16 Applied UAS Projects Topography and Remote Sensing Monitoring Snow Depth and SWE Hayden Pass Burn Scar and Flood Alert Network

17 Rocky Mountain Snowpack Depth Noisy Basin Galena Summit Loch Vale Meadow

18 G.A. Sexstone, D.W. Clow, C.A. Penn Project beginning in FY 16 Installed three meteorological stations in headwaters Snowpack modeling and measurements to evaluate water resources forecasting

19 Estimate water volume by co-collecting snow depth measurements and computing SWE UAS equipped with laser altimeter, pulsed radar, data logger Linked to RTK GPS ground station Leverage existing USGS reference watershed USGS Halfmoon Creek near Malta, CO

22 Hayden Pass Burn Scar Freemont County, Colorado 22

23 Location Waldo Canyon Wildfire, Colorado (2012) Approximately 4 miles northwest of Colorado Springs, Colorado 2 fatalities 346 homes destroyed 28.5 square miles burned Waldo Canyon Basin, Pike National Forest Flash floods in July and August 2013 with 1 fatality Drainage Area: 1.76 square miles Mean Basin Elevation: 7,990 feet Mean Basin Slope: 45.4% Basin outlet located at US Highway 24

24 Gage Siting At-risk basins such as wildfire-burn scars Network design is transferrable Radar siting based on hydrology and basin characteristics Proximity to roadways and vital infrastructure Downstream from: Confluence points Land type dominated by rapid runoff Engineered structures, drainage, sewers Upstream from: Contractions (bridge openings or culverts) Backwater Populated and frequently flooded areas

25 Gage Siting Basin Delineation 4 Rapid Deployment Gages Located at: 1. 41% 2. 57% 3. 72% 4. 81% of the cumulative drainage area in the basin

26 Siting Basin Delineation

27 Equipment Typical Install 1. Non-contact velocity and stage radars 2. Data loggers and transmitters 3. Batteries with solar panel 4. Cable stay with Hilti bolt 5. Pelican case used as gage house

28 stage radar velocity radar Non-contact stage and velocity radar Sommer RQ-30 Measures continuous velocity and stage of flood waves

29 Data CDOT to receive near realtime transmits when stage or velocity alarms are tripped SMS texts and with latency of less than 30 seconds Alarms can be reconfigured remotely through the 3G modem and copied to the Iridium Short Burst Data (SBD) modem Decisions regarding a Plan of Action will be made by Colorado Department of Transportation based on data received
