Water Quality Monitoring and Modeling

F. X. Browne, Inc. has a nationwide reputation in the study and modeling of lakes and streams.  We have written chapters in nationwide EPA Manuals and in two McGraw-Hill environmental handbooks.  F. X. Browne, Inc. performs all water quality management studies in house and has full capability to collect and evaluate water quality and biological samples from streams, rivers, lakes, and reservoirs.  

Most of the watershed management projects performed by F. X. Browne, Inc. include the monitoring of water quality and non-point source pollutants. Available equipment includes manual and automated water sampling equipment, sediment samplers, manual and automated stream flow meters, temperature and dissolved oxygen meters, and sounding equipment.

Water Quality and Watershed Modeling 

Many of the watershed management projects performed by F. X. Browne, Inc. include modeling of pollutant loadings and in-stream water quality to develop and/or evaluate TMDLs.

F. X. Browne, Inc. has used a variety of models to evaluate water quality; these models have included Unit Area Loading (UAL) models, statistical models, mass balance models, steady state models such as QUAL2E and DOBAL, and stormwater management models such as the Penn State Runoff Model (PSRM), GWLF, EPA stormwater model (SWMM), AGNPS, BASINS, WASP, STORM, HSPF model, non-point source model, DR3M-QUAL, Pg Urban Catchment model, ANSWERS, CREAMS, HEC-RAS, HEC-HMS, and TR55. Most of these models were run using water quality and quantity data collected by F. X. Browne, Inc.
