📚 What’s Covered in This Chapter?
Chapter 2 explores model typology, categorizing different types of environmental models based on their complexity, purpose, and the nature of data involved. You’ll also learn how data mining enhances modelling accuracy and helps in managing massive environmental datasets.
📌 Key Topics in This Chapter:
✔️ Classification Based on Model Functioning
Understand how models are categorized by their functions, such as:
-
Descriptive models – explain environmental systems
-
Predictive models – forecast future outcomes
-
Normative models – assess the effects of decisions
✔️ Spatial Complexity in Environmental Models
Explore how models handle spatial variations in the environment. You’ll learn:
-
The role of GIS and remote sensing in spatial modeling
-
How different land uses or terrain types affect environmental processes
-
Examples like watershed and floodplain modeling
✔️ Physical & Mathematical Complexity
Learn the differences between:
-
Physically-based models – simulate real-world physical laws
-
Mathematically-based models – use equations and algorithms to represent systems
-
Includes examples of hydrological and air dispersion models
✔️ Temporal Complexity in Environmental Models
Time matters in environmental systems! This section covers:
-
Static vs. Dynamic models
-
Short-term vs. Long-term simulations
-
Importance of time-series data and model calibration
✔️ Data Mining Techniques for Environmental Systems
A powerful segment that introduces:
-
Pre-processing: data normalization, standardization
-
Data cleaning: removing errors and inconsistencies
-
Outlier detection: spotting extreme values
-
Missing value treatment: using interpolation or estimation
-
Transformation: log transformations, scaling

🔍 What is a Model in Environmental and Engineering Geology?
A model is a simplified representation of a real-world system, process, or phenomenon. Models help us to understand, simulate, and predict environmental and geological behavior without directly experimenting on the actual system.
In geology, models help engineers and planners to make better decisions about land use, construction safety, hazard prediction, and resource management.
🧩 Why are Models Important in Geomatics Engineering?
As Geomatics Engineers, we deal with spatial data—terrain, elevation, landforms, soil types, and more. We use models to visualize and analyze how natural and manmade factors interact over space and time.
Applications:
-
Landslide Risk Modeling using GIS layers (slope, rainfall, soil)
-
Groundwater Flow Models for mapping aquifers and pollution spread
-
3D Geological Models built from survey and remote sensing data
-
Digital Elevation Models (DEM) used in flood prediction and terrain analysis
📚 Types of Models (Typology)
1. Physical Models
-
Tangible, scaled-down versions of natural systems.
-
Example: A landslide slope built in a lab to test erosion effects.
2. Mathematical Models
-
Use equations to represent real-world behaviors.
-
Example: Using Darcy's Law to model groundwater flow.
3. Conceptual Models
-
Diagrams or flowcharts that describe the relationships among elements in a system.
-
Example: A flowchart showing how rainfall leads to landslides.
4. Statistical Models
-
Use past data to predict future patterns.
-
Example: Landslide susceptibility model using logistic regression in GIS.
5. Computer-Based or Simulation Models
-
Digital models processed using software like ArcGIS, HEC-RAS, SWAT, etc.
-
Example: Floodplain modeling using terrain data and rainfall input.
📌 Example in Nepal’s Context
Let’s say you’re working on a project to map flood-prone areas in the Terai region:
-
You use DEM (Digital Elevation Model) to map low-lying zones.
-
Use hydrological models to simulate river discharge and rainfall.
-
Combine all this in ArcGIS or QGIS to visualize high-risk flood zones.
This is a clear example of a multi-model approach combining geomatics and geology.
🧭 Conclusion
Understanding the typology of models is essential for geomatics engineers. Whether it's predicting natural hazards or designing infrastructure, models allow us to plan smarter and build safer. As students of Environmental and Engineering Geology, mastering these model types will empower you to tackle real-world problems using data and technology.
