Trip distributionTrip distribution (or destination choice or zonal interchange analysis) is the second component (after trip generation, but before mode choice and route assignment) in the traditional four-step transportation forecasting model. This step matches tripmakers’ origins and destinations to develop a “trip table”, a matrix that displays the number of trips going from each origin to each destination. Historically, this component has been the least developed component of the transportation planning model.
SahysModSahysMod is a computer program for the prediction of the salinity of soil moisture, groundwater and drainage water, the depth of the watertable, and the drain discharge in irrigated agricultural lands, using different hydrogeologic and aquifer conditions, varying water management options, including the use of ground water for irrigation, and several crop rotation schedules, whereby the spatial variations are accounted for through a network of polygons.
Post-conceptual artPost-conceptual, postconceptual, post-conceptualism or postconceptualism is an art theory that builds upon the legacy of conceptual art in contemporary art, where the concept(s) or idea(s) involved in the work takes some precedence over traditional aesthetic and material concerns. The term first came into art school parlance through the influence of John Baldessari at the California Institute of the Arts in the early 1970s.
Climat alpinthumb|Une région de montagne de climat alpin. Le climat alpin est défini comme le climat des régions situées au-dessus de la limite des arbres. Le climat devient plus froid à mesure que l'altitude augmente. Cette caractéristique est décrite par le gradient thermique adiabatique de l'air : l'air a tendance à se refroidir quand il monte, parce qu'il s'étend. Le gradient thermique adiabatique sec est de 10 °C par kilomètre d'altitude.
Lac de ConstanceLe lac de Constance ou Bodan (Bodensee, , ) est un ensemble de plusieurs plans d'eau situés au nord des Alpes, à la frontière entre l'Allemagne, la Suisse et l'Autriche, alimenté principalement par le Rhin. Le lac de Constance se situe dans les contreforts des Alpes, sur le territoire de trois pays : Allemagne, Suisse et Autriche. Les rives des deux lacs qui le composent sont d'une longueur totale de : se situent en Allemagne, en Autriche et en Suisse.
GIS and hydrologyGeographic information systems (GISs) have become a useful and important tool in the field of hydrology to study and manage Earth's water resources. Climate change and greater demands on water resources require a more knowledgeable disposition of arguably one of our most vital resources. Because water in its occurrence varies spatially and temporally throughout the hydrologic cycle, its study using GIS is especially practical.
