Improvements in medical technology and improved lifestyles around the globe have resulted in the population growth trend we
see today. The outcome is an ever-increasing demand in construction activities, be it for housing purposes or to provide for
additional infrastructures to sustain the population growth and improved lifestyles. Indirect impact of this increase in
construction activities is an increase in soil erosion from these (construction sites) activities, accelerating the global
threat posed by massive soil erosion from human induced activities.
While little, if any, can be done to stop the natural erosion process, timely actions can be taken to reduce erosion
resulting from construction activities. The constraint, however, is to strike a balance between adverse economic impacts and
associated environmental hazards. This is where effective use can be made of mathematical models specifically developed
with aims of predicting soil erosion. For construction activities, these mathematical models can be used to compare adverse
impacts of different management practices, with the objective of choosing the most appropriate (i.e. Best) Management
Practice (BMP) for minimizing adverse environmental effects.
With a plethora of erosion models available, with varied degree of data requirements and associated reliabilities, the
dilemma planners and managers face in selecting a set of BMPs for reducing soil erosion from construction activities is the
selection of a suitable model itself. This paper addresses this dilemma through selection of a simple yet reliable model
that will assist the planners, developers and decision makers in comparing impacts of a range of management practices. The
result is the selection of management practices that will meet the economic requirements without causing adverse
environmental impacts.
