Introduction to Numerical Modeling

DESCRIPTION

This course presents the basic ideas and approaches of numerical modeling for water resources engineering.

Numerical models are widely used to test water resources plans and to assess the impacts of both projects and natural events on challenges such as flood and storm damage reduction, stream restoration, sediment management, and many others. A wide variety of models are available and it’s seldom obvious which model is the best choice for a given situation. Yet there is a sound engineering approach to model selection and usage that non-modelers can learn and apply without becoming computational experts.

LEARNING OBJECTIVES

Participants will:

  • Learn how models are conceived and built.
  • Understand the role of models as stories about real life.
  • Be able to describe the differences between finite difference, finite element, and finite volume; implicit vs. explicit; and steady vs. unsteady methods.
  • Learn how to select the best model for the job and spot common problems.
  • Be able to identify and use best modeling practices.

INTENDED AUDIENCE

The course will be useful to those who manage and advise water resources projects as well as beginning model users who want to learn best model practices from the beginning.

COURSE BENEFITS:

  • Learn how your business or agency can benefit from numerical modeling.
  • Help clients understand the proper use of numerical models.
  • Be able to spot time and cost problems early.
  • Earn PDH.
