Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Stream-Flow Forecasting From Snow Surveys The water content of the snow cover at a given location is reliably determined by measuring the water content of the snow at several points along a snow course. A snow course consists of a series of observation points, usually 10 011 12 in number or enough to give a dependable sampling average. These points are situated at measured spacings of 50 or 100 feet along a permanently marked and mapped route, usually about feet long. The courses are usually located in small mountain meadows. The samples are taken and water con tent is determined at the same locations on each measuring date, year after year. The work is done by a small, skilled corps of professional snow surveyors trained in mountaineering and 111 travel of all kinds over snow. The snow sampler is a lightweight seamless aluminum tube con sisting of easily coupled 30-inch sections. The bottom section is tip ped with a circular saw-edged cutter for penetrating hard snow or icy crusts. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Washichek and published by Forgotten Books. This book was released on 2018-01-11 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Federal-State Cooperative Snow Surveys and Water Supply Forecasts for Colorado River, Platte River, Arkansas River, and Rio Grande Drainage Basins: Issued March 1, 1965 The amount of water stored in mountain snow varies from place to place as well as from year to year and accordingly, so does the runoff of the streams. The best seasonal management of variable western water supplies results from advance estimates of the streamflow. A snow survey consists of a series of about ten samples taken with specially designed snow sampling equipment along a permanently marked line, up to 1000 feet in length, called a snow course. The use of snow sampling equipment provides snow depth and water equivalent values for each sampling point. The average of these values is reported as the snow survey measurement for a snow course. Snow surveys are made monthly or semi-monthly beginning in January or February and continue through the snow season until April, May or June. Currently more than 1400 western snow courses are measured each year. These measurements furnish the key data for water supply forecasts. Streamflow forecasts are obtained by a comparison of total or maximum snow accumulation, as measured by snow water equivalent, to the subsequent spring and summer or snowmelt season runoff over a period of years. The snow water equivalent measured in selected snow courses provides most of the index to the streamflow forecast for the following season. More accurate forecasts are usually obtained when other factors such as soil moisture, base flow and Spring precipitation are considered and included in the forecast procedure. Early season forecasts assume average climatic conditions through the snowmelt season. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from Water Supply Outlook and Federal-State-Private Cooperative Snow Surveys for Colorado and New Mexico: May 1, 1965 The climate of the cultivated and populated areas of the West is characterized by relatively dry summer months. Such precipitation as occurs falls mostly in the winter and early spring months when it is of little immediate benefit to growing crops. Most of this precipitation falls as mountain snow which stays on the ground for months, melting later to sustain streamflow during the period of greatest demand during late spring and summer. Thus, nature provides in mountain snow an imposing water storage facility. The amount of water stored in mountain snow varies from place to place as well as from year to year and accordingly, so does the runoff of the streams.

Book excerpt: Excerpt from Federal-State Cooperative Snow Surveys and Irrigation Water Forecasts: For Colorado River Basin, March 1, 1953 Gunnison River: Snow accumulation to date on the watershed of the Gunnison River is somewhat less than for the Upper Colorado, at 75 Percent of normal. Summer stream flow will probably not exceed that indicated.by present snow measurements. Even if the rate of snow accumulation is normal or above for the remainder of the season runoff will be materially reduced by dry moun tain soils. Soil moisture conditions are reported as fair to good in the Gunnison and Montrose districts, probably due to snow-melt at valley eleva tions. Stream flow is slightly above normal.

Washichek and published by Forgotten Books. This book was released on 2018-09-11 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Federal-State Cooperative Snow Surveys and Water Supply Forecasts for Colorado River, Platte River, Arkansas River and Rio Grande Drainage Basins: Issued May 1, 1966 Most of the usable water in western states originates as mountain snowfall. This snowfall accumulates during the winter and Spring, several months before the snow melts and appears as streamflow. Since the runoff from precipitation as snow is delayed, estimates of snowmelt runoff can be made well in advance of its occurrence Streamflow forecasts published in this report are based principally on measurement of the water equivalent of the mountain snowpack. Forecasts become more accurate as more of the data affecting runoff are measured. All forecasts assume that climatic factors during the remainder of the snow accumulation and melt season as they affect runoff will add to be an effective average. Early season forecasts are therefore subject to a greater change than those made on later dates. The snow course measurement is obtained by sampling snow depth and water equivalent at surveyed and marked locations in mountain areas. A total of about ten samples are taken at each location. The average of these are reported as snow depth and water equivalent. These measurements are repeated in the same location near the same dates each year. Snow surveys are made monthly or semi-monthly from January 1 through June 1 in most states. There are about 1400 snow courses in Western United States and in the Columbia Basin in British Columbia. In the near future, it is anticipated that automatic snow water equivalent sensing devices along with radio telemetry will provide a continuous record of snow water equivalent at key locations.
