Is Rain-on-Grid - Or Direct Rainfall - Modelling Accurate?

Explore the accuracy of direct rainfall modeling in this informative webinar presented by Phil Ryan from TUFLOW. Delve into the evolution of rain-on-grid modeling since its mid-2000s introduction, examining its application in urban environments as an alternative to traditional hydrologic modeling approaches. Gain insights into the benchmarking and calibration processes using historic data sets, and discover how TUFLOW's 2020 release addresses previous limitations of 2D hydraulic solvers for rain-on-grid modeling. Compare the efficiency of hydrologic models with the increasing viability of 2D solvers and GPU acceleration in simulating rainfall-runoff processes. Learn about the advantages of faster model setup times and more visually appealing result presentations for stakeholders. Through case studies covering urbanized flood rainfall, high rainfall in large rural areas, and low rainfall in small rural settings, develop a comprehensive understanding of direct rainfall modeling applications and accuracy.
