Developing a Service-Learning Program for Watershed Management: Lessons from the Stroubles Creek Watershed Initiative

de Leon, Raymond F. 09 May 2002 (has links)
There has been a growing interest and support by many state and local programs to address aquatic resource protection and restoration at a watershed level. The desire by many programs to implement watershed management programs has become more than just a need, rather a necessity to ensure suitable water resources. However, many challenges arise when developing and sustaining watershed programs. One such challenge is that watershed programs are resource intensive. These programs require significant funds to support monitoring, research, effective management, and to provide public outreach. In addition, these programs require knowledgeable and skilled water resource professionals who can implement and manage these tasks. Integrating university-knowledge and resources into the watershed effort can meet many of these challenges. Faculty, students, and in-kind university support can contribute knowledge, technical support, research funds, and personnel to aid and enhance watershed management activities. Furthermore, connecting watershed management activities with academic work can foster the development of future environmental planning, policy, and science professionals. The overall goal of this paper is to explore the integration of service-learning in higher education within watershed management activities. The concepts and benefits of service-learning are explored in this paper. An example of a watershed-based, service-learning initiative in the Stroubles Creek watershed, Virginia is presented. In addition, perspectives gathered from the Initiative's students and project coordinator (the author) on their work experience as service-learners are provided. The lessons and recommendations presented in this paper pave way to means of sustaining and enhancing service-learning program in watershed activities. / Master of Urban and Regional Planning

"Storm", a Mathematical Model Applied to the Shingle Creek Basin

Foy, Jay G. 01 January 1975 (has links) (PDF)
Stormwater management necessitates a regional plan based on the best practical methods. "Storm", a mathematical model, is employed to simulate runoff conditions in the Shingle Creek Basin. The computed runoff quantity is calibrated directly with the streams hydrograph. Runoff quality is predicted with two sets of pollutant loading rates. The scope of the model is expanded by development of parametric curves that can be used to convert measured quality data to input land use loadings. A parametric study is also performed to fabricate the effects of urbanization on the Shingle Creek Basin.

Epikarst control on flow and storage at James Cave, VA: an analog for water resource characterization in Shenandoah Valley karst

Gerst, Jonathan Daniel 12 August 2010 (has links)
Karst aquifers host significant water supplies but are easily contaminated because highly conductive inlets can rapidly transmit water to depth. The epikarst, which is the region of vegetation, soil, and weathered bedrock above karst aquifers, is a critical zone as it regulates the quantity and quality of recharge to the aquifer. As the epikarst exhibits complex heterogeneity, characterization at the field scale can be challenging. The objective of this thesis was to develop a model of epikarst hydrodynamics using longterm field measurements. To meet this objective, continuous hydrologic data of precipitation, speleothem drips, and an underground stream in James Cave in Pulaski County, VA, were collected to delineate seasonal recharge patterns, estimate effective recharge and catchment areas, characterize the number and permeability of flow paths, and evaluate storativity in the epikarst. Results demonstrate that after significant seasonal recharge, which occurs in the late winter and early spring, the epikarst can temporarily store a significant portion of recharge in low permeability flow paths. Effective recharge was estimated to be approximately 30% of total precipitation (2008-2009). Hydrograph recession analysis aided in delineation of flowpaths in the epikarst, including quickflow, moderate flow, and baseflow components. Hydrograph shape analysis suggests flow restrictions at two of the drip sites that may reveal spatial differences in storage capacity and retention time. Results of this work are intended to aid karst aquifer management by providing a multitechnique approach that can be used to assess seasonal patterns of recharge, quantify flowpath and storage characteristics, and delineate recharge zones. / Master of Science

Choice of multicriterion decision making techniques for watershed management

Tecle, Aregai,1948- January 1988 (has links)
The problem of selecting a multicriterion decision making (MCDM) technique for watershed resources management is investigated. Of explicit concern in this research is the matching of a watersned resources management problem with an appropriate MCDM technique. More than seventy techniques are recognized while reviewing the area of MCDM. A new classification scheme is developed to categorize these techniques into four groups on the bases of each algorithm's structural formulation and the possible results obtained by using the algorithm. Other standard classification schemes are also discussed to better understand the differences and similarities among the techniques and thereby demonstrate the importance of matching a particular multicriterion decision problem with an appropriate MCDM technique. The desire for selecting the most appropriate MCDM technique for watershed resources management lead to the development of 49 technique choice criteria and an algorithm for selecting a technique. The algorithm divides the technique choice criteria into four groups: (1) DM/analyst-related criteria, (2) technique-related criteria, (3) problem-related criteria and (4) solution-related criteria. To analyze the applicability of MCDM techniques to a particular problem, the levels of performance of the techniques in solving the problem are, at first, evaluated with respect to the choice criteria in each criterion group resulting in four sets of preference rankings. These four sets are then linearly combined using a set of trade-off parameters to determine the overall preference ranking of the techniques. The MUM technique selection process is itself modeled as a multiobjective problem. In this research, for example, a set of 15 techniques, the author is familiar with, are analyzed for their appropriateness to solve a watershed resources management problem. The performance levels of the 15 MCDM techniques in solving such a problem are evaluated with respect to a selected set of technique choice criteria in each criterion group leading to a set of four evaluation matrices of choice criteria versus alternative techniques. This technique choice problem is then analyzed using a two-stage evaluation procedure known as composite programming. The final product of the process resulted in a preference ranking of the alternative MCDM techniques.

