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 colour. 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.
