BASINS

• BASINS is a multipurpose environmental analysis
  system for use by regional, state, and local
  agencies in performing watershed and
  water-quality based studies.
• Integrates
• GIS ARC View
• Extensive Database for the entire US
• Water Quality Models Tools

3
Components of BASINS

• Nationally derived databases with Data Extraction
  tools and Project Builders
• Assessment Tools (TARGET, ASSESS, and Data
  Mining) that address large and small-scale
  characterization needs
• BASINS Utilities including watershed Delineation,
  import, Landuse reclassification, DEM
  reclassification
• Watershed Characterization Reports
• Non-Point Source Model (NPSM) and Water Quality
  Model (QUAL2E)

Non Point Source ModelNPSM (HSPF v11)

• HSPF is a very complex model. However, it is
  structurally modular permitting the user to
  isolate and focus on elements of interest while
  bypassing other modules and their activities.
• The model considers a basin or watershed
  comprising of 2 segments
• Land Segment pervious and Impervious
• Water body (Streams, lakes, reservoirs)
• HSPF Modules
• PERLAND the module that simulates pervious
  land segment
• IMPLAND the module that simulates impervious
  land
• segment
• RCHRES the module that routes runoff through
  reservoir while simulating instream
  processes

5
Hydrology in NPSM

• Hydrologic Components
• Rainfall or Snow
• Interception
• Depression Storage
• Evapotranspiration
• Infiltration
• Surface Storage
• Runoff
• Interflow
• Groundwater Flow

6
Objectives

• Run BASIN/HSPF modeling program and evaluate
  runoff predictions using BASINS default
  parameters
• Evaluate the sensitivity of key hydrologic
  parameters
• Calibrate the model
• Evaluate the calibrated model

Site Description- Craypan Watershed
in Missouri

• Located within Monroe and Shelby County in North
  Central Missouri
• Encompasses 111 sq.mi. (71,204 acres)
• A tributary of the North Fork of the Salt River,
  which empties into Mark Twain Lake

The default parameters are largely divided into
three categories Water Balance, Groundwater, and
Surface Runoff.

Future Work

• According to Crooked Creek Watershed Project,
  an atrazine, sediment, and nutrient loading are
  concerning in this watershed. In the future,
  when simulating this model, we should consider
  important environmental parameters.
