River Dynamics 101 - Fact Sheet River Management Program Vermont Agency of Natural Resources
River Dynamics 101 - Fact Sheet River Management Program Vermont Agency of Natural Resources Overview In the discussion of river, or fluvial systems, and the strategies that may be used in the management of fluvial systems, it is important to have a basic understanding of the fundamental principals of how river systems work. This fact sheet will illustrate how sediment moves in the river, and the general response of the fluvial system when changes are imposed on or occur in the watershed, river channel, and the sediment supply. The Working River The complex river network that is an integral component of Vermont’s landscape is created as water flows from higher to lower elevations. There is an inherent supply of potential energy in the river systems created by the change in elevation between the beginning and ending points of the river or within any discrete stream reach. This potential energy is expressed in a variety of ways as the river moves through and shapes the landscape, developing a complex fluvial network, with a variety of channel and valley forms and associated aquatic and riparian habitats. Excess energy is dissipated in many ways: contact with vegetation along the banks, in turbulence at steps and riffles in the river profiles, in erosion at meander bends, in irregularities, or roughness of the channel bed and banks, and in sediment, ice and debris transport (Kondolf, 2002). Sediment Production, Transport, and Storage in the Working River Sediment production is influenced by many factors, including soil type, vegetation type and coverage, land use, climate, and weathering/erosion rates. -

Chapter 11 – Glossary of Terms
CHAPTER 11 GLOSSARY OF TERMS WORD DEFINITION SOURCE Active Channel The channel that contains the discharge Leopold where channel maintenance is most effective, sediment are actively transported and deposited, and that are capable of containing most flows. Active channels are located within the area bounded by bankfull stages. Active Flood plain Low lying areas built by watercourse Collaborative, sediment depositions between top of bank Leopold that are adjacent to a watercourse and that have been constructed by the present river in the present climate. These areas are susceptible to frequent inundation during moderate and higher flows when the active channel’s capacity is exceeded. Active floodplains are most prominent along low- gradient, meandering reaches and are often absent or undistinguishable along steeper sloped stream channels.

Technical Note #9 is subdivided into the following Sections: Section 9.1 Ecological Definitions Section 9.2 A Technical Glossary of Stream & River Stabilization, Restoration, and Bioengineering Terms Section 9.3 Glossary of Terminology commonly used in Mining & Reclamation Technology SECTION 9.1 Ecological Definitions (S.M. Lambert, 1994; revised/updated M.E. Stannard, 2005) ECOSYSTEM A biological community together with the physical, social and chemical environment with which it interacts. ECOREGIONS Regions that have broad ecological similarities with respect to soil, relief, and dominant vegetation. Ecoregions are less commonly used by NRCS in its day-to-day terminology. NRCS uses Major Land Resource Areas and Conservation Resource Areas. MAJOR LAND RESOURCE AREAS (MLRA) Geographically associated land resource units, usually encompassing several thousand acres. They are characterized by particular patterns of soils, geology, climate, water resources, and land use. A unit may be one continuous area or several separate nearby areas. CONSERVATION RESOURCE AREAS (CRA) A geographical area where resource concerns, problems, or treatment needs are similar. It is considered a subdivision of an existing Major Land Resource Area (MLRA) map delineation or polygon. Landscape conditions, soil, climate, human considerations, and other natural resource information are used to determine the geographic boundaries of a Common Resource Area.

Water Life: Riffles and Pools Stream Ecosystems Provide a Habitat Or
Water Life: Riffles and Pools Stream ecosystems provide a habitat or natural environment for many diverse aquatic organisms and plants. A deeper look indicates each stream has a distinctive anatomy as each is composed of a series of pools, riffles and runs. Pools: An area of the stream characterized by deep depths and slow current. Pools are typically created by the vertical force of water falling down over logs or boulders. The movement of the water carves a deeper indentation in the stream bed. Pools are important because they can provide depth and still water. Riffles: An area of stream characterized by shallow depths with fast, turbulent water. The riffles are short segments of the stream where water flow is agitated by rocks. The rocky Adapted from: bottom provides protection from predators, food http://share3.esd105.wednet.edu/rsandelin/ees/Resources/Flowing%20water%20concepts.htm deposition and shelter. Riffle depths vary depending upon stream size, but can be as shallow as 1 inch or deep as 1 meter. The turbulence and stream flow results in high dissolved oxygen concentration. Run: An area of stream characterized by moderate current, continuous surface and depths greater than riffles. Runs are stretches of the stream downstream of pools and riffles where stream flow and current are moderate. The smooth surface allows for light to penetrate. Microhabitats: Habitats are the natural environment in which an organism lives. The distinguishing abiotic conditions of riffles, pools and runs result in specialized environments that are known as microhabitats. The abiotic conditions (dissolved oxygen, turbidity, light and temperature) of these microhabitats can influence which aquatic species can survive and reproduce at that given location and time. -
