In other areas where dead boxes were not feasible, severe wear of liners was experienced. Where large vertical drops existed, material friction resulted in excessive heat generation.

EXAMPLE: If a road culvert is to last 25 years with a 40% chance of failure during the design life, it should be designed for a 49-year peak flow event (i.e., 49-year recurrence interval). When streamflow records are not available, peak discharge can be estimated by the "rational" method or formula and is recommended for use on channels draining less than 80 hectares …

Chute design has improved in recent years through the use of Discrete Element Method (DEM) modeling programs, but many chutes are still drafted rather than designed. However, if the properties of the bulk solid are not properly identified, the DEM results can be worse than using the old "rule of thumb" design methods.

No Rest for the Weary: Children in the Coal Mines. For early twentieth-century Progressive reformers committed to social justice, widespread child labor—especially in coal mines, textile mills, and department stores—was particularly disturbing.
