Perhaps you should try some spelling variations:
"great increase dated sediments" » "great increase dated sediment", "great increase water sediments", "great increase related sediments", "great increase data sediments", "great increase based sediments"
"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 increased over sediments", "great increased marine sediments", "great increased recent sediments"
"great increase rate sediments" » "great increase water sediments", "great increase lake sediments", "great increase cave 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 increase dated sediments"))) OR ("great increased river sediments")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"great increase rate sediments\") OR (\"great increase dated sediments\"))) or (\"great increased river sediments\"))".
• Removing quotes may allow a broader search: (((( great increase rate sediments ) OR ( great increase dated sediments ))) or ( great increased river sediments )).
• Adding a wildcard symbol may retrieve word variants: (((("great increase rate sediments") OR ("great increase dated sediments"))) or ("great increased river sediments"))*.
