Abstract : Drainage and erosion control facilities of 54 installations were observed to evaluate performance of surface and subsurface drainage systems, erosion control measures, and conditions of buried conduits and associated facilities. Specific problem areas, general concepts, and recommendations relative to design, construction, and maintenance of various facilities are presented based on the findings of both field observations and laboratory research. The most frequently encountered problems can be attributed to the lack of and/or adherence to a long-range master plan of development; design deficiencies due to inadequate and unavailable knowledge of certain phenomena, restrictions imposed by time and funding limitations as well as the accuracy of basic data available, and the misguided concept that drainage is the least important factor affecting performance of an installation. Periodic evaluation of field facilities is considered invaluable in identifying problem areas, determining causes of malfunctions, and/or failures as well as effective methods of repair and rehabilitation of existing systems, directing research efforts, and developing improved design criteria.
