The TechnologyThe 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

The TechnologyThe Technology

Weaknesses– Textbooks provide a great deal more

raw information– Not an effective substitute for

classroom-based expert instruction– High entry costs

The ContentThe Content

Content OverviewContent Overview

3 “Modules”Each module presents a single ideaModules ask a question to be

answeredModules progress from basic

introduction to a computer presentation and end with user interaction

Module 1Module 1

Concept– How water is partitioned amongst the components of a

watershedQuestion–What happens to a drop of rain when it hits the ground?

Key Concepts– Hydrology, Water Cycle, partitioning, infiltration,

storage, water table

Module 1Module 1

Introduction to basic concepts of hydrology and watersheds

Primarily a presentation of facts with little interaction

The simplest of all 3 modules

Module 2Module 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

Module 2Module 2

Introduction of flow concepts3 part progression– Explanation of a watershed– Computer draws a watershed– User draws a watershed

Possible computer analysis of user performance

Module 3Module 3

Concept– Time evolution of a watershed’s flow

Question–What happens to a watershed’s flow

over time?Key Concepts– Flow rate, residence time, stream-flow

generation, “bucket” analogy, flooding

Module 3Module 3

Interaction of all earlier concepts over space and time

Presentation of the “bucket” analogyPresentation of mathematical formulas3-D interactive simulation of floodingBy far, the most complex of all 3

modules
