Available in PDF, EPUB and Kindle. Book excerpt: "A flash flood is a flood in which the rapid rise in stream level and the resulting inundation follows the observable causative event by about four hours or less. For rain-caused flash floods meteorology is complex, and limited amounts of real-time data make timely forecasts of exact location very difficult. Lack of reports of flash-flood occurrences adds to the difficulty. Many occur that are never reported to the National Weather Service (NWS)"--Introduction.

Available in PDF, EPUB and Kindle. Book excerpt: Two commonly used methods of hydrologic analyses are parametric reconstruction and development of frequency distributions. Both techniques can be used to develop estimates of potential of damaging flash floods. However, under conditions of limited data, many areas may not have experienced enough flash floods to be recognized as prone to flash flooding. This paper gives a method to infer expected severity for flooding based on frequency analysis, which does not require a complete spectrum of data over a given basin. This method was used to estimate potential peak flows on Sabino Canyon, Arizona, and probability of occurrence of specified magnitudes was analyzed. These estimates indicate a strong possibility of damaging flash floods occurring in areas where none have occurred in several decades.

Available in PDF, EPUB and Kindle. Book excerpt: "On August 14 and IS, 1976, heavy thunderstorms moved through northern California. The heaviest area of precipitation was in the area west and north of Redding, California. The rain felI at such a rapid rate that normal drains could not handle the water and several areas of the city received water and mud damage from the overflow. The Army Corps of Engineers dispatched personnel to the Redding area to compiIe and verify rainfalI amounts measured by the local residents. Their findings showed rain amounts in excess of 8 inches, with rainfalI rates of 2-1/2 inches per hour. This paper discusses the synoptic pattern preceding and during the thunderstorms. The precipitation pattern is discussed, using the radar displays from the WSR-57 radars at Medford, Oregon and Sacramento, California"--Introduction

Available in PDF, EPUB and Kindle. Book excerpt: Post-World War II Oregon was a place of optimism and growth, a spectacular natural region from ocean to high desert that seemingly provided opportunity in abundance. With the passing of time, however, Oregon’s citizens — rural and urban — would find themselves entangled in issues that they had little experience in resolving. The same trees that provided income to timber corporations, small mill owners, loggers, and many small towns in Oregon, also provided a dramatic landscape and a home to creatures at risk. The rivers whose harnessing created power for industries that helped sustain Oregon’s growth — and were dumping grounds for municipal and industrial wastes — also provided passageways to spawning grounds for fish, domestic water sources, and recreational space for everyday Oregonians. The story of Oregon’s accommodation to these divergent interests is a divisive story between those interested in economic growth and perceived stability and citizens concerned with exercising good stewardship towards the state’s natural resources and preserving the state’s livability. In his second volume of Oregon’s environmental history, William Robbins addresses efforts by individuals and groups within and outside the state to resolve these conflicts. Among the people who have had roles in this process, journalists and politicians Richard Neuberger and Tom McCall left substantial legacies and demonstrated the ambiguities inherent in the issues they confronted.
Download or read book Costs of alternative pollution control policies affecting open field burning in the Willamette Valley of Oregon written by Jagjit Singh Brar and published by . This book was released on 1972 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Open field burning is the lowest-cost method of harvest residue disposal used extensively by grass seed producers in the Willamette Valley of Oregon. The beneficial effects of open field burning include effective disease control and increased seed yields. However, smoke produced by open burning in the late summer pollutes valley air, reduces visibility, and possibly poses traffic and health hazards. The growing concern among Oregon citizenry coupled with increased national interest in environmental quality has led Oregon authorities to legislate controls on open field burning. However, such controls by changing resource allocation in Oregon's seed industry would impose costs upon society. The major objective of this study was to estimate costs of three alternative field burning control policies in terms of the changes in consumers' surplus and producers' rents associated with each policy. To accomplish this objective an econometric model of demand and supply relationships for the six grass seeds raised in the Willamette Valley was developed. To establish a reasonable range for policy-induced changes in consumers' surplus and producers' rents, three alternative supply situations were postulated, and costs of grass seed production under each policy were assumed to increase by $5.00, $9.00, and $13.00 per acre, respectively. Supply situation I assumed positively-sloped Oregon and non-Oregon supply curves whereas situation II assumed a perfectly inelastic Oregon supply curve and a positively-sloped non-Oregon supply curve. Supply situation III postulated a perfectly elastic non-Oregon and a positively-sloped Oregon supply curve. In supply situation I, depending upon policy and assumed increase in costs of seed production, the relative decrease in consumers' surplus varied from 3 to 15 percent at national level when aggregated over all six grass seeds. Oregon producers' rents were predicted to decline by 4 to 20 percent. The increases in non-Oregon rents under each policy and assumed cost increase were only about 20 percent of the losses in Oregon rents. Consequently, the relative decreases in the sum of consumers' surplus and producers' rents (Oregon and non-Oregon) were approximately equal to the decreases in consumers' surplus. Since under supply situation II and III seed prices remained unchanged, only changes in Oregon producers' rents needed estimation. Decreases in Oregon rents in situation II were 6 to 12 percent smaller than in situation I. In contrast, the results for supply situation III suggested that, other things equal, the greater the responsiveness of non-Oregon supplies to price, the greater the losses in Oregon producers' rents. To provide additional perspective on the possible economic impacts of regulating open field burning, changes in earnings in grass seed production were translated into changes in the value of agricultural land now in seed production in the Willamette Valley. To accomplish this objective, the relative decreases in seed production earnings were estimated for supply situations I and II, and a model of the determinants of Willamette Valley grass seed land values was developed. The model predicted that land values in the Willamette Valley would typically decline by approximately two to nine percent depending upon the type of controls imposed on open field burning and the associated cost increase. Although the methodological approach followed in this study is traditional, new measurement techniques are employed to estimate changes in the economic well-being of grass seed producers in Oregon. Furthermore, the extension of partial welfare analysis to predict the effects of Oregon's regulatory policies on the well-being of non-Oregon producers also distinguishes the findings of this study from those of other studies with similar methodological approaches.
