A Really Fast Overview

Slide 3

Introduction AgDRIFT® Spray Drift Deposition Model AgDRIFT® consolidates a proposed general technique for assessing off-site affidavit of ethereal, plantation or ground connected pesticides, and goes about as an instrument for assessing the capability of support zones to shield delicate amphibian and earthbound territories from undesired exposures.

Slide 4

Program Overview AgDRIFT® was created under a helpful Research and Development Agreement, CRADA, between the EPA, USDA, US Forest Service, and SDTF.

Slide 5

Program Overview AgDRIFT® is an altered variant of AGDISP, a US Forest Service Model. Adjustments include: Took box to institutionalize computations Built-in illustrations Special fare capacities Improved vanishing capacity Emphasis float to accelerate the figurings

Slide 7

AgDRIFT® Two Versions Regulatory Version Two Extra Tiers: Tier I Aerial Tier II Aerial Direct access to all the SDTF field ponders

Slide 8

Tier I Aerial

Slide 9

AgDRIFT® Aerial Tier I Regulatory Risk Assessment Screening Tool "Sensible Worst Case" Implies most extreme worthy Deposition Not Maximum expected Deposition

Slide 10

Tier II Aerial

Slide 11

AgDRIFT® Aerial Tier II Regulatory Risk Assessment Advanced Registration Tool Designed for Label Mitigation Selected Inputs can be Changed Measurable Controllable Enforceable

Slide 12

AgDRIFT® Two Versions Public Version or Web Version No entrance to the SDTF field information No Tier I or Tier II Aerial Defaults values "Commonplace Application Conditions" Tier I & Tier II results can be recuperated by utilizing the Tier I default values. ( See manual )

Slide 13

Graphical Outputs Incremental Volume Fraction

Slide 22

Graphical Outputs Cumulative Fraction

Slide 23

Graphical Outputs Deposition

Slide 24

Graphical Outputs Pond-Integrated Deposition

Slide 25

Graphical Outputs Vertical Profile

Slide 26

Vertical Profile The aggregate sum of mass (pesticide) going in air at a given point down-twist as a component of tallness over the ground Think of it as the float before it stores Flux plane is set by the client Units mg/cm 2 Mass is saved

Slide 27

Graphical Outputs 1 Hour Average Concentration

Slide 28

1 Hour Average Concentration The aggregate sum of mass (pesticide) going in air at a given point down-twist as an element of stature over the ground weakened with the volume of air the goes through a similar point (region) in space The volume of air depends on the wind speed Units g/l

Slide 29

Toolbox (Aquatic Assessment) Water body EPA Pond EPA wetland User Defined Application Rate Calculations Buffer Fraction of connected (rate) Fraction g/ha Pond fixation g/l

Slide 30

Toolbox (Terrestrial Assessment) Terrestrial Field Deposition Point Average Application Rate Calculations Buffer Fraction of connected (rate) Fraction g/ha g/cm 2

Slide 31

Toolbox (Spray Block Assessment) Water body EPA Pond EPA wetland User Defined Application Rate Calculations Buffer Fraction of connected (rate) Fraction g/ha g/cm 2

Slide 32

Toolbox (Spray Block Assessment) Spray piece appraisal: Ask yourself the accompanying inquiry. On the off chance that the zone to be showered is 125ft from the delicate region. How substantial of a territory would I be able to splash before I surpass a testimony of one percent of the application rate?
