Soils That Are Sediments
98 Geotechnical Engineering

4.16. Where would you prospect for sources of coarse aggregate in Fig. 4.9?
4.17. An association of property owners around a small artificial lake has come
to the conclusion that the lake is filling with sediment. What are some
options?
4.18. How can extension of a river delta lead to more flooding upstream?
4.19. How does a dam contribute to erosion by a river downstream from the
dam? To the reduction of the river delta?
4.20. Why and at what depth do waves break?
4.21. In the open sea a tsunami has a very long wavelength and is barely
noticeable. Why is it so devastating when it reaches land?
4.22. Install the free version of Google Earth on your computer.
(a) Go the Grand Canyon, tilt the image, and see if there is evidence for
sedimentary rock layers overlying an igneous rock complex.
(b) Zoom in on your area and browse for some of the features listed in
Problem 4.3.
(c) Check out Greenland for evidence of global warming.
(d) Find a mountain range that has the appearance of having been eroded
by streams. What mountains are constructive?
(e) It may be a small world but it’s complicated. Play.
