Real Time Simulation

In previous chapter we discussed about the Models required and discussed fundamental models . In This chapter I will discuss about Real Time Simulation:

Real Time refers to current(this) time. Basically we have all three models but these are separate. To combine those we need a platform or more specifically a real time platform. This platform will run simulation at current time.

Different softwares have different real time platform. You can also create your own real time platform using scripts( will be discussed later) or you can choose any platform and customise it according to your requirements. Mike has Mike Customised . HEC has HEC RTS. I will demonstrate HEC RTS (open source). HEC RTS is real time platform provided by U.S. Army Corps of Engineers. With HEC RTS you can run every HEC software from a single window. HEC RTS interface is shown below:

In this you have to create watershed and then register the models you want to run. You also have to specify the details like order of the models (HMS ,RAS, RESSim or HMS , ReSSim etc.), the data connections. After adding the models the interface looks like this:

From the above bar you can open HMS, RAS , ResSim, DSS, FIA , FDA etc. You can also add other softwares such as Riverware which can be added as plugin. Other features include you can add scripts , you can schedule your scripts using jobs. You can also add beep and other type of alarms (email etc.)  The flexibility of RTS is extraordinary.

You can add multiple models, different scenarios to specify your needs. These scenarios can be used in different combinations. An image of  as shown below:

You can also add your own customised scripts for data acquisition, decoding, processing and even running the simulation. Then you can schedule them or run manually.

In next chapter I will discuss about Real Time Simulation for forecasting flow using different scenarios.
