Week 2: Reading 2a and 3 Flashcards

1
Q

Name and describe the two modeling objectives for water demand

A

Existing Systems: develop a model to accurately simulate operation of exisiting system

Proposed Systems: develop a model that will become a planning tool to guide design of future system

Q

What is the difference between macro and microscale models of demand?

A

Macroscale models are used to estimate overall water demand, treatment facilities, and system storage

Microscale models are used to estimate water demand for specific system such as a pumping station used for fire protection
