A Study on the Low-Flow Capacity Analysis of Small River

&nbsp;&nbsp;To stand river capital planning, flow situation like low-flow in small rivers used to be calculated as the ratio of area by flow situation in other large rivers. Which is because the small rivers don&quot;t have a survey about the small watershed area water-level and discharge. Therefore, this study has examined the low-flow estimation computerizing the dearth water discharge amount in small rivers.<BR>&nbsp;&nbsp;The low-flow statistics which is calculated by independent variables of the watershed area(A), the average basin slope(S), the void ratio(V), the volume of pores(V&lt;SUB&gt;f&lt;/SUB&gt;), the mountain ratio(M) and the year average amount of rainfall(R) is as follows.<BR>&nbsp;&nbsp;Q = 0.00245 A&lt;SUP&gt;0.516&lt;/SUP&gt; S&lt;SUP&gt;-0.024&lt;/SUP&gt; V&lt;SUB&gt;f&lt;/SUB&gt;&lt;SUP&gt;0.014&lt;/SUP&gt; M&lt;SUP&gt;-0.061&lt;/SUP&gt; R&lt;SUP&gt;0.079&lt;/SUP&gt;
