Hydrologic Budget Analysis And Numerical Simulations Of Groundwater Flow In Los Alamos Canyon Near Los Alamos, New Mexico, Robert Norman Gray
Hydrologic Budget Analysis And Numerical Simulations Of Groundwater Flow In Los Alamos Canyon Near Los Alamos, New Mexico, Robert Norman Gray
Earth and Planetary Sciences ETDs
A hydrologic budget analysis for the Los Alamos Canyon watershed was prepared including annual budgets for the 1993, 1994, and 1995 water years and detailed budget calculations for the upper basin and middle/upper canyon areas covering nine separate stress periods from 7/10/94 to 11/2/95 corresponding to varying alluvial aquifer behaviors. Data sources included daily measurements of precipitation and snowpack depths, streamflow discharge, and latent heat energy flux from which evapotranspiration rates were determined. Average annual precipitation rates over the watershed varied from ~23 to ~31 inches during the analyzed periods. The annual evapotranspiration component was determined to represent between ~ …

The Terraces Of Cochiti Canyon: Soil Development And Relation To Tectonism In The Pajarito Fault Zone, Scott Benjamin Aby
Earth and Planetary Sciences ETDs
The history of motion on splays of the Pajarito Fault Zone in the area of Cochiti Canyon in the Jemez Mountains is examined using morphometric techniques and investigations of river terrace soils and deformation. Hypsometry, sinuosity and long-profile analysis all suggest that the main splay of the Pajarito Fault has been active in the late Pleistocene and possibly Holocene, but no calibration is available that numerically constrains this activity. Terraces were mapped and correlated based on soil development and landscape position, Correlation revealed the presence of three strath terraces between 87 and 18 .5 meters above present grade and one …
