The largest contributor to&amp;nbsp;&lt;/span&gt;&lt;i&gt;a&lt;/i&gt;&lt;sub&gt;i&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;was the interfacial area in the water-filled corners of chambers and tubes containing NAPL. When&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;K&lt;/i&gt;&lt;sub&gt;diss&lt;/sub&gt;&lt;i&gt;a&lt;/i&gt;&lt;sub&gt;i&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;was divided by&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;a&lt;/i&gt;&lt;sub&gt;i&lt;/sub&gt;, the resulting curves of dissolution coefficient,&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;K&lt;/i&gt;&lt;sub&gt;diss&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;versus&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Pe&lt;/i&gt;′ suggested that an approximate value of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;K&lt;/i&gt;&lt;sub&gt;diss&lt;/sub&gt;&lt;span&gt;&amp;nbsp;could be obtained as a weak function of&amp;nbsp;hysteresis&amp;nbsp;or&amp;nbsp;&lt;/span&gt;&lt;i&gt;S&lt;/i&gt;&lt;sub&gt;N&lt;/sub&gt;. Spatially and temporally variable maps of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;K&lt;/i&gt;&lt;sub&gt;diss&lt;/sub&gt;&lt;i&gt;a&lt;/i&gt;&lt;sub&gt;i&lt;/sub&gt;&lt;span&gt;&amp;nbsp;calculated using the network model were used in&amp;nbsp;field-scale&amp;nbsp;simulations of NAPL dissolution. These simulations were compared to simulations using a constant value of&amp;nbsp;&lt;/span&gt;&lt;i&gt;K&lt;/i&gt;&lt;sub&gt;diss&lt;/sub&gt;&lt;i&gt;a&lt;/i&gt;&lt;sub&gt;i&lt;/sub&gt;&lt;span&gt;&amp;nbsp;and the empirical&amp;nbsp;correlation&amp;nbsp;of Powers et al. [Water Resour. Res. 30(2) (1994b) 321]. Overall, a methodology was developed for incorporating&amp;nbsp;pore-scale&amp;nbsp;processes into field-scale&amp;nbsp;prediction&amp;nbsp;of NAPL dissolution.&lt;/span&gt;&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</dc:description>
