22. Discover Texas Through Maps A collection of maps to promote exploration and discovery of interesting Texas features. Presenter: Nancy Heger
23. Development of Middle Trinity River floodplain inundation model for assessing Alligator Gar recruitment Kairm Aziz and Clint Robertson - River Studies, TPWD Nolan Raphelt - TWDB
24. Floodplain Inundation Modeling ´  It’s known that Alligator Gar spawn during flood pulse events. ´  Purpose of this study is to define the characteristics of these flood pulse events that lead to successful recruitment. ´  Utilize GIS to develop floodplain inundation model
25. Trinity River Basin Dallas/FT Worth Houston Middle Trinity Study Area
26. GIS Data •  50cm,1m and few 5m DEMs (~1,500 tiles) collected from TNRIS and TRA •  HEC RAS model from Tarrant Regional Water District •  Texas Ecological Mapping Systems •  ArcMap and Erdas Imagine
27. Merge DEMs into three reaches for data management purpose Reach 1 Reach 2 Reach 3
28. Developing Modeled Water Surfaces: ´ Using HEC RAS model developed by Tarrant Regional Water District, cross sections were produced for flood flows of: 5, 10, 15, 20, 25, 30, 35, 40, 50, 60, 70 and 80K cfs ´ Water surface elevations generated for each discharges
29. Cross section data imported from HEC RAS Reach 2 80K example
30. WSE from points spatially joined to transect lines for TIN development Reach 2 80K example
31. TIN generated to produce a smooth water surface and converted to raster Reach 2 80K example
32. Water surface raster used to query DEMs and calculate inundation extent using ERDAS Imagine Reach 2 80K example
33. Total calculated inundated area. Reach 2 80K example
34. Ran intersect with river to select only areas that were connected to the river excluding detached areas and areas behind levees. Reach 2 80K example
35. Floods of May and June 2015 provided an opportunity to collect ground truth points Inset 1 Inset 1
36. Inset 1 GPS points and discharge measurement at 56k cfs Observed difference of 0.~5m 2 miles wide
38. Inundated Habitat Data ´ Determine types and areas of habitats being inundated ´ Vegetation classes ´ Used the Ecological Mapping Systems generated by TPWD
39. •  Statewide current vegetation data •  Spatial Resolution •  10meters •  Thematic Resolution •  398 mapped habitat types •  Abiotic variables (Enduring Features) •  Ground verified •  >14,000 field data points •  Accuracy •  74% to 90% •  Anthropogenic effects •  19 Invasive types mapped Ecological Mapping Systems Data-Inputs Land Cover Digital County Soils Final Mapped Vegetation Types Slopes Flood Plain
40. EMS clipped to inundation shapefile and exported to table This was done for each of the target flows Have since gone back and refined this process using a depth range of .2m to 2m Reach 2 80K example
41. Alligator Gar Spawning Habitat Previous work in LA and ARK show preferred habitat for spawning gar such as open canopy vegetation types: Examples: ´ Flooded herbaceous vegetation ´ Flooded shrubs Allen, Y.C., Kimmel, and G.C.

Baton Rouge Fish and Wildlife Conservation Office report.
42. Inset 2 Here is where its gets exciting!

45. Selected vegetation classes
46. Floodplain Hardwood Forest Floodplain Deciduous Shrubland Floodplain Herbaceous Vegetation Floodplain Seasonally Flooded Hardwood Forest I had Matt Symmank look at these and he confirmed the area of interest was Herbaceous Vegetation EMS classes where spawning gar were found:
