RISDiscussion of “Unit Curve for Design of Highway Transition” by S. K. Rao
Publisher: American Society of Civil Engineers
Granular-Fluid Chute Flow: Experimental and Numerical Observations
Publisher: American Society of Civil Engineers
Abstract: Equations of motion and boundary conditions for a flowing granular-fluid mixture, both based in the kinetic theory for granular flow, are here extended to allow for drag forces resulting from the interstitial fluid that ...
Parameter Estimation in Groundwater Hydrology Using Artificial Neural Networks
Publisher: American Society of Civil Engineers
Abstract: The capability of artificial neural networks to act as universal function approximators has been traditionally used to model problems in which the relation between dependent and independent variables is poorly understood. ...
Dynamic Modeling of Systems With Translating Components
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper summarizes a method for modeling the vibration response of mechanical systems whose configuration may vary during operation. A model of adjacent elements which experience relative ...
ReSET-Raster: Surface Energy Balance Model for Calculating Evapotranspiration Using a Raster Approach
Publisher: American Society of Civil Engineers
Abstract: Surface energy balance models developed for mapping evapotranspiration at high resolution use weather station data. Previous models such as SEBAL or METRIC use wind and reference evapotranspiration from a single weather ...
Surface Energy Balance-Based Model for Estimating Evapotranspiration Taking into Account Spatial Variability in Weather
Publisher: American Society of Civil Engineers
Abstract: Reliable estimates of evapotranspiration (ET) from vegetation are needed for many types of water-resource investigations. How well models can estimate ET from vegetation varies, depending on the capabilities of the model ...
Using a Surface Energy Balance Model (ReSET-Raster) to Estimate Seasonal Crop Water Use for Large Agricultural Areas: Case Study of the Palo Verde Irrigation District
Publisher: American Society of Civil Engineers
Abstract: Water accounting for agricultural areas is crucial for irrigation water management. Actual crop evapotranspiration (ET) is needed as an important input for agricultural water accounting, yet obtaining accurate measurements ...
Assessing the Impact of Irrigation Return Flow on River Salinity for Colorado’s Arkansas River Valley
Publisher: American Society of Civil Engineers
Abstract: A river salinity model has been developed on the 21 major canal areas in the lower Arkansas River Basin in Colorado to address the impact of irrigation return flow on the river. The quantity of the return flow is predicted ...
Using Cluster Analysis of Hydraulic Conductivity Realizations to Reduce Computational Time for Monte Carlo Simulations
Publisher: American Society of Civil Engineers
Abstract: Despite the conceptual simplicity of Monte Carlo-simulation methods in assessing uncertainty in hydrogeological systems, their use is limited by expensive computational requirements in terms of the large number of realizations ...
Using Neural Networks to Model the Impacts of Climate Change on Water Supplies
Publisher: American Society of Civil Engineers
Abstract: An artificial neural network methodology is developed to investigate the possible effects on monthly and seasonal surface water supplies in Colorado’s Arkansas River Basin under two transient climate change scenarios, the ...
