Notes:
: This paper reviews the processes that occurred during an application of the Metropolitan Water District (MWD)-MAIN water use forecasting system for the City of Salinas, California. The review includes an analysis of sources of available data, methods for estimating input data, calibration, and verification of the MWD-MAIN System, and an evaluation of the reliability of system output. We found that inexperienced users can have difficulty understanding the level of skill, knowledge, and amount of data that are required to produce reliable forecasts.Some of the issues associated with application of the MWD-MAIN System include the following:〈list xml:id="l1" style="custom"〉•All input data needed for accurate forecasts simply are not available for many cities and towns.•The data requirements are more extensive than many users anticipate.•Substantial requirements for manipulation of input data produces opportunity for error that creates major time demands in troubleshooting.•Calibration and verification for specific uses can be substantially more difficult than is readily apparent from the guidance manual.•Independent validity checks need to be done to validate system output.•If specified calibrating procedures do not produce reasonable results, reestimating slope coefficients is an option, but this requires resources and expertise that can easily exceed the limits of most users.These are problems typical of most complex models. Reviews such as this can help users to appreciate the level of data required, and to use the MWD-MAIN System in a more effective and efficient manner.
