Internal Renewable Water Resources - Overlap between surface water and groundwater

Topics Water Internal Renewable Water Resources

The United States of America is the top country by overlap between surface and groundwater in the world. As of 2020, overlap between surface and groundwater in the United States of America was 1,227 billion cubic meters per year that accounts for 13.07% of the world's overlap between surface and groundwater. The top 5 countries (others are China, Brazil, Russian Federation, and Colombia) account for 38.58% of it. The world's total overlap between surface and groundwater was estimated at 9,389 billion cubic meters per year in 2020.

Part of the renewable freshwater resources that is common to both surface water and groundwater. It is equal to groundwater drainage into rivers (typically, base flow of rivers) minus seepage from rivers into aquifers
