PREDICTION OF THE MAGNITUDE AND FREQUENCIES OF FLOODS IN MICHIGAN

THE FIRST PORTION PROVIDES A BRIEF HISTORICAL REVIEW OF THE TOTAL RESEARCH EFFORT RELATED TO SURFACE RUNOFF PROCESSES. THIS IS FOLLOWED BY AN OUTLINE OF THE PRESENT STATE OF THE ART INCLUDING A BRIEF DISCUSSION OF OTHER METHODS OF APPROACHING THE PROBLEM. THE AMOUNT OF EFFORT REQUIRED TO GATHER DATA FROM SMALL URBANIZED AREAS IS DISCUSSED AND THE PROCEDURES DEVELOPED TO ANALYZE RAINFALL HYETOGRAPHS AND RUNOFF HYDROGRAPHS TO DETERMINE THE SURFACE RUNOFF HYDROGRAPH AND INFILTRATION CAPACITY ARE DESCRIBED. METHODS OF COMPUTING INFILTRATION CAPACITY AND ITS VARIATION WITH TIME AND LOCATION ARE DISCUSSED. PROGRESS IN LEARNING ABOUT THE FACTORS WHICH INFLUENCE SURFACE RUNOFF HYDROGRAPH SHAPE IS PRESENTED IN SOME DETAIL. THE DEVELOPMENT AND USE OF A MATHEMATICAL WATERSHED MODEL IS ALSO REFERRED TO IN THE DISCUSSION. CURRENT AND FUTURE INVESTIGATIONS WHICH ARE BEING PLANNED TO IMPROVE THE NEW TECHNIQUES ARE DESCRIBED BRIEFLY. THE FINAL SECTION PRESENTS THE WORKING METHOD INCLUDING THE MOST RECENT INPUTS OF NEW DATA. /AUTHOR/
