1. Big Pipeline Crossing Protection Project for Williams on the Guadalupe River, South of Victoria, TX. (near the harbor) 1.3 Million Dollars Took 3 crews 6 weeks to build!! Summer 2005

2. DEEP PLANTING HUNDREDS OF UNROOTED WILLOW POLES WHEN THE COLDEST DAY WAS 103 DEGREES

3. Bank erosion (lateral erosion) has exposed over 100 ft of pipeline, threatening pipeline integrity Co-designed by River Research & Design, Inc. & Submar, Inc. Contractor: Submar, Inc. Not a flashy stream, stays on the flood for months at a time Bed material: sand-silt-clay, not incised, rural. Pool-riffle-pool regime, slope < 1% Average width 100-150 ft, 10-18 ft tall banks Guadalupe River @ Williams Pipeline Crossing, South of Victoria, TX (near the harbor)

11. WILLOW PLANTING

12. Very hot down in Victoria, TX {103 degrees}. This was the coldest day, it hit 112 degrees some days. We cut several hundred willow branches & small trunks (3/4” to 1.5” butt diameter, 6’ to 8 ft long, soaked them for 10 days, then planted & watered them in (July-Aug time frame).

21. PRE-PROJECT-Guadalupe River @ Williams Pipeline-Derrick-Oct 1, 2004 PRE-PROJECT-From US project limit, looking DS @ exposed pipe & vertical bank, thalweg slamming straight into bank

23. PRE-PROJECT Guadalupe River @ Williams Pipeline-Derrick-Oct 1, 2004 PRE-PROJECT-Looking DS at the exposed pipeline, thalweg impacting bank.

24. 26 MONTHS LATER-Looking DS @ the protected pipeline, thalweg redirected & willow growth 8 to 16 ft tall after 2 years. 26 MONTHS LATER-Guadalupe River @ Williams Pipeline-Derrick 11-6-07

25. PRE-PROJECT Guadalupe River @ Williams Pipeline-Derrick-Oct 1, 2004 PRE-PROJECT-Looking DS at the exposed pipeline. Debris on pipeline, thalweg flowing under pipe.

26. 26 MONTHS LATER-Looking DS @ the protected pipeline, great willow growth US & DS of pipeline right-of-way (hydraulic roughness). 26 MONTHS LATER-Guadalupe River @ Williams Pipeline-Derrick 11-6-07

27. 26 MONTHS LATER-Looking DS, good sediment deposition on stone under dense 8 to 16 ft tall, 2”- 4” diameter willows. 26 MONTHS LATER-Guadalupe River @ Williams Pipeline-Derrick 11-6-07
