Understand Ephemeral Gully Mechanics and Develop Large Scale Decision Support Systems for Improved Watershed Management

非点源污染，特别是农田的泥沙和磷径流，正在严重损害世界各地的几个水体。近十年来，伊利湖(五大湖之一)受到严重威胁，因为有害污染物水平增加，特别是与沉积物结合的磷。2011年，伊利湖磷诱导的藻类水华非常高，2015年夏天出现了100年来最大的藻类水华。这种退化预计将随着持续的人为气候和

Non-point source pollution especially sediment and phosphorus runoff from agricultural fields are severely impairing several water bodies across the world. In the recent decade, Lake Erie (one of the Great Lakes) is under serious threat due to increased levels of harmful pollutants especially sediment-bound phosphorus. In 2011, the phosphorus-induced algae blooms in Lake Erie were exceedingly high and the summer of 2015 produced the largest algae bloom in 100 years. This degradation is projected to worsen with continued anthropogenic climate and
