Multipoint High-Frequency Sampling System to Gain Deeper Insights on the Fate of Nitrate in Artificially Drained Fields
(ASCE, 1/1/2020 1)The application of high-frequency measurements could potentially enhance current understanding of the hydrology and biogeochemistry of artificially drained agricultural lands. In addition to intensive drainage flow ... -
Pumped Well Drainage System Effects on Mitigating Barrage-Induced Inundation Problems in Low-Lying Plains
(ASCE, 1/1/2020 1)The construction of a new barrage, the Gangjeong–Koryeong Barrage, in the Nakdong River and related sluice-gate operation has resulted in higher river-water and groundwater levels in the floodplain, which has caused the ... -
Practical Silt Fence Design Enhancements for Effective Dewatering and Stability
(ASCE, 1/1/2021)Many of today’s construction sites rely on perimeter control practices to capture and treat sediment-laden stormwater emanating from disturbed lands. Silt fence systems are a common sediment control practice often specified ... -
Water Requirements for Cooling Artificial Turf
(ASCE, 10/1/2020 )Artificial turf with black infill material gained widespread use on athletic fields starting in the early 2000s. One argument made in the desert southwestern United States for replacing natural grass–based athletic fields ... -
Reducing Sediment Deposition on Deflector in Vortex Settling Basins
(ASCE, 10/1/2020 )This paper presents a retrofit for vortex settling basins (VSBs) by perforating the deflector to reduce sediment deposition and thereby lowering VSB failure risks. Experiments were conducted for two retrofitted VSBs with ... -
Comparison of Two Rating Approaches to Monitor Uncontrolled Culverts’ Flows Driven by Small Head Differences
(ASCE, 10/1/2020 )The smallest flows that can be rated using a distributed-type hydraulic rating, which must rely on head- and tailwater stages monitored at local stilling wells, are limited by the combined measurement uncertainty of the ... -
Hybrid Drainage Design for Highway Underpass
(ASCE, 10/1/2020 )Drowning fatalities in traffic accidents often occur at roadway sag curves or depressed sections. An increasing concern is how to quickly and safely remove the stormwater from low points of urban area roadways. In accordance ... -
Modified NRCS Abstraction Method for Flood Hydrograph Generation
(ASCE, 10/1/2021)The Natural Resources Conservation Service (NRCS) abstraction method is based on two main assumptions. The first is that the ratio of actual water retention to maximum potential retention is equal to the ratio of actual ... -
Influence of Cohesion on Scour at Piers Founded in Clay–Sand–Gravel Mixtures
(ASCE, 10/1/2021)An accurate prediction of scour depth around bridge piers is crucial for economical and safe design of bridge pier foundations. The main objective of the present study is to identify the influencing cohesive parameters and ... -
Evapotranspiration and Water Stress Coefficient for Deficit-Irrigated Maize
(ASCE, 10/1/2021)Crop evapotranspiration under deficit soil water conditions must be quantified to accurately manage deficit irrigation and crop water stress and achieve targeted water savings. A stress coefficient is commonly used to ... -
Flow Regimes of a Surcharged Plunging Dropshaft-Tunnel System
(ASCE, 10/1/2021)In drainage and sewerage systems, vertical dropshafts are commonly used to convey water flow from high to low elevations. When the underground tunnel is surcharged, the lower part of the shaft is submerged. The impact of ... -
SILTspread: Performance-Based Approach for the Design and Installation of Silt Fence Sediment Barriers
(ASCE, 10/1/2021)Construction operations are susceptible to high rates of rainfall-induced soil erosion due to the earth-disturbing nature of land-grading activities. Silt fence sediment barriers are a temporary sediment control practice ... -
Approximate Method for Evaluating the Drainage Process of an Urban Pipe Network with Unavailable Data
(ASCE, 10/1/2021)Because drainage network data is unavailable in many urban areas, the accuracy of urban flood simulation may be reduced. A linear reservoir method is proposed to characterize the drainage capacity of a pipe network, and a ... -
Retaining Performance of Four Types of Drainage Ditch on Phosphorus: Field Work
(ASCE, 11/1/2020 )Drainage ditches are effective agricultural facilities because they can drain excess water from the field, and an eco-friendly drainage ditch can also eliminate agricultural nonpoint source pollution effectively. Field ... -
Modeling Solute Transport in the WinSRFR Surface Irrigation Software
(ASCE, 11/1/2020 )A solute transport model has been added to the WinSRFR surface irrigation software package. The model uses advective-dispersive principles to predict the flow of solute with the irrigation stream and its final longitudinal ... -
Evaluating Sensitivity to Clogging by Solid Particles in Irrigation Emitters: Assessment of a Laboratory Protocol
(ASCE, 11/1/2020 )As drip irrigation develops rapidly worldwide, the need for a standardized method to evaluate emitters’ clogging sensitivity is reinforced. Methodologies for evaluating the sensitivity of emitters to clogging enable ... -
Stability Criterion for Uniform Flow in Open Channel Cross Sections with Different Shapes
(ASCE, 11/1/2020 )This paper presents the derivation of an analytical method for identifying the stability of uniform flow in three open channel sections (rectangular, parabolic, and circular). Using a dimensionless relative slope factor, ... -
Prediction of Maximum Scour Depth near Spur Dikes in Uniform Bed Sediment Using Stacked Generalization Ensemble Tree-Based Frameworks
(ASCE, 11/1/2021)The scouring process near spur dikes could jeopardize the stability of riverbanks. Thus, accurate estimation of the maximum scour depth near spur dikes is crucial in river engineering. However, due to the complexity of the ...
