About This Book

An engineering proposal argues for construction of a barrage across the lower Thames between Gravesend and Tilbury to create a non-tidal inland reservoir and maintain consistent deep navigation to central London, eliminating dredging, tide-waiting, and grounding, and improving safety and loading operations. The pamphlet catalogs complaints about inadequate depth, delays, overlapping authorities, high costs, and hazardous navigation, critiques dredging and administrative reforms as insufficient, surveys analogous international proposals, and advocates dockisation with locks and sluices as a comprehensive remedy while discussing technical, economic, and operational implications.

The Depletion of the Thames Basin.

This, which has been increasing for many years, is becoming a serious matter, and has attracted much comment. One of the advantages that will be obtained from the barrage will be the raising of the underground water-levels in the chalk and other strata of the Thames basin. In this way a permanent improvement in the water supply by wells throughout this large area will result.
