and sharp bend. The dam is located in the Paute River, Ecuador. The river
topography and triangulation data is available through BreZo (Sanders and
Begnudelli, 2010). The computational domain with 74224 elements and ini-
tial water depth contours are shown in Figure8.35 (units in meters). The
dam is considered as a straight line between (x, y) coordinates of (739602 m,
9684690 m) and (739616 m, 9684530 m), separating the upstream and down-
stream region. Initial water level upstream of the dam is 2362 m above sea
level and the downstream channel is dry. A Manning roughnes ...
