Excerpt from Hydrographic Surveying: Methods, Tables and Forms of Notes In offering this Manual to the public, the author ventures to hope that the information contained herein may be useful to engineering students and to the younger members of the profession as well as to those engineers of larger experience who are not thoroughly familiar with the minor details of Hydrographic Surveying. The author is conscious of the fact that much of the matter contained in the manual is elementary and that the hydraulic formulas are stated as nearly as practicable in their simplest forms. While this is true, it is believed that the subject under consideration, hydrographic surveying, does not require profound discussion, and that plain, direct treatment of the subject matter will be productive of the best results. No attempt has been made to introduce complicated mathematical formulas into the text since it is believed that ultra refinement in a hydraulic formula for discharge would be out of place in view of the impossibility of making ordinary field measurements with microscopic exactness. It has not been thought necessary to go deeply into theoretical or scientific derivations of causes and effects of phenomena connected with the flow of water. Such matters are fully covered in works on hydraulics, of which there are a number of excellent examples. It is the author's purpose to explain the practical features of hydrographic surveying, such as are likely to be encountered by the surveyor in actual practice and such as are at present to be learned only by actual field experience in this class of work. Much of the information contained in this manual was acquired by the author in the course of his professional work, and consequently has the merit of practicality. The author has endeavored to limit the scope of this manual to such ordinary methods of hydrographic surveying as are likely to come within the practice of the hydrographic surveyor. It is desired that this little book will consitute a practical paper on surveying as applied to hydrographic work, and to embody therein a concise explanation of modern methods of practice.
