The "Uniform" folder contains the HMS model utilizing precipitaiton
uniformly distributed over the basin.
	-Depth Area Analysis runs are generally set up to run,
	but analysis points will need to be added for any nodes where
	results are needed.  
	
	-USACE reservoirs were disconnected from downstream elements
	for depth area analysis runs.  A sensitivity test was performed
	to see what scenario produced higher discharges at the first junction
	 downstream of the dams.  Because of area reduction, having the 
	reservoirs disconnected produced higher discharges and was used for
	final depth area anlalysis runs.

The "Elliptical_Storm" folder contains the HMS model utilizing 
and elliptical design storms.  The results from this model are 
more reasonable for the very large drainage areas as discussed in main report.
	-In order to obtain peak discharge frequency results, the	
	appropriate preciptiation dss file will need to be copied
	into the appropriate location.  There is a seperate TrialDSS.dss 
	file for each junction in the model where the drainage area 
	exceeds 400 square miles. For example, if the 100-yr peak elevation 
	results for Lake Bridgeport are desired, the TrialDss.dss file 
	located within the 
        "Precip\Bridgeport_Reservoir_100yr48hr_AbvCrockett"
	folder will need to be copied into the 
        "Precip\0_HMS_Input" folder.  
        The reason for this is because an elliptical storm
	has been optimized for each particular junction and has
	a unique volume total, storm rotation, and center location.
	If the correct precipitation dss file for each specific junction
	is not used, the model will not produce the intended results.
