Abstract The land load in the Air Dingin Sub-watershed is increasing due to relocation of Padang City administrative center district. Subsequently, this not only reduces catchment area but also increases surface runoff, because open green space, which originally served as a area, has been converted into settlements. A random measurement infiltration rate with double-ring infiltrometer was used ...

Abstract. The saturated hydraulic conductivity (Ksat) is a key soil property governing agricultural production. However, the influence of conversion from conventional tillage (CT) to conservation (CS; including no tillage, NT, and reduced RT) on Ksat soils not well understood still debated. In this study, we applied global meta-analysis method synthesize 227 paired observations for 69 published...

An automated tension infiltrometer including a soil contacting base to which is mounted a porous plate for interfacing the infiltrometer with the soil to be analyzed. A Marriotte column is positioned in the base so that its open bottom end abuts the porous plate. A bubble tower is also positioned in the base and has a bubbling tube operatively connected between its interior and interior of the ...

A key parameter for the design of soil drainage and irrigation facilities modelling surface runoff erosion phenomena in land-formed areas is saturated hydraulic conductivity (Ks). There are many methods determining its value. In situ laboratory measurements commonly regarded as most accurate direct methods; however, they costly time-consuming. Alternatives can be found increasingly popular mode...

Evaluation and modeling of soil water infiltration are essential to all aspects resources management the design hydraulic structures. Nonetheless, research focused on experimental studies rates in arid semi-arid regions under unknown boundary conditions remains minimal. This paper investigates characteristics spatial variability over a rural basin Algeria. The experiments were conducted using p...

Developing correlations between various soil parameters are considered the major challenge to diminish time and cost associated with field measurements. Soil hydraulic and physical properties were extensively characterized using tension disc infiltrometer and soil sampling in a silty clay agricultural field in Kalaat El-Andalous, Tunisia. Tension disc infiltrometer experiments were conducted at...
