In order to get the law of rainwater infiltration and progressive water damage, slope Tianshang bridge foundation in Yunnan Province China is taken as engineering basis. The site investigation damaged carried out. traditional Green-Ampt model improved by considering ponding effect dynamic flow on surface. Based variation characteristics wetting front obtained model, failure process with continu...

Among the environmental problems that could affect agriculture, one of most critical is ponding. This may be defined as water storage on surface in concavities and depressions due to soil saturation. Stagnant can seriously crops management agricultural landscapes. It mainly caused by prolonged rainfall events, type, or wrong mechanization practices, which cause compaction. To better understand ...

Accurate inversion of soil hydraulic parameters based on the van Genuchten–Mualem model has received much attention in science research. Herein, a hybrid algorithm method using particle swarm optimization and vector-evaluated genetic was used to invert θs, α, n, Ks, with objective functions infiltration rate, cumulative infiltration, water content. Then, numerical experiments were conducted fou...

Introduction: Athabasca Vallis (Fig. 1) is the youngest known outflow channel on Mars, dated by crater counting at 2-8 Ma [1,2]. In-channel geomor-phic features indicative of flooding include streamlined forms, longitudinal lineations, and transverse dunes [1,2]. The streamlined forms have been hypothesized to be primarily depositional, i.e. composed of sediment deposited out of the floodwater ...
