Make data accessible by Xuan Yu

Details on how to do this task: Make data accessible

PIHM has been validated by the V-catchment. Here we prepared the input files for the V-catchment simulation. The V-catchment is benchmark example for the 2-D overland surface flow coupled with channel routing "P. Di Giammarco et al., 1996". In the benchmark example, a rainfall event of 90-minute duration, 3e-6 m/s is applied on the V-catchment. The runoff at the outlet is usually compared for model validation. In this section, we shows how to use PIHM simulate the rainfall-runoff response of the V-catchment. PIHM uses triangular mesh to represent the domain. The grid resolution may vary. Here, we used 782 triangles ( the area ranges from 1534.9m² to 2379.5m², with an average of 2046.0m²) to represent the domain

The data is from the experiment in 1974, at Shale Hills, PA
