Landslides Grand Ditch and Poudre Pass Mosaic, Rocky Mountain National Park Colorado The image above shows part of the Grand Ditch in Rocky Mountain National Park. This ditch carries water from the Colorado River Basin across the Continental Divide and irrigates farms in northeast Colorado. The city of Thornton, located near Denver, recently purchased rights to half the water flowing through the ditch to support future city growth. The Department of the Interior asked RSR to provide aerial photography of water diversions in Rocky Mountain National Park. These photos establish a data base to record changes and direct restoration efforts in the Park. These photos were entered as evidence in a water rights trial to demonstrate effects of water diversion from federal lands. South Portion of the Grand Ditch The above mosaic show about 10 miles of the ditch corridor. The map below depicts the area covered in the mosaic. These images show a portion of the ditch that was damaged by a landslide. The image on the left was taken with a wide-angle lens, while the other image was made with a normal lens. They were used by the U.S. Departments of Interior and Agriculture in a landmark water rights trial to show the effects of water diversion. The water is carried through a culvert beneath the road visible in the photo on the right. All the images were taken from an RPV that was launched and landed on this road. The image on the left shows a failure of the Grand Ditch. The ditch is visible along the left edge of the the photo on the left. A landslide filled the ditch, causing it to fail. The water in the ditch overflowed its banks and caused the gully that goes from left to right in the image. This gully can be seen in the photo on the right, indicated by the arrow. The ditch overflow drained into the headwaters of the Colorado River, which is also visible in the right image.

Mitigation Division Fact Sheet: Landslides and Mudflows Landslide and mudflows usually strike without warning. The force of rocks, soil, or other debris moving down a slope can devastate anything in its path. Take the following steps to be ready. BEFORE Get a ground assessment of your property. Your county geologist or county planning department may have specific information on areas vulnerable to landsliding. Consult a professional geotechnical expert for opinions and advice on landslide problems and on corrective measures you can take. Minimize home hazards. Plant ground cover on slopes and build retaining walls. In mudflow areas, build channels or deflection walls to direct the flow around buildings. Remember: If you build walls to divert debris flow and the flow lands on a neighbor's property, you may be liable for damages. Learn to recognize the landslide warning signs.

INTRODUCTION MAPS '82 DAMAGES SUGG. READING The U.S. Geological Survey produced special landslide hazard maps of the San Francisco Bay Area for the California State Office of Emergency Services (OES) and the National Weather Service (NWS) Now, these maps are available on-line The USGS has experience with catastrophic events associated with the winter storms of 1982 and 1983. New USGS maps are geared to reduce the loss of life and property from storm-induced landslides and debris flows (a.k.a. mudslides). Landslide maps identify areas where the greatest threat to property exists from the movement of deep-seated landslides ( see computer simulation from 1996-97 for example ). The areas potentially subject to slope failure generally coincide with the location of previous landslides and specific geologic materials. Now, fly-by movies are available: One fly-by depicts an animation of a slow-moving bedrock landslide, from a cross-sectional view. An instructional introduction is included in the animation. The other two animations show, as red patches, areas of mapped landslides in the East Bay Hills and in Marin County. These areas are part of the 85,000 landslides that have occurred sometime in the past throughout the Bay region.

Home Practices Civil/Structural Engineering : Geotechnical, Geological and Geomechanical Engineering Geotechnical, geological, and geomechanical engineers and scientists work with large volumes of soil, rock, and fluids with properties that are poorly understood compared to the structures that they support. Failures of naturally complex soil and rock masses, and the structures built upon or within them, often occur because the initial geotechnical, geological, and geohydrological characterizations were inadequate.

18. CNN - Dozens Of People Die In China Landslides - June 6, 1996 CNN.com http://www.cnn.com/WORLD/9606/06/china.landslide/

Dozens of people die in China landslides June 6, 1996 Web posted at: 11:30 a.m. EDT (1530 GMT) YUNNAN PROVINCE, China (CNN) Two huge landslides in southwestern China killed nearly 80 people and left another 148 missing, local officials said. Rescuers who carried away bodies tied to poles continued to search Thursday for victims. The landslides, which struck a gold mining region in southwestern Yunnan province Monday and last Friday, injured 77 people, the officials said. The slides, thought to have been triggered by four days of heavy rains, devastated the Daping gold mine on Laojinshan mountain, 2,350 kilometers (1,460 miles) southwest of Beijing. The area is near North Vietnam. In English, Laojinshan means "old gold." The landslides left a gash in the earth hundreds of meters (feet) long and dozens of meters wide that stretched nearly from the mountain top to a river at its foot. Piles of earth spilled into the river, virtually blocking it. The slides reduced huts to matchwood, and buried 26 gold pits and three sheds, officials said. Four people buried in the pits were pulled out alive Tuesday, along with 16 bodies, they said. More than 1,200 people aided in the rescues.

Types and Effects Location Gas Lahars Landslides Lava Flows Pyroclastic Flows Tephra Volcano Landslides Start of landslide What are volcano landslides? Landslides are large masses of rock and soil that fall, slide, or flow very rapidly under the force of gravity. These mixtures of debris move in a wet or dry state, or both. Landslides commonly originate as massive rockslides or avalanches which disintegrate during movement into fragments ranging in size from small particles to enormous blocks hundreds of meters across. If the moving rock debris is large enough and contains a large content of water and fine material (typically, >3-5 percent of clay-sized particles), the landslide may transform into a lahar and flow downvalley more than 100 km from a volcano! Volcano landslides range in size from less than 1 km to more than 100 km . The high velocity (>100 km/hr) and great momentum of landslides allows them to run up slopes and to cross valley divides up to several hundred meters high. For example, the landslide at Mount St. Helens on May 18, 1980, had a volume of 2.5 km , reached speeds of 50-80 m/s (180-288 km/hr), and surged up and over a 400 m tall ridge located about 5 km from the volcano!

20. CNN - Landslides Claim At Least 28 In India - June 9, 1997 CNN.com http://www.cnn.com/WORLD/9706/09/india.mudslides/

Landslides claim at least 28 in India June 9, 1997 Web posted at: 11:04 a.m. EDT (1504 GMT) GANGTOK, India (CNN) Heavy rains triggered landslides in mountainous northeastern India, killing at least 28 people, authorities said Monday. At least nine landslides hit Gangtok, capital of the Himalayan state Sikkim, said police chief P.C. Sharma. One landslide swept a four-story building onto two government bungalows, crushing nine people, Sharma said. Twenty-four bodies have been recovered and at least four more were presumed dead, the chief said. The death toll may rise, he said, as rescuers search the rubble. "We are accustomed to landslides here and there," Sharma said, "but this time it's something very serious." The monsoon season, later in the year, usually brings landslides to the state. Gangtok sits at an altitude of 5,000 feet (1,525 meters), surrounded by steep slopes rising to 8,000 feet (2,440 meters). "I heard a loud noise around 9 last evening and rushed out along with my family members and took shelter on the road," survivor Shipintso Bhutia said of Sunday night's mudslide. "Seconds after, I saw the hillside tumbling down, which took away my house." Sikkim, surrounded by Tibet, Nepal and Bhutan, has been part of India since 1975, when its legislature voted to abolish its monarchy and join the Indian union.
