Rivers shape continental surfaces; they erode continental reliefs, transport erosion products and finally deposit them in plains. As a consequence, understanding physics of sediment transport is of fundamental importance in earth sciences. However, sediment transport occurs at the dynamical interface between fluid and granular mechanics, which makes its full understanding challenging. Over the ...

HAZARD I: Software for Fire Hazard Assessment

NIST Handbook 146, HAZARD I—Fire Hazard Assessment Method [1], represents the culmination of a long-term program aimed at placing the prediction of fire outcomes on an objective and scientific basis. In the 1970s, NIST supported Harvard University to develop numerical models that could predict the temperature in a room containing a fire. These early models were difficult to use and interpret; r...

The Evolution of HAZARD, the Fire Hazard Assessment Methodology

The United States alone spends about $700B per year on new and renovated construction. About 20% of this is to assure safety from unwanted fires, which includes the cost of insurance, to make families whole after fires and to recover from business loss. This is an enormous cost to endure every year. Combined with a growing construction market in other countries, this presents a major opportunit...

Hazard/Risk Assessment HAZARD ASSESSMENT OF TEMEPHOS APPLIED TO A SOUTHWEST FLORIDA, USA, SALT MARSH COMMUNITY

This investigation was undertaken to determine whether the mosquito larvicide temephos (applied as Abate 4-Et) created an environmental hazard for nontarget organisms in a southwest Florida salt marsh community. Field toxicity tests were performed during routine larvicide applications using larvae of salt marsh crabs (Aratus pesonii and Uca rapax) and adult Mysidopsis bahia. Laboratory toxicity...
