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 increased over sediments", "great increased recent 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"great increase rate sediments\") OR (\"great increased river sediments\"))".
• Removing quotes may allow a broader search: (( great increase rate sediments ) OR ( great increased river sediments )).
• Adding a wildcard symbol may retrieve word variants: (("great increase rate sediments") OR ("great increased river sediments"))*.
