Evaluation of Catchment-Scale Stormwater Runoff Management on First-Flush Water Quality and Storm Discharge Quantity
(2018-12)
Urbanization and resulting imperviousness has caused increased pollutant loadings into receiving water bodies. One of the main sources of pollutant loads is stormwater runoff. The purpose of this study was to investigate ...
Making Satellite Sensors Better for Hydroclimatic Applications: Evaluation of NASA SMAP Soil Moisture Using Oklahoma’s Environmental Monitoring Network—MESONET
(2017-12-15)
Soil moisture, quantified as the ratio of liquid water to soil in volume or weight, is the measurement of the water that is held in the space between soil particles. Understanding the components of soil, particularly its ...
Method of Rehabilitation for Corrosion Damage in The End Region of Prestressed Concrete Bridge Girders
(2021-12-17)
Two of important factors in longevity of prestressed concrete bridge girder are the effect of corrosion to prestressing reinforcement in concrete and process of stress transferring from prestressing strands to concrete. ...
Impact of Soil pH on the Leaching Rate of Disposed Li-ion Batteries
(2021-05-14)
Lithium-ion batteries (LIB) are becoming the front-runner for rechargeable battery usage yet are rarely disposed of properly. Analysis of varying landfills and electronic waste recycling centers throughout the world show ...
Evaluation of long-term performance of in-stream channel stability structures for protecting Oklahoma bridges and roads
(2021-08)
Streambank erosion can damage bridges, hydraulic structures, and private property. In-stream structures may be installed to control river migration and limit bank erosion during large precipitation events. Historically, ...
Evaluation of Durability and Corrosion Behavior of Ultra-High Performance Concrete for use in Bridge Connections and Repair
(2019-08-01)
Ultra-high performance concrete (UHPC) is one of the new, cutting edge concepts in the world of concrete. Boasting significantly higher compressive and tensile strengths, longer service life, and significantly increased ...
End Regions Repair of Prestressed Girders for Restoring the Shear Capacity Using UHPC, FR-SCC, and MALP
(2021)
One of the most important concepts in prestressed concrete is stress transfer from prestressing strands to the surrounding concrete. The efficiency of this process dictates the overall quality of the structural member, ...
The Effect of Pore Water Evaporation on Transport of Caffeine, Propranolol, and Ciprofloxacin: A Sand Column Study and Model Simulation
(2016-12)
The purpose of this study was to explore the transport of selected pharmaceuticals under saturated and unsaturated conditions, simulating environmental processes of evaporation and flooding. Caffeine (a stimulant), ...
Remote Sensing of Hydrologic Variables in Rivers
(2020)
The use of a “rating curve”, an empirical relationship between water depth in a river and the volumetric flux of water, or discharge, is subjected to uncertainty in data extrapolation, complexity due to changes in channel ...
Application of basalt fiber reinforced polymer rebar for prestressed concrete beams
(2022-08)
All steel reinforced concrete infrastructure that is facing a chemical environment and
corrosion will have their service life greatly reduced. With time it will lead to a premature and an
inevitable failure of the steel ...
