Virtual River: Discharge and Flooding - Geology Labs On-line
Entry ID: Virtual_River-02
Abstract: (Adapted from the Virtual River webpage)
Virtual River consists of two activities (Discharge and Flooding) that help students understand some of the important process of rivers such as discharge and flood frequency The activity about Flooding is in "Beta" Release. A "Demonstration" version is available so that instructors can take a quick tour to see if the activity is appropriate for their ... students.
Welcome to VirtualRiver. Here you will find two interactive exercises designed to help you learn about river processes like discharge,flooding, and flood frequency. Each activity requires you to make careful observations and measurements, do simple calculations, and answer questions about your work. A "Certificate of Completion" will be available to you at the end of each activity.
If this is your first experience with hydrology (the science of the Earth' surface water), complete the exercises in order. Most students can complete an exercise in about 1 to 1.5 hours. You are encouraged to complete River Discharge first.
Use Constraints Technical Considerations and System Requirements
uses the Macromedia Flash plug-in. You must use a Java enabled browser. Virtual
River works best with Netscape Communicator 4.08 or higher on both Windows
... machines and Macs and Microsoft Internet Explorer 4.0 or higher on Windows
machines and Microsoft Internet Explorer 4.5 or higher on Macs. It has been
tested on Netscape Communicator 4.08 and 4.5 on both Windows and Mac as well as
Microsoft Internet Explorer 4.0 SP 1 and 5.01 on Windows and Microsoft Internet
Explorer 4.5 on the Mac. Testing was done on Windows 98/NT and MacOS 8.1 and
8.5 on the PowerPC. Mac users using Internet Explorer should have Apple's MRJ
2.1.4 or higher installed and have Internet Explorer configured to use it as
its Java VM. If you have problems running the Java applets under Microsoft
Internet Explorer for Windows, you should try getting the latest version of the
Microsoft Java Virtual Machine.
Minimum memory requirements are not known at this time. It has been
successfully run on Windows 98 and the Mac OS using Netscape Communicator with
64 MB of RAM. If you are running Netscape on the Mac, you will have more
success with Virtual River if you increase the Suggested Memory Size to 32000K
or more. This doesn't mean that computers and settings with less memory will
not work, but having sufficient memory seems to be critical.
Some of Virtual River's applets are large files that (depending on the speed of
your Internet connection) "may" take more than a minute or two to load into
your computer. Please be patient while these applets are loading.
