... in carbonate aquifer systems is not well documented. Water and sediment from cave streams within the Ozark Plateau of Missouri, USA, were collected and analyzed for E2. The persistence of E2 in the water was examined in two separate experiments, in which the holding temperatures (20°C vs. 4°C), bottle type...

.... Overpressure development in marine sediments is a major pre-conditioning factor that favours slope instability by decreasing the amount of gravitational driving stresses required to mobilize sediments ( Dugan and Sheahan 2012 ). If the pressure of the water contained in the pore space exceeds the hydrostatic...
