A novel framework for uncertainty propagation in river systems based on performance graphs using two-dimensional hydrodynamic modeling

Creator:: Gifford-Miears, Christopher H.
Abstract:: This thesis presents a novel approach for propagation of uncertainty in river systems. Errors in data observations and predictions (e.g., stream inflows), in model parameters, and resulting from the discretization of continuous systems, all point to the need to accurately quantify the amount of uncertainty carried through the modeling process....

Nonlinear dynamic response of cable/lumped-body system by direct integration with suppression

Resource Type:: Masters Thesis

A numerical study of the response of Lake Kinneret to wind forcing

Creator:: Vernieres, Guillaume
Abstract:: Lake Kinneret is Israel's only fresh water lake (unless you count the Dead Sea). It spans roughly 20km from north to south, and about 12km at its widest east west extent. It is not quite 50m deep at its deepest point. In late spring, the lake stratifies significantly and remains...

A "mildly inconsistent" method for accelerating upstream corner balance transport

Creator:: Gulick, John C.
Abstract:: A new method for accelerating the Upstream Corner Balance (UCB) discretization of the equation of transfer is introduced. The inconsistent acceleration equations for the UCB discretization are derived by applying the "Modified 4-Step" diffusion synthetic acceleration technique not to the UCB discretization, but instead to the simple corner balance (SCB)...

Laboratory observations and numerical modeling of inner surf and swash zone hydrodynamics on a steep slope

Creator:: Shin, Sungwon
Abstract:: Laboratory data of free surface elevations and fluid velocities were obtained using a laser-Doppler velocimeter for the case of a periodic wave plunging over an impermeable, steep (1:10) slope with a fixed bottom roughness. The measurements were conducted over 15 cross-shore locations from the outer surf zone to the swash...

Nearshore hydrodynamic model comparisons and predictions of bathymetric evolution

Creator:: Lescinski, Jamie M.
Abstract:: The surf zone exhibits large energetic signals from wave shoaling and subsequent dissipation due to breaking, forcing circulation. The bathymetry responds to the wave and wave-induced circulation with the growth, transport, and destruction of large scale bathymetric features, such as mega ripples and sand bars. There is an obvious fluctuation...

An investigation on the modeling of wave field transformation and shoreline morphology near steep bathymetric features

Creator:: Michalsen, David R.
Abstract:: Steep bathymetric anomalies in the beach profile, such as offshore borrow pits, submerged breakwaters, and nearshore canyons can significantly transform the wave climate through the effects of refraction, diffraction, and reflection. When located in the nearshore region the modified wave climate can also substantially change the location of breaking and...

Existence of a solution to a variational data assimilation method in two-dimensional hydrodynamics

Creator:: Hagelberg, Carl R.
Abstract:: The main result of this paper is a proof of the existence of a solution generated by a method for the variational assimilation of observational data into the two-dimensional, incompressible Euler equations. The data are assumed to be given by linear (measurement) functionals acting on the space of functions representing...

Modeling shallow-water hydrodynamics : rotations, rips, and rivers

Creator:: Long, Joseph W.
Abstract:: Hydrodynamic models are used as a diagnostic tool to understand the temporal variability of shallow-water processes that are difficult to completely resolve with traditional field measurements. For all simulations, modeled quantities are qualitatively or quantitatively compared with available measurements to gain confidence in conclusions derived from the modeled results. In...
