DESCRIBE HYDROLOGY AND CALCULATE
Critical Tasks: 01-1990-20-1002
This course describes the proper methods used to design drainage structures for use in the theater of operations
TERMINAL LEARNING OBJECTIVE:
Describe hydrology, its stages, the natural losses that affect it, and its uses; and calculate
drainage areas using the Stripper Method.
You are given the materials contained in this lesson.
Correctly answer all practice exercise questions at the end of each lesson.
The material contained in this lesson was derived from the following publication: Field
Manual (FM) 5-430-00-1/Air Force Pamphlet (AFPAM) 32-8013, Volume 1 (to be
published within the next six months).
As the Army's worldwide mission diversifies, the need for roads and networks, airfields, and other installations
become more and more important. In both wartime and peacetime operations, the mobility of the soldiers,
equipment, and logistics is critical.
Drainage engineering is important to all military construction. The entire serviceability of roads, airfields, and
other installations depend on the adequacy of the drainage system. The objective of a drainage system is to
minimize the effects of adverse weather conditions on operations by--
Removing all surface water from operating areas.
Intercepting and disposing of runoff from adjoining areas.
Intercepting and removing detrimental ground water.
As an engineer officer, you will be responsible for overseeing the construction of these horizontal facilities. This
is particularly true in the TO where small time delays to repair roads and ditches may result in large loss of life
