relief wells are used extensively to relieve excess hydrostatic pressure in pervious foundation strata overlain by impervious top strata, conditions which often exist landward of levees and downstream of dams and hydraulic structures. placing well outlets in below-surface trenches or collector pipes helps dry up seepage areas downstream of levees and dams. relief wells are often used in combina...

In spite of the fact that the effect of earthquake on earth dams has been widely studied during the past decades, the complicated behavior of such earth structures against different seismological characteristics is still unknown. Such ambiguities necessitate more accurate studies using more comprehensive computation tools to achieve new results describing the behavior of such structures subject...

Using a new dataset, this paper presents new evidence on inequality in Latin America for the 19th century and studies the effects of factor endowments and trade on inequality. Recent research has highlighted the link between the colonial origins of inequality and its persistence in Latin America. We find that inequality varied substantially throughout the century a...

A general method for homogenization of the electromagnetic properties of a heterogeneous periodic medium is developed, based on its microstructure. This method is inspired by micromechanics (Nemat-Nasser and Hori, 1999). Contrary to other conventional techniques, commonly used in electromagnetism to calculate the overall properties of composites, this microstructurally-based method does not req...
