| Title: | Conduit roughness and dye-trace breakthrough curves: why slow velocity and high dispersivity may not reflect flow in distributed systems / J.D. Gulley, and 3 others. |
| Author(s): | Gulley, J. D. |
| Date: | 2012. |
| In: | Journal of Glaciology. (2012.), Vol. 58(211) (2012) |
| Abstract: | Describes measurement of dye-trace breakthrough curves (BTCs) from persistent, mapped subglacial conduit beneath Rieperbreen, Svalbard, to test theory that BTCs that increase in velocity and decrease in dispersivity through melt season indicate switch from distributed to conduit subglacial drainage system. Results suggest slow and highly dispersed BTCs may be due to seasonal changes in conduit roughness. |
