Legacies of consecutive summer droughts on soil-borne plant parasitic protists (Oomycota: Stramenopila and Phytomyxea: Rhizaria) and protistan consumers (Cercozoa: Rhizaria) along an experimental plant diversity gradient. [PDF]
New PhytolSummary Increasing frequencies of severe summer droughts and plant diversity loss disrupt ecosystem functioning and stability of European grasslands. Understanding how these factors interact with pathogens is crucial. We investigated the effects of plant diversity and repeated summer drought on soil‐borne parasites within a grassland biodiversity ...

Journal of Water and Land Development, 2018 Surface runoff is a major problem in urban catchments; its generation is always related to the amount of effective rainfall dropped over the surface, however in urban catchments the process is considerably altered by the emergence of impervious areas. In

Modification of Green-Ampt model based on the stratification hypothesis
Shui kexue jinzhan, 2012 A modification of Green-Ampt model is proposed based on the stratification hypothesis,which dynamically divided the soil column is into saturated layer,transient layer and dry layer.The model uses the concept of an equivalent hydraulic conductivity in ...

Coupling Green-Ampt and Saint-Venant Equations for Estimating of Transmission Losses during Flood Routing in Rivers [PDF]
علوم و مهندسی آبیاری, 2016 Volume of flooding flow volume in ephemeral streams decreases due to evaporation as well as the channel wall and bed penetration. This process is known as transmission losses.

A Dynamic Multidomain Green‐Ampt Infiltration Model [PDF]
Water Resources Research, 2018 AbstractShrink‐swell soils possess dynamic hydraulic properties, which may limit the applicability of traditional models for simulating infiltration and overland flow. This study incorporates Green‐Ampt infiltration concepts into a multidomain porosity framework to account for variations in pore size distributions and saturated hydraulic conductivities
