The Surface Water Toolbox
Customized interface built on the open-source MapWindow GIS software
Windows Desktop application Retrieval, Management, and Visualization of
hydrologic time-series data in a variety of sources and formats o USGS National Water Information System (NWIS) o National Oceanic and Atmospheric
Administration National Climatic Data Center (NOAA)
o International data Perform data manipulation and hydrologic analysis
of streamflow-hydrograph data. Integrated Design Flow tool: SWSTAT + DFLOW
Demo Outline
1.Overview of software 2.Set up project 3.Alternative data import:
1.Read data from script 2.Download data from Station IDs
4.Analysis: Integrated Design Flow tool a.N-day, Frequency Analysis b.DFLOW c.Outlier Detection with R script
5.Batch job example
Setup a new project
• Select a HUC-8 watershed • Automatically download a base set of data
including streamflow gage locations • GIS data layers are automatically reprojected to a
desired map projection and labelled accordingly • User can start downloading data and be associated
with the project
Batch Run: Save Spec File
• SWSTAT and DFLOW batch runs are done separately • Spec files specify default/global and group-specific
analysis parameters • There can be as many groups of streamflow
datasets as user would like • Each group can have its own parameters that
supersede the global default • Spec files are saved with timestamp e.g.
BatchRun_SWSTAT_8_16_2016 2_47_05 PM.txt or BatchRun_DFLOW_8_22_2016 2_50_20 PM.txt
