The application is particularly suited for watersheds because it efficiently provides information management and spatial query mechanisms to capture and store vast amounts of data that can be acquired over the life of a project.  

The data management system allows for easy entry and retrieval of a wide variety of watershed data. 

          Watershed Monitoring:

The user can easily download new data acquired from a stream gauge data logger or manually enter stage levels.  The application provides a graphical display of stream flow and base flow for any defined time period.  The program will automatically calculate minimum, average and maximum stream flow, Q7, discharge ratio Q25/Q75 and percentage baseflow.

The riverbed cross-section at stream gauge locations can graphically represented.  Measured stream levels (H) are then converted to flow values (Q) using a correlations power function (with user-calibrated correlation parameters), the flow rating curve displays the observed and calculated flow vs. stream level.

The user may set the water budget parameters (precipitation, change in groundwater storage, evapotranspiration and groundwater pumping) for a given time period and the application will calculate the water budget.

          Watershed Management:

Visual assessment data for studied locations within the watershed can be included into the database, visual assessment criteria includes instream cover, fine sediments, flow patterns, bank conditions, pressures in the riparian, width of riparian zone, litter and overall assessment.

The user can easily include some or all of the following survey data to the database: bankfull width, sinuosity, estimate of discharge, water surface slope, mean bankfull depth and Rosgen Classification stream type.

The following analytical water quality data can be included into the database: turbidity, water temperature, pH, conductivity, dissolved oxygen, alkalinity, water hardness, total phosphate, ortho phosphate, ammonia as N and nitrate as N.  The data is displayed in graphical form showing the evolution of each parameter through time.

The Report Module included in both the Watershed monitoring and Watershed Management sections of the program allow the user to quickly and easily form tables to summarize specified data at selected monitoring stations.

The application includes a descriptive user’s manual with definitions of terminology and an example problem.
