Paperback. Etat : New. Print on Demand. This book presents an in-depth look at the hydrological impacts of the construction of Levee/Canal 31(W) on Taylor Slough, a vital natural drainage system within Everglades National Park. The study, conducted by the National Park Service and the U.S. Geological Survey, provides a comprehensive analysis of data collected before and after the levee's construction, revealing significant changes in the slough's hydrology. The author examines how the levee has affected rainfall, discharge, water levels, and flow patterns, highlighting the impact on the slough's ecology and the broader implications for water management in the Everglades. Through detailed analysis and discussion, this book offers valuable insights into the delicate balance of the Everglades ecosystem and the challenges of preserving its natural integrity. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.

Paperback. Etat : New. Print on Demand. This book explores water quality and nutrient data collected in the Shark River Slough, a critical freshwater ecosystem within Everglades National Park, from 1972 to 1980. The authors utilize various statistical analyses to evaluate seasonal, geographic, and temporal trends in nutrient concentrations, presenting a comprehensive assessment of water quality dynamics in the slough. Despite hydrological alterations in the area, the study reveals that nutrient levels have remained relatively stable thanks to the marsh system's capacity for nutrient retention and the absence of significant point source pollution. The book contributes to the understanding of nutrient cycling and water quality maintenance in freshwater wetlands, emphasizing the importance of preserving these ecosystems for their role in nutrient retention and water filtration.

Paperback. Etat : New. Print on Demand. This book examines the water quality and discharge of the Mowry Canal into Biscayne Bay, Florida, from 1975 to 1981. The author analyzes available data on physical parameters, nutrients, bacteria, heavy metals, and pesticides to assess the canal's impact on the marine habitat of Biscayne National Park. The study reveals a positive relationship between rainfall and discharge, with a significant lag time due to water management practices. While the canal's water quality is generally good, elevated nitrogen levels in one area raise concerns about nutrient loading in the bay. Bacteriological contamination is minimal, and heavy metals and pesticides have been detected in the sediment. The book's insights are crucial for understanding the impact of freshwater discharge on marine ecosystems and the importance of water quality monitoring to protect sensitive coastal environments.
