how can compute the water year ratio that I need to input in WEAP. I have done the 5 bins and I know which years are normal, wet, dry. but I cant figure out how to find the ratios.

These ratios are up to you. Suggested values are in WEAP by default. There is really no "right" answer--if you use lower numbers for Very Dry and larger values for Very Wet, it just means that you are modeling more extreme years. You can also vary the ratio throughout the year (by month) if that is more representative of your local weather patterns.
