A Tragic Dam Failure in Hawaii: The Ka Loko Dam Mary BovaConti, Sammie Merrill, Nick Vassiliadis
Step 1: Problem Statement • On March 14, 2006, the Ka Loko Dam located in Kauai, Hawaii, failed due to erosion, overtopping, an uneven crest, and lack of maintenance resulting in destroyed homes and seven deaths.
What • Where • When • Why • How
Step 3: Possible Solution Nick’s drawing Sammie’s drawing Mary’s drawing
Step 4: Select the Best Possible Solution • The dam was built from materials that came from the earth; clay, sand, soil, rock, and mud. • Use concrete instead
Step 5: Construct the Prototype Materials: • Plastic box – 2’ x 1’ (1) • Sand – 400 mL • Flour – 600 mL • Salt – 500 mL • Dirt – 500 mL • Water – 5 L • Popsicle Stick (4) • Balsa Wood – 2 ft. (4) • Measuring Cup (1) • Cups (4) • Scissors (1) Procedure 1 • Get the plastic box • 4 pieces of balsa wood and cut them • Cover them with plastic rap • Glue them to the bottom • Get the mixing materials and mix them • Dump the mix in the mold Procedure 2 • Make the mold again • Mix the grout • Poor the grout and wait for it to dry
Step 6: Test and Evaluate • Fill each cup with about 800 mL of water. • Bring them to the dam, and start pouring them into the smaller side of the box, and on top of the dam to imitate rain. • Soil, flour, dirt, and sand made dam should fail, and grout and water made dam should succeed.
Failure This is the dam that failed Earthen Clay, rocks, soil
Success This is our solution Cement
Step 7: Commutate • The solution is communicated through this written design plan (EDP) and via the group presentation on Friday, April 4 (Today).
