Geologic Analysis, Ventura River Watershed

 This memorandum summarizes geologic analysis performed for the Ventura River Watershed (VRW) by Daniel B. Stephens & Associates, Inc. (DBS&A) in support of numerical model development. The geologic analysis presented herein will be used, in conjunction with other information as described in the project Study Plan (Geosyntec and DBS&A, 2019), to assign three-dimensional model layer geometry, initial model hydraulic properties (e.g., hydraulic conductivity), and the presence of boundary conditions. This geologic analysis is based on data available to DBS&A at the time the analysis was conducted. We anticipate that development of the VRW geologic conceptual model may be revised as additional data becomes available and as numerical model development proceeds.
