Comparison of One- and Two-Dimensional Models to Simulate Alternate and Conventional Furrow Fertigation
(American Society of Civil Engineers, 2012)Simulation models have recently been used in many studies for simulation of water flow and solute transport in soil under different irrigation systems. The objective of this study was to compare the HYDRUS-1D and HYDRUS-2D ... -
New Solution Method for Water Surface Profile along a Side Weir in a Circular Channel
(American Society of Civil Engineers, 2012)Side weirs are commonly installed along the sides of open channels. Computation of water surface depth over side weirs is essential to determine their discharge. Analytical solutions for water surface profiles along a ... -
Estimating Water Requirements of an Irrigated Mediterranean Vineyard Using a Satellite-Based Approach
(American Society of Civil Engineers, 2012)Quantification of evapotranspiration (ET) is a key factor to design management strategies for improving water use efficiency of irrigated viticulture. In the study, an integrated approach of crop coefficients derived from ... -
Closure to “Simple Method for the Design of Microirrigation Paired Laterals on Sloped Fields” by Shufang Jiang and Yaohu Kang
(American Society of Civil Engineers, 2012) -
Quadrangle Downscaling of Global Climate Models and Application to Riyadh
(American Society of Civil Engineers, 2012)Climate change impact reports by the Intergovernmental Panel on Climate Change (IPCC) are well established throughout the world. By now many local, regional, and central authorities are aware of these impacts and they try ... -
Standardization of Reference Evapotranspiration Models for a Subhumid Valley Rangeland in the Eastern Himalayas
(American Society of Civil Engineers, 2012)For efficient irrigation water management and hydro-meteorological studies at both the field and catchment scales, a need exists to evaluate the existing evapotranspiration (ET) estimation methods under varied physiographical ... -
Closure to “Most Hydraulically Efficient Riprap-Lined Drainage Channels” by David C. Froehlich
(American Society of Civil Engineers, 2012) -
Urban Weather Data to Estimate Reference Evapotranspiration for Rural Irrigation Management
(American Society of Civil Engineers, 2012)Weather data measured in urban areas are generally more easily available than those in rural areas. If the urban weather data are used to calculate the reference crop evapotranspiration ( -
Study on the Accelerated Life Test for Durability of Irrigation Microsprayer
(American Society of Civil Engineers, 2012)The test time, the time the failure occurred, and the service life of microsprayers of accelerated life tests are analyzed and compared with those of normal life tests on the basis of the life distribution and parameters ... -
Model for Nonlinear Root Water Uptake Parameter
(American Society of Civil Engineers, 2012)An empirical relationship is developed for the nonlinear root water uptake parameter in the O-R moisture uptake model from easily measurable plant physiological parameters, such as maximum daily transpiration, maximum root ... -

VIPMET: New Real-Time Data Filtering–Based Automatic Agricultural Weather Station
(American Society of Civil Engineers, 2012)Agricultural weather stations are normally utilized to register weather variables (e.g., temperature, relative air humidity, solar radiation and wind speed). These data can be used to estimate daily and hourly reference ... -
Piano Key Weir: Reservoir versus Channel Application
(American Society of Civil Engineers, 2012)The piano key (PK) weir is a relatively new nonlinear weir geometry that can be used to increase spillway discharge capacity over linear weir geometries, particularly when the weir footprint area is restricted (e.g., spillways ... -
Effect of the Capillary Fringe on Steady-State Water Tables in Drained Lands
(American Society of Civil Engineers, 2012)When the flow in the capillary fringe above the water table is taken into account in land-drainage theory, water-table heights are lower than those predicted when incident rainfall on the surface is assumed to travel ...
