Book Description
Traditionally, wetlands were considered separately from river basin systems. However, nowadays it is becoming common practice to follow an integrated approach in wetland-riverine watershed analysis and management. Such approach requires not only adequate representations of all relevant bio-physical parameters, but also of socio-political and econom

Book Description
Wetlands are complex and dynamic ecological systems incorporating two important, inter-linked components: hydrology and vegetation. Modelling wetland components and processes reveals the nature of wetland systems and helps to predict the effects of environmental change. The main goal of much current research is the construction of a vigorous and sp

Book Description
The objective of this research is to investigate incorporating a wetland component into a land energy and water fluxes model, the Community Land Model (CLM). CLM is the land fluxes component of the Integrated Global Systems Model (IGSM), a framework that simulates the relationship of physical systems to climate variations. Wetlands play an important role in the storage and regulation of the global water budget so including them in a land water cycle model is found to be necessary in balancing the regional water budgets of simulated river basins. This research focuses on modeling broad hydrological characteristics of wetlands (and lakes) into CLM. CLM's wetland component is reconstructed to reflect a more realistic wetland water budget; it allows for the exchange of water with CLM's river routing component; it allows for varying the storage of wetlands; it allows for calculating discharge from wetlands based on the physics of these ecosystems; and allows the surface water extent of wetlands to vary, a characteristic important to ecological behavior of wetlands and management of wetland ecosystems. The research then implements the modified version of the model for the Sudd wetland, in South Sudan, as it relates to its larger river system, the White Nile. Projects designed to better manage this wetland, such as diverting its inflow to reduce the amount of water consumed by evaporation, are currently under review by its various stakeholders. This diversion stands to change the area of the Sudd, which has direct implications on the ecological and social services derived from the wetland locally. The modified CLM is thus used to provide a better understanding of the science of this management option, and furthers the discussion on the benefits or drawbacks to diversion. Thus, using area as a proxy for environmental impact, what are the environmental, economic and social risks associated with diverting water from inflow into the Sudd? The new wetland component's performance is evaluated against existing observed and modeled data on Sudd hydrology and compared to existing models of the Sudd. The research finds that the potential benefits of diversion cannot be said to unequivocally better the larger system of the White Nile.

Book Description
This book compares the lessons learned from a wetland-perspective approach to the changing climate and the requirements of the Water Framework Directive (WFD) with regard to environmental conservation. Examples from Germany and Poland are discussed due to the efficiency of their respective implementations of water conservation policies. Although the general scientific interest in specific issues such as wetlands, climate change, nature conservation and the WFD enjoy a well established position in international environmental research, these four elements are rarely considered together due to the complexity of the processes, biased scenarios of global change and subjective policy background. Major challenges involved in carrying out environmental conservation actions that assess the potential impacts of climate change and management plans on water bodies are identified. The results of this approach are addressed to practitioners in the field of adaptive management in a wetlands context.

Book Description
Wetland systems involve a complex range of important biological, chemical, and hydrologic interactions among individual wetlands which contribute to ecological health. Modification of the landscape due to anthropogenic development has a direct impact on the connectivity supporting these interactions as well as the ecology of a region. It is thus important for individuals and agencies involved in the management and protection of wetland systems to understand the baseline condition of wetlands, supported interactions, and how potential land use and infrastructure modifications may change the strength of underlying connectivity. This baseline connectivity should, therefore, be rigorously defined, accommodating considerations of different types of connectivity and measurement systems. To better understand these issues, a framework is proposed for representing and reasoning about the connectivity of aquatic resources. In particular, a corridor-based representation of connectivity and network-based optimization methods have been developed and implemented in a geographic information system to establish a baseline level of connectivity and to model the effect of potential landscape changes. The developed framework is applied to a wetland system in Missouri to demonstrate the tradeoff between proposed mitigation options and ease of ensuring sustained system connectivity. More broadly, this type of connectivity analysis can be used to inform many types of planning decisions such as those considering alternative courses of development, prioritization of wetland management/protection resources as well as those addressing policy or regulatory matters.

Book Description
This book is about increasing team performance. It focuses on building system dynamics models when tackling a mix of interrelated strategic problems to enhance team learning, foster consensus, and create commitment. The book is intended to be applied in the organizations of today. As the "command and control" organization evolves into one of decision-making teams, so these teams have become the critical building blocks upon which the performance of the organization depends. The team members face an increased complexity of decision making with the interrelation of several strategic problems. What this means is that people have different views of the situation and will define problems differently. However, research shows that this can in fact be very productive if and when people learn from each other in order to build a shared perspective. Learning in this way might prove to be the only sustainable competitive advantage for organizations in the future. As a result, team leaders want to create "learning teams" and are confronted with issues such as how to: create a situation where people doubt their ideas rather than stubbornly cling to dearly held views create a learning atmosphere rather than trying to "win" the discussion create a shared understanding of a problem in a team foster consensus and create commitment with a strategic decision facilitate Group Model Building Those who will benefit most from Group Model Building: Facilitating Team Learning Using System Dynamics are those who are familiar with systems thinking or organizational learning, or those who are working in groups and are coming up against the common difficulties.
