Computational Hydrology '87

Preface

This book has evolved from the documentation for a specialized water resources program package HYDRAULICS ELEMENTS I developed by Advanced Engineering Software (AES), Irvine, California. The program package has been marketed throughout the world since 1981 and has gained a widespread audience of program users including practicing civil engineers, City, County and State officials, students and university faculty, Besides providing an extensive library of open channel flow hydraulics problem-solving software, the AES program package is an excellent example of the state-of-the-art in user-friendly or 'humanized' software. That is, there is no real need for program documentation: the program is the documentation. All data entry, parameter selection, and program editing features are internal of the program.
This book presents the basic theory which is fundamental to open channel flow hydraulics and then presents the guidelines used by AES in their developmental procedures for a "humanized" software product. Software code (batch mode) is included which provides the powerful library for solving open channel flow hydraulics problems. Finally, several examples are provided to illustrate many of the features and capabilities of the provided codes.
Should the reader elect to key in the provided software codes and operate the programs in the batch mode, a time allocation of approximately forty hours should be planned in order to enter the programs, provide the machine-dependent file manipulation coding (e.g., file open and close statements), "debugging" the programs, and verification of the programs using the many example problems provided in Chapter 5. Another option is to purchase the AES humanized software package directly. The necessary licensing agreement and order information is provided following the book references.
