RISComparison of Flood Top Width Predictions Using Surveyed and LiDAR-Derived Channel Geometries
Publisher: American Society of Civil Engineers
Abstract: This paper compares flood top width predictions generated by a one-dimensional flood model using surveyed and light detection and ranging (LiDAR)-based topographic descriptions for varying storm event return intervals. ...
Estimating Watershed-Scale Precipitation by Combining Gauge- and Radar-Derived Observations
Publisher: American Society of Civil Engineers
Abstract: Watershed modeling requires accurate estimates of precipitation; however, in some cases it is necessary to simulate streamflow in a watershed for which there is no precipitation gauge records within close proximity to the ...
Tracking the Cost of Maintaining Stormwater Best-Management Practice Facilities: The Role of Database Design and Data Entry Best Practices
Publisher: ASCE
Abstract: Best-management practices (BMPs) are widely used to mitigate non-point source pollution from stormwater discharges. However, long-term operation and maintenance of stormwater BMPs have been an afterthought before the ...
Characterizing Stormwater Basin Conditions Using Tracked BMP Inspection and Rating Reports from the Virginia Department of Transportation
Publisher: American Society of Civil Engineers
Abstract: Studies have rarely used stormwater best management practice (BMP) condition rating data to quantify changes in condition ratings and characterize condition issues, making it challenging to implement proactive maintenance ...
Condition State–Based Civil Infrastructure Deterioration Model on a Structure System Level
Publisher: American Society of Civil Engineers
Abstract: The successful prediction of civil infrastructure’s deterioration process is crucial for making optimal maintenance, rehabilitation, and replacement (MR&R) decisions under financial constraints. The majority of current ...
Effect of Rain Gauge Proximity on Rainfall Estimation for Problematic Urban Coastal Watersheds in Virginia Beach, Virginia
Publisher: American Society of Civil Engineers
Abstract: In urban areas, it is important to have spatially and temporally dense rainfall measurements for flood modeling, monitoring, and prediction. The objective of this paper is to quantify the effect of rain gauge proximity on ...
Distributed Stormwater Controls for Flood Mitigation within Urbanized Watersheds: Case Study of Rocky Branch Watershed in Columbia, South Carolina
Publisher: American Society of Civil Engineers
Using a Service-Oriented Approach to Simulate Integrated Urban Infrastructure Systems
Publisher: American Society of Civil Engineers
Abstract: This paper explores service-oriented architectures as an approach for simulating integrated urban infrastructure as a system of systems. Models representing three individual infrastructure systems (water, transportation, ...
Quantification of Compound Flooding over Roadway Network during Extreme Events for Planning Emergency Operations
Publisher: ASCE
Abstract: Hurricanes cause substantial inundation of transportation networks, rendering them inaccessible to emergency response vehicles. Because storm tides and heavy rainfall often co-occur during hurricanes, a reliable assessment ...
Quantifying the Impact of Climate Change on Peak Stream Discharge for Watersheds of Varying Sizes in the Coastal Plain of Virginia
Publisher: ASCE
Abstract: Civil infrastructure systems have traditionally been designed assuming stationarity in precipitation. However, climate change is making this assumption invalid, affecting both existing infrastructure designed assuming ...
