A simple model for flow on hillslopes

A Simple Model for Flow on Hillslopes

A simple hillslope hydrological model predicting water movement on sloping shallow soils is developed. Unlike existing hillslope models, the new model can be used to predict flow for long records of climatological data and it can be easily extended to include preferential flow. It compares favorably to other models with more restrictive input requirements. Its application is illustrated for exp...

A New Simple Analytical Model for Flow Analysis Over Slender Delta Wings

A Simple Theoretical Model for Prediction of Phase Inversion

Phase inversion in liquid-liquid dispersions corresponds to the transitional boundary between Oil-in-Aqueous dispersion and Aqueous-in-Oil dispersion. A theoretical model based on simple assumptions was proposed to predict phase inversion point, ambivalence region and the hysteresis effect of inversion. Experimental data from the literature were used to validate the model and results were c...

Conceptualizing lateral preferential flow and flow networks and simulating the effects on gauged and ungauged hillslopes

[1] One of the greatest challenges in the field of hillslope hydrology is conceptualizing and parameterizing the effects of lateral preferential flow. Our current physically based and conceptual models often ignore such behavior. However, for addressing issues of land use change, water quality, and other predictions where flow amount and components of flow are imperative, dominant runoff proces...

A simple Analytical model for solidification cooling rate based on the local heat flux density

A new simple analytical model for prediction of cooling rate in the solidification process based on the local heat flux density extracted during solidification is introduced. In the modeling procedure, a solidifying control volume is considered in the mushy zone in which a heat balance equation is used to derive the present model. As the local heat flux density is a measurable parameter, the pr...
