It would be very helpful if we could somehow predict when and Learning unit 1 reading future earthquakes will happen, but in order to do so, we need a better understanding of what causes faults to slip. Steady state systems are characterized by inflows and outflows that are in complete balance such that no change occurs over time in the total amount of material contained within the reservoir.

Models are used widely in Earth and environmental science research because many of the questions of interest in these disciplines present spatial and temporal challenges that prevent us from addressing them directly. Let us assume that the aquifer is unconfined and that it has an impermeable layer, called an "aquitard," at its base.

The percentage we would be looking for then would be: The first step is to integrate both sides: Let us call the base flow value D for discharge, the aquifer water volume V, and the percentage k.

This image comes from the following USGS report: Let us assume, for example, that the precipitation arrows in our conceptual model have a value of 0. These images are Figure SPM. Career success in a global economy depends on a strong education; for all segments of U.

It is not immediately clear how to represent the discharge from the aquifer, but to a first approximation, we know that it must depend on how much water is in the aquifer — the more water in the aquifer, the greater the discharge — and we could begin by saying that the discharge will be a certain percentage of the water in the aquifer.

These images come from a USGS webpage http: To begin the modeling process, we create a sketch that represents our conceptual model of the aquifer system.

Some processes occur so slowly that they are nearly impossible to detect. We can, however, create numerical models that simulate fault behavior through equations that describe the buildup and release of elastic energy as well as the role of bumps on the fault plane that generate frictional resistance to sliding see for example Ghosh and Holt, ; Jolivet et al.

Simulate processes too slow to permit human observation. We always start with a question that involves some kind of system changing over time.

Systems may be open, in which case they exchange both matter and energy across their boundaries, or closed, in which case only energy crosses Fig. Results of numerical modeling experiments published in the Intergovernmental Panel on Climatic Change Assessment Report 5 indicate that increasing greenhouse gas levels will lead to a warmer planet with more variable precipitation values.

Now that we have sketched our model, we need to figure out what the units are for the various parts of the system. To do this, we incorporate a second outflow from the groundwater in aquifer reservoir that will remove water from the system for a limited period of time Fig.

A system that prohibits both matter and energy from crossing its boundaries is known as isolated, but is just a hypothetical construct that does not exist anywhere in the known universe. Numerical models that employ equations to describe a variety of erosional processes have been used to simulate landscape evolution, with the results compared to known topographic features in order to determine the rates at which these processes operate.

To test the model, we can run it and graph the aquifer reservoir and the water table height, both of which should stay constant over time since we designed this model with the assumption that the aquifer system is in a steady state.

Having convinced ourselves that the model is working correctly, we can now go on to explore the impact of pumping on the aquifer volume.In Unit 1 you will learn to greet and say good-bye to somebody.
