Download or read book Rainfall runoff Modelling In Gauged And Ungauged Catchments written by Thorsten Wagener and published by World Scientific. This book was released on 2004-09-09 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important monograph is based on the results of a study on the identification of conceptual lumped rainfall-runoff models for gauged and ungauged catchments. The task of model identification remains difficult despite decades of research. A detailed problem analysis and an extensive review form the basis for the development of a Matlab® modelling toolkit consisting of two components: a Rainfall-Runoff Modelling Toolbox (RRMT) and a Monte Carlo Analysis Toolbox (MCAT). These are subsequently applied to study the tasks of model identification and evaluation. A novel dynamic identifiability approach has been developed for the gauged catchment case. The theory underlying the application of rainfall-runoff models for predictions in ungauged catchments is studied, problems are highlighted and promising ways to move forward are investigated. Modelling frameworks for both gauged and ungauged cases are developed. This book presents the first extensive treatment of rainfall-runoff model identification in gauged and ungauged catchments.
Download or read book Scale Issues in Hydrological Modelling written by J. D. Kalma and published by John Wiley & Sons. This book was released on 1995-09-11 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing need for appropriate models which address the management of land and water resources and ecosystems at large space and time scales. Theories of non-linear hydrological processes must be extrapolated to large-scale, three-dimensional natural systems such as drainage basins, flood plains and wetlands. This book reports on recent progress in research on scale issues in hydrological modelling. It brings together 27 papers from two special issues of the journal Hydrological Processes. The book makes a significant contribution towards developing research strategies for linking model parameterisations across a range of temporal and spatial scales. The papers selected for this book reflect the tremendous advances which have been made in research into scale issues in hydrological modelling during the last ten years.

Download or read book Statistical Learning for Unimpaired Flow Prediction in Ungauged Basins written by Elaheh White and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: All science is the search for unity in hidden likeness (Bronowski, 1988). There are two practical reasons to approximate processes that produce such hidden likeness: (1) prediction for interpolation or extrapolation to unknown (often future) situations; and (2) inferenceto understand how variables are connected or how change in one affects others. Statistical learning tools aid prediction and at times inference. In recent years, rapidly growing computing power, the advent of machine learning algorithms, and more user-friendly programming languages (e.g., R and Python) support applying statistical learning methods to broader societal problems. This dissertation develops statistical learning models, generally simpler than mechanistic models, to predict unimpaired flows of California basins from available data. Unimpaired flow is the flow produced by the basin in its current state, but without human-created or operated water storage, diversion, or return flows (California Department of Water Resources, Bay-Delta Office, 2016). The models predict unimpaired flows for ungauged basins, an International Association of Hydrological Sciences "grand challenge" in hydrology. In Predicting Ungauged Basins (PUB), the models learn from information at gauged points on a river and extrapolate to ungauged locations. Several issues arise in this prediction problem: (1) How we view hydrology and how we define observational units determine how data is pre-processed for statistical learning methods. So, one issue is in deciding the organization of the data (e.g., aggregate vs. incrementalbasins). Such data transformation or pre-processing is explored in Chapter 2. (2) Often, water resources problems are not concerned with accurately predicting the expectation (or mean) of a distribution but require better estimates of extreme values of the distribution(e.g., floods and droughts). Solving this problem involves defining asymmetric loss functions, which is presented in Chapter 3. (3) Hydrologic observations have inherent dependencies and correlation structure; gauge data are structured in time and space, and rivers form a network of flows that feed into one another (i.e., temporal, spatial, and hierarchical autocorrelation). These characteristics require careful construction of resampling techniques for model error estimation, which is discussed in Chapter 4. (4) Non-stationarity due to climate change may require adjustments to statistical models, especially for long-term decision-making. Chapter 5 compares unimpaired flow predictions from a statistical model that uses climate variables representing future hydrology to projections from climate models. These issues make Predicting Ungauged Basins (PUB) a non-trivial problem for statistical learning methods operating with no a priori knowledge of the system. Compared to physical or semi-physical models, statistical learning models learn from the data itself, withno assumptions on underlying processes. Their advantages lie in their fast and easy development, simplicity of use, lesser data requirements, good performance, and flexibility in model structure and parameter specifications. In the past two decades, more sophisticated statistical learning models have been applied to rainfall-runoff modeling. However, with these methods, there are issues such as the danger of overfitting, their lack of justification outside the range of underlying data sets, complexity in model structure, and limitations from the nature of the algorithms deployed. Keywords: predicting ungauged basins (PUB); rainfall-runoff modeling; asymmetric loss functions; structured data; blocked resampling methods; climate change; water resources; hydrology; statistical learning.

Available in PDF, EPUB and Kindle. Book excerpt: Provides critiques of current practices for environmental flow assessment and shows how they can be improved, using case studies. In Environmental Flow Assessment: Methods and Applications, four leading experts critique methods used to manage flows in regulated streams and rivers to balance environmental (instream) and out-of-stream uses of water. Intended for managers as well as practitioners, the book dissects the shortcomings of commonly used approaches, and offers practical advice for selecting and implementing better ones. The authors argue that methods for environmental flow assessment (EFA) can be defensible as well as practicable only if they squarely address uncertainty, and provide guidance for doing so. Introductory chapters describe the scientific and social reasons that EFA is hard, and provide a brief history. Because management of regulated streams starts with understanding freshwater ecosystems, Environmental Flow Assessment: Methods and Applications includes chapters on flow and organisms in streams. The following chapters assess standard and emerging methods, how they should be tested, and how they should (or should not) be applied. The book concludes with practical recommendations for implementing environmental flow assessment. Describes historical and recent trends in environmental flow assessment Directly addresses practical difficulties with applying a scientifically informed approach in contentious circumstances Serves as an effective introduction to the relevant literature, with many references to articles in related scientific fields Pays close attention to statistical issues such as sampling, estimation of statistical uncertainty, and model selection Includes recommendations for methods and approaches Examines how methods have been tested in the past and shows how they should be tested today and in the future Environmental Flow Assessment: Methods and Applications is an excellent book for biologists and specialists in allied fields such as engineering, ecology, fluvial geomorphology, environmental planning, landscape architecture, along with river managers and decision makers.
Download or read book Explainable AI Interpreting Explaining and Visualizing Deep Learning written by Wojciech Samek and published by Springer Nature. This book was released on 2019-09-10 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of “intelligent” systems that can take decisions and perform autonomously might lead to faster and more consistent decisions. A limiting factor for a broader adoption of AI technology is the inherent risks that come with giving up human control and oversight to “intelligent” machines. For sensitive tasks involving critical infrastructures and affecting human well-being or health, it is crucial to limit the possibility of improper, non-robust and unsafe decisions and actions. Before deploying an AI system, we see a strong need to validate its behavior, and thus establish guarantees that it will continue to perform as expected when deployed in a real-world environment. In pursuit of that objective, ways for humans to verify the agreement between the AI decision structure and their own ground-truth knowledge have been explored. Explainable AI (XAI) has developed as a subfield of AI, focused on exposing complex AI models to humans in a systematic and interpretable manner. The 22 chapters included in this book provide a timely snapshot of algorithms, theory, and applications of interpretable and explainable AI and AI techniques that have been proposed recently reflecting the current discourse in this field and providing directions of future development. The book is organized in six parts: towards AI transparency; methods for interpreting AI systems; explaining the decisions of AI systems; evaluating interpretability and explanations; applications of explainable AI; and software for explainable AI.
