Overview
The size and form of lakes regulate many general transport processes, such as sedimentation, resuspension, diffusion, mixing, burial and outflow. Lakes: Form and Function discusses how much of the variations among lakes in fundamental ecosystem characteristics may be related to lake morphometry, catchment area features, climatological factors and measurement uncertainties. The transport processes regulate many important variables, such as concentrations of phosphorus, suspended particulate matter, pH and color. These variables, in turn, affect primary production, which regulates secondary production, for example of zooplankton and fish. This book discusses such relationships using both empirical data and statistical analyses, and mechanistic principles and models. Researchers and students in limnology, as well as consultants and administrators interested in management and studies of lake systems, will enjoy reading this book.Lars Håkanson received his PhD in Physical Geography from Uppsala University, Sweden. He has written several papers and books related to recent sedimentological processes in lakes, rivers and coastal areas, to mass-balance modelling of radionuclides, nutrients and metals, to aquatic foodweb models and to water pollution.
Synopsis
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
