Gate structures for irrigation canals /

Аннотация

A study of the irrigated regions of the West shows that the designs _ and special features of structures have been copied and adapted one _ from another, but usually within the bounds of one locality. Two | sections with quite similar conditions show great divergencies in | structures used for the same purposes. This is true largely for the " reason that those who design the structures have neither the time nor _ the means to travel and learn how others are handling similar situaf: tions. The purpose of this bulletin is to bring together designs | adapted to many localities, in order that the practice of the whole | country may be available to those who design structures.
