Researchers out of UC Irvine say nationally used flood modeling lacks specificity when it comes to measuring risks in urban areas like Los Angeles County. They've created their own modeling system, PRIMo-Drain, that can better predict which properties are at risk when using accurate, granular data. … In a new report, UCI engineering professor Brett Sanders and his team compared widely used national flood risk assessment modeling in areas like Los Angeles County against their own PRIMo-Drain model. … “Once we have this relatively detailed representation of the land surface, of the flood infrastructure, we look at different types of flooding,” Sanders said.