Assessing the Influence and Effectiveness of Watershed Report Cards on Watershed Management: A Study of Watershed Organizations in Canada

Veale, Barbara January 2010 (has links)
The concept and practice of watershed management have evolved since the early twentieth century and continue to change. Contemporary watershed management, as a means to improve environmental, social, and economic well-being, is generally accepted world-wide and is gaining popularity. Recognition of the ever-changing, complex, conflicting, and unpredictable nature of the forces that influence ecological and human systems has given rise to concepts and principles related to ecological or watershed health, sustainability, and good governance. Numerous terms have emerged to describe and explain contemporary watershed management processes that incorporate these concepts and principles, including ‘integrated’ and ‘sustainable’ watershed management. While there is growing consensus that integrated or sustainable watershed management should be practiced, there is little agreement on what these two terms mean and how they differ. The rational comprehensive or synoptic model is a widely-accepted normative framework to guide watershed management processes. This model presumes a ‘top-down’ linear, systematic, and logical sequence of steps characterized by complete knowledge of the issues and consequences of actions and dominated by rational decision making – circumstances that rarely happen in real life. Implementation gaps between theory and practice exist because of persistent and common challenges relating to complexity, conflict, uncertainty, and change in human and ecological systems. Failure to account for these factors has restricted the utility of this model for guiding watershed management processes, prompting questions about how the model might be adjusted to incorporate concepts and principles associated with watershed health, sustainability, and good governance. In response to the need to demonstrate progress towards watershed health and sustainability, a growing number of watershed organizations in Canada are pioneering the development of indicator-based assessment reports. The actual versus anticipated outcomes of watershed indicator reports and their existing and potential role in the watershed management process have not been systematically assessed or compared. A review of academic and professional literature and a mixed methods research approach comparing 13 case studies from 7 provinces across Canada were used to explore these knowledge gaps. A more in-depth investigation of two of the case studies, the Fraser Basin Council and the Humber Watershed Alliance, was also completed. Contextual factors influencing the practice of watershed management and the process used for developing watershed report cards are identified through an analysis of available documents. This information is supplemented with opinions gathered from 109 in-depth and semi-structured interviews/questionnaires. In addition, informants provided viewpoints regarding the usefulness, effectiveness, benefits, and value of watershed report cards, along with ideas about how they can be improved. This study concludes that while sustainable watershed management (SWM) and integrated watershed management (IWM) are closely aligned concepts, the distinguishing factor is scope. The primary goal of SWM is environmental, social, and economic sustainability within a watershed unit, whereas the central focus of IWM is the protection and/or restoration of water and land resources within a watershed to sustain human well-being. In Canada, IWM rather than SWM is generally pursued. Nevertheless, sustainability is an ultimate goal of IWM. Sustainability principles are acknowledged, valued, and applied. This study concludes that IWM can play a significant role in supporting a broad sustainability agenda. This study contributes to a growing body of knowledge seeking to enrich the theory of watershed management and improve and streamline practice. To improve the utility of the rational comprehensive model for guiding contemporary watershed management, modifications are presented which include separate phases for visioning and learning and couch the process within an overall conceptual framework that balances management, research, and monitoring activities. These adjustments reflect the concepts of integration, collaboration, and shared learning and acknowledge the shift away from ‘command and control’ bureaucratic processes to collaborative ‘middle ground’ polycentric governance structures. Rather than focusing strictly on a sequence of steps and a prescribed process, the consideration of a series of context-specific questions is advocated to help scope and streamline processes to match stakeholder capacity, address issues of greatest concern, and sustain interest and enthusiasm. However, concerted effort is required to counteract competing and entrenched socio-political and economic doctrines and traditions. Monitoring, evaluating, and reporting are key components in the IWM process. Study findings reveal that watershed report cards in Canada are a fledgling tool and no standard approach exists. Each case-study watershed organization has a unique approach to selecting, organizing, and presenting indicators. As a result, report card styles and formats vary. Despite a general consensus that watershed report cards are worthwhile, expectations often exceed outcomes, and common traits which challenge their effectiveness exist. The usefulness and effectiveness of watershed report cards are hampered by several common shortfalls: (1) universal lack of consistent, spatially-specific, and timely data, (2) inconsistent measures and indicators between successive watershed reports, (3) ambiguous or non-existent goals, objectives, targets, and benchmarks, and (4) messages that are unclear, difficult to understand, or fail to resonate with the target audiences. The ‘lessons learned’ from an assessment of the attributes and perceived benefits of watershed report cards parallel those discovered for community indicator initiatives. Building on this research, recommendations for improvement include (1) focus on stakeholder issues of prime concern, (2) use consistent measures and indicators, (3) limit the number of indicators and simplify report card styles and formats, (4) select spatially explicit, temporally relevant, and science-based indicators and measures, (5) explain and illustrate major cause-effect linkages, (6) use the report card process to build a constituency of support, (7) incorporate marketing and outreach activities, and (8) introduce performance measures to assess efficiency and how well collective practice demonstrates sustainability principles. This study concludes that opportunities exist for improving watershed report cards and boosting their multi-purpose role as a predominant planning, assessment, advocacy, communication, learning, and research tool in support of IWM, and ultimately, sustainability.
