Overview of Watershed and Channel Sedimentation
This lesson provides an overview of the primary influences of watershed and channel sedimentation. In a short narrated portion of the lesson, we explore a section of the Rio Grande watershed and channel in New Mexico using Google Earth imagery, river profiles, and graphic animations. We highlight features of the upland catchments, the river channel, and the Elephant Butte Reservoir. We then demonstrate how environmental factors (climate, geography, land use changes, reservoirs) impact the supply and movement of sediments for the Rio Grande and other rivers. The focus is on the three primary pr ...
Flood Risk Management: A Strategic Approach
ADB, 2013Over recent decades the concept of flood risk management has been cultivated across the globe. Implementation however remains stubbornly difficult to achieve. In part this reflects the perception that a risk management paradigm is more complex than a more traditional standard-based approach as it involves "whole systems" and "whole life" thinking; yet this is its main strength and a prerequisite for more integrated and informed decision making.
This book is the result of a collaborative effort between the World Wide Fund for Nature (WWF), the General Institute of Water Resources ...

Integrated flood management tools series, 16. Management of Flash Floods
World Meteorological Organization (WMO) ; Associated Programme on Flood Management (APFM); Global Water Partnership (GWP) - WMO, 2012This tool provides an overview of approaches and practical actions to reduce disaster risks associated with flash floods. Flood forecasting and warning are expected to play an important role in flash flood management though there are scientific and technical limits to provide accurate and timely warnings. Spatial planning and flood proofing can also reduce risk of exposure. These require flood hazard mapping to assess the risk of flash floods and an appropriate legal framework to integrate (flash) flood management planning and spatial planning. Participatory approach can identify areas at risk ...

Weaving a culture of resilience, a gender-sensitive approach to disaster risk reduction in Vanuatu and the Solomon Islands
This document reports on a research aiming at a more gender-sensitive approach to disaster risk reduction (DRR) in Vanuatu and the Solomon Islands. It gives insight on the situations in which women and men, girls and boys live in three selected communities in both countries. It provides information about their local behaviour patterns, belief and value systems, their daily life routines etc. - all necessary information to adapt ongoing and plan future DRR measures in this specific context.
Flash Flood Processes: International Edition
Flash floods can occur in nearly any area of the world. A rainfall-induced flash flood is a truly hydrometeorological event: one that depends on both hydrologic and meteorological conditions. Forecasting flash floods involves a detailed understanding of the local hydrologic features and continual monitoring of the current meteorological situation. This module examines both the hydrologic and meteorological processes that often contribute to the development of flash flooding. Common tools and technologies that are used in flash flood monitoring and forecasting, from manual gauging systems to co ...
Flood Forecasting Case Study: International Edition
This module allows users to explore the flood forecasting process by assuming the role of a visiting hydrologist intern at the National Hydrologic Service in Main Country. Fictional senior hydrologists guide the intern through an idealized flooding event that takes place over Main Country's Mainstem river basin and its tributary basins, each with varying landscapes and observation systems. Users will examine how these variations impact the quality and type of forecast that can be achieved. Users will also learn about common problems encountered in flood forecasting, and how to adjust forecasts ...
Flash Flood Early Warning System Reference Guide
The Flash Flood Warning System Reference Guide is intended to promote the implementation of flash flood early warning systems based upon proven and effective methods already in use in flash-flood prone nations around the world. Both governmental and non-governmental decision makers can use it to better understand flash floods and the elements that constitute a robust, end-to-end flash flood early warning system. The guide includes chapters on Flash Flood Science, Flash Flood Forecasting Methods, Monitoring Networks, Technology Infrastructure, Warning Dissemination and Notification, and Communi ...
Distributed Hydrologic Models for Flow Forecasts - Part 2
Distributed Hydrologic Models for Flow Forecasts Part 2 is the second release in a two-part series focused on the science of distributed models and their applicability to different flow forecasting situations. Presented by Dr. Dennis Johnson, the module provides a more detailed look at the processes and mechanisms involved in distributed hydrologic models. It examines the rainfall/runoff component, snowmelt, overland flow routing, and channel response in a basin as represented in a distributed model. Calibration issues and situations in which distributed hydrologic models might be most appropr ...
QPF Verification: Challenges and Tools
This module looks at the common challenges and tools with respect to verification of quantitative precipitation forecasts (QPF). Through the use of rich illustrations, animations, and interactions, this module provides an introduction to a variety of methods and approaches for assessing the quality of QPFs. The module examines the need for, and the challenges of verifying precipitation forecasts. An overview is then presented of three verification programs available to most NWS forecast offices: the Hydrometeorological Prediction Center (HPC) verification, the National Precipitation Verificati ...
River Ice Processes - Short Version
This module provides information on flooding associated with river ice jams. Based on a presentation by Dr. Kate White, a nationally-recognized expert on river ice, this webcast explores basic river ice processes including the formation, growth, breakup, and transport of river ice and how it can become jammed, triggering floods. This shorter version of the previously published module "River Ice Processes", has less focus on the US National Weather Service, making it more broadly applicable, including to an international audience.
Distributed Hydrologic Models for Flow Forecasts - Part 1
Distributed Hydrologic Models for Flow Forecasts – Part 1 provides a basic description of distributed hydrologic models and how they work. This module is the first in a two-part series focused on the science of distributed models and their applicability in different situations. Presented by Dr. Dennis Johnson, the module begins with a review of hydrologic models, and then examines the differences between lumped and distributed models. It explains how lumped models may be distributed by subdividing the basin and suggests when distributed hydrologic models are most appropriate. Other topics cove ...

As a foundation topic for the Basic Hydrologic Science course, this module may be taken o ...
Flash Flood Processes
According to NOAA’s National Weather Service, a flash flood is a life-threatening flood that begins within 6 hours--and often within 3 hours--of a causative event. That causative event can be intense rainfall, the failure of a dam, levee, or other structure that is impounding water, or the sudden rise of water level associated with river ice jams. The “Flash Flood Processes” module offers an introduction to the distinguishing features of flash floods, the underlying hydrologic influences and the use of flash flood guidance (FFG) products. Through use of rich illustrations, animations, and inte ...
