1. Field and Laboratory Studies of Acid Sulfate Soils
(American Society of Civil Engineers, 2002)Drains are introduced into acid sulfate (AS) soils grown to sugar cane to prevent waterlogging and drain runoff water. Drains have the potential to promote deleterious reactions and facilitate the transport of the resulting ... -
1‐D, 2‐D, and 3‐D Infiltration for Irrigation
(American Society of Civil Engineers, 1987)Models for one‐, two‐, and three‐dimensional infiltration for irrigation are derived using an energy equation and Darcy's law. The models were verified with Fok and Chiang's (4) experimental data. A good agreement is found ... -
2. Numerical Simulations of Water Flow and Solute Transport Applied to Acid Sulfate Soils
(American Society of Civil Engineers, 2002)Field investigations of Rassam et al. in 2001 have highlighted the effects of infiltration, drainage, and evapotranspiration on the dynamics of water flow and solute transport in acid sulfate (AS) soils. In this work, -

2‐D Infiltration Equations for Furrow Irrigation
(American Society of Civil Engineers, 1984)Two‐dimensional (2‐D) infiltration equations for furrow irrigation expressed in explicit algebraic forms are developed and based on four consecutive time intervals which were derived in a previous study (1). From another ... -
3D Numerical Simulations of the Bed Evolution at an Open-Channel Junction in Flood Conditions
(American Society of Civil Engineers, 2024)Open-channel junctions pose a risk associated with flooding and erosion. However, despite the numerous studies concerning the channel junctions, the bed and flow field evolutions at junctions for flood conditions have yet ... -
3D Numerical Study of Scour around a Pile Group in the Staggered Arrangement under Combined Wave-Current Flows
(ASCE, 2024/04/01)The paper presents three-dimensional (3D) simulations conducted to study scour around a pair of twin piles arranged in different skew angle (α) configurations under combined wave-current flow conditions, utilizing a ... -
A New Method for Evaluating the Technical Efficiency of Irrigation and Drainage Networks Using LRDEA and Three-Step Monte Carlo Simulation
(ASCE, 2024/02/01)Investigating the efficiency of irrigation networks is one of the most crucial factors in providing the information needed to improve the efficiency of these systems. Due to the recent water crisis in Iran, it should be ... -
A Numerical Method for Cross-Section Changes and Gates Resulting from the Riemann Problem in Irrigation Canal Systems
(ASCE, 2024/02/01)Hydraulic simulation models offer unlimited opportunities for improving the performance of irrigation canal systems by studying the flow behavior in a large and complex canal network under a variety of design and management ... -
A Paradigm Shift in Irrigation Management
(American Society of Civil Engineers, 2002)In coming decades, irrigated agriculture will be called upon to produce up to two thirds of the increased food supply needed by an expanding world population. But the increasing dependence on irrigation will coincide with ... -
A Penman for All Seasons
(American Society of Civil Engineers, 1986)Ten forms of the Penman combination evapotranspiration equation are reviewed and compared with lysimeter estimates at three locations. Aerodynamic and canopy resistance forms by Monteith and Thom and Oliver and an empirical ... -
A Priori Identifiability of Unsaturated Soil Parameters
(American Society of Civil Engineers, 2000)A priori identifiability (i.e., identifiability under perfect data) is a necessary condition for posteriori identifiability (i.e., identifiability under real data), and by implication a priori nonidentifiability is a ... -
A Real-Time Refined Roughness Estimation Framework for the Digital Twin Model Calibration of Irrigation Canal Systems
(ASCE, 2024/02/01)Digital twin (DT) models can mirror irrigation canal systems and monitor the hydrodynamic processes in real-time to help create scheduling schemes. As for the DT model of the open channel, an important parameter that needs ... -
A Reformed Empirical Equation for the Discharge Coefficient of Free-Flowing Type-A Piano Key Weirs
(American Society of Civil Engineers, 2023/04/01)The existing equations for the discharge coefficient of Piano key weirs (PKWs) use a limited range of experimental data, which means that they are inappropriate for wide parametric ranges that might lead to significant ... -
A Review of Literature on the Scour Process under Different Jets Conditions
(ASCE, 7/21/2023 )Scour is a natural phenomenon in alluvial streams around hydraulic structures due to the removal of bed material and often leads to their failure. Scour due to jets are the most prevalent form of scour seen downstream of ... -
A Semicoupled Shallow-Water Model for Vertical Velocity Distribution in an Open Channel with Submerged Flexible Vegetation
(ASCE, 2022/09/01)This study detailed a novel semicoupled method for estimating the three-dimensional vertical velocity profile in an open channel with submerged flexible vegetation. A modified form of the two-dimensional shallow water ...
