Abstract

DESIGN OF WATER RESOURCES ENGINEERING PROJECT IS ALWAYS UNDER UNCERTAINTIES.THIS FACT BEARS IMPORTANT CONSEQUENCES WHEN THE OPTIMAL DESIGN IS SOUGHT.THE UNCERTAINTIES OFTEN COMPLICATE THE DETERMINATION OF THE OPTIMAL DESIGN, AND PROBABILISTIC CONSIDERATION IS GENERALLY A NECESSITY.TO ILLUSTRATE THIS POINT, OPTIMAL DESIGN OF A BRANCHED STORM SEWER SYSTEMS IS USED AS AN EXAMPLE.THE RESULT DEMONSTRATES THE RELATIVE IMPORTANCE OF AND SENSITIVITY TO THE ACCURACY OF THE DATA ON RAINFALL, TRANSFORMATION OF RAINFALL TO RUNOFF, SEWER SIZE, CHANGE IN ROUGHNESS, ACCURACY OF DESIGN EQUATIONS, AND DESIGN DURATION AND RETURN PERIOD OF RAINFALL.THE METHOD CAN BE APPLIED TO OTHER WATER RESOURCES SYSTEMS AND THE RESULT CAN IDENTIFY THE MOST CRITICALLY NEEDED DATA AS WELL AS THE WORTH OF THE DATA.(A)
