Updated Canonical Rainfall Distributions in the United States
(ASCE, 12/1/2020 )Previous research has identified five canonical rainfall distributions in the United States; however, identification of these rainfall distributions did not include any rainfall data in the state of Texas. In this study, ... -
Scour around Double-Winged Log Frames under Clear Water Condition
(ASCE, 12/1/2020 )In-stream low-head hydraulic structures are eco-friendly solutions to maintain the natural aquatic ecosystems. This study focused on scour characteristics around double-winged log -frames under different hydraulic conditions ... -
Asymmetrical Wall Baffles to Assist Upstream Fish Passage in Box Culvert: Physical Modeling
(ASCE, 12/1/2020 )Although waterway connectivity is a requirement for all freshwater fish, culverts have had negative impacts on freshwater river ecology. Following a recent biological study suggesting that asymmetrical wall baffles may be ... -
Analytical Steady-State Solution for a Three-Dimensional Partially Penetrating Ditch Drainage System Receiving Water from an Uneven Ponding Field
(ASCE, 12/1/2020 )A steady-state analytical solution is proposed for computing three-dimensional seepage into a partially penetrating ditch drainage system receiving water from an uneven ponding field of finite size. The draining soil is ... -
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, ... -
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 the Hydromechanical Solution for Maintaining Fish Migration Continuity at Coastal Structures
(ASCE, 12/1/2020 )To promote water control in coastal areas developed for agriculture, tidal hydraulic structures (doors and flap gates) are used for the hydraulic management of irrigation and drainage networks. By closing when the water ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Skimming Properties of Sharp-Crested Weirs
(ASCE, 9/1/2020 1)Weirs are structures that allow uppermost layers of liquids to flow by gravity downstream. They are, therefore, inherently gravity skimmers, and have successfully been used as skimmers in numerous applications, including ... -
Cylindrical Central Baffle Flume for Flow Measurements in Open Channels
(ASCE, 9/1/2020 1)This work experimentally investigated a modified venturi flume formed by placing portable cylinders vertically upright in trapezoidal channels, referred to herein as the cylindrical central baffle flume (CCBF). This mobile ... -
Local Energy Losses for Wave-Type Flows at Abrupt Bottom Changes
(ASCE, 9/1/2020 1)Low-head hydraulic structures, like weirs or barrages, are constructed on rivers for irrigation or power-generation purposes. As the upstream water level rises due to these structures, it is necessary to build an ... -
Application of Hybrid Flow Data and Dimensional Analysis to Gated-Culvert Flow Estimation
(ASCE, 9/1/2020 1)A calibrated flow rating equation is often used to determine the flow rate through a hydraulic structure as a convenient and relatively inexpensive method to avoid the difficulties of direct discharge measurements in an ... -
Comparing Fuzzy SARSA Learning and Ant Colony Optimization Algorithms in Water Delivery Scheduling under Water Shortage Conditions
(ASCE, 9/1/2020 1)Water delivery scheduling was investigated in this study using fuzzy state, action, reward, state, action (SARSA) learning (FSL) and ant colony optimization (ACO) methods to find the advantages of a new robust model (FSL) ... -
GIS-Based Python Simulation of Infiltration over a Landscape
