Download or read book Runoff Prediction in Ungauged Basins written by Günter Blöschl and published by Cambridge University Press. This book was released on 2013-04-18 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predicting water runoff in ungauged water catchment areas is vital to practical applications such as the design of drainage infrastructure and flooding defences, runoff forecasting, and for catchment management tasks such as water allocation and climate impact analysis. This full colour book offers an impressive synthesis of decades of international research, forming a holistic approach to catchment hydrology and providing a one-stop resource for hydrologists in both developed and developing countries. Topics include data for runoff regionalisation, the prediction of runoff hydrographs, flow duration curves, flow paths and residence times, annual and seasonal runoff, and floods. Illustrated with many case studies and including a final chapter on recommendations for researchers and practitioners, this book is written by expert authors involved in the prestigious IAHS PUB initiative. It is a key resource for academic researchers and professionals in the fields of hydrology, hydrogeology, ecology, geography, soil science, and environmental and civil engineering.

Download or read book Streamflow Characteristics written by H.C. Riggs and published by Elsevier. This book was released on 1985-01-01 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reliable estimates of streamflow characteristics are needed for planning, design, and operation of works for providing water supplies and for protection from flooding. This book brings together some of the most useful estimation methods - those that are simple, practical, and require only commonly available or readily obtainable data, and which give results comparable in accuracy with those derived from more sophisticated methods. The author describes how streamflow data are collected, how the characteristics are computed, how they are changed by man's activities, and how they are used in planning and design. Chapters describing statistical principles and techniques, and the effects of various climatic and physiographic factors on streamflow are included. The analytical methods are described in sufficient detail that the reader can apply them to his data. Further applications and other techniques are referred to in bibliographies.

Download or read book Flow Duration Curve Prediction for Ungauged Basins written by and published by . This book was released on 2016 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flow duration curve (FDC) is one of the most widely used tools for displaying streamflow data, and percentile flows derived from the FDC provide essential information for managing rivers. These statistics are generally not available since most basins are ungauged. Percentile flows are frequently predicted using regression models developed using streamflow and ancillary data from gauged basins. Many potential independent variables are now available to predict percentile flows due to the ready availability of spatially distributed physical and climatic data for basins. A subset of the variables is often selected using automated regression procedures, but these procedures only evaluate a portion of the possible variable combinations. Other approaches for exploiting the information from physical and climatic data may produce stronger models for predicting percentile flows. The overarching hypothesis guiding this dissertation research was that more extensive approaches for extracting information from large sets of independent variables may improve percentile flow predictions. The dissertation was organized into the following three linked studies: (1) a performance evaluation of various approaches for selecting the independent variables of percentile flow regression models, (2) a comparison of different sets of variables for percentile flow regression modeling with increasing amounts of information in terms of the number of variables and their description of the statistical distribution of the data, and (3) a proof-of-concept study using a neural network approach called the self-organizing map (SOM) to account for the noise and non-linearity of predictive relations between the independent variables and percentile flows. Key findings from these studies were as follows: (1) random forests was the best approach for selecting the independent variables for regression models used to predict percentile flows, but variables selected based on a conceptual understanding of the FDC performed nearly as well, (2) a set of only three variables (mean annual precipitation, potential evapotranspiration, and baseflow index) performed as well as models with larger sets of variables representing more physical and climatic information, and (3) the SOM performed similarly to global regression models based on all the basins, but did not outperform regression models developed for regions composed of similar basins. This may be due to the SOM using all the independent variables, whereas the regression models discarded irrelevant variables that could increase the error in percentile flow predictions. All the studies of this dissertation were performed using 918 basins in the contiguous US, and the resulting predictive models provide a tool for local watershed managers to predict 13 percentile flows along with an estimate of the predictive error. These models could be improved through future research that (1) emphasizes the role of geology as this provided the most valuable information for predicting the percentile flows, (2) exploits new sources of remotely sensed information as classic topographic variables provided little predictive information, and (3) develops specialized models designed for high and low flows as these were the most difficult to predict.
