Closure to “Method for Quantifying Freshwater Input and Flushing Time in Estuaries” by Qizhong Guo and George P. Lordi
Publisher: American Society of Civil Engineers
Applicability of Criterion for Onset of River Ice Breakup
Publisher: American Society of Civil Engineers
Abstract: The breakup of an ice cover may lead to ice jamming. However, tested methods for predicting the ice cover breakup are lacking. One method uses hinge resistance at riverbanks as a tentative criterion for ice cover breakup ...
Closure to “Gate and Vacuum Flushing of Sewer Sediment: Laboratory Testing” by Qizhong Guo, Chi-Yuan Fan, Ramjee Raghaven, and Richard Field
Publisher: American Society of Civil Engineers
Sediment and Heavy Metal Accumulation in Dry Storm Water Detention Basin
Publisher: American Society of Civil Engineers
Abstract: Amount, heavy metal content, organic content, and mass distribution of the bottom sediment in an 18 year old, single-purpose dry storm water detention basin were measured. The measured results were used to assess the effect ...
Removal of Salt Marsh–Impairing Tidal Flow Restrictions: Impact on Upstream Flooding under the Combined Influence of Rainfall and Tide
Publisher: ASCE
Abstract: Restoring tidal flow to anthropogenically flow-restricted waterways provides ecological benefits while also changing the flood risk of adjacent lands. Our research evaluated the flooding risk on Tremley in Linden, New ...
Angular Velocity Formula for Turbulent Vortex Chamber Flows
Publisher: American Society of Civil Engineers
Abstract: Vortex separators are increasingly utilized to remove suspended solids from stormwater runoff. Understanding flow patterns in a confined vortex chamber is crucial when investigating the mechanisms of liquid-solid separation. ...
Drainage Alternatives for Rain Gardens on Subsoil of Low Permeability: Balance among Ponding Time, Soil Moisture, and Runoff Reduction
Publisher: ASCE
Abstract: Rain gardens are commonly used as green infrastructure to reduce runoff volume and introduce ecological benefits to urban areas. The objective of this study was to evaluate hydrologic performance of a rain garden constructed ...
Method for Quantifying Freshwater Input and Flushing Time in Estuaries
Publisher: American Society of Civil Engineers
Abstract: A method is developed to quantify total freshwater input and flushing time in estuaries using measured flow and salinity data at the estuary-ocean boundary. A formula is derived to calculate the volume of mixed estuarine ...
Surging in Urban Storm Drainage Systems
Publisher: American Society of Civil Engineers
Abstract: The existence of surge and related problems, namely, sharp‐peaked overflows, manhole, or drop‐shaft cover blow‐off; waterjets into the atmosphere (geysers); and structural damages in urban storm drainage systems, are ...
Laboratory Scale Study to Quantify the Effect of Sediment Accumulation on the Hydraulic Conductivity of Pervious Concrete
Publisher: American Society of Civil Engineers
Abstract: Pervious concrete systems can reduce storm water runoff, minimize non-point-source pollution, and increase groundwater recharge. However, pervious concrete has the potential to clog, reducing its infiltration rate enough ...
