Abstract

Types of hydraulic systems for filling and emptying navigation locks are described and the general conditions that dictate the use of the various types are examined. In the interests of economy in construction, a wall port system is usually selected in preference to a bottom lateral system wherever operation conditions will permit. In relatively high lift locks (over 50ft) with minimum cushion depths that will be operated at normal filling rates, the bottom. Lateral filling system is generally used. Although this system operates well at lifts, considerable economy can be obtained with wall port systems where lower lifts or deeper' water cushions are encountered. Wall port systems are adopted cautiously and in many instances the selection is made only after verification by model tests. An ideal filling condition in a lock may be obtained by introducing flow uniformly over the entire chamber. An economical approximation of this ideal has been achieved by means of the so-called split-lateral system. This consists of a group of lateral culvert diffusers located in the approximate middle. Third of the upper half of the lock distributing inflow from one wall culvert and another group of laterals in the corresponding location in the lower half of the lock chamber, distributing flow from the other wall culvert.
