PROGRAM OVERVIEW
• 2012: Public and private
partners engage state
legislature to fund program
• June 2012: LID Training
Steering Committee convened
• 2012‐2013: Washington State
LID Training Plan developed:

trainings (September 2014
through May 2015)
• 49 trainings offered in
western and eastern WA first
year
• 45 trainings scheduled for
western and eastern WA in
current phase (through June
2016)

AGENDA
introduction
LEARNING OBJECTIVES
1. Gain an intermediate to advanced level of
knowledge using WWHM and MGSFlood to
predict pre‐ and post‐development flow volumes
and durations.
2. Learn intermediate to advanced level skills to
size bioretention, permeable pavement, and
vegetated roofs in residential and commercial
settings using WWHM and MGSFlood.
3. Understand the advantages and limitations of
WWHM and MGSFlood and are introduced to
additional modeling tools for specific predictions

Advanced Modeling Topics: Importing Precip
Select Tools
Advanced Modeling Topics: Importing Precip
Import Dataset – allows users
to import any time series
data in comma‐delimited file
or text file.
Advanced Modeling Topics: Importing Precip
Specify time series type. Can
be precipitation, flow,
evaporation, or stage data.
Specify start date, end date,
timestep, and the timestep to
be used in the model.
Advanced Modeling Topics: Importing Precip
Select missing value method.
A WDM data set number
between 1 and 9999 must be
assigned.
Advanced Modeling Topics: HSPF Parameters
PERLNDS – Pervious Land Segments – model parameters that
define interception, infiltration, and movement of moisture through
soil.

Parameters
View / Edit IMPLNDs
IMPLND – parameters for
simulation of runoff and
water quality constituents
from impervious land
areas.
PRLND – parameters for
simulation of runoff and
water quality constituents
from pervious land areas.
Advanced Modeling Topics: Editing HSPF
Parameters
Change IMPLND by land cover.
Advanced Modeling Topics: Editing HSPF
Parameters in WWHM
LSUR – overland flow length (ft)
SLSUR – slope of overland flow (ft/ft)
NSUR – Manning’s n
*Note that the 2012 SWMMWW (Amended 2014) only allows the user to edit LSUR, SLSUR, and NSUR as
these are parameters whose values are observable at an undeveloped site, and whose values can be
reasonably estimated for the proposed development site.
