A unit hydrograph shows the temporal change in flow, or discharge, per excess unit of precipitation runoff. This module offers a thorough introduction to the use of unit hydrographs and the application of unit hydrograph theory in flood prediction.

  • Topics:
    Hydrology/Flooding
    (168 ratings)
  • Description

  • Streamflow routing provides a set of methods for describing and predicting the movement of water from one point to another along a river. Typically, this process involves predicting the shape of a hydrograph downstream from a particular location in a channel, reservoir, or lake. This first requires an understanding of the basic flow regimes and how water is stored and released within a channel. From there, information and calculations based on flow and channel bed characteristics are implemented in hydrologic routing methods, which are storage-based, and hydraulic routing methods, which utilize fully-dynamic equations. This module offers a thorough introduction to these routing concepts and processes through illustrations, animations and sample exercises, with a primary focus on hydrologic routing methods.

  • Description

  • 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 complex radar- and satellite-based runoff models, are explored. This module also examines the strengths and limitations of these technologies, as well as how they are likely to advance in the future.

  • Description

  • 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 accordingly. This module is intended for a diverse audience that uses a variety of observing and computing technologies, and builds upon material covered in the foundation topics of the International Basic Hydrologic Sciences Course. These core foundation topics are recommended as a prerequisite since this module assumes some pre-existing knowledge of hydrologic principles.
