SUMMARY: On August
19, 2013, the MPWMD Board approved entering into an agreement for services with
Right on Q Hydrogeology (Michael Hutnak) for a not-to-exceed
amount of $56,800 to assist District staff in developing a GSFLOW (Groundwater and
Surface FLOW) model. This model is now called the Carmel River Basin Hydrologic
Model. Currently, MPWMD, U.S.G.S. and Right on Q Hydrogeology have been
working on developing a set of versions of the CRBHM that represent various
scenarios with respect to the future of Los Padres Reservoir (dredging versus
removal) and reduced pumping by Cal-Am (compliance with the CDO 2009-0060). Now
that these models are nearly complete for a set of specific scenarios, the
National Marine Fisheries Service has requested a sensitivity analysis of some
of the hydrologic properties of the model, which would help them understand how
changes in certain parameters (aquifer properties) impacts results of the model.
In addition, results from the model runs come in the form of large tables with
flow data at various locations along the river. These large data sets are best
processed by scripts that allow analysis by producing graphs and summary
statistics. Carrying out a sensitivity
analysis and the development of these scripts is beyond the original scope of work.
Approximately $4,020 remains in the current contract with Right on Q Hydrogeology. Staff is requesting a contract amendment that would add an additional $15,000 of authorized funds to complete a sensitivity analysis of various model parameters and development of Matlab scripts that will process model output. This additional spending is included in the 2019-2020 Budget adopted by the Board on June 17, 2019.
RECOMMENDATION: Staff is requesting the Board authorize additional spending in the amount of $15,000 to carry out sensitivity analysis of the CRBHM and the programing of scripts that process the large output files resulting in graphs and summary statistics. The original contract was for a not-to-exceed amount of $56,800. This amendment would add $15,000 to the current contract for a not-to-exceed amount of $71,800.
DISCUSSION: Right
on Q Hydrogeology has been part of the modeling team since 2013 when the
District started moving forward with the development of the CRBHM. Right on Q
Hydrogeology developed many of the original Matlab
scripts that take the pumping data from Excel spreadsheets and converts them
into a format that is recognized by GSFLOW.
