"Storm", a Mathematical Model Applied to the Shingle Creek BasinFoy, 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.

Analysing Water Governance: A Tool for SustainabilityFranks, Tom R., Cleaver, Frances D. January 2009 (has links)
yes / Managing global water resources and providing water services to the world¿s people raises a continuing series of challenges, driven by increasing expectations, and a growing competition for water, which will be exacerbated by climate change. This paper explores how concepts of water governance and sustainability may help us to meet those challenges. Water governance is often equated with the role of government or management in the provision of water services. By contrast, we see governance as the system of actors, resources, mechanisms and processes, which mediate society¿s access to water. A broad conceptual framework is presented for the analysis of water governance, based on linkages between the resources available to society, the mechanisms that shape access to water and the outcomes of those mechanisms, both for people and the ecosystem. These linkages are mediated both by stakeholders and by management processes. It is argued that this conceptual framework offers a robust analytical tool for planning for sustainability as it is able to account for the complexities of water governance (of contexts, stakeholders, arrangements and uses). The paper concludes with observations about the ways in which the framework can be used to understand how different water governance arrangements produce variable outcomes in terms of sustainability.

Optimization of Multi-Reservoir Management Rules Subject to Climate and Demand Change in the Potomac River BasinStagge, James Howard 07 August 2012 (has links)
Water management in the Washington Metropolitan Area (WMA) is challenging because the system relies on flow in the Potomac river, which is largely uncontrolled and augmented by the Jennings-Randolph reservoir, located 9-10 days travel time upstream. Given this lag, release decisions must be made collectively by federal, state and local stakeholders amid significant uncertainty, well in advance of accurate weather forecasts with no ability to recapture excess releases. Adding to this uncertainty are predictions of more severe and sporadic rainfall over the next century, caused by anthropogenic climate change.
This study aims to evaluate the potential impacts of demand and climate change on the WMA water supply system, identifying changes in system vulnerability over the next century and developing adaptation strategies designed to maximize efficiency in a nonstationary system. A daily stochastic streamflow generation model is presented, which succesfully replicates statistics of the historical streamflow record and can produce climate-adjusted daily time-series. Using these time series, a multi-objective evolutionary algorithm is used to optimize the system's operating rules given current and future conditions, considering several competing objectives. / Ph.

Water governance and poverty: a framework for analysisFranks, Tom R., Cleaver, Frances D. 10 1900 (has links)
Yes / This paper engages with policy on meeting development goals for water through interventions which promote good governance. Addressing an under-researched area, we propose a new analytical framework for understanding water governance, not as a set of abstract principles, but as interlinked processes with variable practical outcomes for poor people. The framework is informed by theories of governance, institutions and structuration, empirical research and field insights. We apply the framework to a case in Southwestern Tanzania, and we identify a range of issues for further research, particularly relating to water access for the poor.

Water governance and poverty: a framework for analysisCleaver, Frances D., Franks, Tom R. 12 1900 (has links)
Yes / In this paper we present a framework for understanding water governance, through which we
critique some of the assumptions underlying the current consensus on good governance.
Specifically, we suggest that current approaches are based on incomplete or partial
understandings of the concepts of governance. We question the idea that governance can be
identified as an abstract set of principles, without the need for contextualisation and localisation.
In particular, we suggest that there is a general lack of understanding of the way local
interactions shape and influence governance processes. Finally, and with specific reference to
the MDGs and the water sector, we question the implicit assumption that `good¿ governance is
necessarily pro-poor governance.
The paper addresses these issues through a critical discussion of governance, from which we
develop a framework for conceptualising water governance. The framework draws on theories of
governance, institutions and structuration, but is also informed by recent empirical research and
experiences from the field. We apply the framework to a specific case in Southwestern Tanzania
and raise a number of issues and challenges for further research.

THE QUANTITATIVE FEATURES OF CHINA'S WATER RESOURCES: AN OVERVIEWChangming, Liu 02 1900 (has links)
China has a long history of hydrological development. According to
Chinese legends, famous projects of flood water diversion were developed by
the Great Yu as early as the year two thousand B.C. The earliest hydrological
record appeared in 256 B.C., when Mr. Lipin and his son constructed
the Dujiangyan irrigation system in the upper reach of the Mingjiang River
in Sichuan Province. At Baopingkao, the water intake point of the
Dujiangyan irrigation system, a water staff gage was carved on a stone for
the measurement of water levels. Although hydrological studies in China
started early, hydrology and water resources as modern sciences have been
developed only in the last several decades, particularly rapidly in the last
30 years. For instance, the number of hydrological stations has increased
45 times, from about 350 to more than 16,000. Of these, about 3300 stations
also take flow velocity measurements. The average density of the hydrological
stations is about one per 530 km2 and that of discharge measurement
stations about one in 3,000 km2. These stations are highly concentrated in
eastern China. The longest records of precipitation are maintained in the
large cities in eastern China, including Beijing, Shanghai and Tianjing.
Beijing has 140 years of precipitation records. The Hankao hydrological
station on the Changjiang (Yangtze) River has the longest discharge record
spanning 117 years (1865- 1982).

DESIGN OF WATER RESOURCES SYSTEMS IN DEVELOPING COUNTRIES: THE LOWER MEKONG BASINChaemsaithong, Kanchit 06 1900 (has links)
This study focuses on the design of water resources
systems in developing nations with particular reference to
the development of water resources in the Lower Mekong
Basin (Khmer Republic, Laos, Thailand, and Republic of
South Viet -Nam). The determination of the "best" system
in terms of social goals reflecting the economic and social
environment of the Mekong countries is the main issue of
this dissertation.
The imperfection of the usual technique for planning
water resources systems, namely, cost -benefit analysis,
leads to the use of the standardized cost -effectiveness
methodology. To illustrate how the design is accomplished,
two distinctly different structural alternatives of possible
development in the Lower Mekong Basin are defined. The
design process starts from the statements of goals or
objectives of water resources development, which are then
mapped onto specifications sets in which social needs are
represented. Next, the capabilities of alternative systems
are determined through simulation in which three 50 -year
sequences of synthetic streamflow are generated by a first
order autoregressive scheme.
The two alternatives are then compared using both
quantitative and qualitative criteria. To illustrate how a decision in selecting an alternative system could be
reached, ranking of criteria by order of preference is
demonstrated. With the choice of either a fixed -cost or
fixed- effectiveness approach, the decision to select the
best alternative system could be made. At this point, the
use of a weighting technique, which is a common fallacy of
systems analysis, will be automatically eliminated.
The study emphasizes that a systematic design
procedure of water resources systems is provided by the
standardized cost- effectiveness approach, which possesses
several advantages. The approach will suggest and help
identify the system closest to meeting the desired economic
and social goals of the developing countries in the Lower
Mekong Basin. In this connection, the approach will help
governments in the preparation of programming and budgeting
of capital for further investigations and investments. It
is believed that the approach will eliminate unnecessary
expenses in projects that are planned on an individual basis
or by methods used at present. Further, the approach provides
an appropriate mechanism for generating essential
information in the decision process. Both quantifiable and
non -quantifiable criteria are fully considered. The choice
of a fixed -cost or fixed -effectiveness approach will determine
the trade -off between these criteria.
The study recognizes that research to determine
appropriate hydrologic models for monthly streamfiow generation for tributary projects in the Basin is necessary.
This leads to another important area of research which is
to find the appropriate number of monthly sequences of
streamflow to be generated in relation to number of states
and decision variables. Research on the design of computer
experiments is necessary to improve simulation as a tool to
estimate the quantitative effects of a given project.
