Nutrient enrichment of lakes is a ubiquitous problem, impacting
ecological and human health on a global scale by accelerating the pace
of eutrophication, often resulting in algal blooms, depleted dissolved
oxygen concentrations, and economic harm to surrounding communities. In
many lakes, bed sediments are a major but unrecognized source of
phosphorus to the water, a process known as internal phosphorus loading.
Internal loading is notoriously difficult to measure and manage given
the need to access processes operating on and within the lakebed. In
addition, climate change threatens to promote internal loading. For
example, warming of lakes can increase the release of phosphorus from
sediments due to 1) longer and stronger periods of lake stratification
resulting in sediment anoxia and 2) enhanced microbial decomposition of
organic matter. Degraded water quality not only impairs ecological
health but also can influence social pride and community morale. This is
the first book dedicated to the understanding of internal phosphorus
loading in lakes and examines the causes, the ecological and societal
impacts, and options for managing this complex phenomenon. With
contributions from leading experts, this edited volume provides a broad
view of internal phosphorus loading, methods for measurement, management
practices for water quality improvement, case studies from around the
world, and recommendations for addressing this growing concern. It is
essential reading for environmental and engineering professionals
involved in lake and reservoir management, students and faculty in
limnology, state and federal authorities involved in water quality
regulation, and lakefront homeowners and management boards interested in
maintaining lake water quality and managing algal blooms. Key Features -
