Reference Solutions and Error Budget for Rainfall-Driven Overland Flow Models
Year: 2026
Type: article
Abstract: This record contains the reference solutions and supplemental materials for the paper "Reference Solutions and Error Budget for Rainfall-Driven Overland Flow Models" by Gurhan Gurarslan (Pamukkale University). Contents 1. Reference solutions (outlet hydrographs sampled every 30 s) for the kinematic, diffusion, and dynamic wave (Saint-Venant) models of overland flow on a plane- Three classical benchmark problems: Example 1 of Kazezyilmaz-Alhan and Medina (2007) and cases A and C of Govindaraju et al. (1990).- A parametric set of 32 configurations: eight bed slopes (F0^2K = 0.07-170), two hyetographs, and zero-gradient and critical-depth outlets.- Uncertainty estimates of the references from mesh refinement. 2. Supplemental materials- Table S1: convergence of the WENO5 scheme.- Table S2: comparison of four reconstructions.- Details on the time-integration error and the computational cost. The reference hydrographs can be used to verify overland flow codes and to separate discretization, model, and outlet-condition errors.
