New Drain Spacing Formulas Using the Variational Iteration Method
Irrigation and Drainage, EarlyView.ABSTRACT In this study, the drain spacing is computed using the variational iteration method (VIM) to the linearized Boussinesq equation. By applying at most two iterations of the VIM method under three different initial condition scenarios, three equations for drain spacing calculation were derived. These equations predict values of drain spacing that

Irrigation and Drainage, EarlyView.ABSTRACT Accurate monitoring of crop water use is critical for precision irrigation, yet conventional lysimeter systems remain too costly and complex for widespread adoption. This study presents the development and field validation of a low‐cost, information and communication technology (ICT)‐enabled weighing lysimeter system that integrates load cells,

Preferential Flow Infiltration Model for Wide Grading Soils Subject to Rainfall Infiltration
工程科学与技术, 2017 :Pore diameters of wide grading soil are across several orders of magnitude.A preference flow which is a kind of unbalanced infiltration in space usually appears under rainfall infiltration condition.Based on the fractal structure of pores,quantitative ...

The water balance of two semi-arid shrubs on abandoned land in South-Eastern Spain after cold season rainfall. [PDF]
, 2002 The inland, mountainous marginal areas (land abandoned by farming and colonised by shrubs) of the Iberian Peninsular, Spain, generally receive a higher rainfall than the coastal areas (Lazaro and Rey, 1991) and may store water after cold season (autumn ...
