Site Engineering for Landscape Architects: Designing and Sizing Storm Water Management Systems

Start Date
End Date
The purpose of managing runoff is to ameliorate safety and health hazards, including flooding and property damage, stagnation, earth slides, and reduced soil-bearing capacity, to increase the usability of areas through the elimination of unwanted water, to provide better growing conditions for plants by increasing soil aeration, and reducing soil saturation and to prevent erosion by reducing the rate of flow and volume of runoff. There are a variety of management techniques that may be used to control storm water runoff. The purpose and environmental conditions will influence the selection of appropriate techniques. This course will discuss storm water management, soil erosion, and the design and sizing of management systems, with particular emphasis on the Rational, Modified Rational, and TR55 Natural Resources Conservation Service methodologies.
