Analytical Solution of the Richards Equation under Gravity-Driven Infiltration and Constant Rainfall Intensity
Publisher: ASCE
Abstract: In the field of soil hydrology, the Richards equation is commonly used to model water flow in unsaturated soils. The high nonlinearity of the Richards equation makes it very challenging to solve analytically for situations ...
Complex Rating Curves for Sharp Crested Orifices and Rectangular or Triangular Weirs under Unsteady Flow Conditions
Publisher: ASCE
Abstract: The importance of discharge measurements is fully acknowledged in many research fields, mostly in hydrology. Numerous measurement devices and various overflow structures have been proposed for discharge measurements; ...
Maximum Lateral Expansion of Wetting Bulbs from Buried and Surface Point Sources: Implications for Drip Irrigation Design
Publisher: American Society of Civil Engineers
Abstract: In surface and subsurface drip irrigation systems, predicting the size expansion of the wetting bulb and the irrigation time is mandatory for water saving, and helps drive their design and scheduling, which cannot ignore ...
Closure to “Simple Relationships for the Optimal Design of Paired Drip Laterals on Uniform Slopes” by Giorgio Baiamonte
Publisher: American Society of Civil Engineers
Simplified Model to Predict Runoff Generation Time for Well-Drained and Vegetated Soils
Publisher: American Society of Civil Engineers
Abstract: The study of generation process of subsurface stormflow, typical of well-drained and high-permeable soils, can be theoretically carried out by applying the continuity and motion equations with the appropriate boundary ...
Simple Relationships for the Optimal Design of Paired Drip Laterals on Uniform Slopes
Publisher: American Society of Civil Engineers
Abstract: Microirrigation plants, if properly designed, allow water use efficiency to be optimized and quite high values of emission uniformity to be obtained in the field. It is known that disposing paired laterals, in which two ...

Linking the Kinetic Energy Fraction and Equivalent Length Method for Trickle Irrigation Design Under Local Losses
Publisher: ASCE
Abstract: New methods using analytical relationships to design drip irrigation laterals and subunits have been introduced in recent years based on the assumption that minor losses can be neglected. This assumption could be relaxed ...
