The Effect of Heterogeneity on Large Scale Solute Transport in the Unsaturated Zone
Effect of Heterogeneity Large Scale Solute Transport Unsaturated Zone
2009/10/27
The effect of natural heterogeneity on large scale solute transport in the unsaturated
zone is investigated using stochastic methods. Several of the physical
parameters that control flow and solute ...
A modeling study of heterogeneity and surface water-groundwater interactions in the Thomas Brook catchment, Annapolis Valley (Nova Scotia, Canada)
A modeling study heterogeneity surface water-groundwater interactions
2009/9/11
A modelling study of the impacts of subsurface heterogeneity on the hydrologic response of a small catchment is reported. The study is focused in particular on the hydraulic connection and interactio...
The aggregate description of semi-arid vegetation with precipitation-generated soil moisture heterogeneity
Biosphere-Atmosphere Transfer Scheme semi-arid vegetation soil moisture
2009/6/8
Meteorological measurements in the Walnut Gulch catchment in Arizona were used to synthesize a distributed, hourly-average time series of data across a 26.9 by 12.5 km area with a grid resolution of 4...
Aggregation effects of surface heterogeneity in land surface processes
Aggregation effects surface heterogeneity land surface processes
2009/5/27
In order to investigate the aggregation effects of surface heterogeneity in land surface processes we have adapted a theory of aggregation. Two strategies have been adopted: 1) Aggregation of radiativ...
Hydrochemical heterogeneity in an upland catchment：further characterisation of the spatial, temporal and depth variations in soils, streams and groundwaters of the Plynlimon forested catchment, Wales
upland catchment Hydrochemical heterogeneity Wales
2009/5/18
The heterogeneous nature of upland hard-rock catchments in terms of geology, geomorphology, superficial deposits, soil type and land use gives rise to a range of hydrochemical characteristics in strea...
Characterization of spatial heterogeneity of groundwater-stream water interactions using multiple depth streambed temperature measurements at the reach scale
water fluxes heat conduction-advection streambed temperature
2009/5/15
Streambed temperatures can be easily, accurately and inexpensively measured at many locations. To characterize patterns of groundwater-stream water interaction with a high spatial resolution, we measu...
Influence of aquifer and streambed heterogeneity on the distribution of groundwater discharge
aquifer streambed heterogeneity groundwater discharge
2009/4/27
The spatial distribution of groundwater fluxes through a streambed can be highly variable, most often resulting from a heterogeneous distribution of aquifer and streambed permeabilities along the flow...
Evaluation of regional acid sensitivity predictions using field data: issues of scale and heterogeneity
streams forestry acidification
2009/3/23
An acid waters sensitivity map has been widely used as a background resource for assessing potential impacts of forest management on stream water acidity within Wales. The validity of this approach ha...
Multifractal modelling and simulation of rain fields exhibiting spatial heterogeneity
spatial rainfall downscaling multifractals
2009/3/17
Spatial multifractals are statistically homogeneous random fields. While being useful to model geophysical fields exhibiting a high degree of variability and discontinuity and including rainfall, they...
Heterogeneity in catchment properties: a case study of Grey and Buller catchments, New Zealand
fractal multifractal scaling landscape patchiness
2009/3/17
The scaling behaviour of landscape properties, including both morphological and landscape patchiness, is examined using monofractal and multifractal analysis. The study is confined to two neighbouring...
Heterogeneity of coral skeletons isotopic compositions during the 1998 bleaching event
isotopic compositions isotopic compositions
2014/5/4
The vulnerability of coral reefs to climate change, such as regional warming, became fully evident during the strong 1997-1998 El Nino event. This El Nino episode was associated with elevated sea-surf...
