A Guide to Select the Right Type of River Models
River models and tables have been used for scientific studies for a long time. The modern tables have become more interactive to facilitate the simulation-based research of fluvial systems at every level. With the right type of river models, you can explain the complexities of river systems to the learners in a comfortable environment within the classroom settings.
From water erosion to hyporheic flows, explain every concept in an acceptable method with these tables. They are versatile enough to suit the learning goals of Ph.D. students and preschoolers at the same time. However, it requires the selection of the right type of models as well. Here are the factors to keep in mind:
Choose the Right Dimensions
If you use river models in a limited dimension with a narrow width, it may not be adequate to understand the complex fluvial systems in a lucid manner. Hence, choose a river table that has appropriate dimensions for displaying soil erosion, meandering, and sediment formation.
Look for Durability and Maintenance Needs
In your science experiments, the river tables may undergo a lot of handling pressure and stress. Ensure their durability by choosing tables made from sturdy materials. Prefer those having engineered aluminum boxes and epoxy bases to sustain the handling.
The best types of models can handle heavy loads with ease for ensuring better learning without any limitations. Also, look for the maintenance needs of the models before selecting them. Choose the river tables that can last longer with minimum maintenance.
Consider the Instruments and Accessories
Every river or stream model comes with some instruments that facilitate a better understanding of various fluvial processes. Choose the essential devices like wavemaker, flow controller, tilting base, media feeder, groundwater system, and dye injection system.
Each of these accessories helps to visualize the processes in an interactive and simulated environment. You can control every part of the experiment, including:
- Wave formation for coastal geomorphology
- Rapid changes of the valleys by tilting the bases
- Flow patterns for water movement
- Subsurface flow patterns
- Sediment supply through media feeders
Select the Appropriate Modeling Media
Modeling media facilitates proper visualization and understanding in a river system, especially the sediment formation and transportation. Instead of choosing heavy media particles that can weigh down the table, select the models using plastic media in varied sizes. Processed plastic has a density of up to 60% of the quartz sand. So, it can demonstrate various aspects and processes of fluvial geomorphology in every scale.
When the media is lightweight and easy to transport, it doesn’t exert pressure on the mechanical parts like flow pumps as well. As a result, your models are easy to clean and maintain. Also, look at the color-coding of the modeling media to ensure a basic understanding of each process through clear identification.
Look for the Instructive Material
When you install the river models in your classroom, you may need active support and guidance for running various experiments. Hence, choose the models that come with complete instructive material, including manual, teaching notes, and informational DVDs.
Consider these points to choose the right type of river table models for your science classes.
