Book Description
Of all the natural resources that bless the United States, none is more important than its water. The nation's rivers and streams provide vital navigation links, hydropower, fishing, recreation, and water for domestic, agricultural, and industrial use. At the same time, they occasionally overrun towns and farms, destroy property, threaten livelihoods, and take lives. Perhaps nowhere in the country have the conflicting purposes of water development stimulated more studies, engineering responses, and public involvement than in Louisiana's Atchafalaya Basin-which includes the largest river basin swamp in North America. Since the early nineteenth century, all levels of government have been involved. The U. S. Army Corps of Engineers' part in the basin's development includes providing flood control and maintaining navigable channels. Today, the Atchafalaya Basin serves as a major floodway to convey Mississippi River water to the Gulf of Mexico. In this history, Dr. Reuss tells the complicated, but fascinating story of how local, state, and federal agencies have attempted to reconcile conflicting visions for the basin. In so doing, he illuminates the interaction of politics, technology, and environment. Though focusing on one area of the country, this book addresses many themes associated with the development of water resources throughout the United States.

Book Description
The Atchafalaya River Basin (ARB) in Louisiana is the principal distributary of the Mississippi River, and it contains the largest contiguous area of baldcypress-water tupelo swamp forests in North America. After designation of the ARB as a federal floodway following the destructive 1927 Mississippi River (MR) flood, it was extensively modified to accommodate a substantial portion of the MR flow (~30%) to mitigate flooding in southern Louisiana. The resulting reach to system scale modifications for regional flood mitigation, navigation, and hydrocarbon extraction have substantially altered the lateral connectivity between the AR and its floodplain wetlands, threatening the ecological integrity of this globally-important ecosystem. Multiple stakeholder groups agree that restoring flow connectivity is essential to maintaining the basin's water quality and forest health, and several flow-connectivity enhancement projects (hereafter, project elements) have been proposed by the Atchafalaya Basin Program's Technical Advisory Group within the Flat Lake Water Management Unit (FLWMU) study area to increase lateral hydrologic connectivity within the management unit and beyond. Additionally, a new flow prescription to improve floodplain habitat has recently been suggested for the ARB. Flow into the ARB is now regulated through the Old River Control Structure (ORCS; operational in 1963), and represents the opportunity for large-scale flow experiments to enhance a multitude of ecosystem services that have been degraded due to anthropogenic alteration. For this study, I compiled existing datasets and constructed a 1D2D hydraulic model to evaluate: 1) if the suggested flow prescription would have the desired inundation impacts; 2) whether the proposed project elements would improve lateral connectivity in the FLWMU; and 3) whether recommended project elements would increase the area suitable for baldcypress recruitment in the study area. I examine the first two research questions above, I examined two scenarios--a baseline scenario to examine current conditions (no restoration projects), and a full-implementation scenario, where all proposed project elements that could be examined at the model resolution were implemented. Comparison of the modeling results for the baseline scenario to the suggested flow prescription goals suggests the overbank discharge and the extreme low-flow targets would have the desired impacts of inundating and drying out of the majority of the FLWMU, respectively. Proxy indicators of enhanced flow connectivity suggest that proposed projects will improve water quality, especially at intermediate to high flow conditions, when ~90% of the FLWMU experiences improved drainage as indicated by higher rates of water surface elevation decrease and lower overall system water volume. The stated objectives of the project elements recommended by the Technical Advisory Group are to improve connectivity and water quality, but another important and related restoration goal for stakeholders includes baldcypress restoration. To examine the third objective, I used a model-derived proxy indicator of habitat improvement (depth reduction) at two key discharges, along with other ecological suitability factors, to determine areas most likely to support baldcypress recruitment. Here, I compared baseline conditions to two alternative restoration scenarios: 1) a targeted implementation scenario where 22 project elements were implemented, and 2) the full-implementation scenario, where all projects that could be examined at the model resolution were implemented. Suitable habitat area for both natural and artificial baldcypress recruitment increased under intermediate flow conditions but remained unchanged for higher discharge conditions. For the intermediate discharge scenario, the full-implementation scenario results in a 2 km2 increase in the class considered most suitable for natural baldcypress regeneration within the calculated recruitment band, and a decrease of ~16 km2 in the areas considered least suitable for the entire FLWMU study area. Coupled with the connectivity results, which indicate that nutrient-rich river water will be exchanged between main channels and the backswamp at a greater range of flows, it appears that project implementation alone will benefit baldcypress recruitment, especially artificial regeneration efforts. However, full project implementation coupled with large-scale flow modifications at ORCS would likely provide maximum benefit for baldcypress restoration efforts that seek to increase the area supportive of natural baldcypress regeneration.

Book Description
This book contains the proceedings of a symposium held at the College of Charleston, Charleston, South Carolina, USA, 16-20 June 1986. The seed for this symposium arose from a group of physiologists , soU scientists and biochemists that met in Leningrad, USSR in July 1975 at the 12th Botanical Conference in a Session organized by Professor B.B. Vartepetian. This group and others later conspired to contribute to a book entitled Plant Life in Anaerobic Environments (eds. D. D. Hook and R. M. M. Crawford, Ann Arbor Science, 1978). Several contributors to the book suggested in 1983 that a broad-scoped symposium on wetlands would be useful (a) in facilitating communication among the diverse research groups involved in wetlands research (b) in bringing researchers and managers together and (c) in presenting a com prehensive and balanced coverage on the status of ecology ami management of wetlands from a global perspective. With this encouragement, the senior editor organized a Plan ning Committee that encompassed expertise from many disciplines of wetland scientists and managers. This Committee, with input from their colleagues around the world, organized a symposium that addressed almost every aspect of wetland ecology and management.

Book Description
Forty-two chapters by international experts from a wide range ofdisciplines make The Wetlands Handbook the essential toolfor those seeking comprehensive understanding of the subject. Adeparture from more traditional treatises, this text examinesfreshwater wetland ecosystem science from the fundamentals toissues of management and policy. Introductory chapters address the scope and significance ofwetlands globally for communities, culture and biodiversity.Subsequent sections deal with processes underpinning wetlandfunctioning, how wetlands work, their uses and values for humansand nature, their sensitivity to external impacts, and how they maybe restored. The text is illustrated by numerous examples,emphasising functional and holistic approaches to wetlandmanagement, including case studies on the wise use andrehabilitation of wetlands in farmed, urban, industrial and otherdamaged environments, highlighting the long-term benefits ofmultiple use. The Wetlands Handbook will provide aninvaluable reference for researchers, managers, policy-makers andstudents of wetland sciences.
