Viewers are provided with a short introduction to the hyporheic zone and its functions. Stream tracer techniques and electrical resistivity tomography are introduced briefly. Finally, samples of two- and three-dimensional imaging of a field experiment are presented as a proof of concept.</p> <div class="og_rss_groups"><ul class="links"><li class="first last og_links"><a href="/node/10900" class="og_links">Hydrograf(x) - 2009</a></li> </ul></div> hyporheic geophysics tomography solute Hydrograf(x) - 2009 Sun, 15 Nov 2009 15:00:30 -0800 asward358 14445 at http://www.scivee.tv
