Optimal Water Allocation under Deficit Irrigation in the Context of Colorado Water Law
(American Society of Civil Engineers, 2019)The common belief is that there are opportunities in the agricultural sector to use less irrigation water and thus make saved water available for municipal and industrial uses. The key is for farmers to maximize farm profit ... -
Response of Taro to Varying Water Regimes and Soil Textures
(American Society of Civil Engineers, 2019)Taro [Colocasia esculenta (L.) Schott] is a major root crop widely distributed in the tropics and subtropics. However, little information is available on its water stress tolerance under different soil textures. Therefore, ... -
Validation of Dripline Emitter Characteristics and Pump Performance Curve for Network Analysis
(American Society of Civil Engineers, 2019)In this paper, simple methods for validating the emitter characteristics of driplines and pump performance curves for dripline network design and simulation are presented. Pressure compensating driplines were tested and ... -
Supercritical Stormwater Flow Interception through Bottom Rack with Transverse Barrier
(American Society of Civil Engineers, 2019)The Hong Kong West Drainage Tunnel (HKWDT) system consists of 34 stormwater intake structures designed to intercept stormwater runoff in upland catchments. During stormwater events, each of these intake structures intercepts ... -
Water Table Fluctuation from Green Infrastructure Sidewalk Planters in Philadelphia
(American Society of Civil Engineers, 2019)Popularity of infiltration-based green infrastructure (GI) has spurred concern about rising groundwater tables and the potential detrimental effect on building foundations. This study examines water table fluctuations ... -
Experimental Study of Central Baffle Flume
(American Society of Civil Engineers, 2019)In this paper, the hydraulics of a central baffle flume (CBF) were experimentally studied. Extensive experimental runs were carried out to highlight the effects of different geometrical parameters such as baffle length, ... -
Using Vanes to Reduce Flow Separation and Head Loss in Warped Transition
(American Society of Civil Engineers, 2019)Irrigation and water-supply systems commonly need channel transitions to provide changes of channel section. Warped transition (WT) is an option for transitioning from a narrow rectangular channel to a wide trapezoidal ... -
Spatiotemporal Magnitudes and Trends of Cover-Crop Evapotranspiration in Nebraska, Iowa, and Kansas
(American Society of Civil Engineers, 2019)Although some benefits of growing cover crops have been recognized in agricultural production fields, wider adoption of these rotational crops requires quantitative information on actual evapotranspiration (ETa) in different ... -
Variability of Furrow Infiltration and Estimated Infiltration Parameters in a Macroporous Soil
(American Society of Civil Engineers, 2019)Understanding the spatial and temporal variations of infiltration in furrows is essential for the design and management of furrow irrigation systems. A key difficulty in quantifying the process is that infiltration depends ... -
Relationships between MDS, Soil, and Weather Variables for Topaz Apple Tree Cultivated in Coarse-Textured Soils
(American Society of Civil Engineers, 2019)The purpose of this paper is to test the hypothesis of the existence and strength of relationships between maximum trunk daily shrinkage (MDS), soil matric potential (SMP) at various soil depths, and some weather variables ... -
Water-Use Efficiency of Potted Pakchoi in Yunnan Laterite with Root Infiltration Irrigation and Anticlogging Emitter
(American Society of Civil Engineers, 2019)A method is developed to calculate crop water consumption based on the water balance principle. An independently designed emitter resistant to clogging caused by negative pressure (EK) is also evaluated. The water-use ... -
Effects of Slope Magnitude and Length on SWAT Baseflow Estimation
(American Society of Civil Engineers, 2019)The aim of this study was to improve streamflow predictability using the soil and water assessment tool (SWAT) model for baseflow estimation in a steeply sloped watershed. The two objectives were (1) to appraise ... -
Impact of Air Temperature and Relative Humidity Measured over Rice and Grass Canopies on Penman-Monteith Reference Evapotranspiration Estimates
(American Society of Civil Engineers, 2019)The adoption of the Penman-Monteith reference evapotranspiration (ETo) method necessitates the use of climatic data and parameters measured above a reference surface (e.g., reference grass), which is rarely available ... -
Numerical Comparison between Iterative and Noniterative Coupled Simulations for Surface Water Flow and Solute Transport with Unstructured Grid in Two-Dimensional Basin Fertigation
(American Society of Civil Engineers, 2019)Two-dimensional shallow water and advection-dispersion equations were applied to describe the surface water and solute transport processes in basin fertigation. Then the fully implicit temporal solution was constructed for ... -
Effect of Meter Orientation Downstream of a Short Radius Elbow on Electromagnetic Flow Meters
(American Society of Civil Engineers, 2019)Electromagnetic flow meters (known as magnetic flow meters) are a widely used type of flow meter. This study examines the performance of magnetic flow meters when the electrodes in the meter are positioned at two different ... -
