Soil Salinity Sampling Strategy Using Spatial Modeling Techniques, Remote Sensing, and Field Data
(American Society of Civil Engineers, 2008)The aim of this study was to develop a methodology for collecting soil salinity samples. The objectives of this paper are to: (1) estimate the number of soil salinity samples needed to capture the variability in the soil ... -
Upland Erosion Modeling in a Semihumid Environment via the Water Erosion Prediction Project Model
(American Society of Civil Engineers, 2008)The major water quality impairment in the midwest United States is sediment eroded from agricultural lands. Yet, few understand the spatial and temporal variability of erosion, or soil erosion dynamics, in relation to ... -
Quick Method for Estimating Furrow Infiltration
(American Society of Civil Engineers, 2008)This paper presents a simple and quick method for estimating furrow infiltration using a single advance point based on the volume balance equation. The furrow infiltration and water front advance along the furrow are assumed ... -
Static and Dynamic Data Reconciliation for an Irrigation Canal
(American Society of Civil Engineers, 2008)This paper deals with the problem of fault detection and isolation in irrigation canals. We have developed a method which combines static and dynamic data reconciliation for the validation of measurements, detection, and ... -
Evaluation of a Genetic Algorithm for the Irrigation Scheduling Problem
(American Society of Civil Engineers, 2008)A typical irrigation scheduling problem is one of preparing a schedule to service a group of outlets which may be serviced simultaneously. This problem has an analogy with the classical earliness/tardiness problem in ... -
Contribution of Evapotranspiration Reduction during Sprinkler Irrigation to Application Efficiency
(American Society of Civil Engineers, 2008)The effect of reduced corn evapotranspiration (ET) during solid-set sprinkler irrigation on application efficiency was analyzed on two subplots. During each irrigation event, one subplot was irrigated ( -
Development of a Hydro-Salinity Simulation Model for Colorado’s Arkansas Valley
(American Society of Civil Engineers, 2008)A model to calculate the quantity and quality of river flows by simulating hydro-chemical processes in soil and the spatial/temporal distribution of irrigation return flows is introduced. By simulating the hydro-chemical ... -
Drainage of Ponded Surface by an Array of Ditches
(American Society of Civil Engineers, 2008)A comprehensive analytical solution for the quantity of seepage into an array of fully penetrating ditches from a ponded surface has been obtained using hodograph and Schwarz–Christoffel transformation. The solution includes ... -
Performance Study of SPAW Model with Temperature-Derived ET0 as Input in Place of Pan Evaporation under Wheat Crop in a Semiarid Subtropical Climate
(American Society of Civil Engineers, 2008)In this study, we have attempted to enhance the utility of soil–plant–atmosphere–water (SPAW) model that has been used successfully by various workers in different countries for soil moisture prediction under different ... -
Evaluation of a Method for Estimating Irrigated Crop-Evapotranspiration Coefficients from Remotely Sensed Data in Idaho
(American Society of Civil Engineers, 2008)Hydrologic modeling and agricultural water consumption analyses typically require some estimation of expected evapotranspiration (ET) from any given land cover or crop type. The main parameter used to make such estimations ... -
Permeable Pavement as a Hydraulic and Filtration Interface for Urban Drainage
(American Society of Civil Engineers, 2008)Permeable pavement, specifically cementitious permeable pavement (CPP), is a passive structural low impact development material and green infrastructure system for rainfall-runoff control. Multifunctional engineered CPP ... -
Reference and Crop Evapotranspiration in South Central Nebraska. II: Measurement and Estimation of Actual Evapotranspiration for Corn
(American Society of Civil Engineers, 2008)In planning, designing, and managing of surface and groundwater supply, it is essential to accurately quantify actual evapotranspiration -
Surface Renewal Estimation of Pasture Evapotranspiration
(American Society of Civil Engineers, 2008)Experiments to measure the evapotranspiration of an improved, irrigated pasture were conducted at the University of California, Davis, CA field station and over a commercial irrigated pasture on Twitchell Island in the ... -
Infiltration Capacity Assessment of Urban Pavements Using the LCS Permeameter and the CP Infiltrometer
(American Society of Civil Engineers, 2008)This paper presents the Cantabrian portable infiltrometer (CP infiltrometer), a specially designed device based on rainfall simulation for the assessment of the infiltration capacity of all types of urban pavements. Several ... -
Effects of Lime Amendment on the pH of Engineered Soil Mix for the Purposes of Bioretention
(American Society of Civil Engineers, 2008)Storm-water management strategies increasingly focus on the implementation of infiltration-based best management practices (BMPs) such as swales, bioretention basins, and rain gardens. The surface vegetation and underlying ... -
Surface Energy Balance-Based Model for Estimating Evapotranspiration Taking into Account Spatial Variability in Weather
(American Society of Civil Engineers, 2008)Reliable estimates of evapotranspiration (ET) from vegetation are needed for many types of water-resource investigations. How well models can estimate ET from vegetation varies, depending on the capabilities of the model ... -
Reference and Crop Evapotranspiration in South Central Nebraska. I: Comparison and Analysis of Grass and Alfalfa-Reference Evapotranspiration
(American Society of Civil Engineers, 2008)In Nebraska, historically, there have been differences among the water regulatory agencies in terms of the methods used to compute reference evapotranspiration -
Compaction’s Impacts on Urban Storm-Water Infiltration
(American Society of Civil Engineers, 2008)Soil infiltration is a critical component of most urban runoff models. However, it has been well documented that, during urbanization, soils are greatly modified, especially in relation to soil density. Increased soil ... -
Sorptive Media Biofiltration for Inorganic Nitrogen Removal from Storm Water
(American Society of Civil Engineers, 2008)Passive biological filtration for nitrate removal from storm-water drainage is challenged by highly transient mass loadings, the need to adequately supply an electron donor, and potential inhibition by dissolved oxygen ... -
Multiyear and Seasonal Variation of Infiltration from Storm-Water Best Management Practices
