  1. Case Study #2: Landscape Ice Road Suitability AssessmentNSDSS Workshop 4September 19-20, 2012Fairbanks & Anchorage, Alaska

  2. Motivation for the Case Study • NSDSS Workshop #3 • Held in Fairbanks, April 2011 • Attendees asked for promising case studies to demonstrate effectiveness and needs for improvement • Among the suggestions: Possibility of ice road construction off of potential permanent roads • Potential road to Umiat is good example • Key questions: • Is there water available for ice road construction? • Would cost be feasible? • Can we compare route alternatives versus each other?

  3. Basic Assessment Concept • Since we don’t know all the details, keep it simple • Plan regular spurs off of main road at regular intervals • Do basic Ice Road Planning procedure for each spur • (Sullivan 2007)

  4. Case Illustration • Hypothetical road: Dalton Hwy – Kavik Camp – Coast • ~47 mi; “Lake-rich” at ends, “Lake-poor” in middle

  5. Case Illustration • Suitability analysis: • Ice road start points at 50,000 ft spacing • Each ice road 25,000 ft long • Lakes identified along corridor

  6. Case Illustration • Tool batch processes 10 ice road routes and displays properties of lowest cost routes for each road.

  7. Case Illustration • Water haul distance changes dramatically along gravel road ~5 mi 6.3-8.4 mi 2.6-6.4 mi 2.2-3.9 mi 34-36 mi
