Implementing the Water Balance Approach on Vancouver Island: Desired policy outcomes in transitioning drainage practice from “voodoo hydrology” to the Water Balance Methodolgy would be less flooding, less stream erosion, more streamflow when needed most ….and reduced life-cycle costs and risks!
Andy Reese coined the term Voodoo Hydrology in 2006 to describe drainage engineering and stormwater management practice. “We have for years relied upon common design methodologies and trusted their results. But, should we? It is an inexact science at best. We rely on judgment and guesswork,” states Andy Reese. He is an American water resources engineer & textbook author. “Perhaps, if we make enough estimates of enough factors, the errors will average out to the right answer. This is where voodoo really comes in handy.”
