The developed method is then being applied to study the solute travel times to ditch drains originating from a field being subjected to a uniform (1) recharge and (2) ponding field over the surface of the soil.
An analytical solution is developed for predicting two-dimensional transient seepage into ditch drainage network receiving water from a non-uniform steady ponding field from the surface of the soil under the influence of source/sink in the flow domain.
For a partially penetrating ditch drainage system being subjected to a uniform ponding field, the travel times of particles from the surface of the soil to the drains are found to be influenced by the anisotropy ratio of the soil, width, depth of penetration and water level heights of the drains (Figs. 7, 8) and the depth of the water head provided at the surface of the soil.
This is an ordinary country town, with trees and ponds, fields and horses.
Tempo plots are applied to the archaeological record of Hawai'i to expose rhythms of i) tradition in taro pond-field construction, ii) innovation in temple construction, and iii) fashion in the harvest of branch coral for use as a religious offering.
Intensification of taro (Colocasia esculeta) production from the creation of lowland pond-field systems is associated with the development of stone-work villages and the increasing control and competition for resources.
"We're still in the shaping mode," Mr. Bainton said of the nuptials, with 100 guests, to take place beside a pond in fields of sage and lavender at the height of August tomato season.
Looming near the pond, amid fields rendered desolate by white plastic crop covers, was a disintegrating mountain of "ecoballs" — shrink-wrapped bales of Neapolitan garbage that had been dumped all over the Campanian countryside and become a symbol of Italy's environmental crisis.
