Abstract: A numerical model study of the Rio Grande through Espanola, NM, was conducted to evaluate flood-event channel response to the proposed levee system on the west bank of the Rio Grande. A second objective was to evaluate the flood-event behavior of the Rio Grande streambed at the mouth of the Santa Cruz River. To perform the analysis, the one-dimensional sedimentation model (TABS-1) was applied. The model was used to reproduce historical flow and sedimentation patterns through Espanola and to determine the impact of the proposed levee system on the bed of the Rio Grande. The model indicated no degradational or aggradational trends resulting from the proposed levee plan within the study area. Based on the 1979 hydrograph results, there did not appear to be a sediment problem from the Santa Cruz River. The Rio Grande was capable of effectively removing sediments delivered from the Santa Cruz River. In summary, the proposed levee plan exhibited no adverse impact to the Rio Grande from a sedimentation standpoint.
