Book Flood Evaluation and Dam Safety

Download or read book Flood Evaluation and Dam Safety written by CIGB ICOLD and published by CRC Press. This book was released on 2018-08-06 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrology and dams are two fields that are obviously closely related. Four bulletins have so far been published by the Committee: Selection of Design Flood – Current methods, Dams and Floods – Guidelines and cases histories, Role of Dams in Flood Mitigation – A review and Integrated Flood Management. These bulletins have essentially addressed floods, the risks they represent and their significance for the concerned populations. The present Bulletin deviates slightly from this path, adopting a somewhat more technical perspective. The text consists of three chapters, conceived to be accessible to the practitioners.

Book GIS Static Storm Model Development

Download or read book GIS Static Storm Model Development written by Francisco Olivera and published by . This book was released on 2004 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rainfall runoff modeling at a watershed scale requires the definition of the storm event and of the conveying characteristics of the watershed. This research project focuses on the geographic definition of the storm event, that is, on the spatial distribution of precipitation over the watershed. As the watershed size increases, the likelihood that a storm will cover the entire watershed decreases, and it becomes necessary to identify which parts of the watershed are affected by the storm and which are not. Traditionally, precipitation estimates have been based on precipitation records obtained at discrete points (i.e., precipitation stations), which led to depth-duration-frequency (DDF) equations or curves. An estimate of the area covered by the storm event, however, has not been included in the analysis, and it has been customary to assume it uniformly distributed over the entire watershed, regardless of its size. Thus far, no model has been developed to map the area of the watershed that is covered by the storm, as well as to determine the spatial distribution of precipitation over this area. Use of NEXRAD precipitation data, however, will allow the development of a model and geographic-information-systems (GIS) based application that relaxes the assumption of uniformly distributed precipitation and estimates the storm precipitation distribution within the watershed.

Book Transformation of Point Rainfall to Areal Rainfall by Estimating Areal Reduction Factors Using Radar Data for Texas

Download or read book Transformation of Point Rainfall to Areal Rainfall by Estimating Areal Reduction Factors Using Radar Data for Texas written by Tarun Deep Gill and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Information about extreme precipitation is of great interest for a variety of purposes, which include dam design and its operation, public safety, engineering projects concerned with river management and drainage as well as rainfall-runoff relations. These require knowledge about the spatial and temporal variability of average rainfall over an area. Design rainfall values are generally expressed in the form of point rainfall intensity values which is the rainfall depth at a location. In order to obtain areal average values for an area, hydrologists and engineers require techniques whereby point rainfall amounts can be transformed to average rainfall amounts over a specified area. This problem of point-to-area rainfall conversion can be addressed using depth-area curves which require the use of areal reduction factors. The derivation of areal reduction factors is a focal issue and has been dealt with in diverse manners. Though the methods of derivation of the areal reduction factors vary, results shown by them are comparable. But all these methods have certain shortcomings in the procedures adopted by them. In this application the analysis is based on radar rainfall values obtained from NEXRAD for the study area of Texas as provided by West Gulf River Forecasting Centre (WGRFC). Using NEXRAD radar rainfall data, geographically fixed depth area relationships will be determined. Here the objectives are to develop areal reduction factors using radar data and to identify the potential obstacles that might hinder the use of such data. The values of the factors developed will be finally compared to other studies which have been carried out. This approach aims to mitigate the difficulties faced in the applications of various procedures and the shortcomings of the various techniques used to determine the values of areal reduction factors.

Book Water resources Engineering

Book excerpt: "Water-Resources Engineering, by David A. Chin, provides students with a complete picture of water-resources engineering by integrating the fundamental concepts of fluid mechanics, hydraulics, hydrology, and containment transport processes. The material in the text is presented from first principles, is rigorous, is relevant to the practice of water-resources engineering, and is reinforced by detailed presentations of design applications."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
