Segun los valores obtenidos por el modelo numerico, la relacion H/[H.sub.D]=1,33 en terminos de presion relativa sobre la gola en x=-0,17[H.sub.D] indica un valor critico para la cavitacion de hp=-0,18[H.sub.D], lo que concuerda con lo indicado por la USBR
, estableciendo que una carga hidraulica mas alta que la del diseno, la trayectoria de la lamina de agua sera mas alta en la cresta, creando presiones negativas, resultando en el aumento de la descarga.
The CAP is defined to include a 336-mile aqueduct, the New Waddell Dam, modified Roosevelt Dam and the USBR
's 24.3% share, or 547 megawatts (MW), of the Navajo Generating Station (NGS).

The findings of the present study show that the vertical cut off was more effective as compared with horizontal impervious blanket in case of layered foundation being in line with the findings of various researcher (USBR
, 1987; Rezk and Senoon, 2012; Rezk and Nasr, 1991).

California's water market got a jump-start with the prolonged drought of the late 1980s and early 1990s, when the state's Department of Water Resources (CDWR) and the federal Bureau of Reclamation (USBR
) initiated a series of dry-year purchase programs, including water banks to facilitate trades among water users.
