Overview & Objectives:
The objective of determining water-delivery restoration scenarios is supported by the performance-measure optimization-modeling. This technique utilizes the optimization code UCODE to analyze model output and develop model input for the SICS application to produce an optimal water-delivery scheme to satisfy ecologic objectives. The FBFKFS developed performance-measures specify ideal ranges and fluctuations in relevant parameters, such as salinity. These are used as guiding parameters for the UCODE optimization. This same technique can be applied to the TIME application and other hydrologic models used in the region.
The SICS model output has been coupled to components of the ATLSS ecologic modeling suite, in order to supply the necessary hydrologic information for determination of fish population dynamics.
Specific Relevance to Major Unanswered Questions and Information Needs Identified:
TWRI Book 6, Chapter 1, Section B A model for simulation of surface-water integrated flow and transport in two dimensions: SWIFT2D user's manual is the user's manual for the SWIFT2D code and OFR 2004-1195 Assigning boundary conditions to the Southern Inland and Coastal Systems (SICS) model using results from the South Florida Water Management Model (SFWMM) describes the linkage of SICS to the SFWMM.
The SICS/ATLSS coupling has been described in a conference paper at the International Environmental Modeling and Software Society (IEMSS) 2004 conference.
A presentation and abstract on the SFWMM linkage was given at the November 2004 GSA conference.
The NCER conference in December 2004 featured several extended abstracts and a fact sheet about SICS, TIME and ATLSS.
The modifications to SWIFT2D for wetland application are described in SWIFT2D user's guide for application to coastal wetlands in connection with underlying ground water OFR 2005-1033.
The SICS/ATLSS coupling utilizing scenarios based on performance-measure optimization is presented in a paper for the First All-USGS Modeling Conference, November 2005.
The results of the performance-measure optimization modeling are described in an abstract for the 2005 Florida Bay Science Conference as well as an abstract on the TIME model development at the same conference.
Title of Task 1: Use of optimization-modeling techniques in SICS for scenario optimization
Task Summary and Objectives: The primary motivation in the SICS/TIME modeling effort is to lend insight into Restoration efforts. By utilizing optimization modeling techniques, the Restoration performance measures, which define target salinities and water-levels for ecologic purposes, can be used as objective functions and the boundary conditions of the model are optimized to satisfy the performance measures. These desired boundary conditions then can be related to the regional water-delivery scheme. This technique requires multiple model executions to develop stochastic representations of the effects of boundary variations. The optimization model is constructed to act as a control shell for the SICS model, with the hydrologic output from the SICS model used by the inverse model shell for the optimization procedure.
The task for FY 2006 is to continue the development which has produced a performance-measure optimization of inflows to Everglades National Park based on criteria for salinity in zones 1 and 2 of the FBFKFS performance-measure criteria. This continued development involves extending the simulation period, including more performance-measure zones and modifying the representation of the salinity criteria in the optimization. A USGS SIR report will be developed in FY2006 describing the development and results.
Work to be undertaken during the proposal year and a description of the methods and procedures: The current optimization for two performance-measure zones, Joe Bay and offshore Joe Bay, will be expanded to include zones such as the West Lake area and Little Madeira Bay. The optimization period will be expanded to the full 7 years. Variations in specifying the target criteria will be tried. The optimized water-delivery schemes will be provided to the ecological modeling to determine the effects of the proposed changes. The report will include a background of the SICS model used, the UCODE optimization technique, the incorporation of SICS into UCODE, the method of incorporating performance measures, the criteria used to modify water deliveries, and the results of the study.
