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...

In the hydrological watershed, some natural processes take place in which interaction of water, soil, climate and vegetation favors capture water. The present study aimed to evaluate preliminary information regarding response water balance a small research watershed with tropical forest cover (15°01'44''N 92°13'55''W, 471 m, 2.3 has). Events precipitation, direct runoff, infiltration rate basef...

use of the double ring infiltrometer to measure soil water infiltration in center pivot irrigation systems is not an accurate approach; because the real conditions of infiltration under center pivot sprinklers is different from what happens in the double ring. in this study, the infiltration parameters were determined under real conditions of a center pivot system. for this purpose, a single ri...

annual fires might change many soil physical properties in semi steppe rangeland.the objective of this study was to investigate the impact of fire on soil physical properties and soil water infiltration parameters in semi-steppe rangeland of karsanak region in chaharmahal and bakhtiari province. therefore, several sites were chosen which were affected by fire at three, two and one years prior t...

Improving soil-water relations by amending soil with biochar might play a significant role in increasing water availability for agricultural crops as well decreasing loss through drainage or runoff. While the effects of on hydrological properties coarse-textured soils are generally positive and well-documented literature, studies fine-textured rather scarce even contradictory. Therefore, aim th...

Wildfire can impact soil-hydraulic properties by reducing saturated hydraulic conductivity and sorptivity, making recently burned landscapes prone to debris flows flash floods. The post-fire hazard window range from years decades. In Northern California, where wildfire frequency is steadily increasing, the recovery wildfires unknown. Following October 2017 Nuns Tubbs fires in Bay Area of we est...

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...
