Abstract
The reverse problem of computing the shape of a weir profile for achieving an assumed discharge-head relation is solved. In a logarithmic weir, the discharge is proportional to the logarithm of the head measured from a certain datum. This weir needs a compensating bottom since its discharge-head relation involves a term of head which has less than 3/2 power. Different shapes of compensating bottoms as provided earlier in a linear proportional weir are also fitted for the logarithmic weir. The ranges of logarithmic weir profiles have been increased for the purpose of passing a design discharge under weir flow condition. This has been achieved with the help of an arbitrary number introduced into the discharge-head relation. Experiments were conducted on two typical logarithmic weirs that yielded a value of 0.60 for the coefficient of discharge.
