Abstract. SWAT (Soil and Water Assessment Tool) is a continuous-time, semi-distributed, river basin model widely used to evaluate the effects of alternative management decisions on water resources. This study examines application for streamflow simulation in an experimental with mixed-land-use characteristics (i.e., urban/peri-urban) using daily hourly rainfall observations. The main objective ...

Abstract. Sorptivity is a parameter of primary importance in the study unsaturated flow soils. This hydraulic required to model water infiltration into vertical soil profiles. can be directly estimated from functions (water retention and conductivity curves), using integral formulation Parlange (1975). However, calculating sorptivity this manner requires prior determination diffusivity its nume...

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...

abstract infiltration is one of the most important phenomena which is affected by the soil physical and hydraulic characteristics. measurement of infiltration needs the high cost and is time consuming, therefore estimation of infiltration is necessary. also, due to variability of soil moisture, it is important to determine the appropriate model for the estimating the infiltration rate. the pres...

The application of the low impact development (LID) in a cold climate such as northeastern China is constrained by two unresolved research questions with regards to its infiltration potential through winter and varied runoff regimes between winters summers. This study picked typical residential district under construction Changchun, China, modeled storm drainage system without LID facilities ba...

Light (anti-)nuclei in relativistic heavy-ion collisions are considered to be formed by the coalescence mechanism of (anti-)nucleons present work. Using a dynamical phase-space model coupled with multi-phase transport (AMPT) model, we explore formation light clusters such as deuteron, triton and their anti-particles different centralities for $$^{197}$$ Au + at $$\sqrt{s_{NN}} = 39$$ GeV. The c...

Abstract The NA61/SHINE experiment at the CERN Super Proton Synchrotron (SPS) studies onset of deconfinement in hadron matter by a scan particle production collisions nuclei with various sizes set energies covering SPS energy range. This paper presents results on inclusive double-differential spectra, transverse momentum and rapidity distributions mean multiplicities $$\pi ^\pm $$ <mml:math xml...

The object of this study is the process impregnation liquid into bulk material, in particular, soil. Determining parameters a relevant task when assessing consequences an emergency spill hazardous liquid. Infiltration soil leads to pollution water resources. However, greatest danger ignition combustible Based on Green-Ampt model, mathematical description material was built. It system two ordina...
