New Methods for Aquifer Parameters from Slug Test Data
(American Society of Civil Engineers, 2007)An objective method and a diagnostic curve method are developed for estimating the aquifer parameters (storage coefficient and transmissivity) from slug test data on a fully penetrating well. In the objective method, ... -
Simple Approximation of Well Function for Constant Drawdown Variable Discharge Artesian Wells
(American Society of Civil Engineers, 2007)A simple approximation of the well function for a constant drawdown is developed. This approximation is used to estimate the storage coefficient and transmissivity of the aquifer from observed unsteady discharge under a ... -

Development of Experimental Test Setup to Evaluate Abrasion Characteristics of Drainage Pipes
(American Society of Civil Engineers, 2007)The longevity of drainage pipes is dependent on the material properties of the pipe, the surrounding load, the abrasive characteristics of the effluent, and the frequency, velocity, and quantity of the effluent that flows ... -
ANSWAPPS: Model for the Analysis of Grass Swale-Perforated Pipe Systems
(American Society of Civil Engineers, 2007)A computer model for the analysis and design of grass swale perforated pipe systems is presented. The model, which was calibrated and validated using experimental as well as field data, performs detailed computations for ... -
Model to Forecast Maximum Flows in On-Demand Irrigation Distribution Networks
(American Society of Civil Engineers, 2007)A model is developed using data from an on-demand pressurized water distribution network located in sector VIII of the Genil-Cabra irrigation district of Santaella, Córdoba (southern Spain), to simulate an irrigation season ... -
Hydrology and Nitrogen Components of a Simple Rye Growth Model
(American Society of Civil Engineers, 2007)Cover cropping practices are being researched to reduce artificial subsurface drainage nitrate-nitrogen (nitrate-N) losses from agricultural lands in the upper Mississippi watershed. A soil-plant-atmosphere simulation ... -
Multislit Weir Characteristics
(American Society of Civil Engineers, 2007)The slit weir has been recently shown to be effective in measuring very small discharge rates. In this study, the slit weir concept is extended to permit one to measure both very low and very high discharge rates accurately. ... -
Estimating Evapotranspiration Using Artificial Neural Network and Minimum Climatological Data
(American Society of Civil Engineers, 2007)The objective of this study was to test an artificial neural network (ANN) for estimating the reference evapotranspiration (ETo) as a function of the maximum and minimum air temperatures in the Campos dos Goytacazes county, ... -
Load Modeling Approach for Evaluating Selenium Stream Standards Compliance
(American Society of Civil Engineers, 2007)Elevated selenium concentrations have been observed in several rivers in the western United States and are a concern for healthy aquatic systems. Water quality modeling is a valuable tool for quantifying the importance of ... -
Minimum Cost Irrigation Network Design Using Interactive Fuzzy Integer Programming
(American Society of Civil Engineers, 2007)Minimum cost irrigation network design has been conventionally based on crisp pressure requirements at the hydrants of the network. In order to incorporate obscure knowledge on these pressure requirements at the design ... -
Analytical Relationships for Designing Multiple Outlets Pipelines
(American Society of Civil Engineers, 2007)In this paper an analytical procedure taking into account the nonuniform outflow profile for hydraulic analysis and design of multiple outlets pipelines, is presented. Energy relations are improved based on the average ... -
Rational Coefficients for Steeply Sloped Watersheds
(American Society of Civil Engineers, 2007)When computing peak discharges for the design of drainage systems using the rational method, it is important to have an accurate value for the rational coefficient -
Optimal Design of Channel Having Horizontal Bottom and Parabolic Sides
(American Society of Civil Engineers, 2007)The cost of open channels can be minimized by using (1) the optimal design concept; (2) a new geometric shape to substitute for the trapezoidal channels, and/or (3) a composite channel. The channels in which the roughness ... -
Simulation of Processes Involved in Soil Salinization to Guide Soil Remediation
(American Society of Civil Engineers, 2007)The man-made development of lands for irrigated agriculture has provided benefits, but in some schemes has resulted in catastrophic problems arising from soil salinization including those in the Aral Sea Basin in central ... -
Deciding Alternative Land Use Options in a Watershed Using GIS
(American Society of Civil Engineers, 2007)The present approach adopted for suggesting alternative sustainable land use comprises taking into consideration present land use/land cover, soils, slope, and geomorphology. However, this paper deals with watershed ...
