Common use of Rainfall Clause in Contracts

Rainfall. Precipitation, as a function of time and space, is highly variable. For example, daily precipitation records at New Orleans ▇▇▇▇▇▇▇ Airport (MSY) and the Grand Isle C-MAN (GDIL1) station, that are separated by about 80 km, show the correlation coefficient of only r 2 = 0.34 in 1999 (Figure 1-6) and appears to vary seasonally (Park, 2002). There were only five stations where precipitation measurements were made in the vicinity of Barataria Basin. For this study, however, only the precipitation record from MSY was used for the following reason. The dominant upstream regions which account for 61% of total land are best represented by MSY Figure 1-4.
