Any Available Datasets For Street Flood Levels?

Hi! I’m currently a 3rd year Computer Science student conducting a thesis about forecasting street floods using a machine learning model in real time. I’m currently having a hard time finding publicly available historical time-series datasets that records flood depths on urban street areas. I’ve tried Kaggle, the Google search engine for datasets, and even NASA’s Earth Data website to no avail.

I’m starting to become really worried that I might not be able to find the dataset I need to actually conduct this research. I’m planning on asking government agencies soon and other academic institutions, and see where that takes me. In the meantime, do you guys know anywhere else I could gather data for this? Do you also have any suggestions of the possible steps that I could take as a contingency plan if ever the data is actually non-existent?

Thanks!
