Question: James Scott caused the worst American flooding disaster since when?
Context: The 1960 Atlantic hurricane season was the least active season since 1952.  The season officially began on June 15, and lasted until November 15.  These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin.  The first system, an unnamed storm, developed in the Bay of Campeche on June 22.  It brought severe local flooding to southeastern Texas and was considered the worst disaster in some towns since a hurricane in 1945.  The unnamed storm moved across the United States for almost a week before dissipating on June 29.  In July, Hurricane Abby resulted in minor damage in the Leeward Islands, before impacting a few Central American counties — the remnants of the storm would go on to form Hurricane Celeste in the East Pacific.  Later that month, Tropical Storm Brenda caused flooding across much of the East Coast of the United States.  The next storm, Hurricane Cleo, caused no known impact, despite its close proximity to land. Tropical Storm Amelia was a weak, poorly organized tropical storm that formed during the 1978 Atlantic hurricane season.  Amelia developed from a tropical wave that moved through the Atlantic Ocean uneventfully.  The disturbance then entered an area of the Gulf of Mexico that was conducive to tropical cyclogenesis and became the first tropical depression of the season, after which it was forecast to make landfall before any significant intensification.  However, the tropical depression defied predictions, quickly strengthening into a weak tropical storm just hours before making landfall in Corpus Christi.  The storm lasted roughly a day over land before becoming unidentifiable after being active for just under 48 hours.  After dissipating, the storm caused a severe flooding disaster in Texas. Severe flooding occurred during the 2011 monsoon season in Thailand.  The flooding began at the end of July triggered by the landfall of Tropical Storm Nock-ten.  These floods soon spread through the provinces of northern, northeastern, and central Thailand along the Mekong and Chao Phraya river basins.  In October floodwaters reached the mouth of the Chao Phraya and inundated parts of the capital city of Bangkok.  Flooding persisted in some areas until mid-January 2012, and resulted in a total of 815 deaths (with 3 missing) and 13.6 million people affected.  Sixty-five of Thailand's 77 provinces were declared flood disaster zones, and over 20000 sqkm of farmland was damaged.  The disaster has been described as "the worst flooding yet in terms of the amount of water and people affected." The 2013–2014 United Kingdom winter floods saw areas of the United Kingdom inundated following severe storms.  The south of England saw heavy rainfalls associated with these storms which caused widespread flooding, power cuts and major disruptions to transport.  Economically the worst affected areas were Somerset, Devon, Dorset and Cornwall in the south west and the Thames Valley in the south east.  The Met Office reported the storms were responsible for the wettest December to January period since 1876.  The flood phenomena ranged from coastal flooding, pluvial flooding, fluvial flooding to groundwater flooding.  The flooding resulted in the inundation of the majority of the Somerset Levels and saw the main railway line to Cornwall and West Devon at Dawlish severed for several weeks. Tropical Storm Alberto was the costliest storm of the 1994 Atlantic hurricane season.  The storm was the first named storm of the season.  It hit Florida across the Southeast United States in July, causing a massive flooding disaster while stalling over Georgia and Alabama.  Alberto caused $1 billion in damage (1994 USD) and 30 deaths. In June 2013, a multi-day cloudburst centered on the North Indian state of Uttarakhand caused devastating floods and landslides becoming the country's worst natural disaster since the 2004 tsunami.  The reason the floods occurred was that the rainfall received was on a larger scale than the regular rainfall the state usually received .  The debris blocked up the rivers, causing major overflow.  The main day of the flood is said to be on 16 June 2013.  Though some parts of Himachal Pradesh, Haryana, Delhi and Uttar Pradesh in India experienced the heavy rainfall, some regions of Western Nepal, and some parts of Western Tibet also experienced heavy rainfall, over 89% of the casualties occurred in Uttarakhand.  s of 16 2013 , according to figures provided by the Uttarakhand government, more than 5,700 people were "presumed dead."  This total included 934 local residents. The history of flooding in Canada includes floods caused by snowmelt runoff or freshet flooding, storm-rainfall and "flash flooding", ice jams during ice formation and spring break-up, natural dams, coastal flooding on ocean or lake coasts from storm surges, hurricanes and tsunamis. Urban flooding can be caused by stormwater runoff, riverine flooding and structural failure when engineered flood management structures, including dams and levees, prove inadequate to manage the quantities and force of flood waters.  Floods can also occur when groundwater levels rise entering buildings cracks in foundation, floors and basements. .  Flooding is part of the natural environmental process.  Flooding along large river systems is more frequent in spring where peak flows are often governed by runoff volume due to rainfall and snowmelt, but can take place in summer with flash floods in urban systems that respond to short-duration, heavy rainfall.  Flooding due to hurricanes, or downgraded severe storms, is a concern from August to October when tropical storms can affect Eastern North America.  Flood events have had a significant effect on various regions of the country.  Flooding is the costliest natural disaster for Canadians.  Most home insurance claims in Canada deal with water damage due to sewer back-up, not fire. James Robert "Jimmy" Scott (born November 20, 1969) was convicted of causing a massive flood of the Mississippi River at West Quincy, Missouri as part of the Great Flood of 1993.  He is currently serving a sentence of 20 years to life in a Missouri prison. The K-152 "Nerpa" accident was an incident that occurred aboard the Russian submarine K-152 "Nerpa" on 8 November 2008, which resulted in the deaths of 20 people and injuries to 41 more.  The deaths and injuries were caused by an unsanctioned release of fire suppressant gas inside the submarine during a submerged test run during the vessel's sea trials in the Sea of Japan.  The gas caused victims to die of asphyxiation or suffer frostbite in their lungs.  The incident was the worst Russian submarine disaster since "Kursk" sank in 2000.  Three of the dead were military personnel and the rest were civilians from the Vostok, Zvezda, Era and Amur shipbuilding yards who were members of the acceptance team. The Great Mississippi and Missouri Rivers Flood of 1993 (or "Great Flood of 1993") occurred in the American Midwest, along the Mississippi and Missouri rivers and their tributaries, from April to October 1993.  The flood was among the most costly and devastating to ever occur in the United States, with $15 billion in damages.  The hydrographic basin affected over around 745 miles in length and 435 miles in width, totaling about 320000 mi2 .  Within this zone, the flooded area totaled around 30000 mi2 and was the worst such U.S. disaster since the Great Mississippi Flood of 1927, as measured by duration, area inundated, persons displaced, crop and property damage, and number of record river levels.  In some categories, the 1993 flood even surpassed the 1927 flood, at the time the largest flood ever recorded on the Mississippi.
Answer: 1927
