CHAPTER V. _Different Types of Earth Dams._ There are several types of earth dams, which may be described as follows: 1. Homogeneous earth dams, either with or without a puddle trench. 2. Earth dams with a puddle core or puddle face. 3. Earth dams with a core wall of brick, rubble or concrete masonry. 4. New types, composite structures. 5. Rock-fill dams with earth inner slope. 6. Hydraulic-fill dams of earth and gravel. The writer proposes to give an example of each type, with such remarks upon their distinctive features and relative merits as he thinks may be instructive. Earth Dams with Puddle Core Wall or Face.
