In this analysis, a semi-distributed conceptual runoff model was applied in five basins varying in area between 43 and 195 km, lying in different physiographic regions of Switzerland (lowland, alpine, heavily glaciated high alpine basins) representing various runoff regimes. An objective, labour-intensive optimization procedure was developed and found suitable for deriving optimal parameter val...

The Mesopotamian Plain is part of the Mesopotamia which extends for vast area bigger than plain. plain almost flat and lowland, has clearly defined physiographic boundaries with other surrounding provinces. a huge accumulation geomorphologic unit, where fluvial, lacustrine, Aeolian landforms prevail; fluvial units being abundant among others. However, estuarine marine forms also are developed, ...

to modeling of suitability iranian oak site to establish coppice regenerations, chahartagh forest reserve, ardal region, chaharmehal and bakhtiari province, southern zagros forest, and southwest iranian state was selected. to modeling suitability iranian oak used the physiographic element, soil depth, climatology and distance from village selected. to this study used the raster formats by pixel...

1. Invasive species are present worldwide, yet predicting which invasive species will become problematic in which ecosystems remains an important ecological challenge. Floodplains are at particular risk for invasion, especially when subjected to anthropogenic disturbance. 2. We examined how components of flood regime, habitat quality and habitat configuration influenced the presence and abundan...

A series of models of the lunar interior are derived from topographic, gravitational, librational, and seismic data. The librational parameters and low-degree gravity harmonics result primarily from surface height variations and only secondarily from lateral density variations. The moon departs from isostasy, even-for the low-degree harmonics, with a maximum superisostatic stress of 200 bars un...

From April 1997 through April 1998, 128 raccoons (Procyon lotor (Linnaeus)) collected from 7 sites representing 4 physiographic areas in South Carolina were examined for gastrointestinal helminth parasites. Four species of nematodes (Gnathostoma procyonis (Chandler), Physaloptera rara Hall and Wigdor, Arthrocephahis lotoris (Schwartz), and Molineus barhatus Chandler) and 2 species of acanthocep...
