Simulation models are widely used in urban drainage engineering and research. but they are known to include errors and uncertainties that are not yet fully realised. Within the herein developed framework. we investigate model adequacy across multiple sites by comparing model results with measurements for three model objectives. https://www.roneverhart.com/Western-Digital-Ultrastar-DC-HC550-WUH721816ALE6L0-0F38460-16TB-7-2K-RPM-SATA-6Gb-s-512e-ISE-3-5in-Hard-Drive/
