Venture connection. Difficulties of STARMAP (EPA STAR):Addressing science needs Clean Water ActIntegrate science with states/tribes needsAssisting analysts to test reasonable speculations produced utilizing comprehension of biological procedures. Objective: to discover measures that all the more nearly speak to our comprehension of how environmental procedures are working.

Slide 1

Utilitarian linkage of watersheds and streams: ArcGIS FLoWS instruments David Theobald, John Norman, Erin Poston, Silvio Ferraz Natural Resource Ecology Lab, Dept of Recreation & Tourism, Colorado State University Fort Collins, CO 80523 USA 26 July 2005

Slide 2

Project setting Challenges of STARMAP (EPA STAR): Addressing science needs Clean Water Act Integrate science with states/tribes needs Assisting analysts to test valid theories produced utilizing comprehension of biological procedures Goal: to discover measures that all the more nearly speak to our comprehension of how environmental procedures are working

Slide 3

From watersheds/catchments as progressive, covering areas… River continuum idea (Vannote et al. 1980)

Slide 4

… to network of catchments Benda et al. BioScience 2004

Slide 5

SCALE: Grain Landscape River Network Microhabitat COARSE Climate Atmospheric affidavit Geology Topography Soil Type Network Connectivity Stream Network Nested Watersheds Connectivity Flow Direction Network Configuration Drainage Density Confluence Density Vegetation Type Basin Shape/Size Land Use Topography Segment Contributing Area Segment Tributary Size Differences Network Geometry Localized Disturbances Land Use/Land Cover Reach Riparian Zone Riparian Vegetation Type & Condition Floodplain/Valley Floor Width Cross Sectional Area Channel Slope, Bed Materials Large Woody Debris Overhanging Vegetation Substrate FINE Biotic Condition, Substrate Type, Overlapping Vegetation Detritus, Macrophytes Shading Detritus Inputs Biotic Condition

Slide 6

USGS NHD, NED

Slide 7

FLoWS v1 instruments for ArcGIS v9.0… Will move to v9.1

Slide 8

"genuine" catchments "adjoint" catchments Segments Pre-handling portion contributing ranges (SCAs) Automated depiction Inputs: stream arrange (from USGS NHD 1:100K) geography (USGS NED, 30 m) Process: "Develop" contributing zone far from fragment until ridgeline Uses WATERSHED summon

Slide 9

Segments are connected to catchments 1 to 1 relationship Properties of the watershed can be connected to organize for aggregation operation

Slide 10

Landscape systems with Python Need to speak to connections between components Using chart hypothesis, systems Retain attach to geometry of elements Flow connections table (like NHD, however stream sorted!) Implementation in ArcGIS Geometric Networks (ESRI – muddled, moderate) Landscape Networks: Open, basic, quick Began with VBA (1.5 years), moved to Python (2 months)

Slide 11

Selections Downstream

Slide 12

Example: Flow alteration Deynesius and Nilsson, Science (1994) – 77% of upper 1/3 of northern half of the globe waterways are firmly or modestly influenced -F = controlled/add up to station length -R = % of VMAD (total supply live, net limit) Network-based stream adjustment 1. Level of adjustment to stream = total yearly stream – cum. dam max. capacity: Q\' = Q-S 2. Extent of adjusted to VMAD ("common") stream: F = Q\'/Q Collaboration with Aquatic environmentalists (Poff, Merritt) RCL TCL

Slide 13

Slide 22

Next strides Increase scope of utilizations Attach extra datasets to SCA database Land cover (urban, ag, "normal") Historical, present, future lodging thickness Indexing of National Inventory of Dams?
