The Meta River is one of the principal branches of the Orinoco River, and it has a high environmental and economic value for this South American country. -
Stream Discharge (Streamflow)
The Importance of Streamflow in California’s Southern Sierra Nevada Mountains Kings River Experimental Watersheds Because 55 to 65 percent of California’s developed water comes from small streams in the Sierra Nevada, it is important to under- stand the role the snowpack has in the distribution and quantity of stream discharge (streamflow). In the southern Sierra, more than 80 percent of precipitation falls December through April. However, owing to the delay in snowmelt, there is a lag in runoff until the spring. At higher elevation sites, the spring melt does not peak until May or even June. This makes mountain water available to California during the summer months. The Kings River Experi- mental Watersheds (KREW) sites demonstrate that precipitation in the form of snow generates greater yearly discharge in a given watershed. The difference in discharge between the KREW Provi- dence site and Bull site is as much as 20 percent per year. C. Hunsaker Research Area Figure 1—KREW’s double flume system. The large flume KREW is a watershed-level, integrated ecosystem project for (background) accurately captures high flows, and the small flume headwater streams in the Sierra Nevada. Eight watersheds at two is successful at measuring lower base flows. study sites are fully instrumented to monitor ecosystem changes. Stream discharge data, just one component of the project, have been collected since 2002 from the Providence site and since 2003 from the Bull site. What is Stream Discharge? Discharge is the amount of water leaving each watershed within the stream channel. It is represented as a rate of flow such as cubic feet per second (cfs), gallons per minute (gpm), or acre-feet per year. -

From the River to You: USGS Real-Time Streamflow Information …from the National Streamflow Information Program This Fact Sheet is one in a series that highlights information or recent research findings from the USGS National Streamflow Information Program (NSIP). The investigations and scientific results reported in this series require a nationally consistent streamgaging network with stable long-term monitoring sites and a rigorous program of data, quality assurance, management, archiving, and synthesis. NSIP produces multipurpose, unbiased surface-water information that is readily accessible to all.

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. -

Real-Time Stream Flow Gages in Montana
REAL-TIME STREAM FLOW GAGES IN MONTANA Montana is home to over 264 real-time stream lows and improve water management practices. It gages located throughout the state. These gages can drive the understanding for other sciences and and their networks assist in delivering water data to helps inform citizens on how we can prepare for scientists and the public. While Montana’s demand changes in our water supply. It is imperative to for water continues to grow, water availability maintain as many gages as possible to preserve varies from year-to-year and can change these historical records for current and future dramatically in any given year. Managing supply and generations. demand challenges is an ongoing feature of life.

These emergency planning and notification. This gages measure the stage (height) of the river in feet, information is generated in Montana by multiple and water temperature along with other networks of real-time stream gages operated by the environmental data. U.S. Geological Survey (USGS), the Department of Natural Resources and Conservation (DNRC), and some tribes. Within each network, the operation and maintenance of gages are financially supported by different sources including federal, state, tribal, local, and private funds. Some of the gages are funded by multiple agencies and organizations. The recorded data are essential to make informed water management decisions across the state. -

Classifying Rivers - Three Stages of River Development
Classifying Rivers - Three Stages of River Development River Characteristics - Sediment Transport - River Velocity - Terminology The illustrations below represent the 3 general classifications into which rivers are placed according to specific characteristics. These categories are: Youthful, Mature and Old Age. A Rejuvenated River, one with a gradient that is raised by the earth's movement, can be an old age river that returns to a Youthful State, and which repeats the cycle of stages once again. A brief overview of each stage of river development begins after the images. A list of pertinent vocabulary appears at the bottom of this document. You may wish to consult it so that you will be aware of terminology used in the descriptive text that follows. Characteristics found in the 3 Stages of River Development: L. Immoor 2006 Geoteach.com 1 Youthful River: Perhaps the most dynamic of all rivers is a Youthful River. Rafters seeking an exciting ride will surely gravitate towards a young river for their recreational thrills. Characteristically youthful rivers are found at higher elevations, in mountainous areas, where the slope of the land is steeper. Water that flows over such a landscape will flow very fast. Youthful rivers can be a tributary of a larger and older river, hundreds of miles away and, in fact, they may be close to the headwaters (the beginning) of that larger river. Upon observation of a Youthful River, here is what one might see: 1. The river flowing down a steep gradient (slope). 2. The channel is deeper than it is wide and V-shaped due to downcutting rather than lateral (side-to-side) erosion. -
