IV. ANALYSIS: IMPLEMENTING SEEPAGE ANALYSES
IV-19
INTRODUCTION
Where and when to use each method of analysis is an important consideration. Sometimes a
visual inspection is adequate to assess a seepage condition. Other times, more detailed
analyses are required.
WHERE AND WHEN TO USE METHODS OF ANALYSIS
Some general considerations when selecting a method of analysis include:
• What point in a dam's history is being considered?
• How complex is the problem?
• What information is available?
• What information can be obtained or is required, and at what cost?
• Is the problem urgent, or is there time for detailed analyses?
Table IV-2 presents example guidelines for using various methods of seepage analysis.
