Project Description

• Designed for college-level geology students
• Intended for stand-alone use outside of class to
  reinforce and expand concepts
• A modular package incorporating high-level
  concepts, mathematically accurate modeling, and
  multimedia content

The Technology
6
The Technology

• CD-ROM based Director 7 Application
• greatest flexibility in multimedia presentation
• Interactive, screen-based modules
• 2-D 3-D animation, Video, Sound
• Directed linear flow with optional branching

7
The Technology

• System Requirements
• PC
• Pentium-class 16 MB RAM 800x600, 16-bit
  display Sound Card
• Mac
• PowerPC-class 16 MB RAM 800x600, 16-bit
  display Sound

8
The Technology

• Strengths
• Allows students to visualize complex
  multi-variable systems
• Provides greater interaction with models to
  enhance comprehension
• More entertaining, stimulating excitement and
  long-term retention
• More cohesive and better organized than
  traditional text offerings

9
The Technology

• Weaknesses
• Textbooks provide a great deal more raw
  information
• Not an effective substitute for classroom-based
  expert instruction
• High entry costs

The Content
11
Content Overview

• 3 Modules
• Each module presents a single idea
• Modules ask a question to be answered
• Modules progress from basic introduction to a
  computer presentation and end with user
  interaction

12
Module 1

• Concept
• How water is partitioned amongst the components
  of a watershed
• Question
• What happens to a drop of rain when it hits the
  ground?
• Key Concepts
• Hydrology, Water Cycle, partitioning,
  infiltration, storage, water table

13
Module 1

• Introduction to basic concepts of hydrology and
  watersheds
• Primarily a presentation of facts with little
  interaction
• The simplest of all 3 modules

14
Module 2

• Concept
• Defining and delineating a watershed
• Question
• How does a raindrop contribute to a watershed?
• Key Concepts
• overland flow, subsurface flow, flow direction,
  flow integration

15
Module 2

• Introduction of flow concepts
• 3 part progression
• Explanation of a watershed
• Computer draws a watershed
• User draws a watershed
• Possible computer analysis of user performance

16
Module 3

• Concept
• Time evolution of a watersheds flow
• Question
• What happens to a watersheds flow over time?
• Key Concepts
• Flow rate, residence time, stream-flow
  generation, bucket analogy, flooding

17
Module 3

• Interaction of all earlier concepts over space
  and time
• Presentation of the bucket analogy
• Presentation of mathematical formulas
• 3-D interactive simulation of flooding
• By far, the most complex of all 3 modules
