Little is known about the hydraulic fracturing of soil, although the technique holds potential for several environmental engineering applications. The dissertation research consists of laboratory experiments, where hydraulic fractures were created by injecting dyed glycerin into colluvium contained in a triaxial pressure cell, and a field test, where hydraulic fractures were created by injecting guar gum gel at shallow depths in glacial drift. The laboratory tests showed that hydraulic fractures are readily created in clayey-silt colluvium. Furthermore, hydraulic fractures created in soil with positive pore pressure were filled with two fluids: one injected to create the fracture, and pore fluid that infiltrates into the fracture tip. The length of the infiltrated tip increases with increasing fracture length.
Produced almost entirely at Experimental Television Center (ETC), the video uses a simple animation of a rotating rectangle (produced in Deluxe Paint on the Amiga Computer) as a stencil into which are keyed various versions of a processed live image of the river outside the window at ETC. This was my second attempt at a multi channel piece. The four programs have been shown in grid’s of twelve and sixteen monitors. While relatively simple in structure and shown only three times, this remains a personal favorite.
My reaction to the Gulf War and the continuing transformation of war coverage into media spectacle. Edited at PPG and an early exploration of the Ampex ADO-1000 Digital Video Effects unit.
A meditation on pollution. Based on treatments of footage I produced and shot for the Los Alamos National Labs on the subject of Radioactive Waste Water Treatment.
