Forecasting Municipal and Industrial Water: IWR MAIN System User's Guide for Interactive Processing and User's Manual.

摘要

This two volume report comprises the necessary information to effectively use a computerized procedure for estimating and forecasting municipal water requirements. The procedure, known as the IWR MAIN System, is a flexible and comprehensive planning tool for separately estimating residential, commercial/institutional, industrial, and public-unaccounted water sectors in a community. Within these sectors, requirements are further estimated for individual categories of water users, such as metered-sewered residencies, flat rate-sewered residences, commercial establishments, institutions, three-digit Standard Industrial Classification manufacturing categories, public usage and free service as well as unaccounted use. Estimates are made of mean annual, maximum day, and peak hour requirements. Volume I contains the users guide for interactive processing. It is the procedure by which a user creates or modifies data parameter files, modifies the library of water usage coefficients, runs the IWR MAIN Model, and selectively prints reports generated by the model. Volume II is the users manual. It documents the computer program and presents instructions for data preparation.
