This highlights the need to critically evaluate causes of flooding including those related to hydrology of watersheds and increased runoff rates from drainage catchments, and related to hydraulic capacity of infrastructure systems including temporary construction conditions or other operational constraints.

Some upgrading of the poor quality infrastructure was undertaken, and some heavy mineral flows passed on the line, continuing as late as 1960, but the severe operational constraints of the line led to diversion away to other routes in 1964.

Warner wrote that the missing postmarks were the " duty not of the voter but of the military postal clerk, " adding that " human error, as well as time and operational constraints, results in some mail not being postmarked ."

If the wiring is secret, the total number of possible configurations has been calculated to be around 3 x 10 114 ( approximately 380 bits ); with known wiring and other operational constraints, this is reduced to around 10 23 ( 76 bits ).

The B-36 would undergo a redesign for a four-wheel main gear bogie with tires to reduce this operational constraint and allow B-36s to operate from runways able to support Boeing B-29 Superfortresses . ( The other two runways were at the Convair plant at Fort Worth, Texas, and at Fairfield-Suisun Field, California .)
