Permeability at high temperature is a very important parameter to be considered for designing underground high level nuclear waste repository (HLW) in rock mass. The surrounding rock mass is exposed to heat radiated by HLW when it is buried underground and development or extension of micro-cracks takes place in the host rock due to rise in temperature. Keeping this in view, the permeability stu...

Open-framework gravel has permeability, k, above the measurement range of most laboratory constant-head permeameters because the head difference across the length of conventional permeameters is too small to be measured. Here we addressed the challenge of measuring the high k by using a 3 m long permeameter. The head difference over this length was of the order of 10(-2) to 10(-3) m, which we c...

Experimental permeability measurements saw a considerable increase in accuracy when recommendations and guidelines were imposed upon the realization of two international benchmarks. Such requirements aid design stage experimental validation permeameter rig however, systematic errors still compromise comparability obtained by different radial rigs. Owing to hurdles limitations data acquisition s...

This study combined statistical analyses, field investigations and numerical groundwater flow modeling to quantify the connectivity between the Elkhorn River and its adjacent aquifers in Nebraska. The Mann-Kendall trend tests were conducted to detect increasing or decreasing tendencies on the time series data of streamflow, which were collected from eighteen gauging stations in the Elkhorn Rive...

Calculating water storage capacity can estimate how much rainwater infiltrates the ground. The soil infiltration and permeability test capacity. This study is to evaluate into soil. Research in Rawadanau, Serang Regency, has been conducted on relatively undisturbed land mixed agriculture at quaternary volcanic. (f) was measured using double-ring infiltrometer, (k) laboratory a permeameter. resu...
