Spatially distributed snow depth and snow duration data were collected over two to four snow seasons during water years 2011-2014 in experimental forest plots within the Cedar River Municipal Watershed, 50 km east of Seattle, Washington, USA. These 40 m × 40 m forest plots, situated on the western slope of the Cascade Range, ...

We introduce a quality controlled observational atmospheric, snow, and soil data set from Snoqualmie Pass, Washington, U.S.A., to enable testing of hydrometeorological and snow process representations within a rain-snow transitional climate where existing observations are sparse and limited. Continuous meteorological forcing ...

This research proposes technical performance over time as a fourth pillar of sustainability theory for infrastructure. It also describes a method that allows us to discover how changes in the technical pillar (operationalised as reduced breakage rates) may moderate the influence of the social pillar (operationalised as repair ...

Paper abstract: We present results from laboratory experiments in a wave flume with and without a sediment bed to investigate the turbulent structure and sediment dynamics of wave-supported mud layers. The presence of sediment on the bed significantly alters the structure of the wave boundary layer relative to that observed ...

Case study research often claims culturevariously definedimpacts infrastructure development. I test this claim using Hofstede’s cultural dimensions and newly available data representing change in national coverage of sewer connections, sewerage treatment, and onsite sanitation between 1990 and 2010 for 21 developing nations. ...

Onsite sanitation systems experience a high failure rate with resulting environmental and public health implications. In the USA alone, the EPA estimates that 10% of the 26 million homes served by onsite systems have failed. If this failure rate is extrapolated to the 8% of the global population that the UN estimates have ...

While the construction of sanitation infrastructure is one of humankind’s greatest public health and environmental engineering achievements, its benefits are not yet enjoyed by all. In addition to the billions of people not yet reached by sanitation infrastructure, at least half of systems constructed in developing contexts ...

The "Strategic Plan" of the Alaska Department of Transportation & Public Facilities (DOT&PF) establishes "Excellence" as one of the department's core values, and defines it as "Personal and department commitment to continually improve individual, team, and organizational knowledge, performance, and methods to provide quality ...

MAP-21 establishes national objectives to increase productivity and economic efficiency of the nation’s freight infrastructure. The recent passage of MAP-21 has placed an emphasis on integrating asset and performance management tools to help transportation agencies better manage the critical transportation infrastructure. ...

This research compiled information on past landslides, including date-referencing and geo-locating events; analyzed and mapped variables contributing to slide susceptibility; demonstrated the conditions of the future climate models that may increase landslide hazards; and designated the transportation routes most vulnerable ...
