TM 5-820-1/AFM 88-5.1, TECHNICAL MANUAL, SURFACE DRAINAGE FACILITIES FOR AIRFIELDS AND HELIPORTS (20 AUG 1987)., This manual prescribes standards of design of surface drainage of airfields and heliports. Problems involved in the design of drainage facilities are discussed, and convenient methods of estimating design capacities are outlined. These standards can be altered when necessary to meet special problems or unusual conditions on the basis of good engineering practice. Design of drainage facilities for arctic or subarctic regions is discussed in TM 5-852-7/AFM 88-19, Chap. 7 (see app A for referenced publications).
