A Geographic Approach
to Water Data
and Forecasting

Explore stories of how data, science, and location are used to better understand, model, and manage one of Earth’s primary resources: water. At a time when extreme weather events are becoming more frequent and costly, this book demonstrates how innovations in flood forecasting are reshaping our ability to react-specifically, how geographic thinking enhances water science and creates understanding.

From the development of the UC National Water Model to AI-driven real-time flood mapping, disparate layers of georeferenced environmental, demographic, and scientific data can be merged and made meaningful. Scientists, emergency responders, communities, and private citizens rely on this information to anticipate floods, manage drought, and make decisions that can save lives.

This book is part of a new collection based on core geomethods first established in Jack Dangermond's book, The Power of Where. Each chapter focuses on a single spatial methodology, or geomethod: geodata, geovisualization, geocommunication, geocollaboration, geoanalysis, geoaccounting, geoAI, and geodesign.
