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. ...
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 ...
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 ...
Spatial and Temporal Errors in Estimating Regional Evapotranspiration
Publisher: American Society of Civil Engineers
Abstract: Current methods of computing regional crop evapotranspiration (ET), the prime variable in estimating irrigation demand, largely ignore the spatial and temporal variability of ET parameters, thus introducing errors. In this ...
Irrigation-Drainage Design and Management Model: Validation and Application
Publisher: American Society of Civil Engineers
Abstract: The Colorado State University Irrigation and Drainage (CSUID) model is a simulation model, which can be used in the design and management of conjunctive irrigation and drainage systems. It is based on the numerical ...
Comparison of Ordinary Kriging, Regression Kriging, and Cokriging Techniques to Estimate Soil Salinity Using LANDSAT Images
Publisher: American Society of Civil Engineers
Abstract: The objectives of this study are: (1) to evaluate the LANDSAT best band combinations to estimate soil salinity with different crop types; (2) to compare ordinary kriging, regression kriging, and cokriging techniques to ...
Using Indicator Kriging Technique for Soil Salinity and Yield Management
Publisher: American Society of Civil Engineers
Abstract: This paper presents a practical method to manage soil salinity and yield in order to obtain maximum economic benefits. The method was applied to a study area located in the southeastern part of the Arkansas River Basin in ...
Using Disjunctive Kriging as a Quantitative Approach to Manage Soil Salinity and Crop Yield
Publisher: American Society of Civil Engineers
Abstract: Disjunctive kriging (DK) is a nonlinear geostatistical model that provides unbiased estimates of the conditional probability (CP) that the true value of the property of interest does not exceed a defined threshold. It has ...
