24-552: It is a division of the Utah Department of Natural Resources and is an applied scientific agency, which creates, interprets, and provides information about Utah's geological environment, resources and hazards, in order to promote safe, beneficial, and wise land usage. Its departments and programs are: Editorial Services, Geologic Hazards Program, Energy & Minerals Program, Geologic Information and Outreach Program, Geologic Mapping Program, Ground Water and Paleontology Program, and

48-413: A geologist or engineering geologist that is educated, trained and has obtained experience related to the recognition and interpretation of natural processes, the understanding of how these processes impact human made structures (and vice versa), and knowledge of methods by which to mitigate hazards resulting from adverse natural or human made conditions. The principal objective of the engineering geologist

72-428: A complex nature, such as an avalanche hitting a lake and causing a debris flow, with consequences potentially hundreds of miles away, or creating a lahar by volcanism. Marine geohazards in particular constitute a fast-growing sector of research as they involve seismic, tectonic, volcanic processes now occurring at higher frequency, and often resulting in coastal sub-marine avalanches or devastating tsunamis in some of

96-521: A large extent (e.g., tsunamis ). Sometimes the hazard is instigated by the careless location of developments or construction in which the conditions were not taken into account. Human activities, such as drilling through overpressured zones, could result in significant risk, and as such mitigation and prevention are paramount, through improved understanding of geohazards, their preconditions, causes and implications. In other cases, particularly in montane regions, natural processes can cause catalytic events of

120-700: Is crucial minimizing earth related hazards. Most engineering geologists also have graduate degrees where they have gained specialized education and training in soil mechanics , rock mechanics , geotechnics , groundwater , hydrology , and civil design. These two aspects of the engineering geologists' education provide them with a unique ability to understand and mitigate for hazards associated with earth-structure interactions. Engineering geology investigation and studies may be performed: Typical geologic hazards or other adverse conditions evaluated and mitigated by an engineering geologist include: An engineering geologist or geophysicist may be called upon to evaluate

144-458: Is the protection of life and property against damage caused by various geological conditions. The practice of engineering geology is also very closely related to the practice of geological engineering and geotechnical engineering . If there is a difference in the content of the disciplines, it mainly lies in the training or experience of the practitioner. Although the study of geology has been around for centuries, at least in its modern form,

168-485: Is the theoretical and applied science of the mechanical behaviour of rock and rock masses; it is that branch of mechanics concerned with the response of rock and rock masses to the force-fields of their physical environment. The fundamental processes are all related to the behaviour of porous media. Together, soil and rock mechanics are the basis for solving many engineering geology problems. The methods used by engineering geologists in their studies include The fieldwork

192-458: Is typically culminated in analysis of the data and the preparation of an engineering geologic report, geotechnical report or design brief, fault hazard or seismic hazard report, geophysical report, ground water resource report or hydrogeologic report. The engineering geology report can also be prepared in conjunction with a geotechnical report, but commonly provides the same geotechnical analysis and design recommendations that would be presented in

216-460: The Geological Society of America . One of the most important roles of an engineering geologist is the interpretation of landforms and earth processes to identify potential geologic and related human-made hazards that may have a great impact on civil structures and human development. The background in geology provides the engineering geologist with an understanding of how the earth works, which

240-499: The climate system . Engineering geologists Engineering geology is the application of geology to engineering study for the purpose of assuring that the geological factors regarding the location, design, construction, operation and maintenance of engineering works are recognized and accounted for. Engineering geologists provide geological and geotechnical recommendations, analysis, and design associated with human development and various types of structures. The realm of

264-435: The excavatability (i.e. rippability ) of earth (rock) materials to assess the need for pre- blasting during earthwork construction, as well as associated impacts due to vibration during blasting on projects. Soil mechanics is a discipline that applies principles of engineering mechanics, e.g. kinematics, dynamics, fluid mechanics , and mechanics of material, to predict the mechanical behaviour of soils. Rock mechanics

288-684: The Hoover Dam and a multitude of other engineering projects. The first American engineering geology textbook was written in 1914 by Ries and Watson. In 1921 Reginald W. Brock , the first Dean of Applied Science at the University of British Columbia , started the first undergraduate and graduate degree programs in Geological Engineering, noting that students with an engineering foundation made first-class practising geologists. In 1925, Karl Terzaghi , an Austrian trained engineer and geologist, published

312-565: The State Energy Program. The UGS has worked on countless projects in the state, including statewide geologic hazards maps, oil shale assessment, Great Salt Lake studies, fault trenching, and the Snake Valley /West Desert Groundwater Monitoring Well Project. In addition, recent research and general geologic information is given in teacher-friendly formats for anyone to use. The "University Geological and Resource Survey of Utah"

