a disposal site. Using these equations, however, resulted in large losses of material over 

 short periods of time that were unrepresentative of the mounds studied under the DAMOS 

 program. These inconsistencies seemed to be the direct result of the volumetric sediment 

 transport rate versus mean flow relationship used in the Equation Workbook. 



SUMMARY 



The present version of the DAMOS Capping Model adequately provides the tool 

 needed by managers at NED to predict the configuration of a disposal mound and estimate 

 the amount of capping material required to isolate any containments in that mound. 

 Assumptions made in developing this model were necessary to reduce the input parameters 

 required of the user and, therefore, to facilitate its use on any PC-compatible computer. As 

 more accurate information is obtained from tightly controlled disposal operations and mass 

 balance experiments, the model may be refined to better reflect these results.
