  • Impact of IT on river modeling

    Background Models of river channels and river flows have been used to good effect for many years. HR Wallingford Group, in the UK, has been building physical models of rivers for nearly 60 years. Some years ago, it was predicted that physical modeling would soon cease to exist, to be entirely replaced by computer models. This has not happened - in fact, the demand for physical models is greater ...
