Quantifying and characterizing groundwater recharge are critical for water resources management. Unfortunately, low recharge rates are difficult to resolve in dry environments, where groundwater is often most important. ...

The sustainable development of our nation's roadway system requires quantitative means to link infrastructure performance to lifecycle energy use and greenhouse gas (GHG) emissions. Beside surface texture and roughness-induced ...

Modern engineering problems often require accurate, reliable, and efficient evaluation of quantities of interest, evaluation of which demands the solution of a partial differential equation. We present in this thesis a ...

Efficient exploitation of subsurface resources requires better understanding of subsurface physical properties as well as optimization of control strategies. Advances in technology have created the possibility of providing ...

Large earthquakes near densely populated areas such as the 1994 Northridge and 1995 Kobe events have caused extensive damage to the physical infrastructure and losses to the regional and national economies. Economic losses ...
