  • SRC Engineering works to increase the navigability of rivers can only be advantageously undertaken in large rivers with a moderate fall and a fair discharge at their lowest stage , for with a large fall the current presents a great impediment to up - stream navigation , and there are generally great variations in water level , and when the discharge becomes very small in the dry season .
  • SRC Rivers whose discharge is liable to become quite small at their low stage , or which have a somewhat large fall , as is usual in the upper part of rivers , can not be given an adequate depth for navigation purely by works which regulate the flow ; their ordinary summer level has to be raised by impounding the flow with weirs at intervals across the channel , while a lock has to be provided alongside the weir , or in a side channel , to provide for the passage of vessels .