336-692: The State School of Mines and Mineral Industries at the University of Utah . Crawford was appointed first Director of the UGMS and the Legislature appropriated $ 25,000 for the 1949–1951 biennial budget. From 1961 to 1965 the UGMS and University of Utah College of Mines and Mineral Industries jointly published the four-part, 1:250,000-scale geologic map of Utah. The first issue of the quarterly publication Quarterly Review (renamed Survey Notes in 1976), containing information pertaining to Utah's geology and mineral industry,

360-889: The Survey with responsibility for assessing earthquake risks throughout the state. The UGMS name was shortened again to "Utah Geological Survey" in 1991. In 1996 the UGS moved to the new Utah Department of Natural Resources complex and opened its regional office in Cedar City. Geologic hazards A geologic hazard or geohazard is an adverse geologic condition capable of causing widespread damage or loss of property and life. These hazards are geological and environmental conditions and involve long-term or short-term geological processes. Geohazards can be relatively small features, but they can also attain huge dimensions (e.g., submarine or surface landslide ) and affect local and regional socio-economics to

384-583: The effects of such hazards and developing plans to implement these measures. Mitigation can include a variety of measures: Eleven distinct flood basalt episodes occurred in the past 250 million years, resulting in large volcanic provinces , creating lava plateaus and mountain ranges on Earth. Large igneous provinces have been connected to five mass extinction events. The timing of six out of eleven known provinces coincide with periods of global warming and marine anoxia /dysoxia. Thus, suggesting that volcanic CO 2 emissions can force an important effect on

408-740: The engineering geologist is essentially in the area of earth-structure interactions, or investigation of how the earth or earth processes impact human made structures and human activities. Engineering geology studies may be performed during the planning, environmental impact analysis, civil or structural engineering design, value engineering and construction phases of public and private works projects, and during post-construction and forensic phases of projects. Works completed by engineering geologists include; geologic hazards assessment, geotechnical , material properties, landslide and slope stability, erosion , flooding , dewatering , and seismic investigations, etc. Engineering geology studies are performed by

432-642: The failure of the St. Francis Dam in California and the death of 426 people. More engineering failures that occurred the following years also prompted the requirement for engineering geologists to work on large engineering projects. In 1951, one of the earliest definitions of the "Engineering geologist" or "Professional Engineering Geologist" was provided by the Executive Committee of the Division on Engineering Geology of

456-579: The first text in Soil Mechanics (in German). Terzaghi is known as the parent of soil mechanics, but also had a great interest in geology; Terzaghi considered soil mechanics to be a sub-discipline of engineering geology. In 1929, Terzaghi, along with Redlich and Kampe, published their own Engineering Geology text (also in German).Engineering geology are the different types of rocks. The need for geologist on engineering works gained worldwide attention in 1928 with

480-703: The most densely populated areas of the world Such impacts on vulnerable coastal populations, coastal infrastructures, offshore exploration platforms, obviously call for a higher level of preparedness and mitigation. Sudden phenomena include: Gradual or slow phenomena include: Geologic hazards are typically evaluated by engineering geologists who are educated and trained in interpretation of landforms and earth process, earth-structure interaction, and in geologic hazard mitigation. The engineering geologist provides recommendations and designs to mitigate for geologic hazards. Trained hazard mitigation planners also assist local communities to identify strategies for mitigating

504-461: The next few years, Buranek and other contract personnel publish 36 geologic publications sponsored by the UPID. During 1946 the governor appointed Arthur L. Crawford as commissioner of the UPID and urged Crawford to activate the UGMS. Crawford re-hired Buranek and added other geologists, but work continued under the auspices of the UPID. UPID was disbanded by the state in 1949 and the UGMS was transferred to

528-444: The science and practice of engineering geology only commenced as a recognized discipline until the late 19th and early 20th centuries. The first book titled Engineering Geology was published in 1880 by William Penning. In the early 20th century Charles Peter Berkey , an American trained geologist who was considered the first American engineering geologist , worked on several water-supply projects for New York City, then later worked on

552-527: Was founded in 1919, but without funding. In 1931 the "Utah Geological and Mineralogical Survey" was created by the Utah State Legislature . The state governor appointed an advisory board, but no funding was appropriated for salaries or operations and no personnel were assigned to the Survey. In 1941 the UGMS was placed in the newly created "Utah State Department of Publicity and Industrial Development" (UPID). The UPID hired geologist A.M. Buranek. Over

576-711: Was published in 1964. In 1973 the Legislature transferred the UGMS from the University of Utah to the Utah Department of Natural Resources and officially named the Survey Director as the State Geologist. The Survey's name was also shortened to "Utah Geological and Mineral Survey" (previously "Mineralogical"). In 1977, when it created the Utah Seismic Safety Advisory Council , the Legislature charged
