<br />2 <br /> <br />and 3), is used to simulate runoff volumes that could be expected with the conditions found after <br /> <br />the May 1996 wildfire. The runoff hydrology modeling is performed using parameter values <br /> <br />indicative of both unburned and burned soils. A better understanding of the physical processes <br /> <br />and variables that caused damage in the Buffalo Creek watershed may aid in post-fire <br /> <br />remediation and the best management practice (BMP) that can be applied to similarly affected <br /> <br />watersheds. <br /> <br />The purposes of this study are to compare and attempt to explain discrepancy between the <br /> <br />recurrance probability of the July 12th rainstorm and the recurrance probability of the resulting <br /> <br />flood, and explore the possible effects of wildfire on basin hydrology. The following objectives <br /> <br />will be used to meet this goal: <br /> <br />1. Use L-moment statistics to define a climatically homogeneous region in Eastern <br /> <br />Colorado; <br /> <br />2. Identify the 1,2,5, 10,25,50, 100 and 500-year, 24-hour rainfall event for <br />Buffalo Creek; <br /> <br />3. Disaggregate the 24-hour rainfall estimates listed above into I-hour storms; <br /> <br /> <br />4. Use the Hydrologic Engineering Center (HEC)-1 model to estimate the runoff <br /> <br /> <br />response of the I-hour storm through a small sub-watershed of the Buffalo Creek <br /> <br /> <br />basin (Sand Draw). <br />
