M PREFATORY NOTE
5-7 This volume is the fifth of a series of Technical Reports issued in connection with the planning and execution of a notable system of flood protection works in the Miami Valley.
This valley which forms a part of the large interior plain of the central United States and comprises about 4,000 square miles of gently rolling topography in southwestern Ohio, is one of the leading industrial centers of the country. The immense damage which it sustained during the flood of March, 1913, amounting to 100 million dollars of property and over 360 lives, led to an energetic movement to prevent future disasters of this kind. This movement developed gradually into a great cooperative enterprise for the protection of the valley by one comprehensive project. The Miami Conservancy District, established in June, 1915, under the newly enacted Conservancy Law of Ohio, became the agency for securing this protection. On account of the size and character of the undertaking, the plans of the district have been developed with more than usual care.
A Report of the Chief Engineer, submitting a plan for the protection of the district from flood damage, was printed, March, 1916, in 3 volumes of about 200 pages each. Volume I contains a synopsis of the data on which the plan is based, a description of its development, and a statement of the plan in detail. Volume II contains a legal description of all lands affected by the plan. Volume III contains the contract forms, specifications, and estimates of quantities and cost.
After various slight modifications this report of the Chief Engineer was adopted by the Board of Directors as the Official Plan of the District, and was republished in May, 1916.
In order to plan the project intelligently, many thorough investigations and researches had to be carried out, the results of which have proved of great value to the District, and which will also be of widespread value to the whole engineering profession. The object of publishing this series of Technical Reports is to make available to the residents of the state and to the technical world at large, all data of interest relating to the history, investigations, design and construction of the project.
The following reports, prepared by the engineering staff of the District, have been completed:
