<span style="margin:0px">Abstract: Preferential flow along common subsurface paths such as wormholes and fractures moves water through the unsaturated zone faster and more directly than diffuse or capillary flow through the bulk of soil matrix material. In
ecosystems preferential flow is vital for the efficient distribution of water through the root zone for the optimal use of plants. Field experiments in a restored tropical dryland forest in Hawaii demonstrate that the plants themselves, through their ordinary
growth and decay processes, can modify the soil over several years to enhance the preferential flow that is beneficial to them. At near-surface hazardous waste sites, minimization of preferential flow is important for contaminant containment. Field experiments
at a simulated waste trench in Idaho show that common landfill construction practices can effectively destroy macropore preferential flowpaths, though additional effects such as destruction of flow-inhibiting natural layer boundaries may offset the beneficial
effects of macropore destruction. Ongoing research on the processes of preferential flow has produced significant insights in recent decades. A major current need is for predictive methods to incorporate the improved understanding that has been achieved.<span style="margin:0px"><br>

at the USGS from 1981 to 2020. During most of his USGS career, he was Chief of the Unsaturated Flow Processes Project. His research primarily pursues process understanding and estimation methods for fundamental unsaturated-zone flow processes, with particular
emphasis on preferential flow. This work is directed toward applications in water-resource assessment, subsurface contaminant fluxes and vulnerabilities, and soil-water dynamics of natural and altered ecosystems. He pursues these largely through mathematical
modeling and development of theory, and additionally in collaborations involving field and lab experiments. He writes review articles and basic reference materials that draw on his knowledge and experience gained during more than four decades of research on
unsaturated flow<span style="margin:0px"> </span></span><span style="margin:0px;font-size:11pt;font-family:Calibri, sans-serif;color:black">(</span><span style="margin:0px;color:black"><a href="mailto:jrnimmo@usgs.gov" target="_blank" rel="noopener noreferrer" data-auth="NotApplicable" data-linkindex="1" style="margin:0px;color:rgb(5, 99, 193);text-decoration:underline"><span style="margin:0px;font-size:11pt;font-family:Calibri, sans-serif">jrnimmo@usgs.gov</span></a></span><span style="margin:0px;font-size:11pt;font-family:Calibri, sans-serif;color:black">)</span><span style="margin:0px;font-size:11pt;font-family:Calibri, sans-serif"><span style="margin:0px"></span></span></p>
