Sediment Quality and Depositional Environmental of San Elijo Lagoon

    The purpose of this project is to characterize the make-up for the surficial sediments and the historical  depositional environment of San Elijo Lagoon. Many of the restoration and enhancement projects that were suggested in the San Elijo Enhancement Plan (County of San Diego Dept. of Parks and Recreation in 1996) and described in the San Elijo Lagoon Action Plan (Gibson and Thum 1998) key on future deepening, widening, and extension of the existing tidal channel system within the lagoon. Also, evaluation of the design and the success of any future channel and basin enhancement projects will depend upon an understanding of the present depositional environment. In addition, in order to develop a plan for future excavation and disposal of lagoon sediments, the sediment grain size composition must be characterized and the potential presence of chemical contaminants throughout the lagoon must be defined. It is also important to understand the conditions under which the sediments may function as a sink and/or a source of nutrients and contaminants.

     Los Angles Regional Quality Control Board ($25,000); The San Gabriel River Watershed; GPS and Observational Report on the San Gabriel River from the Whittier Narrows region to Seal Beach.


GRANTS and CONTRACTS IN-REVIEW


     Long Valley Hydrologic Committee – Mammoth Pacific Corporation ($75,000), Hydrologic Monitoring In Long Valley Caldera (Co-PI: Laton W.R. and Foster J.)

Taylor Yard and Los Angeles River Preliminary Groundwater and Surface Water Study - Groundwater Model of Taylor Yard and Vicinity Los Angeles, California

    The following report is confined to the groundwater modeling aspects of the overall report. A computer model of the Taylor Yard aquifer system was developed to predict the interaction of surface water with that of the local groundwater. The model used was Modflow, a U.S. Geological Survey modular finite-difference groundwater flow model. The version used for this model is Visual Modflow 2.3 (Version 2.8.2.52) by Waterloo Hydrogeologic, Inc.
