The model is used to derive a daily water balance for subareas in a watershed, ultimately producing simulated streamflows that can be input into routing and accounting models used to assess downstream water availability under current conditions, and to assess the sensitivity of water resources in the &lt;span class="searchword"&gt;basin&lt;/span&gt; to alterations in climate. A &lt;span class="searchword"&gt;geographic&lt;/span&gt; &lt;span class="searchword"&gt;information&lt;/span&gt; &lt;span class="searchword"&gt;system&lt;/span&gt; (&lt;span class="searchword"&gt;GIS&lt;/span&gt;) is used to automate a method for extracting physically based hydrologic response unit (HRU) distributed parameter values from &lt;span class="searchword"&gt;digital&lt;/span&gt; &lt;span class="searchword"&gt;data&lt;/span&gt; sources, and for the placement of those estimates into &lt;span class="searchword"&gt;GIS&lt;/span&gt; &lt;span class="searchword"&gt;spatial&lt;/span&gt; &lt;span class="searchword"&gt;data&lt;/span&gt;layers. The HRU parameters extracted are: area, mean elevation, average land-surface slope, predominant aspect, predominant land-cover type, predominant soil type, average total soil water-holding capacity, and average water-holding capacity of the root zone.&lt;/span&gt; &lt;/p&gt;</dc:description>
