Closure to “<i>Conjunctive Use—Advantages, Constraints, and Examples</i>” by Jack J. Coe (May/June, 1990, Volume 116, No. 3)
(American Society of Civil Engineers, 1992) -
Closure to “<i>Rating Correction for Lateral Settlement of Parshall Flumes</i>” by Steven R. Abt and Kenneth J. Staker (November/December, 1990, Vol. 116, No. 6)
(American Society of Civil Engineers, 1992) -
Decision Support System for Crop Planning during Droughts
(American Society of Civil Engineers, 1992)Demand for water is increasing continually, whereas available supplies are more or less constant. Under these circumstances there is an urgent need to introduce efficient techniques in water resources management for optimal ... -
Modeling Shallow Overland Flow in Surface Irrigation
(American Society of Civil Engineers, 1992)Based on a literature review, the suitability of the Manning equation to represent shallow flow in surface irrigation is questioned. This conclusion is supported by analysis of both experimental data of the present study ... -
Adaptation of Horton and SCS Infiltration Equations to Complex Storms
(American Society of Civil Engineers, 1992)Two equations commonly used for estimating and modeling infiltration from pervious land surfaces are those developed by Horton and the U.S. Soil Conservation Service (SCS). The main shortcoming of the Horton equation is ... -
Movement of Nonpoint‐Source Contaminants through Heterogeneous Soils
(American Society of Civil Engineers, 1992)Due to the widespread use of ground water as a supply of drinking water in the United States, predicting the effect that nonpoint sources of contamination have on the quality of nearby ground‐water supplies is an important ... -
Field‐Measured Hydraulic Resistance Characteristics in Vegetation‐Infested Canals
(American Society of Civil Engineers, 1992)Realistic estimates of hydraulic resistance are essential to the proper design and analysis of irrigation canal networks. Extensive field studies in Egypt provide data on the magnitude and variability of hydraulic resistance ... -
Sluice‐Gate Discharge Equations
(American Society of Civil Engineers, 1992)Sluice‐gate discharge coefficient is an involved function of geometric and hydraulic parameters. For free flow, it is related to upstream depth and gate opening, whereas for submerged flow, in addition to these parameters, ... -
Hydrologic Model for Drained Forest Watershed
(American Society of Civil Engineers, 1992)Modeling the hydrology of a forest watershed is helpful to understand the interaction of the hydrologic components and the effects of management activities on the performance of the system. This study was conducted to ... -
Design of Trapezoidal Expansive Transitions
(American Society of Civil Engineers, 1992)Open‐channel expansions for subcritical flows are encountered in the design of hydraulic structures such as aqueducts, superpassages, and so on. In these structures the flow tends to separate while subjected to the positive ... -
Optimization Model for Alternative Use of Different Quality Irrigation Waters
(American Society of Civil Engineers, 1992)A linear programming model was developed to optimize the use of different quality waters by alternative irrigations rather than by blending. In a situation of poor‐quality ground water and limited good‐quality canal water, ... -
Interpretation of Kostiakov Infiltration Parameters for Borders
(American Society of Civil Engineers, 1992)The relationship between Kostiakov and modified Kostiakov infiltration parameters and the parameters of several other infiltration equations are analyzed and discussed from a theoretical and practical point of view. Kostiakov ... -
Modeling Irrigation Schedules for Lowland Rice with Stochastic Rainfall
(American Society of Civil Engineers, 1992)A procedure is presented to estimate probabilistic irrigation requirements for lowland rice cultivation. The procedure uses a water‐balance equation in which rainfall and evapotranspiration are considered as stochastic ... -
Erratum: “Normal‐Depth Calculations in Complex Channel Sections” by Edward D. Shirley and Vicente L. Lopes (March/April, 1991, Vol. 117, No. 2)
(American Society of Civil Engineers, 1992) -
Constant Hole‐Spacing Trail Tubes
(American Society of Civil Engineers, 1992)Low‐pressure irrigation systems are developed to reduce energy requirement and cost. A consequence of low pressure is a reduced sprinkler wetting coverage. Small wetting coverages cause high water application rates and ... -
Equivalent Kostiakov Parameters for SCS Infiltration Families
(American Society of Civil Engineers, 1992)A method for obtaining the Kostiakov equation parameters for the different U.S. Soil Conservation Service (SCS) infiltration families is given along with the results. The deviation functional integrated over period of time ... -
Erratum: “Furrow Geometric Parameters” by Thomas J. Trout (September/October, 1991, Vol. 117, No. 5)
(American Society of Civil Engineers, 1992) -
Rainfall Area Identification Using GOES Satellite Data
(American Society of Civil Engineers, 1992)Geostationary operational environmental satellite (GOES) infrared (IR) images and rain gauge measurements are used to study five convective storm events in Florida. The study region is divided into a training area and a ... -
Surface and Subsurface Drainage of Metropolitan City in Arid Zone
(American Society of Civil Engineers, 1992)Qualitative and quantitative aspects of both the surface and subsurface drainage in the city of Riyadh, in the Kingdom of Saudi Arabia, are studied with a view to (1) Determining the resuse potential; and (2) estimating ... -
