Urban Modeling Component Improvements

People: Larry Roesner, Sybil Sharvelle, Chris Olson, André Dozier, Mazdak Arabi

Discussed:

SWAT urban modeling component
– curve number and green ampt (a lot of data – SSURGO soil data, NRCS – undefined soil classification -> class B soils no matter what it is, overlay connected imperviousness, uses modified USGS soil classification)
– percent impervious
– generate runoff
– treatment routines? build-up washoff (doesn’t have to be novel)
– large scale
– reduce stormwater for irrigation, etc.

Connection to economic modeling:
– Economic – city boundaries and irrigation districts
– 50-80 block groups

Water allocation
– conveyance constraints
– CDM & CWCB model? Larry will call Sue

To Do:

Link IUWM with the mapping tool and convert all to Java:
– Use it in the VB.NET version?
– Jeff Ditty

Work with utilities to get cost data (ask Wayne Miles with CDM in Charlotte):
– reclaimed water systems
– rain catchment
– arid region focus
– grey water reuse
– stormwater reuse (drive policy changes?)
– collection systems in water (data with Fort Collins)
– pumping wastewater
– # of FTEs and aggregate total miles of water (don’t disaggregate more than that for now)
– maintenance costs
– pipe network (data from cities) – flush the little lines
– approx. rehab costs
– 2% improvement every 100 years

Student?
– knows what they’re talking about it
– understands what the data needs
– to get data from utilities, need to be American, likely

For each of the major cities: Boulder, Denver Metro Area, Fort Collins,
