(American Society of Civil Engineers, 2018) -
Simulation-Optimization Model for the Hydraulic and Structural Design of Barrages-Regulators in Egypt
(American Society of Civil Engineers, 2018)With the increasing trend of replacing barrages in Egypt, especially those built before the High Dam in 1971, there is a need to reduce their construction costs. Barrages/regulators are structures used to control water ... -
Closure to “Reynolds-Averaged Navier-Stokes Modeling of Submerged Ogee Weirs” by Øyvind Pedersen, Gábor Fleit, Elena Pummer, Blake P. Tullis, and Nils Rüther
(American Society of Civil Engineers, 2018) -
Exact Solution of Optimum Hydraulic Power-Law Section with General Exponent Parameter
(American Society of Civil Engineers, 2018)Power-law sections provide great flexibility in open channel design. However, in the literature the optimum hydraulic power-law section has been developed for only specific values of the exponent k of the power-law formula. ... -
Closure to “New Theoretical Solution of Stage-Discharge Relationship for Slit Weirs” by Vito Ferro and Ismail Aydin
(American Society of Civil Engineers, 2018) -
Assessing Malcherek’s Outflow Theory to Deduce the Theoretical Stage-Discharge Formula for Overflow Structures
(American Society of Civil Engineers, 2018)New theoretical stage-discharge relationships of different sharp-crested weirs were developed in this study using the new Malcherek’s outflow theory. Although Torricelli’s outflow theory is basically used to estimate the ... -
Canonical Rainfall Distributions in the United States
(American Society of Civil Engineers, 2018)This study identifies five normalized depth-duration functions (NDDFs) that can be used to represent the rainfall characteristics in various regions of the United States. An analysis of the NDDFs at 9,24 hydrometeorological ... -
Treatment of Agriculture Stormwater Runoff by Cascading System of Stormwater Containment Basins
(American Society of Civil Engineers, 2018)A series of four cascading basins were installed at Hambleton Creek Farm in Chestertown, Maryland, to treat agricultural stormwater from a 45.4-ha watershed. The basin system was monitored from July 213 to April 215 for ... -
Modeling Moisture Flow in Root Zone: Identification of Soil Hydraulic and Root Water Uptake Parameters
(American Society of Civil Engineers, 2018)The present study is concerned with the analysis of moisture flow in the crop root zone and estimation of soil hydraulic and root water uptake parameters from soil moisture depletion data using the inverse procedure. The ... -
Predicting Discharge Coefficient of Triangular Side Orifice under Free Flow Conditions
(American Society of Civil Engineers, 2018)Weirs, orifices, baffle sluice gates, and sluice gates are widely used in irrigation networks for distributing water from the source to irrigated areas. Side orifices are generally placed in the side of a channel for ... -
River-Ditch Hydrologic Connections in a Traditionally Irrigated Agricultural Valley in New Mexico
(American Society of Civil Engineers, 2018)Traditional irrigation systems of northern New Mexico are limited by river flow, and thus water scarcity due to drought and population growth menaces their permanence. This study was conducted to examine the relationship ... -
Cotton Responses to Saline Water Irrigation in the Low Plain around the Bohai Sea in China
(American Society of Civil Engineers, 2018)The use of shallow saline groundwater may alleviate the shortage of freshwater resources in the Low Plain around the Bohai Sea in China. The soil salt levels and the responses of cotton seed emergence, growth, and yield ... -
Hydrodynamics of Rectangular Broad-Crested Porous Weirs
(American Society of Civil Engineers, 2018)In this study, the hydrodynamics of rectangular broad-crested porous weirs were numerically simulated using a nonlinear model between the pressure gradient and flow velocity through the porous medium. Computational fluid ... -
Daily Pan Evaporation Estimation Using Heuristic Methods with Gamma Test
(American Society of Civil Engineers, 2018)In this study, radial basis neural network (RBNN), self-organizing map neural network (SOMNN), and multiple linear regression (MLR) are used for the estimation of daily pan evaporation at Pantnagar, situated in the foothills ... -
Comparison of Flooded and Furrow-Irrigated Transplanted Rice (Oryza sativa L.): Farm-Level Perspectives
(American Society of Civil Engineers, 2018)The traditional irrigation methods used in rice cultivation result in a huge quantity of water loss. Exploring ways to produce more rice with less water is essential for food security. A two-season field study was initiated ... -
Comparison of the Performance of ALARM and SEBAL in Estimating the Actual Daily ET from Satellite Data
(American Society of Civil Engineers, 2018)The Analytical Land Atmosphere Radiometer Model (ALARM) has been tested in several countries with observed evapotranspiration (ET) obtained from different ground-based methods, but none from a lysimeter, which is considered ... -
Curve Numbers Seasonal Variation in Mid-Mediterranean Area
(American Society of Civil Engineers, 2018)The curve number (CN) method is a popular technique for estimating a rainstorm event’s direct runoff (Q from its storm depth P). It relies on the parameter CN, a lumped expression of a watershed’s potential hydrologic ... -
Effect of Floating Bridges on Open Channels’ Flow and Bed Morphology
(American Society of Civil Engineers, 2018)Floating bridges are permanent or temporary bridges supported by pontoons. This research was initiated to experimentally study the effect of floating bridges on flow characteristics and bed morphology. Two hundred and ... -
Ventilated Corner Baffles to Assist Upstream Passage of Small-Bodied Fish in Box Culverts
(American Society of Civil Engineers, 2018)Standard box-culvert designs are similar to ancient designs. The acknowledgment of the ecological impact of culverts and road crossings on rivers has led to changes in culvert design guidelines. A small triangular corner ... -
