The streambed of Eddy Creek is dry in some reaches. Its banks are steep and contain riprap and concrete headwalls. A total of 20 percent of the land in the creek's vicinity is on impervious surfaces. The creek flows through one pipe. Its size is 84 inches (210 cm). [9]

The multiple arches of the Pont du Gard, in Roman Gaul. Its lower tiers carry a road across the river, and the upper tiers support an aqueduct conduit that carried water to Nimes. Roman aqueducts were built in all parts of the Roman Empire, from Germany to Africa, and especially in the city of Rome, where they totalled over 415 kilometres (258 ...
Headwall and corrie lake Cwm Idwal. In physical geography and geology, the headwall of a glacial cirque is its highest cliff.The term has been more broadly used to describe similar geomorphic features of non-glacial origin consisting of a concave depression with convergent slopes typically of 65 percent or greater forming the upper end of a drainage valley.
Basically, an arch dam is a structure that curves upstream and the water pressure is transferred either directly to the valley sides or indirectly through concrete abutments. [11] [5] Theoretically, the ideal constant angle arch in a V-shaped valley for such an arch dam has a central angle of 133° of curvature. This theory led to the ...
Monticello is a concrete medium thick arch dam 304 ft (93 m) high from the foundations, 1,023 ft (312 m) long and 239 ft (73 m) above the riverbed. The dam is 100 ft (30 m) thick at the base, tapering to 12 ft (3.7 m) at the crest. The total volume of construction materials is 326,000 cubic yards (249,000 m 3). [3]
The multiple-arch dam consists of a number of single-arch dams with concrete buttresses as the supporting abutments, as for example the Daniel-Johnson Dam, Québec, Canada. The multiple-arch dam does not require as many buttresses as the hollow gravity type but requires a good rock foundation because the buttress loads are heavy.
