Book Synopsis Riverbank Filtration Hydrology by : Stephen A. Hubbs
Download or read book Riverbank Filtration Hydrology written by Stephen A. Hubbs and published by Springer Science & Business Media. This book was released on 2007-11-04 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Riverbank Filtration (RBF) has gained popularity in the past decade as an excellent source of high quality water for public water supply. This text compliments the existing literature on RBF water quality, and provides much-need guidance in the design and operation of RBF facilities. RBF has proven effective in many hydrogeological settings worldwide, and can be an excellent solution to water supply problems in both developed and developing countries. Topics covered include surface stream hydrology, particle clogging, and biological/geochemical processes. Data and case histories are provided from dozens of installations, providing much-needed practical information regarding RBF design, operation, and performance. This book provides the necessary tools to evaluate potential RBF sites, and is a must-have if you are considering RBF as a source of water supply.

Book Synopsis Use of a Two-dimensional Flow Model to Quantify Aquatic Habitat by : D. Michael Gee
Download or read book Use of a Two-dimensional Flow Model to Quantify Aquatic Habitat written by D. Michael Gee and published by . This book was released on 1985 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes the impacts of potential hydropower retrofits on downstream flow distributions at Lock and Dam No. 8 on the upper Mississippi River. The model used solves the complete Reynolds equations for two-dimensional free-surface flow in the horizontal plane using a finite element solution scheme. RMA-2 has been in continuing use and development at the Hydrologic Engineering Center and elsewhere for the past decade. Although designed primarily for the simulation of hydraulic conditions, RMA-2 may be used in conjunction with related numerical models to simulate sediment transport and water quality. In this study, velocity distributions were evaluated with regard to environmental, navigational and small-boat safety considerations. Aquatic habitat was defined by depth, substrate type and current velocity. Habitat types were quantified by measuring the areas between calculated contours of velocity magnitude (isotachs) for existing and project conditions. The capability for computing and displaying isotachs for the depth-average velocity, velocity one foot from the bottom and near the water surface was developed for this study. The product of this study effort is an application of the RMA-2 model that allows prediction of structural aquatic habitat in hydraulicaly complex locations. Elements of the instream flow group methodology could be incorporated to provide detailed predictions of impacts to habitat quality. Calibration of the numerical model to field measurements of velocity magnitude and direction is also described.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two-dimensional (depth-averaged) hydrodynamic models have existed for decades and are used to study hydrogeomorphic processes, evaluate stage-dependent physical habitat patterns, and design river-rehabilitation projects. Rapid computer and coding advances are revolutionizing the size and detail of 2D models. Meanwhile, advances in topographic mapping and environmental informatics are providing the data inputs to drive large, detailed simulations. Million-element computational meshes are readily operational. With simulations of this size and detail, the primary challenge has shifted to finding rapid and inexpensive means for testing model predictions against observations. Standard methods for collecting velocity data include boat-mounted ADCP and point-based sensors on boats or wading rods. These methods are labor intensive and often limited to a narrow flow range. Also, they generate small datasets at a few cross-sections, which is inadequate to characterize the statistical structure of the relation between predictions and observations. Drawing on the long-standing oceanographic method of using drogues to track water currents, previous studies have demonstrated the potential of small dGPS units to obtain surface velocity in rivers. However, dGPS is too inaccurate to test 2D models. Also, there is financial risk in losing drogues in rough currents. In this study, a real time kinematic (RTK) GPS unit was mounted onto a manned whitewater kayak. The boater positioned himself into the current and used floating debris to maintain a speed and heading consistent with the ambient surface flow field. RTK GPS measurements were taken every 5 seconds. From these positions, near-surface 2D velocity vectors were obtained. The method was tested over ~7.2 km of the lower Yuba River in California in flows ranging from ~15-140 m3/s, yielding 5816 observations. To compare surface velocity magnitude against the 2D model-predicted depth-averaged value, kayak-based surface values were scaled down by a published value and three optimized constants, which had no negative effect on regression analysis. The R2 value for speed was 0.79 by this method, compared with 0.57 based on 199 points from traditional point measurements. The R2 value for velocity direction was 0.80. Although it is not ideal to rely on observed surface velocity to evaluate depth-average velocity predictions, all available velocity-measurement methods have a suite of assumptions and complications. Using this method, the availability of 10-100x more data was so beneficial that the outcome was among the highest 2D-model performance outcomes reported in the available literature.
