We are certain that the Earth's climate is changing because of the trends that we see in the instrumented climate record and the changes that have been observed in physical and biological systems.  The instrumental record of climate change is der
Land use change is perhaps the most observable of all environmental changes.
Climate variability (dry cycles to wet cycles) and land-use change play a large role, but there is a large amount of uncertainty around the flood quantile estimates (the value of discharge corresponding to the 100-year flood), particularly if
It comes down to a number of factors, including the pattern of movement of the rain storm in each particular watershed,  the conditions of the soil and plant matter on the ground in the watershed, and the timing of rain storm in one watershed
With increasing global surface temperatures the possibility of more droughts and increased intensity of storms will likely occur. As more water vapor is evaporated into the atmosphere it becomes fuel for more powerful storms to develop.
Land-use change is one type of human activity that is causing changes in Earth’s climate.
Following Hurricane Sandy, the USGS developed a science plan to support recovery, restoration and rebuilding efforts.
USGS research has shown no linkage between flooding (either increases or decreases) and the increase in greenhouse gases.
The provisional peak flood flow that USGS measured for the Congaree River in Columbia during the October 2015 floods was 185,000 cubic feet per second (cfs) on Sunday, October 4, 2015.
