Download or read book THE ROLE OF CLIMATE VARIABILITY IN OPERATIONAL WATER SUPPLY FORECASTING FOR THE WESTERN UNITED STATES written by and published by . This book was released on 2005 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: The single greatest uncertainty in seasonal water supply forecasts is the amount of precipitation falling after the forecast issue date. There has been a long history of attempting to incorporate seasonal climate forecasts into operational water supply forecasts. The skill of these precipitation forecasts remains low especially compared to highly confident snow-based streamflow forecasts. Early in the season (e.g., September-December), however, large-scale climate indices are the best available predictors of future water supplies. This dissertation suggests practical methods for issuing climate-based operational streamflow forecasts. This study also documents the existence of strong decadal trends in water supply forecast skill. Across the Western US, 1 April forecast skill peaked in the 1960-1970s and has been on the decline more recently. The high skill period was a very calm period in the Western US, with a near absence of extreme (wet or dry) spring precipitation events. In contrast, the period after 1980 has had the most variable, persistent, and skewed spring and summer streamflows in the modern record. Spring precipitation is also now more variable than it has been since at least the 1930s. This rise in spring precipitation variability in the Colorado/Rio Grande Basins and the Pacific Northwest is the likely cause behind the recent decline in water supply forecast skill.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the standard reference based on roughly 20 years of research on atmospheric rivers, emphasizing progress made on key research and applications questions and remaining knowledge gaps. The book presents the history of atmospheric-rivers research, the current state of scientific knowledge, tools, and policy-relevant (science-informed) problems that lend themselves to real-world application of the research—and how the topic fits into larger national and global contexts. This book is written by a global team of authors who have conducted and published the majority of critical research on atmospheric rivers over the past years. The book is intended to benefit practitioners in the fields of meteorology, hydrology and related disciplines, including students as well as senior researchers.

Book excerpt: Excerpt from Water Supply Outlook for Western United States: Including Columbia River Drainage in Canada and Federal-State-Private Cooperative Snow Surveys; As of Mar. 1, 1967 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 I 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. Al'l 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 I through June I 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. Detailed data on snow course and soil moisture measurements are presented in state and local reports. Other data or reservoir storage, summaries of precipitation, current streamflow, and soil moisture conditions at valley elevations are also included. The report for Western United States presents a broad picture of water supply outlook conditions, including selected streamflow forecasts, summary of snow accumulation to date, and storage in larger reservoirs.

This book was released on 2018-01-11 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Water Supply Outlook for Western United States, Including Columbia River Drainage in Canada: April 1976 The California Department of Water Re sources reports that supply conditions have deteriorated even further during March-the fourth month this season with below average precipitation. The below normal forecasts of snowmelt for the Central Valley have now been reduced to 30 percent of average for San Joaquin Valley streams and 45 percent for Sacramento Valley streams. Streams draining the east slope of the Sierra Nevada will fare no better. These rivers are also forecast to yield only one third to one-half their normal amounts. However, where users have supplemental supplies from reservoirs, the shortage will not be too severe. Most other regions of the Great Basin should receive adequate to above average supplies. The Columbia Basin continued to receive average to above normal snowfall at high elevations, and the region-wide accumulation is now about 13 percent above the April 1 average. The Columbia is forecast to yield llo percent of its 15-year normal during the april-september period. Nearly all tribu taries will discharge at normal or greater rates. The only exception is in the Big lost-little Wood area of Central Idaho where runoff will fall lo-ls percent below normal. Reservoir storage will alleviate any late season shortages in the area.

Book excerpt: Excerpt from Water Supply Outlook and Federal-State-Private Cooperative Snow Surveys for Western United States, Including Columbia River Drainage in Canada: As of May 1, 1964 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. 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.
