Abstract
Despite the title, this engineer intelligence guide (EIG) is a photo-interpretation handbook. It was intended to help photo-interpreters recognize streams, rivers, lakes, and other hydrologic features. The introduction says that the purpose is:
a) To give “the officer responsible for furnishing hydrologic and hydraulic data in an assigned area … an understanding of the usefulness and limitations of photography in furnishing the type of information needed …,” and to assist in planning requests for photographic coverages of the assigned area.
b) To give “photo-interpreters sufficient knowledge of hydrology and hydraulics to be able to satisfy requests for information that can be secured from photographs and become aware of the need for communicating changes in … conditions, such as, breaks in levees, sudden drawdown or filling of reservoirs, rising water in rivers, and formation and breakup of ice jams…”
It contains extensive guidance in preparation of requests for photographic missions.
It contains detailed information on the value of photographs as sources of hydrologic and hydraulic data.
This EIG contains detailed information with extensive illustrations to assist in interpretation of hydraulic characteristics of watershed, hydraulic characteristics of streams, and of hydraulic structures such as dams, hydroelectric plants, canals, irrigation systems, flood control structures, etc.
It contains a bibliography of literature related to military hydrology and the application of aerial photography to understanding hydrologic features.
It contains an lengthy distribution list of officials and organizations within the Army interested in military engineering.
