FMA Challenge 3

Introduction

If you haven't already completed FMA Challenge 2, please see this FMA Challenge 2 page. This page is for TUFLOW users of intermediate to advanced ability.

In this challenge, a typical non-urban stream of the California Central Valley will be explored. The stream originates near the Sierra Nevada Foothills and conveys runoff to the West into the Central Valley Flood Management System. The streams are natural, with large amounts of conveyance in their upper reaches. As the streams progress downstream, their conveyance capacity gradually reduces. At some point nearing the valley floor, typical levees have been constructed to contain normal floods within the conveyance systems.

From this challenge, it is expected the user will develop their skills in:

• Understanding of the influence of levees on flood behaviour;
• Understanding of the influence of infiltration on flood behaviour;
• Nested 1D/2D models; and
• Understanding the Green and Ampt infiltration method and USDR soil types.
  
  

Data for this model is provided via external hard drive or DVD.
