Closure to “<i>Response of Muskingum Equation to Step Input</i>” by Mohammad Akram Gill (August, 1989, Vol. 115, No. 4)
(American Society of Civil Engineers, 1991) -
Closure to “<i>Systems Analysis of Tank Irrigation: I. Crop Staggering</i>” by S. G. Mayya and Rama Prasad (June, 1989, Vol. 115, No. 3)
(American Society of Civil Engineers, 1991) -
Hydraulic Characteristics of Circular Flume
(American Society of Civil Engineers, 1991)Laboratory experiments are conducted to evaluate the hydraulic characteristics of several circular flumes. The circular flume is a simple and low‐cost water measuring device constructed from two pieces of pipes, one installed ... -
Field Study on Irrigation Delivery Performance
(American Society of Civil Engineers, 1991)Farmers who receive water from irrigation districts prefer deliveries that are flexible but accurate in frequency, rate, and duration. To study how well an irrigation district was able to match deliveries to farmers' orders ... -
Measurement of Irrigation Flows through Irrigation Turnouts
(American Society of Civil Engineers, 1991)Accurate measurement of applied water volumes in surface irrigation fields is important towards improving irrigation efficiencies and management of the surface irrigation system. In flood irrigated fields, applied water ... -
Discussion of “<i>Systems Analysis of Tank Irrigation: I. Crop Staggering</i>” by S. G. Mayya and Rama Prasad (June, 1989, Vol. 115, No. 3)
(American Society of Civil Engineers, 1991) -
Direct Solution to Surface Irrigation Advance Inverse Problem
(American Society of Civil Engineers, 1991)A modification to the double‐sweep routine commonly used to solve the continuity and momentum equations for surface irrigation models has been developed to allow the solution of one global parameter at each time step. ... -
NOAA Polar‐Orbiting Satellite APT Data in Lake Evaporation Estimation
(American Society of Civil Engineers, 1991)Water surface temperatures of Lake Okeechobee are measured using automatic picture transmission (APT) thermal infrared data from the National Oceanic and Atmospheric Administration (NOAA) polar‐orbit satellite advanced ... -
Testing of Soil Moisture Prediction Model for Army Land Managers
(American Society of Civil Engineers, 1991)The ARC/INFO geographic information system (GIS) has been combined with the ARX spatial expert system and the SMSP soil moisture‐soil strength model to give the managers of a major Australian army training base the ability ... -
Setting Time Effects on Bentonite Water‐Well Annulus Seals
(American Society of Civil Engineers, 1991)Shear strength tests are conducted in a model of a water, well on four, commercially available, granular bentonite well sealing products. The time dependency of annulus seal shear strength and resistance to piping is ... -
Nitrate Leaching under Irrigation on Coastal Plain Soil
(American Society of Civil Engineers, 1991)The effect of irrigation and nitrogen management on ground‐water quality was evaluated for four years on a Sassafras sandy loam Coastal Plain soil. Applying the greatest portion of the nitrogen by side‐dressing and by ... -
Roughness Coefficients for Selected Residue Materials
(American Society of Civil Engineers, 1991)Analysis of surface runoff on upland areas requires identification of roughness coefficients. A laboratory study is conducted to measure Darcy‐Weisbach and Manning roughness coefficients for corn, cotton, peanut, pine ... -
Discharge Coefficient of Lateral Diversion from Trapezoidal Channel
(American Society of Civil Engineers, 1991)The discharge coefficient of a lateral opening in a prismatic trapezoidal main channel is determined for subcritical flow conditions from considerations of the conservation of energy and the conservation of momentum. The ... -
Vertical Leakage in Egypt's Nile Valleys Estimation and Implications
(American Society of Civil Engineers, 1991)The determination of vertical ground‐water leakage is particularly important for irrigated agriculture where adequate drainage is required to prevent high water tables and related problems of salt buildup and waterlogging. ... -
Simulation of Supplemental Irrigation from On‐Farm Ponds
(American Society of Civil Engineers, 1991)Several researchers have shown that on‐farm runoff collection and supplemental irrigation systems can increase and stabilize crop production in many regions of the world. The objective of this study is to develop simulation ... -
Local Scour Downstream of Box‐Culvert Outlets
(American Society of Civil Engineers, 1991)This laboratory study investigates the local scouring phenomenon in sand that occurs downstream of box culverts. Although culvert hydraulics can include special cases, such as culverts on hydraulically steep slopes for ... -
Projectwide Water‐Order Scheduling by Computer
(American Society of Civil Engineers, 1991)A computerized water ordering system is developed to quickly determine the distribution of the water demands for an irrigation water delivery system. The inputs required for the program are water‐order requests by system ... -
