Book Peakflow Causative Mechanisms and Frequencies at Reynolds Creek  Southwestern Idaho

Download or read book Peakflow Causative Mechanisms and Frequencies at Reynolds Creek Southwestern Idaho written by Tracie Kirkham and published by . This book was released on 2002 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Peakflow frequency analysis is used in forest hydrology for designing stream crossing structures such as culverts and bridges. The traditional approach to frequency analysis is based on the assumption that the observed sample of peakflows represents a homogeneous population. It is not clear if using the "homogeneous" population of the annual series correctly represents the frequency distribution of high flows resulting from different causal mechanisms. This later situation may present a serious problem when extrapolation of the flow frequency curves is required, which is nearly always the case for the estimation of the 50- and 100-year peakflow. The objective of this study was to determine if frequency distributions are different when peakflows are separated by seasonal mechanisms. Additionally, it was desired to compare the peakflow estimates from the traditional annual series results with the separated distributions for a range of exceedence probabilities. Streamfiow data were obtained for three gages at Reynolds Creek Basin, Idaho. For water years 1964 to 1996, the instantaneous maximum flow was identified separately for peakflows that occurred in the winter, prior to snowmelt; in spring, during snowmelt; and in summer, after the snowmelt period. Causative mechanisms were inferred from the seasonal groups and included rain, rain-on-snow, rain on frozen ground in the winter, clear-sky or rain-on-snow in the springtime, and thundershowers in the summer. Separating peakflows resulted in differences between the flow frequency distributions. At the 0.40 km2 headwater basin, Reynolds Mountain East, snowmelt caused the highest flows for exceedence probabilities between the 99% and 1.4%, whereas winter peakflows caused the highest flows for exceedence probabities less than 1.4%. At the 55 km2 basin, Reynolds Creek at Tollgate, snowmelt caused the largest flows for exceedence probabilities between 99% and 7%, and winter mechanisms caused the largest flows for exceedence probabilities less than 7%. At the 239 km2 basin, the Reynolds Creek Outlet, snowmelt caused the greatest flows for exceedence probabilities between 99% and 45%, and winter rainfall, rain-on-snow or rain on frozen soil caused the largest flows for exceedence probabilities equal to or less that 45%. At the Outlet basin, thundershowers caused higher flows than snowmelt mechanisms for exceedence probabilities less than or equal to 4%. The data suggest that stratifying peakflows based on season of occurrence provides a more accurate estimate of the peakflow frequency distributions. The individual curves provide a better idea of the distributions, especially when the curves are extrapolated to low, rarer, exceedence probabilities. Damage to structures may be reduced if causative mechanisms are considered when designing structures using peakflow analysis. Constructing a composite curve to incorporate the probability of each type of seasonal mechanism, in any given year, is an appropriate tool to consider where mixed mechanisms are evident in the streamflow record.

Book Thriving on Our Changing Planet  A Decadal Strategy for Earth Observation from Space

Download or read book Thriving on Our Changing Planet A Decadal Strategy for Earth Observation from Space written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-06-18 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live on a dynamic Earth shaped by both natural processes and the impacts of humans on their environment. It is in our collective interest to observe and understand our planet, and to predict future behavior to the extent possible, in order to effectively manage resources, successfully respond to threats from natural and human-induced environmental change, and capitalize on the opportunities â€" social, economic, security, and more â€" that such knowledge can bring. By continuously monitoring and exploring Earth, developing a deep understanding of its evolving behavior, and characterizing the processes that shape and reshape the environment in which we live, we not only advance knowledge and basic discovery about our planet, but we further develop the foundation upon which benefits to society are built. Thriving on Our Changing Planet: A Decadal Strategy for Earth Observation from Space (National Academies Press, 2018) provides detailed guidance on how relevant federal agencies can ensure that the United States receives the maximum benefit from its investments in Earth observations from space, while operating within realistic cost constraints. This short booklet, designed to be accessible to the general public, provides a summary of the key ideas and recommendations from the full decadal survey report.

Book Urban Stormwater Management in the United States

Download or read book Urban Stormwater Management in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-03-17 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

Download or read book Groundwater written by R. Allan Freeze and published by Prentice Hall. This book was released on 1979 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors preceive a trend in the study and practice of groundwater hydrology. They see a science that is emerging from its geological roots and its early hydraulic applications into a full-fledged environmental science. They see a science that is becoming more interdisciplinary in nature and of greater importance in the affairs of man. This book is their response, and they have provided a text that is suited to the study of groundwater during this period of emergence.
