In late Holocene, climate is dryer and cooler than that in middle Holocene, the precipitation of drainage area decreases. So runoff deceases, the width of riverbed becomes narrow.
進(jìn)入全新世晚期，由于氣候相對(duì)于全新世中期變得較為干燥，也較為溫涼，流域來(lái)水減少，故流量減小，河床寬度變小。

The settlers had plans to remove water from the area and in the eighteen eighties developers began digging drainage canals.

They say that the area is environmentally damaged anyway, thanks to drainage and over-grazing, and that the new wind farms would have only a minor impact.
