The subject of rainfall-runoff modeling involves a wide spectrum of topics. Fundamental to each topic is the problem of accurately computing runoff at a point given rainfall data at another point. The fact that there is currently no one universally accepted approach to computing runoff, given rainfall data, indicates that a purely deter ministic solution to the problem has not yet been found. The technology employed in the modern rainfall-runoff models has evolved substantially over the last two decades, with computer models becoming increasingly more complex in their detail of describing the hydrologic and hydraulic processes which occur in the catchment. But despite the advances in including this additional detail, the level of error in runoff estimates (given rainfall) does not seem to be significantly changed with increasing model complexity; in fact it is not uncommon for the model's level of accuracy to deteriorate with increasing complexity. In a latter section of this chapter, a literature review of the state-of-the-art in rainfall-runoff modeling is compiled which includes many of the concerns noted by rainfall-runoff modelers. The review indicates that there is still no deterministic solution to the rainfall-runoff modeling problem, and that the error in runoff estimates produced from rainfall-runoff models is of such magnitude that they should not be simply ignored.
Rainfall: Physical Process, Measurement, Data Analysis and Usage in Hydrological Investigations integrates different rainfall perspectives, from droplet formation and modeling developments to the experimental measurements and their analysis, to application in surface and subsurface hydrological investigations. Each chapter provides an updated representation of the involved subject with relative open problems and includes a case study at the end of the chapter. The book targets postgraduate readers studying meteorology, civil and environmental engineering, geophysics, agronomy and natural science, as well as practitioners working in the fields of hydrology, hydrogeology, agronomy and water resource management. Presents comprehensive coverage of rainfall-related topics, from the basic processes involved in the drop formation to data use and modeling Provides real-life examples for practical use in the form of a case study in each chapter
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 191. Rainfall: State of the Science offers the most up-to-date knowledge on the fundamental and practical aspects of rainfall. Each chapter, self-contained and written by prominent scientists in their respective fields, provides three forms of information: fundamental principles, detailed overview of current knowledge and description of existing methods, and emerging techniques and future research directions. The book discusses Rainfall microphysics: raindrop morphodynamics, interactions, size distribution, and evolution Rainfall measurement and estimation: ground-based direct measurement (disdrometer and rain gauge), weather radar rainfall estimation, polarimetric radar rainfall estimation, and satellite rainfall estimation Statistical analyses: intensity-duration-frequency curves, frequency analysis of extreme events, spatial analyses, simulation and disaggregation, ensemble approach for radar rainfall uncertainty, and uncertainty analysis of satellite rainfall products The book is tailored to be an indispensable reference for researchers, practitioners, and graduate students who study any aspect of rainfall or utilize rainfall information in various science and engineering disciplines.
This book describes aspects of rainfall including the extremes, distribution and properties. The introductory chapter focusses on drought and flooding rains over Australia, placing extreme rainfall events from recent decades into a historical context using reconstructions from proxy data. The next three chapters focus on distribution and impacts of rainfall. The first of these chapters presents a statistical analysis of rainfall patterns for Jeddah City and considers future impacts. The second examines rainfall in the context of impacts, vulnerability and climate change in eastern Africa. The third examines extreme rainfall and drought in the Asia-Pacific, through application of monitoring from space. The final chapters focus on properties of rain, one examining aerosol-cloud-precipitation interactions, while another considers the chemical nature of individual size-resolved raindrops.
This collection contains seven peer-reviewed papers on engineering design for precipitation extremes presented at the ASCE Workshop on Engineering Methods for Precipitation under a Changing Climate, held in Reston, Virginia, May 30, 2017.
This edited book covers all aspects of River related disasters, challenges, and opportunities. Step-by-step descriptions are provided of river dynamics and associated hazards, and their applications in hazard assessments, accompanied by several experimental, filed and numerical studies. In addition, a systematic table of content is given to aid in identifying River hazards challenges and opportunities. Essential information is provided on River dynamics, hydrological processes and climate change issues, and an individual chapter is devoted to ecological restoration and river hazard management. Further topics include the stability of hydraulic structures, sediment transport, and debris flow in the hilly streams. This book will provide students, researchers, scientists, water resources managers with a comprehensive overview of the River dynamics and flood hazards in various sectors of water-related disasters and will enable them to explore the scope of application of the computational techniques and will enable them to explore the scope of River related disasters, allied branches and their field-specific problems. Professionals and policymakers may also explore the implementation of these approaches in their workplace to tackle complex river dynamics and hydrological phenomena occurring in their study area.
