Abstract: An experimental program was conducted to obtain data from model tests to evaluate the effects of open trenches on blast‐induced circumferential and longitudinal stresses on an underground pipeline. A model pipe was ...

Abstract: Western Kansas is underlain by the Ogallala aquifer that produces water of good quality. Many large‐capacity wells have been drilled for irrigation, industrial, and municipal use. Ground‐water withdrawals exceed recharge ...

Abstract: Assimilating hydrographic observations into a planetary geostrophic model is posed as a problem in control theory. The cost functional is the sum of weighted model and data residuals. Model errors are assumed to be spatially ...

Abstract: AbstractA new empirical model of ocean tides has been developed for the Weddell Sea, south of 66°S, between 90°W and 0°, using six years of radar altimeter data from the CryoSat-2 satellite mission. Because of its long ...

Abstract: The spatially averaged frequency spectrum of sea level has been computed at 4 cycle-per-year resolution and a Nyquist frequency of 0.5 cycles per hour using dual-satellite crossover data from the Jason and

Abstract: A near-global model for the sea surface expression of the baroclinic tide has been developed using exact-repeat mission altimetry. The methodology used differs in detail from other altimetry-based estimates of the open ...
