Performance Work Statement

A. General Information Project Title: Simulating the Fate and Transport of Phosphorus using the Mike Modeling System

1. Background:

Staff at the South Florida Natural Resources Center, at Everglades National Park (ENP) has developed a hydrologic simulation model of Everglades National Park and the surrounding area. The model is based on the DHI MIKE suite of hydrologic simulation modules including MIKE SHE and MIKE11. The model of Everglades National Park, referred to as M3ENP, has been calibrated for the period 1987 through 2010 and includes the relevant hydrologic processes including structural operations in the surrounding canal system. In addition to conventional hydrologic processes, basic solute transport processes of advection and dispersion have also been parameterized for the M3ENP model. This project is intended to expand the solute transport capability of the model by adding the Mike Ecolab module to comprehensively simulate the fate and transport of water quality parameters.

2. Purpose and Objective:

The purpose of this project is to develop a water quality simulation tool that can predict the fate and transport of reactive water quality parameters, particularly Phosphorus, given alternative water management scenarios.

The objective is develop an Ecolab template consistent with the existing M3ENP hydrologic model that is able to represent all of the relevant Phosphorus cycling processes including adsorption, desorption, inorganic/organic conversion, dissolution, precipitation, plant uptake as well as soil and groundwater interactions. In addition, general support for operations of the Mike 11 module and Mike SHE module will be expected.

3. Type of Contract Contemplated: This will be a firm, fixed price contract.

4. Period of Performance: This contract is for three (3) years; a base year and four (2) option years:

The exercise of any option year is contingent upon the availability of funds and the continued need for hydrologic modeling development and/or support.

B. CONTRACTOR REQUIREMENTS (Qualifications and Scope Of Work)
