Book Description
The aquatic macroinvertebrate assemblage of a dike in the Lower Mississippi River was evaluated by implanting substrate basket samplers into the structure. The resulting data indicated that a diverse (38 taxa) and productive (average density = 101,968.4 organisms/sq. m assemblage was present, and was characterized by net-spinning caddisflies, tube-building chironomids, clinging mayflies, and isopods. A comparison of the surface stones of the basket samplers with adjacent surface stones of the dike indicated that the implanted substrates provided representative estimates of both the composition and structure of the macroinvertebrate assemblage. These data also indicated significant macroinvertebrate activity below the surface substrate of the dike. Differences in habitat conditions among dike positions (downstream, top, upstream) were the major contributors to overall sample variability. Thus, stratified random sampling based on dike position is recommended for future comparative studies. (Author).

Urban Stormwater Management in the United States

Pages : 611
Book Description
The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.
Groundwater-Surface Water Interactions

Book Description
Recent years have seen a paradigm shift in our understanding of groundwater–surface water interactions: surface water and aquifers were long considered discrete, separate entities; they are now understood as integral components of a surface–subsurface continuum. This book provides an overview of current research advances and innovative approaches in groundwater–surface water interactions. The 20 research articles and 1 communication cover a wide range of thematic scopes, scales, and experimental and modelling methods across different disciplines (hydrology, aquatic ecology, biogeochemistry, and environmental pollution). The book identifies current knowledge gaps and reveals the challenges in establishing standardized measurement, observation, and assessment approaches. It includes current hot topcis with environmental and societal relevance such as eutrophication, retention of legacy, and emerging pollutants (e.g., pharmaceuticals and microplastics), urban water interfaces, and climate change impacts. The book demonstrates the relevance of processes at groundwater–surface water interfaces for (1) regional water balances and (2) quality and quantity of drinking water resources. As such, this book represents the long-awaited transfer of the above-mentioned paradigm shift in understanding of groundwater–surface water interactions from science to practice.
