Abstract: The paper describes a procedure for direct, optimal fitting of the log‐Boughton frequency distribution to either complete sets or subsets of annual flood data. The analytical basis and derivation of the procedure are given. ...

Abstract: A numerical procedure is developed for quickly and accurately finding the location and flow depth of a flow transition (critical control section) in open channels with discharge gradually varying along the channel length. ...

Abstract: The general problem of solving for normal flow depth in open‐channel flow has a complication in that some types of channel cross sections do not always have a unique solution. This paper analyzes an alternative iterative ...

Abstract: We develop an approximation of the Green‐Ampt infiltration equation by using the first two terms of a Taylor‐series expansion of the equation. The resulting approximate equation is in the form of the Philip's equation, ...
