Sentence examples for Necessary rainfall from inspiring English sources

Rainfall requirements depend upon the frequency and distribution of rain and the degree of water retention by the soil; the minimum necessary rainfall is about 100 cm (39 inches) evenly distributed throughout the year, but 150 200 cm (59 79 inches) is optimal.

In addition, authors38 estimated at 59 mm the necessary spring rainfall to produce a net CO2 uptake in a semiarid shrub in Arizona, and that short rainfall pulses triggered 40% of CO2 emissions from grassland in southeastern Spain for the period 2009 201339.

Some researchers are looking at how rising salt water could contaminate underground aquifers on Long Island, and others are looking at whether alternative distribution systems like new aqueducts or water tunnels might be necessary once the rainfall pattern changes.

Comparison of the ED thresholds indicates that the cumulated amount of rainfall necessary to trigger landslides in flysch deposits is larger than in post-orogenic sediments and carbonate rocks.

The simulated weather crop index approach achieves excellent correlation between simulated and observed rainfall (necessary, for example, for modeling drought conditions) at the macroscale.
