Abstract

Current regulations in California prohibit the disposal of more than 20% fine-grained sediment in the coastal zone; this threshold is currently being investigated to determine if this environmental regulation can be improved upon. A field monitoring and numerical modeling experiment took place late 2 009 to determine the fate of fine-grained dredge disposal material from Santa Cruz Harbor, California, U.S.A. A multi-nested, hydrodynamic-sediment transport modeling approach was used to simulate the direction and dispersal of the dredge plume. Result s show that the direction and dispersal of the plume was influenced by the wave climate, a large proportion of which moved in a easterly direction during wave events. Therefore it is vitally important to accurately simulate the tides, waves, currents, temperature and salinity when modeling the dispersal of the fine-grained dredge plume.

Freshwater and diadromous Fishes of Puerto Rico

Freshwater and Diadromous Fishes of Puerto Rico describes the diversity of fishes in Puerto Rico’s freshwater environments and provides information on the history of research, management and conservation, and culture of fish and fisheries in Puerto Rico. This book’s catalog of fishes guides the reader in the identification of more than 50 native and nonnative species of fish from 22 families that occur in Puerto Rico’s freshwater lagoons, rivers, streams, and reservoirs. Each species account includes a map of known occurrences, and a description of each species’ morphological characteristics, biology, and distribution. Freshwater and Diadromous Fishes of Puerto Rico is the result of decades of scientific research; however, it is intended to be accessible and useful to readers with a variety of backgrounds, including scientists, students, and outdoor enthusiasts such as recreational anglers and freshwater snorkelers. Conservation and management are underlying themes of Freshwater and Diadromous Fishes of Puerto Rico . Though the main goal of this book is to be a resource for the identification of Puerto Rico’s freshwater fishes, and on their biology and ecology, it is also intended to increase awareness of threats to these fishes and their value to people and ecosystems.
