Thurgood Canyon, located on White Sands Missile Range (WSMR), contains an alluvial fan that is bisected by a primary installation road and is in the proximity of sensitive fish habitats. This project was initiated to determine if and how sensitive fish habitats at the base of the fan are impacted by the existing drainage infrastructure and to assess the condition and sustainability of the existing transportation infrastructure. Findings show that the current drainage infrastructure maintains flow energy and sediment carrying capacity further down the fan than would occur in its absence. However, frequent to moderately rare (small to medium) flood events dissipate over 2 km from sensitive habitat, and overland flow and sediment do not reach the base of the fan. Controlled flow diversion is recommended upstream of the road to mitigate infrastructure or habitat impacts during very rare (very large) flood events. A comprehensive operation and management approach is presented to achieve sustainable transportation infrastructure and reduce the likelihood of impacts to the sensitive habitat.
Army field training exercises are conducted to replicate real-world combat requirements and are inherently subject to the effects of the prevailing climate and weather conditions. Adapting to variability of climate is part of realistic training and extreme storm events and associated flooding risks can temporarily limit access to training lands and other training features such as water crossings. If an increase in intensity and incidence of extreme precipitation events is realized, installations associated with river systems are likely to have increased flood risk and associated prevention and mitigation costs.Low water crossings (LWCs) are especially susceptible to changes in intensity and incidence of extreme precipitation events with regards to infrastructure usability, resilience, and safety. The June 2, 2016 incident at Fort Hood, TX where five soldiers from the 3rd Battalion, 16th Field Artillery Regiment, 2ndArmored Brigade Combat Team, 1st Cavalry Division drowned when their troop carrier overturned at a flooded LWC, shows the safety risks associated with LWCs.The first objective of this study is to examine the stationary assumption of total annual precipitation, total annual wet days and wet hours, and regional frequency analysis for a range of design storms and extreme events. Both parametric and non-parametric statistical tests were used to detect trends. In addition, precipitation frequency estimates were calculated for the 0.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
