Perhaps you should try some spelling variations:
"great increased river sediments" » "great increases river sediments", "greatly increased river sediments", "great encrease river sediments", "great increased liver sediments", "great increases driver sediments", "great increase diver sediments", "great increased marine sediments", "great increased recent sediments"
"great increased over sediments" » "great increases over sediments", "greatly increased over sediments", "great encrease over sediments", "great increased bone sediments", "great increased cancer sediments", "great increased oxygen sediments", "great increased cover sediments", "great increased over sedimentary", "great increased water sediments"
"great increase rate sediments" » "great increase water sediments", "great increase dated sediments", "great increase lake sediments", "great decrease rate sediments", "great increase data sediments"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("great increase rate sediments") OR ((("great increased river sediments") OR ("great increased over sediments")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"great increase rate sediments\") or (((\"great increased river sediments\") OR (\"great increased over sediments\"))))".
• Removing quotes may allow a broader search: (( great increase rate sediments ) or ((( great increased river sediments ) OR ( great increased over sediments )))).
• Adding a wildcard symbol may retrieve word variants: (("great increase rate sediments") or ((("great increased river sediments") OR ("great increased over sediments"))))*.
