This book was released on 2011 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract] A 932 ha subcatchment and its associated wetland suite, located in the semi-arid wheatbelt region Western Australia, was investigated in this study. The lower part of the subcatchment exhibits environmental degradation due to altered hydrology resulting from clearing of deep-rooted perennial vegetation. Two main potential threats exist; firstly, upgradient migration of hypersaline groundwater from a regional primary saline valley floor; secondly, increased water and solute loads due to enhanced recharge within the local subcatchment. The hydrological function of the subcatchment and individual wetlands, and uncertainties relating to spatial scales of influence was investigated through combing physical hydrological and hydrochemical methods. A long-term trend of rising groundwater levels within the study area is evident since the clearing of vegetation, and levels have continued to rise since 2006 at about +0.06 m/yr. A ten-fold increase in the TDS at a hyposaline wetland since 1970 indicates active discharge of both stored and replenished water and solutes to the lower catchment. These trends are occurring in spite of a declining regional rainfall trend since the mid 1970's. The aquifers in the lower discharge area appear to be near full capacity although the subcatchment is yet to reach a post-clearing hydrological equilibrium. Significant groundwater TDS and density gradients occur across the study area, increasing rapidly down gradient in both the unconfined and semi-confined aquifers. The ionic compositions of groundwater, surface water and rainfall are dominated by Cl- and Na-, with overall composition being largely proportional to seawater. Cl-/Br- weight ratios indicate that halite dissolution is unlikely to be a primary factor in elevated ionic concentration. Hence, solutes are chiefly sourced from marine-derived aerosols in rainfall. Elevated nutrient concentrations (high N and lower P) were observed, although the absence of algal blooms in wetlands indicates that P is likely a limiting nutrient. Fractionation enriched stable isotopes (eD and e18O) and greater ion concentrations are observed in the deep hypersaline semi-confined aquifer compared to the regional primary saline valley floor aquifer. This indicates the occurrence of reflux brines beneath the hypersaline wetland, resulting in the export of solutes to the underlying aquifers. Seasonal changes in both ionic and stable isotope (eD and e18O) composition within the deep hypersaline semi-confined aquifer further suggest that water and solute exchange is driven by both groundwater head and density gradients. Excess recharge in the upper recharge domain is expressed down gradient at the lower discharge domain as both groundwater discharge and enhanced surface water flows...

Download or read book Biogeochemistry of Wetlands written by K. Ramesh Reddy and published by CRC Press. This book was released on 2022-09-10 with total page 926 pages. Available in PDF, EPUB and Kindle. Book excerpt: The globally important nature of wetland ecosystems has led to their increased protection and restoration as well as their use in engineered systems. Underpinning the beneficial functions of wetlands are a unique suite of physical, chemical, and biological processes that regulate elemental cycling in soils and the water column. This book provides an in-depth coverage of these wetland biogeochemical processes related to the cycling of macroelements including carbon, nitrogen, phosphorus, and sulfur, secondary and trace elements, and toxic organic compounds. In this synthesis, the authors combine more than 100 years of experience studying wetlands and biogeochemistry to look inside the black box of elemental transformations in wetland ecosystems. This new edition is updated throughout to include more topics and provide an integrated view of the coupled nature of biogeochemical cycles in wetland systems. The influence of the elemental cycles is discussed at a range of scales in the context of environmental change including climate, sea level rise, and water quality. Frequent examples of key methods and major case studies are also included to help the reader extend the basic theories for application in their own system. Some of the major topics discussed are: Flooded soil and sediment characteristics Aerobic-anaerobic interfaces Redox chemistry in flooded soil and sediment systems Anaerobic microbial metabolism Plant adaptations to reducing conditions Regulators of organic matter decomposition and accretion Major nutrient sources and sinks Greenhouse gas production and emission Elemental flux processes Remediation of contaminated soils and sediments Coupled C-N-P-S processes Consequences of environmental change in wetlands# The book provides the foundation for a basic understanding of key biogeochemical processes and its applications to solve real world problems. It is detailed, but also assists the reader with box inserts, artfully designed diagrams, and summary tables all supported by numerous current references. This book is an excellent resource for senior undergraduates and graduate students studying ecosystem biogeochemistry with a focus in wetlands and aquatic systems.

Download or read book Stream Hydrology written by Nancy D. Gordon and published by John Wiley & Sons. This book was released on 2013-05-03 with total page 637 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the first edition (1994) there have been rapid developments in the application of hydrology, geomorphology and ecology to stream management. In particular, growth has occurred in the areas of stream rehabilitation and the evaluation of environmental flow needs. The concept of stream health has been adopted as a way of assessing stream resources and setting management goals. Stream Hydrology: An Introduction for Ecologists Second Edition documents recent research and practice in these areas. Chapters provide information on sampling, field techniques, stream analysis, the hydrodynamics of moving water, channel form, sediment transport and commonly used statistical methods such as flow duration and flood frequency analysis. Methods are presented from engineering hydrology, fluvial geomorphology and hydraulics with examples of their biological implications. This book demonstrates how these fields are linked and utilised in modern, scientific river management. * Emphasis on applications, from collecting and analysing field measurements to using data and tools in stream management. * Updated to include new sections on environmental flows, rehabilitation, measuring stream health and stream classification. * Critical reviews of the successes and failures of implementation. * Revised and updated windows-based AQUAPAK software. This book is essential reading for 2nd/3rd year undergraduates and postgraduates of hydrology, stream ecology and fisheries science in Departments of Physical Geography, Biology, Environmental Science, Landscape Ecology, Environmental Engineering and Limnology. It would be valuable reading for professionals working in stream ecology, fisheries science and habitat management, environmental consultants and engineers.

Available in PDF, EPUB and Kindle. Book excerpt: Vegetation communities in Australia's riverine landscapes are ecologically, economically and culturally significant. They are also among the most threatened ecosystems on the continent and have been dramatically altered as a result of human activities and climate change. Vegetation of Australian Riverine Landscapes brings together, for the first time, the results of the substantial amount of research that has been conducted over the last few decades into the biology, ecology and management of these important plant communities in Australia. The book is divided into four sections. The first section provides context with respect to the spatial and temporal dimensions of riverine landscapes in Australia. The second section examines key groups of riverine plants, while the third section provides an overview of riverine vegetation in five major regions of Australia, including patterns, significant threats and management. The final section explores critical issues associated with the conservation and management of riverine plants and vegetation, including water management, salinity, fire and restoration. Vegetation of Australian Riverine Landscapes highlights the incredible diversity and dynamic nature of riverine vegetation across Australia, and will be an excellent reference for researchers, academics and environmental consultants.
