil water physics solver in capturing the essential local-scale soil moisture dynamics.
