An Introduction to Seepage and Drainage

COURSE NO: G05-005
An Introduction to Seepage and Drainage
Course Highlights

This online engineering PDH course provides an introduction to seepage and drainage control for foundations and earth structures. It covers surface erosion, and analysis of flow quantity and groundwater pressures associated with underseepage.  It also presents the requirements for methods of drainage and pressure relief.


Control of soil erosion must be considered in all new construction projects. Seepage pressures are of primary importance in stability analysis and in foundation design and construction. Frequently, drawdown of groundwater is necessary for construction. In other situations, pressure relief must be incorporated in temporary and permanent structures.   For erosion analysis, the surface water flow characteristics, soil type, and slope are needed. For analysis of major seepage problems, permeability and piezometric levels should be determined by field observations.


This 5 PDH online course is intended for civil engineers, structural engineers, geotechnical engineers, geologists and other design and construction professionals seeking an introduction to methods and techniques for seepage and drainage control for foundations of structures, and earth structures such as dams, reservoirs and levees.

Learning Objectives
