Third-year and postgraduate courses in physical geography, environmental studies and environmental science, particularly course units in geomorphology, climatology, pedology, biogeography, ecology; landscape ecology, GIS and remote sensing, and environmental modelling. This is the first book of its kind, focusing on topographic influences on environmental components. As a comprehensive introduction to the subject, Topography and the environment discusses the main facets of topography, including new and old ideas, models, methods, and theories, and identifies four different approaches to topography as an environmental factor: the physical ground surface; all the features of the Earth's surface, including the human-made; topographically based modelling, developed in association with geographical information systems (GIS); and the idea of place as a human construct. The authors then explore individual topographic influences on environmental elements such as climate, water, soils and plants. Accessible and wide ranging, it helps students understand the intrinsic links and the crossdisciplinary nature of physical systems and processes.

Latest developments of urban hydrology and hydraulic design procedures for storm water management.Drainage planning is an approach that integrates both local and regional efforts to identify drainage conveyance and storage facilities based on hydrologic optimization and cost minimization individually and collectively. In general, the first six chapters cover the hydrologic procedures for rainfall and runoff predictions, and the next 12 chapters focus on hydraulic designs of urban channel, culvert, street inlet, sewer drain, detention basin, retention basin, infiltration basin, low impact designs, and storm water modeling techniques by various routing methods.Hydrology analyses are lengthy in calculation and repetitive in procedure. As a result, Excel Spreadsheet is the most useful and handy tool for hydraulic and hydrologic designs. This book includes 18 sets of spreadsheets developed for 18 subjects. With these spreadsheets, it is easy for the reader to conduct sensitivity tests. Many of the design methods documented in this book have been adopted as the recommended design procedure by Denver, Las Vegas, and Sacramento metropolitan areas in the United States. Based on these methods, there are many design computer models that have been developed and supported by the Denver metro governments for stormwater design purposes.

This broad review of the development of US water resource policy analysis and practice offers perspectives from several disciplines: law, economics, engineering, ecology and political science. While the historical context provided goes back to the early 19th century, the book concentrates on the past 60 years and features a discussion of the difficulty that has generally been encountered in bringing the disciplines of economics and ecology into collaboration in the water resource context. The book explores the evolution of water related analytical capabilities and institutions and provides illustrations from case studies, concluding with recommendations for research, institutional change and action. Though designed to be a background textbook for interdisciplinary graduate seminars in water resources planning and management, it is accessible to interested lay readers and those who have policymaking or implementation responsibility but lack a technical background. The book will appeal to students and faculty in water policy, economics, and engineering, and in interdisciplinary programs organized around water resource problems and questions. Policy makers and general readers will also appreciate this non-technical introduction.

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.

Floods cause distress and damage wherever and whenever they happen. Flooding from rivers, estuaries and the sea threatens many millions of people worldwide and economic and insurance losses from flooding have increased significantly since 1990. Across the European Union, flood management policy is changing in response to the EU Directive on the assessment and management of flood risks, which requires a move from flood protection and defence to comprehensive flood risk management. Flood Risk Management: Research and Practice includes about 200 contributions from the international conference FLOODrisk 2008 (Oxford, UK, 30 September – 2 October 2008). FLOODrisk 2008 was an initiative of the FLOODsite research project on Integrated Flood Risk Analysis and Management Methodologies. FLOODsite was a major “Integrated Project” in the European Commission Sixth Framework Programme; contract number GOCE-CT-2004-505420. The conference provided a forum for leading researchers, flood risk managers, policy makers and practitioners from government, commercial and research organisations to gain an overview of advances in this important subject. Flood risk management practice crosses several professions and disciplines and these are represented in the breadth of the scope of the conference and these proceedings. The conference covered all aspects of flood risk: the causes of floods, their impacts on people, property and the environment, and portfolios of risk management measuresm, while the principal themes included: climate change, estimation of extremes, flash floods, flood forecasting and warning, inundation modelling, systems analysis, uncertainty, international programmes, flood defence infrastructure and assets, environmental impacts, human and social impacts, vulnerability and resilience, risk sharing, equity and social justice, and, civil contingency planning and emergency management. Flood Risk Management: Research and Practice will be of interest to an international readership, ranging from authorities, consultants and engineers involved in flood management; researchers, post graduate lecturers and students, to policy makers, particularly at national level.

Arid and semi-arid regions are defined as areas where water is at its most scarce. The hydrological regime in these areas is extreme and highly variable, and they face great pressures to deliver and manage freshwater resources. However, there is no guidance on the decision support tools that are needed to underpin flood and water resource management in arid areas. UNESCO initiated the Global network for Water and Development Information for arid lands (GWADI), and arranged a workshop of the world's leading experts to discuss these issues. This book presents chapters from contributors to the workshop, and includes case studies from the world's major arid regions to demonstrate model applications, and web links to tutorials and state of the art modelling software. This volume is a valuable reference for researchers and engineers working on the water resources of arid and semi-arid regions.

Since climate and land use strongly affect the runoff pattern and intensity of solute export, it is likely that some observations and conclusions formulated on the basis of investigations carried out in forested catchment may not be fully adequate to describe controls on solute export from agricultural watersheds. The primary objective of the present research is to better understand the flow paths that affect the fluxes of dissolved compounds from a small agricultural catchment during snowmelt. This book focuses on spring snowmelt, because this is the dominant hydrological event in many moderate and high latitude catchments and, thus, is regarded as a prominent factor influencing the quality of surface waters
