Answer:
At their best, models can be used to help decision makers evaluate large, complex problems and determine an appropriate course of action. There are many different types of models. Simple physical models such as an aquifer built in an aquarium can help us understand how aquifers function and how they react to different things like rainfall or pollution. Virtual digital simulation models use computers to solve complicated mathematical equations, and they can allow water managers to explore the impacts of various conditions or management plans without actually doing anything that might reduce spring flows or harm endangered species. Complex digital computer simulations can also help us visualize the aquifer in three dimensions and understand how it works. Models may also take the form of financial spreadsheets that analyze costs and benefits. We are going to look at all these types of models here.
Models are usually just one piece of a larger puzzle when we are looking at real-world problems from a systems analysis approach. Systems analysis is a philosophy of problem solving most often used with large, complex problems where a decision maker collects information and uses everything available to decide what to do. It is not a cookbook approach or a box where we insert data, turn a crank, and get an answer. There are basically three types of questions that modeling addresses, and systems analysis usually involves solution processes and modeling designed to get answers to questions of the third type:
