Combining ArcView and naUTilus for Municipal Sewers By: Kimberly Martin CE 394K.3 – GIS in Water Resources 21 November 2000
Combining ArcView and naUTilus for Municipal Sewers Background on naUTilus AcrView / naUTilus Link Application to Austin Current Project Status
Overview of naUTilus Estimate VOC emissions from industrial sewer networks Fundamental Principles Fluid Mechanics Mass Transfer Fortran-based computer model Text-only Input and Output
naUTilus Model Sewer Characteristics Flow Data Branch Diameter Slope Drop Height Node Type Junction Manhole Drain Flow Data Concentration Temperature
Downfall of naUTilus USER FRIENDLY? No !
ArcView / naUTilus Interface Developed by Cindy How 33 Avenue Scripts Graphical User Interface Input Flow Data and Sewer Characteristics
Austin Sewer System ~70,000 Sewer Stretches ~70,000 Manholes Includes Abandoned and Proposed Sewers
Sewer Selection Research Project VOC Tracer Studies Model Calibration Large Scale Modeling of Municipal Sewer Emissions
Procedure Data Acquisition Use network features in Arc/Info Injection Point Sampling Point 1 Data Acquisition Use network features in Arc/Info Divide sewer network Apply naUTilus interface in ArcView Estimate missing parameters Sampling Point 2 Sampling Point 3 To Treatment Plant
Anticipated Results Visual display of emission results from OSBL Compare emission values with experimental results
Future Work This semester… In the next 18 months… Get the interface working Model first experimental stretch In the next 18 months… Model the other three experimental stretches Adjust model as necessary for municipal applications Model a large municipal sewer network
