Phys.org has written an article covering a study that tests the effectiveness of two different methods of generating flood hazard prediction maps (the runoff-correction method and the lookup method) by comparing their results against historical flood maps.

Using the Chi-Mun River in Southeast Asia and the Amazon River in South America as the test cases, researchers found that both methods successfully predicted increased flooding hazards for the Chi-Mun, but the lookup method was more accurate for the Amazon. The study’s results highlight the importance of checking new modeling methods against historical data in order to create stronger predictive results. Read more at Phys.org.
