HighTide’s peer-reviewed methodology

We believe in being transparent about our methods and usage of cutting-edge science. We are thrilled to share our methodology for calculating the economic and socioeconomic impacts of present and future flooding, published on July 2021 in Earth’s Future.

At Stanford, we lovingly referred to our model as SURF, the Stanford Urban Risk Framework. For the past two years, we’ve expanded on SURF’s technology to bring you the  HighTide Flood Risk Engine.
