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)

4
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

8
Soil, Landuse, and Topograph
9
Delineation of the Sub-watershed
Crooked Creek

based on the RF1 and RF3 reach networks

Runoff by Default values on the simulation
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.
