Transmissivity variations in mudstones.
Many people in sub-Saharan Africa have to rely on meager water resources within mudstones for their only water supply. Although mudstones have been extensively researched for their low permeability behavior, little research has been undertaken to examine their ability to provide sustainable water supplies. To investigate the factors controlling the occurrence of usable ground water in mudstone ...
متن کاملChapter 2: Deposition of Mudstones and Shales Deposition of Mudstones and Shales: Overview, Problems, and Challenges
As pointed out in the introduction to this book, shales contain the lion’s share of earth history that is recorded in sedimentary rocks. Understanding their deposition is key to the reconstruction of past oceans, landscapes, climates, and climatic cycles. Yet, whereas students of sandstones and carbonates have been able to learn a great deal about the deposition of these rocks from studying bed...
متن کاملBayesian Updating for Transmissivity Estimation in a
The majority of this course has focused on large scale climate and human health applications. The paper presented here, however, is an example of a smaller scale application of statistics to a geo-environmental issue. Researchers intend to model groundwater in an approximately 200 kilometer (km) by 300 km area around the city of Winnipeg, Manitoba, Canada. The study area is located on the easte...
متن کاملAir transmissivity of feathers
The flight feathers and their coverts of a European kestrel Falco tinnunculus have been tested for their air transmissivity. The transmissivity was measured in both directions, i.e. from ventral to dorsal and vice versa; the mean difference between the two directions was less than 10 %. However, the transmissivity of the inner versus outer vanes of the remiges and coverts differed significantly...
متن کاملLaboratory Testing of Silica Sol Grout in Coal Measure Mudstones
The effectiveness of silica sol grout on mudstones is reported in this paper. Using X-ray diffraction (XRD), the study investigates how the silica sol grout modifies mudstone mineralogy. Micropore sizes and mechanical properties of the mudstone before and after grouting with four different materials were determined with a surface area/porosity analyser and by uniaxial compression. Tests show th...
