11.4.1. Hydrological Modeling with GIS

Try these first

1. 1.

   What does GIS stand for?

   Hint

   Think about what kind of information GIS deals with.

2. 2.

   Define a watershed.

   Hint

   Consider where rainwater flows when it falls on land.

3. 3.

   What does HEC-HMS stand for?

   • Hydrologic System Management
   • Hydrologic Engineering Center's Hydrologic Modeling System
   • High-Efficiency Control Hydrology Model

   Hint

   Remember the engineering aspect of the acronym.

4. 4.

   True or False: GIS can be used to visualize water flow patterns.

   • True
   • False

   Hint

   Think about how maps display information.

5. 5.

   Design a simple hydrological model for a small urban area using GIS data. What considerations would you take into account when determining where to place check dams?

   Hint

   Think about the topography and current water flow.

6. 6.

   Using given GIS data, identify potential flood zones in a watershed. How would you approach mapping these areas?

   Hint

   Consider how water collects in certain low-lying areas.
