Canal Models and You
Unsteady canal simulation models require serious investments of time and personnel. The reasons for deciding to invest in a model, as well as reasons to not invest, are discussed. Canal...

Numerical Methods Used to Model Unsteady Canal Flow
Investigating the response characteristics of irrigation waer supply and distribution systems is essential if a good design is to be developed. Numerical simulation techniques have been...

Unique Problems in Modeling Irrigation Canals
Irrigation-canal modeling is based on the same unsteady flow equations used for river modeling. However the canal and irrigation environment present several unique simulation problems...

Informed Use and Potential Pitfalls of Canal Models
Numerical models of unsteady flow in canals are used in the design, analysis and operation of irrigation canal systems. Their informed use requires knowledge of the potential pitfalls,...

DUFLOW is a micro-computer software package for simulating one-dimensional unsteady flow in open channel systems. It is designed for simple networks of channels with simple structures....

Description and Evaluation of Program: USM
USM was developed by the USBR for simulating unsteady flow conditions in canals with either manual or automatic gate operation. This paper describes the model and discusses the relative...

Description and Evaluation of Program: CARIMA
The CARIMA code simulates unsteady free-surface flow in simple or multiply connected systems of rivers or canals. The simulation uses the Preissmann implicit finite-difference method for...

The Ala Wai Canal?From Wetlands to World-Famous Waikiki
The Ala Wai Canal, a man-made tidal estuary on the island of Oahu, Hawaii, is located about a half mile (0.8 km) landward of Waikiki beach and is two miles (3.2 km) long. As Hawaii's...
