  • Download E-books The Physics of Blown Sand and Desert Dunes (Dover Earth Science) PDF

    By R. A. Bagnold

    An professional treatise at the starting place and evolution of dunes, this vintage paintings was once utilized by NASA in learning sand dunes on Mars and is acceptable for undergraduate and graduate scholars. the 1st ebook to deal completely with the habit of blown sand and comparable land types, its available type makes it a permanent reference greater than part a century after its preliminary publication.
    The writer studied the sands of North Africa for a few years sooner than global struggle II and is well-known as a number one authority at the topic. His three-part therapy starts together with his wind-tunnel experiments, which he carried out to enquire the mechanism of sand delivery. First, an account of the saw circulation of the person grains, via a bankruptcy at the floor wind and its dependence at the form of floor over which it blows, shape a accomplished view of the interplay among wind and sand. half considers small-scale floor phenomena, akin to ripples and ridges, and the heavily comparable topic of size-grading the grains.
    The 3rd half makes use of the foregoing effects to provide an explanation for the expansion and flow of dunes generally, and the unusual features of the 2 major dune kinds. a mode of settling on the interior constitution of amassed sand illuminates either the sand's sporting strength for motor shipping and its water-retention capability. a last bankruptcy, derived from firsthand wisdom, examines the interesting topic of "singing sand."

  • Download E-books California Earthquakes: Science, Risk, and the Politics of Hazard Mitigation (Creating the North American Landscape) PDF

    By Carl-Henry Geschwind

    In 1906, after an earthquake burnt up a lot of San Francisco, best California officers and scientists defined the catastrophe as a one-time prevalence and guaranteed the general public that it had not anything to fret approximately. California Earthquakes explains how, over the years, this angle replaced, and Californians got here to simply accept earthquakes as an important risk, in addition to to appreciate how technological know-how and expertise might decrease this threat.

    Carl-Henry Geschwind tells the tale of the small workforce of scientists and engineers who―in rigidity with actual property speculators and different pro-growth forces, deepest and public―developed the clinical and political infrastructure essential to enforce higher earthquake understanding. via their political connections, those reformers succeeded in development a kingdom equipment within which regulators may perhaps interact with scientists and engineers to lessen earthquake risks. Geschwind info the conflicts between scientists and engineers approximately how top to lessen those hazards, and he outlines the dramatic twentieth-century advances in our figuring out of earthquakes―their motives and the way we will attempt to arrange for them.

    Tracing the historical past of seismology and the increase of the regulatory country and of environmental wisdom, California Earthquakes tells how earthquake-hazard administration took place, why a few teams assisted and others fought it, and the way scientists and engineers contributed to shaping it.

  • Download E-books Carbonate Diagenesis and Porosity PDF

    Carbonate diagenesis is a topic of large complexity as a result of the easy chemical reactivity of carbonate minerals. those carbonate minerals react fast with normal waters that both dissolve the carbonates, or precipitate new carbonates to convey the water into equilibrium with the host carbonate sediments and rocks. those rock-water interactions both create porosity by way of dissolution, or damage porosity through the precipitation of carbonate cements into pore areas. Carbonate Diagenesis and Porosity examines those vital relationships intimately. This quantity is released in co-operation with OGCI, and relies on education classes organised by means of OGCI and taught by way of Dr. Moore. it's meant to provide the operating geologist and college graduate scholar an inexpensive evaluate of carbonate diagenesis and its impression at the evolution of carbonate porosity. It starts off with a dialogue of the most important transformations among carbonates and siliciclastics in order that the amateur could have an appreciation of the elemental nature of the carbonate approach. Carbonate porosity, its nature and its category is then mentioned in order that the connection among diagenesis and porosity should be validated. Environments of diagenesis and their features are defined, stressing the character of pore fluids present in every one atmosphere. instruments for the popularity of those environments are then mentioned with pressure at the constraints suffered through each one process. every one significant diagenetic surroundings is then mentioned intimately with petrographic, geochemical features defined, and a close dialogue of the impression of the environment's diagenetic strategies on porosity improvement and evolution. Diagenetic versions are built the place applicable and standards for popularity indexed. Case histories illustrating those innovations and types are provided for every significant diagenetic setting and sub-environment. Over one hundred sixty line drawings illustrate
