Download or read book Re envisioning Cross sectional Hydraulic Geometry as Spatially Explicit Hydraulic Topography written by Robert Lee Gonzalez and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Transect-based hydraulic geometry relations are well established, but actually depend on a complex set of opaque fieldwork and computational decisions that sometimes go unexplained. River science is in the midst of a transformation from considering limited cross-sectional data to using an abundance of spatially explicit data. The term `near-census' is used herein to refer to comprehensive, spatially explicit, process-based approaches using the 1-m scale as the basic building block for investigating rivers. Hydraulic geometry is one of the classic tools of fluvial geomorphology that is ripe for re-envisioning from a near-census perspective. This study developed and applied a new spatially explicit method for analyzing discharge-dependent hydraulics coined `hydraulic topography' that not only increases accuracy, but also eliminates several sample- and assumption-based inconsistencies from the traditional method. Hydraulic topography relied on detailed, near-census river surveying and served as the baseline to assess cross-sectional methods. The testbed for comparing hydraulic topography and uniformly spaced cross-sectional hydraulic geometry approaches in this study was a set of meter-scale 2D hydrodynamic simulations of the regulated, gravel-cobble bed lower Yuba River. Using those model results, power functions were fit to discharge-dependent average width, depth, and velocity for three spatial scales and visually inspected. Then their corresponding exponents and coefficients were compared. Average hydraulics values derived from cross sections at the segment scale spanned up to 1.5 orders of magnitude for a given discharge. Transect-determined rates of reach scale depth and velocity increase with changing discharge were consistently over- and underestimated, respectively, relative to the hydraulic topography benchmark. Both methods showed that relative to riffles, pools had lower velocities at low discharges but a higher rate of velocity increase with increased flows. Pool depths were generally under represented by cross-sectional sampling due to inclusion of shallow shoreline depths. Overall, 73 percent of cross-sectional power regression parameters assessed fell between 10 and 50 absolute percent error with respect to the spatially explicit hydraulic topography approach. Although traditional transect-based sampling may be viable for certain uses, percent errors of this magnitude could compromise engineering applications in river management and training works. Using near-census hydraulic topography significantly increases the accuracy and representativeness of the results over cross-section hydraulic geometry.
Download or read book Evaluating River Cross Section Geometry for a Hydraulic River Routing Model written by Alfredo Raul Hijar Santibanez and published by . This book was released on 2015 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new methodology is presented to construct reliable river channel cross section approximations. These approximations are based on the idea of downstream hydraulic geometry as well as supported by the information collected by the USGS streamflow measurement stations across the study area. A hydraulic river routing model (SPRNT) is run with the newly constructed cross section approximations. Initial conditions for the simulation are estimated based on the steady state solution for the model. Boundary conditions or lateral inflows for the river network are estimated based on the outputs of a Land Surface model: Noah, which provides surface and sub-surface runoff for every catchment area in the San Antonio and Guadalupe river basins. Simulations are compared with observed measurements from the USGS stations.

Download or read book River Dynamics written by Bruce L. Rhoads and published by Cambridge University Press. This book was released on 2020-04-29 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rivers are important agents of change that shape the Earth's surface and evolve through time in response to fluctuations in climate and other environmental conditions. They are fundamental in landscape development, and essential for water supply, irrigation, and transportation. This book provides a comprehensive overview of the geomorphological processes that shape rivers and that produce change in the form of rivers. It explores how the dynamics of rivers are being affected by anthropogenic change, including climate change, dam construction, and modification of rivers for flood control and land drainage. It discusses how concern about environmental degradation of rivers has led to the emergence of management strategies to restore and naturalize these systems, and how river management techniques work best when coordinated with the natural dynamics of rivers. This textbook provides an excellent resource for students, researchers, and professionals in fluvial geomorphology, hydrology, river science, and environmental policy.

Download or read book River Mechanics written by Pierre Y. Julien and published by Cambridge University Press. This book was released on 2018-04-12 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of Julien's textbook presents an analysis of rivers from mountain streams to river estuaries. The book is rooted in fundamental principles to promote sound engineering practice. State-of-the-art methods are presented to underline theory and engineering applications. River mechanics blends the dual concepts of water conveyance and sediment transport. Like the first edition, this textbook contains ample details on river equilibrium, river dynamics, bank stabilization, and river engineering. Complementary chapters also cover the physical and mathematical modeling of rivers. As well as being completely updated throughout, three new chapters have been added on watershed dynamics, hillslope stability, and stream restoration. Throughout the text, hundreds of examples, exercises, problems, and case studies assist the reader in learning the essential concepts of river engineering. The textbook is very well illustrated to enhance advanced student learning, while researchers and practitioners will find the book to be an invaluable reference.
