PDF-The origin of megaripples, long wave ripples and Hummocky Cross-Strat

et al 1983 Van de Meene et al 1996 but also on the shoreface Green and Black 1999 and in the surfzone Greenwood and Sherman 1986 Except Southard et al 1990 all references are to field studi. of wave ripples. Colleagues at. Massachusetts Institute of Technology. Taylor Perron, Justin Kao, Kim Huppert, Abby Koss, Jocelyn Fuentes, and John Southard. Ripples arise from an instability in sediment transport over bed perturbations. Avalanching + settling limit growth. Section 1: What are Waves. SWBAT: . Explain . the relationship among waves, energy and matter. Science Starter. 1. Name . 3-5 types of . waves.. 2. What . do you think creates waves on the ocean?. When you are relaxing on an air mattress in a pool and someone does a cannonball dive off the diving board, you suddenly find yourself bobbing up and down.. OR. Strategy:. Relate sedimentary characteristics of ancient deposits (grain size, . sedimentary . structures, geometry) to features observed in modern rivers.
