The paper studies the accuracy of modeling moisture transport under conditions sprinkler irrigation using evapotranspiration assessment methods that take into account soil conditions. Appropriate modifications Penman-Monteith and Priestley-Taylor models are considered. Moisture is performed Richards equation in its integer- fractional-order forms. Parameters identification by particle swarm opt...

the assumptions considered in developing the saint-venant equations limit their application in many practical situations. the modified boussinesq equation was presented to overcome the limitation imposed by saint-venant equation due to the presence of non-hydrostatic pressure distribution and steep slope. in this paper a computational model was developed for solving the modified and the traditi...

Daily evapotranspiration (ET) is modeled globally for the period 2000–2013 based on the Penman–Monteith equation with radiation and vapor pressures derived using remotely sensed Land Surface Temperature (LST) from the MODerate resolution Imaging Spectroradiometer (MODIS) on the Aqua and Terra satellites. The ET for a given land area is based on four surface conditions: wet/dry and vegetated/non...

A climate model must include an accurate surface physics scheme in order to examine the interactions between the land and atmosphere. Given an increase in the surface radiative forcing, the sensitivity of latent heat flux to available energy plays an important role in determining the energy budget and has a significant impact on the response of surface temperature. The Penman–Monteith equation ...

r a 200 .008 ress: Sch unl.edu Summary A novel approach has been found to estimate the equilibrium surface temperature (Te) of wet environment evaporation (Ew) on a daily basis. Employing this temperature in the Priestley–Taylor equation as well as in the calculation of the slope of the saturation vapor pressure curve with pan measurements improved the accuracy of longterm mean evaporation (E) ...

L9-: Did not you compare the model results with field measurements at OG? L19: What are “changes in climatic parameters”? Each paragraph in this paper tends to be too long. Please reconsider the structure of the text throughout the paper. P6298L1-: Please show important equations in the model and schematic representation of the model structure. P6299, equation (2) is wrong. This should be chang...

It is well known that lesions affecting the trigeminal nerve may lead to the development ofneurotrophic keratitis (Magendie, I 824), but the incidence and the extent of the keratitis seen by biomicroscopic examination of the cornea, and in particular its effect upon visual acuity, are not well documented. The present study was undertaken to investigate these aspects of keratitis, in corneae ren...

We consider the behavior of particles at ultra relativistic energies, for both the Klein-Gordon and Dirac equations. We observe that the usual description is valid for energies such that we are outside the particle’s Compton wavelength. For higher energies however, both the Klein-Gordon and Dirac equations get modified and this leads to some new effects for the particles, including the appearan...
