DredgeFest Great Lakes

An invitation: DredgeFest Great Lakes is a symposium, field expedition, and set of speculative design workshops about the human manipulation of sediments within this region. It is an encounter between government agencies, designers, theorists, academics, corporate practitioners, industry experts, students, and the public.  DredgeFest Great Lakes runs August 14-21 2015 in Minnesota. DredgeFest Great Lakes […]


DredgeFest Louisiana

Geographer Richard Campanella has evocatively described the Mississippi River—which is North America’s largest river, discharging more than three times as much water as the next largest river in the United States—as the “land-making machine”. And, indeed, historically, this is what the Mississippi River did: it made land, building its enormous delta—the southern half of the […]


Massively Redistributed in Space and Time

“If the earth were left alone [without human influence] on the order of eight cubic kilometers (10.5 billion cubic yards) of the material of the continents would be swept away by rivers into the ocean every year…By some estimates, about a third of this natural volume is prevented from reaching the oceans as a result […]

Anthropogenic Delta of Lake Mills Reservoir, Elwha River, Washington.  Above: inset model on the left shows the valley’s topography as surveyed circa 1917 before the construction of Glines Canyon Dam.  The model on the right shows topographic difference (in vertical feet) between the 1917 survey and 2010 LIDAR and Bathymetric survey data (Bureau of Reclamation), […]


Soft Systems: Bracket 2

Located in the Chesapeake Bay, Poplar Island (above) is a flagship example of the USACE’s “beneficial uses of dredge”. Working with state and federal organizations, the USACE has been placing dredged sediments from The Port of Baltimore’s shipping channels onto the island since the mid-90’s.  This practice meets the Port’s immediate need for a dredge […]


Making the Geologic Now

[Aerial view of Amwaj Island, Bahrain, where 2.79 million square meters have been reclaimed from the sea.  The foundation of these islands and its surrounding breakwaters are made of geotubes, sausage-like casings of geotextile fabric that have been pumped full of 12 million cubic meters of dredged ocean sediments recycled from navigation channels and marinas.  […]

Invitation to DredgeFest NYC

[Left: The British Headquarters Map, circa 1782, considered one of the most detailed surveys of Mannahatta’s early topography and ecology. Right: Mannahatta map illustrating the differences in the island’s elevation between 1609 and today. Grays and blacks indicate increases in elevation, mainly waterways that have been filled in, while browns indicate decreases in elevation, such […]
