Download or read book Improving Flood Prediction Assimilating Uncertain Crowdsourced Data into Hydrologic and Hydraulic Models written by Maurizio Mazzoleni and published by CRC Press. This book was released on 2017-03-16 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the continued technological advances have led to the spread of low-cost sensors and devices supporting crowdsourcing as a way to obtain observations of hydrological variables in a more distributed way than the classic static physical sensors. The main advantage of using these type of sensors is that they can be used not only by technicians but also by regular citizens. However, due to their relatively low reliability and varying accuracy in time and space, crowdsourced observations have not been widely integrated in hydrological and/or hydraulic models for flood forecasting applications. Instead, they have generally been used to validate model results against observations, in post-event analyses. This research aims to investigate the benefits of assimilating the crowdsourced observations, coming from a distributed network of heterogeneous physical and social (static and dynamic) sensors, within hydrological and hydraulic models, in order to improve flood forecasting. The results of this study demonstrate that crowdsourced observations can significantly improve flood prediction if properly integrated in hydrological and hydraulic models. This study provides technological support to citizen observatories of water, in which citizens not only can play an active role in information capturing, evaluation and communication, leading to improved model forecasts and better flood management.

Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive series of interconnected computer models are described which assist water control managers in operating reservoir systems during real-time flood emergencies. The need for and the desirable features of a transportable comprehensive software system are presented along with a description of the various computer models developed for this purpose by the Hydrologic Engineering Center of the U.S. Army Corps of Engineers. The functions, capabilities and inerties of the Data Management, Operation, Forecast and Display computer modules used in this software system are described and an example application of this system on one of the Corps' reservoir systems is presented.

This book was released on 1980 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer program HEC-1, a precipitation-runoff model widely used throughout the United States, includes the capability to estimate automatically any of twelve parameters necessary to model the precipitation-runoff process and the channel routing process. The parameter estimation scheme employs Newton's method to minimize a weighted sum of squares of differences between observed and computed hydrograph values. Applications of this parameter estimation procedure are presneted, and typical steps of the procedure for deterimining optimal parameter estimates are outlined. Recent efforts to improve the estimation algorithm and recent use of the calibration capability to update sequentially parameter estimates in a flood forecasting application are discussed. (Author).
Download or read book Water and Related Land Resource Systems written by Y. Haimes and published by Elsevier. This book was released on 2014-05-23 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water and Related Land Resource Systems covers IFAC Symposium that aims to address resource problem, as well as methodologies and procedures for respective solutions. Consists of 60 chapters, the book is organized in sessions according to the technical program of the conference. The book first tackles multiobjective planning in water and land resources, which is followed by acquisition and analysis of surface water quality data. The next part covers hierarchical water resource planning and management models, while the succeeding part is about environmental and ecological aspects of water and land resources. The fifth session discusses the impact of energy development on water and land resources. Session VI covers modeling and systems identification problems in water resources, and Session VII covers acquisition and analysis of hydrologic data. The eighth session tackles ground water and its conjunctive use with surface water, while the next session talks about sedimentation and land management. The tenth session is about multiobjective planning in water and land resources. Predicting and forecasting models in water resources is the topic of Session XI, while Session XII discusses evaluation and calibration problem in water resource modeling. The closing chapter covers water and land issues in urban areas. Professionals whose work revolves around recourse management and researchers whose work is in line with natural resource will find great information in this book that will be relevant in their trade.
