Analysis of Rectangular Side Sluice Gate
(American Society of Civil Engineers, 1993)A side sluice gate is a flow‐regulation device widely used in irrigation works for diverting the flow from a main channel to a secondary channel. The discharge of a side sluice gate may be obtained through the concept of ... -
Agronomic and Environmental Benefits of Water‐Table Management
(American Society of Civil Engineers, 1993)The benefits of water‐table management for increasing crop yields, and reducing nitrate pollution were assessed for the St. Lawrence lowlands region of eastern Canada. Soybeans [ -

Regionalized Partial‐Duration Balanced‐Hydrograph Model
(American Society of Civil Engineers, 1993)For design problems where annual‐event analyses are inappropriate, such as in the case of channel scour due to floods above a threshold, multiple‐event analyses with partial duration series should be used. A procedure for ... -
Estimation and Optimization of Transient Seepage with Free Surface
(American Society of Civil Engineers, 1993)Single sink depths providing maximum ground‐water table decrease during a fixed time interval within a selected area are found for the 2‐D and 3‐D cases. The curve of the maximal phreatic surface position (underflooding ... -
Regional Irrigation Water Demand
(American Society of Civil Engineers, 1993)The study of irrigation water demand has generally been focused at the field level, and the question can be raised as to whether field‐level estimates can be applied successfully to predict the water usage of a region. In ... -
Microsystems Irrigation in Niger, West Africa
(American Society of Civil Engineers, 1993)Small‐scale irrigation plays a crucial role in agricultural production in Niger, West Africa. Despite the prevalence of traditional irrigation microsystems (average size of about 0.1 ha), not much is known about water‐management ... -
Root Growth Simulation Model under Specified Environment
(American Society of Civil Engineers, 1993)Sound irrigation management models require the information of root‐depth development with time in order to determine the active zone of soil reservoir. Development indicates rate of change. Sigmoidal as well as exponential ... -
Closure to “Darcy‐Weisbach Roughness Coefficients for Gravel and Cobble Surface” by John E. Gilley, Eugene R. Kottwitz, and Gary A. Wieman (January/February, 1992, Vol., 118, No. 1)
(American Society of Civil Engineers, 1993) -
Short‐Duration‐Rainfall Intensity Equations for Drainage Design
(American Society of Civil Engineers, 1993)A procedure for developing rainfall intensity‐duration equations for short durations (less than 1 hr) for any location in the United States is described. The procedure uses readily available isopluvial maps developed by ... -
Discussion of “Numerical Modeling of Two‐Dimensional Transient Flow to Ditches” by Saleem Ahmad, Deepak Kashyap, and B. S. Mathur (November/December, 1991, Vol. 117, No. 6)

Use of Landsat Thermal‐IR Data and GIS in Soil Moisture Assessment
(American Society of Civil Engineers, 1993)Landsat satellite Thematic Mapper (TM) data were explored as an alternative for monitoring regional soil moisture conditions. The theoretical method of using single daily temperature data sets to estimate root zone soil ... -

Geochemical Factors Affecting Trace Element Mobility
(American Society of Civil Engineers, 1993)The mobility of trace elements in soil reflects the chemical reactivity of the elements in the soil matrix. The result is that trace‐element mobility is both specie and site dependent. An overview of selected geochemical ... -
Analysis and Design of Trickle‐Irrigation Laterals
(American Society of Civil Engineers, 1993)The problem of a lateral pipe with equally spaced emitters and uniform slope is investigated. Individual emitters are considered in discharge and pressure estimations along the lateral. The friction head loss between ...
