Abstract:
Abstract. We present a model computing damage costs from drought-induced soil subsidence related to shrinking and swelling soils. The model uses an indicator applicable across different climate regimes. The influence of geology and land use on regional damage levels is taken into account. Simulation results are evaluated at departmental scale, showing a good representation of the regions affected by drought-induced soil subsidence. Substantial differences between simulated and observed damages are however found in some departments.

Tillage operations in farming often require high traction forces applied by tractor wheels. These interact with topsoil via a stress system along the contact surface, this interaction resulting in soil and tyre deformation. Topsoil is subject to normal and tangential stresses at the contact surface. The tangential stress rises sharply with increasing traction force and may cause topsoil among tyre lugs to fail, with the consequent formation of a strengthless layer strongly exposed to erosion and an underlying layer where shear deformations contribute to the alteration of soil structure functio

Abstract:
Abstract Dry storage systems (DSSs) store spent nuclear fuel at many operating and decommissioned power reactor sites in the United States. Overpacks and support pads include various structural subcomponents that are constructed of concrete and reinforcing steel. These concrete components are commonly exposed to outdoor air and groundwater or soil environments in which the materials may be susceptible to degradation. Potential environmental, thermal, mechanical, and irradiation-induced aging mechanisms include freeze and thaw, creep, reaction with aggregates, aggressive chemical attack, corros

Abstract:
Abstract Severe corrosion and mechanical damage are studied in the largest Mexican bridge over seawater. The bridge has been in service since 1982 in marine tropical environments of the Gulf of Mexico. The bridge is supported by sets of long piles, about 20m length and a cross section of 45cm x 45cm, which were hammered down into sea soil. The concrete of the piles exhibits cracks up to 4m length above sea level. Half cell potential and electrical resistivity measurements indicated that large portions of the piles are in favorable conditions for high corrosion activity of rebar. Chloride penet

Abstract:
Abstract As part of a pipeline integrity management (PIM) assessment of the Riviera Park line north of Amarillo, Texas, we were performing an internal corrosion direct assessment (ICDA) dig to determine if internal corrosion was present due to this location being identified as a critical angle.1, 2. A critical angle is an area that could be a possible water hold up region. The pipe being examined was immediately upstream of a suspended creek crossing, and MIC was discovered on the external surface of the east leg of the crossing.

Abstract:
Two Transport Rotorcraft Airframe Crash Testbed (TRACT) full-scale tests were performed at NASA Langley Research Center's Landing and Impact Research Facility in 2013 and 2014. Two CH-46E airframes were impacted at 33-ft/s forward and 25-ft/s vertical combined velocities onto soft soil, which represents a severe, but potentially survivable impact scenario. TRACT 1 provided a baseline set of responses, while TRACT 2 included retrofits with composite subfloors and other crash system improvements based on TRACT 1. For TRACT 2, a total of 18 unique experiments were conducted to evaluate ATD respon

Abstract:
Failures in transmission pipelines are often the result of mechanical damage. The US DOT has indicated that 20 to 40 percent of the serious pipeline incidents in any given year are related to mechanical damage. This damage is due to third party activities, mishandling during construction, pipeline bedding material consolidation, or ground movement.

Abstract:
This project was completed to support the development of a guidance note for the disposition of welds interacting with pipe wall mechanical damage (dents, wrinkles, and ovality) and thus allow a more rational treatment of these forms of damage. The intent is not to evaluate the life of welds interacting with dents wrinkles and ovality, but rather to identify when the interaction is significant and needs to be considered explicitly. Based upon the criteria developed in this project, inspection results that indicate the presence of pipe wall deformation in the vicinity of a girth weld or long se

Abstract:
With the growing emphasis on extending the useful operation of existing pipelines and reducing the operating costs, the pipeline industry is sensitive to keeping pipelines in service and having a rational basis for doing so. When pipelines undergo fault displacement, mining subsidence, thaw settlement, or landslide induced soil loading, monitoring of pipeline strains and/or displacements must protect their integrity. Currently, there is little information available to indicate when remedial action is necessary for such a pipeline. This report focuses on assisting pipe-monitoring programs by pr

Abstract:
Wetlands at Florissant Fossil Beds National Monument (FLFO) are important because they are biodiversity hotspots and support iconic wildlife. They also provide valuable ?ecosystem services? such as attenuating floods, storing water, recharging aquifers, stabilizing and sequestering sediment, storing carbon, enhancing water quality, and cycling nutrients. This report summarizes 11 years (2009?2019) of wetland monitoring in three sentinel wetland complexes in FLFO. Monitoring included annual samples of 10 wet meadow and fen wetland sites in these complexes. We partition the data into a baseline

Abstract:
In Denmark, many old buildings are constructed with massive masonry basement walls. Originally, these basements were used for storage or as boiler room. Hence moisture in the basement walls was not considered a problem, and moisture protection of basement constructions was not considered necessary. However, leaving older buildings basement walls exposed to moisture from the surrounding soil, results in a high risk for damage and mould growth on the interior surface of the exterior basement walls. Today, many of these basements are used for daily purposes. Accordingly, moisture problems in the

Abstract:
Field bends in large diameter pipe are routinely used in the construction of oil and gas pipelines. Mild ripples along the intrados are often unavoidable where such bends have a high D/t or high yield strength. Present regulations and industry standards differ in their treatment of mild ripples, ranging from silence to prohibition, depending upon interpretation. Consequently, the application of acceptance standards for such features is inconsistent, leading to variable standards of inspection and probable scrapping of otherwise sound bends.
