Abstract: This paper presents an analytical solution that can be used as a simplified design aid when assessing the stability of concrete gravity dams with cracks at their base under usual load conditions. The solution is based on ...

Abstract: Laboratory experiments were conducted to investigate the abiotic interactions of soybean oil (SoyOil) and chlorinated ethene (CE) nonaqueous phase liquids (NAPLs). The mixed NAPL density and interfacial tension behaved ...

Abstract: Aroclors are dense nonaqueous-phase liquids (DNAPLs) composed of polychlorinated biphenyls, which are common subsurface contaminants. Because complete remediation of Aroclor is very difficult, biostabilization may offer ...

Abstract: The biodegradation of propylene glycol (PG) and PG-based aircraft deicing fluid (ADF) at initial concentrations of

Abstract: Biological activity in zones of chemical contamination changes the pore characteristics that control the flow of water and transport of dissolved chemicals in soils. To further the understanding of these processes, column ...

Abstract: An analytical solution is proposed to model the internal uplift pressures associated with cracks in older concrete gravity dams and assess drain effectiveness. Each crack is assumed to be finite, rectangular with constant ...

Abstract: The effect of head losses in drain pipes on crack uplift and drain effectiveness has been added to the analytical solution proposed in the first of this sequence of papers. Although drainage wells are effective in reducing ...

Abstract: Subsurface spills of high-molecular weight, multicomponent, dense nonaqueous-phase liquids (DNAPLs) are intractable for remediation by conventional techniques. This paper introduces the concept of biostabilization of the ...
