Mixing Zones (n): 1.Mixing zones are limited regions in rivers, lakes and coastal areas where the initial dilution (dispersion) of point-source wastewater discharges occur

CTD = Conductivity, Temperature, Depth sensor Used to find plumes and determine mixing zones Data collected as text files Photo: mixzon.com
Sensor is dropped in Downcast …then pulled up Upcast We only want upcast data We only want the data points for the maximum values
Data saved as raw text Interns and employees manually find upcast Maximum values manually found Slow, inefficient
Designed an algorithm Wrote an application to implement algorithm Used C++/CLI programming language
Output as smaller text files Output to GIS shapefile GPS coordinates make points Attribute data attached to coordinate points Maps can be created from these points
User can select multiple files Output is shown while processing Graph is shown for each of the measurements Maximum values are shown with lines and in text User can select which files graph to look at Status strip shows sensor information
Helped with field data collection
Redesigned MixZons intranet site New UI Platform-independent, w3c-compliant code Used PHP, HTML, CSS
Microsoft C++/CLI New programming language Mixing zone terminology Understanding of GPS/GIS Environmental science in the field Experiencing a professional work situation
