Hypsometry of Lakes and Reservoirs

Product Hypsometry

General

The hypsometric curve describes the relationship between water levels and surface areas of a lake or reservoir. In this approach, water levels from satellite altimetry and surface areas from optical imagery are used. This information is essential for the estimation of the time series of volume variations but can also provide important information for hydrological application. Hypsometry of Ray Roberts Lake The right figure shows the hypsometic curve is shown of Ray Roberts as an example. The equation of the hypsometric curve is given below.

Data Holding

DAHITI currently provides 60 hypsometry models distributed over all continents, except Antarctica. In Africa (4 time series), Asia (2), Australia (1), Europe (4), North America (42), and South America (7) water occurrence masks are available. The hypsometry models in DAHITI are freely available and can be downloaded after a short registration process. The amount of hypsometry models is permanently increasing.
