Guidelines for determining flood flow frequency-Bulletin 17C

Abstract

An accurate estimate of the flood damage potential is a key element to an effective, nationwide flood damage abatement programme. Further, there is an acute need for a consistent approach to such estimates because management of the nation's water and related land resources is shared among various levels of government and private enterprise. To obtain both a consistent and accurate estimate of flood losses requires development, acceptance, and widespread application of a uniform, consistent and accurate technique for determining flood flow frequencies. The guide is a synthesis of studies undertaken to find methodological improvements and a survey of existing literature on peak flood flow determinations. (A)
