Purpose and scope of this bulletin:
a. This bulletin reviews briefly principal classes of flood analyses and estimates involved in the planning and design of flood control and multiple-purpose projects, with the primary objective of indicating the general application and purposes of Standard Project Flood Estimates.
b. Generalized rainfall criteria and recommended procedures for the computation of standard project storm rainfall and rainfall-excess quantities for small drainage basins (classified herein as approximately 1,000 square miles and less located east of 105 degrees longitude, are presented, with a concise explanation of their derivation.
c. Procedures for derivation of SPS and SPF estimates for large drainage basins (exceeding approximately 1000 sq.mi.) are discussed and illustrated.
d. This bulletin is sub-divided into four Sections
