In contrast to many other works on lake morphometry, the aim of this textbook is to explain how and why morphometry is important to lake ecosystems, particularly in the structure and function of lake foodwebs and in regulating fluxes of substances in lakes. Hakanson (earth sciences, Uppsala U., Sweden) begins with a discussion of echosounding and bathymetric map construction, the means of generating morphometric data, and defines lake morphometric parameters. He then explains the use of lake morphometry for the prediction of key abiotic variables, toxins in fish, and functional groups, as well as for mass-balance modeling and foodweb modeling. Additionally, he discusses the use of geographical information systems for the calculation of morphometric parameters. Annotation 2005 Book News, Inc., Portland, OR (booknews.com)
