This book was released on 1969 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Generalized estimates of precipitation are necessary for consistent spillway design for projects within any given region. The Tennessee Valley Authority is giving increased emphasis to this approach. Toward this end the present report provides generalized estimates o f1- to 72-hr. precipitation extremes for basins ranging in size from a few square miles to about 3000 miles. Antecedent rainfall criteria are provided also for use as indices to soil moisture conditions and existing streamflows at the beginning of critical rainfalls. The detailed probable maximum precipitation estimates of this report supersede within the Tennessee River watershed previous generalized estimates published in Hydrometeorological Report No. 33.
