Abstract
THE heavy rainfall and snowstorms of last month, culminating in the overflow of the Thames in London on Jan. 7, with grievous loss of life, has brought vividly before the nation the subject of the control and disposal of surplus water. In Great Britain, the problems, although serious, are not of the same magnitude as elsewhere. The disastrous Mississippi floods of last summer, and the extensive damage done around Bagdad when the Tigris broke its banks about two years ago, are illustrations of a menace the full force of which is happily spared us. In these cases the fundamental cause is the gradual raising of the river bed in its lower reaches by the suspended material brought down from the uplands and deposited when the speed of the current is reduced.
