Martha K Watt

Biography

Martha Watt is a hydrologist at the New Jersey Water Science Center (NJWSC) where she has been the project chief of the Model Maintenance Program since 2003.  This project is responsible for archiving, maintaining, updating, and sharing the groundwater flow models that were completed in the NJWSC.  The program was started in 1995 and since that time 22 models have been checked, validated, and archived.  The models are posted to the NJWSC webpage where they are available to the public.  Martha has standardized the checking and archiving process and supports the groundwater projects within the NJWSC.  She has worked as both project staff and project chief on many groundwater studies.  Her work on a series of surficial aquifer studies that compiled relevant information on the major surficial aquifers within the NJ Coastal Plain was the groundwork for later modeling studies.  Her work on a variety of groundwater modeling studies provided the experience needed to successfully manage the Model Maintenance Program.

2003-Present, Project chief of the Model Maintenance Program:  This program was started in 1995 to maintain and update groundwater flow models that are constructed in the New Jersey Water Science Center (NJWSC).  All models are validated and documented. Older models are updated to more recent model code. Many (22) of the models developed in the NJWSC are posted on our public website. Checking these models requires knowledge of MODFLOW and all associated packages.  Zonebudget, ArcGIS, and pre- and post-processing programs assist in data manipulation and checking.  The Model Maintenance program also provides project support for other modeling studies within the NJWSC.  Existing groundwater flow models are used to provide boundary flows for smaller local models. Major revisions are done periodically on widely used models.  The NJ Regional Aquifer System Analysis (RASA) model is being updated to include Maryland and Delaware, a fully 3-D framework, updated hydrologic parameters and withdrawals, and refined streams and recharge.  

 

1992-2003, Project staff on modeling projects: Worked with MODFLOW and MODPATH computer programs to model the problem.  Assembled model-data sets such as base flow and water use, ran model scenarios, analyzed model output data, and compiled figures and tables for publication.  

Toms River project—A model of the unconfined Kirkwood-Cohansey aquifer system in the NJ Coastal Plain was developed that evaluated the groundwater flow and its interaction with surface water and the response to withdrawals.

Randolph Township, Northern NJ—An existing groundwater flow model of carbonate rock and valley-fill aquifers was used to define contributing area to withdrawal wells under different withdrawal conditions.

Pennsauken Township—Two groundwater flow models were completed for this area.  One model used particle tracking to define the contributing area for the public and non-community water supply wells.  The second model evaluated the groundwater flow system and the advective transport of chromium contaminated groundwater.

 

1998-2000, Project chief of Outreach project:  This project produced a report titled “Hydrologic Primer for NJ Watershed Management” which provides a general understanding of hydrology concepts in non-technical terms and presents summaries of hydrologic data collected in NJ.  This report was designed to provide water managers with the information needed to make better watershed management decisions and won the David A. Aronson Outstanding Report of the Year Award for 2001.

 

 

1987-91 and 1999-2003, Project chief of Surficial Aquifer Studies:  The surficial aquifer studies were completed to evaluate the unconfined aquifer system in the NJ Coastal Plain for use as a potential source of water. Many of these projects were the ground work for future modeling studies.
