| − | 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 [http://dx.doi.org/10.1016/S0022-1694(96)80014-X "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 1534.9m<sup>2</sup> to 2379.5m<sup>2</sup>, with an average of 2046.0m<sup>2</sup>) to represent the domain [[File:Vcatchmesh.eps.png|thumb|Figure 1: PIHM mesh and domain for the V-catchment.
