Soil water storage and groundwater behaviour in a catenary sequence beneath forest in central Amazonia：II. Floodplain water table behaviour and implications for streamflow generation
Soil water storage groundwater central Amazonia streamflow generation
2009/6/8
Valley floor groundwater level data collected during the ABRACOS project (Gash et al. 1996), and published streamflow data from small forested catchments in geomorphologically similar areas nearby hav...
Soil water storage and groundwater behaviour in a catenary sequence beneath forest in central Amazonia：I. Comparisons between plateau, slope and valley floor
Soil water storage groundwater central Amazonia plateau valley floor
2009/6/8
Soil water storage was monitored in three landscape elements in the forest (plateau, slope and valley floor) over a 3 year period to identify differences in sub-surface hydrological response. Under th...
The accuracy of simple soil water models in climate forecasting
soil water models climate forecasting
2009/6/8
Several simple soil water models with four layers or less, typical of those used in GCMS, are compared to a complex multilayered model. They are tested by applying a repeating wetting/drying cycle at ...
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...
An Assessment of the Capabilities of the ERS Satellites' Active Microwave Instruments for Monitoring Soil Moisture Change
European Remote sensing Monitoring Soil Moisture Change active microwave instrument
2009/6/8
The launch of the European Remote sensing Satellite (ERS-1) in July 1991 represented an important turning point in the development of Earth observation as it was the first of a series of satellites wh...
A comparison of methods for estimating soil characteristics in regional acidification models; an application of the MAGIC model to Scotland
Acid Neutralising Capacity soil depth soil physico-chemical
2009/6/5
The results from an application of MAGIC (Model of Acidification of Groundwater In Catchments) to 733 Scottish catchments are presented. The availability of representative, good quality soil data is f...
Modelling the response of soil and runoff chemistry to forest harvesting in a low deposition area (Kangasvaara, eastern Finland)
soil runoff chemistry low deposition area maximum feasible reduction
2009/6/5
A simple dynamic soil model developed to analyse the effects of atmospheric deposition and nutrient cycling on terrestrial ecosystems, SMART 2, was applied to the Kangasvaara catchment in eastern Finl...
Comparison of simulated forest soil response to acid deposition reduction with two models of differing complexity
forest soil \acid deposition reduction
2009/6/5
Great effort has been dedicated to developing soil acidification models for use on different scales. This paper focuses on the changes in model performance of a site scale soil acidification model (NU...
Modelling the response of soil and soil solution chemistry upon roofing a forest in an area with high nitrogen deposition
nitrate (NO3) sulphate (SO4) soil solution chemistry
2009/6/5
In the Speuld forest, the Netherlands, the dynamic soil acidification model NuCSAM has been applied to a manipulation experiment in which part of the forest was roofed to control nitrogen (N) and sulp...
Assessing soil calcium depletion following growth and harvesting of Sitka spruce plantation forestry in the acid sensitive Welsh uplands
soil calcium depletion Welsh uplands plantation forestry
2009/6/5
A simple mass balance has been used to estimate soil calcium depletion during the growth of a 50 year old Sitka spruce crop on acid, base-poor peaty podzol soils in upland Wales. Growth of the crop wi...
An analytical solution for the estimation of the critical available soil water fraction for a single layer water balance model under growing crops
soil water single layer water balance model growing crops
2009/6/5
In the framework of simplified water balance models devoted to irrigation scheduling or crop modelling, the relative transpiration rate (the ratio of actual to maximal transpiration) is assumed to dec...
The application of an instrument for non-destructive measurements of soil temperature and resistance profiles at a high Arctic field site

2009/5/27
An easily constructed and installed instrument for measuring colocated soil temperature and resistance profiles is described. Minimum disturbance to the soil structure is achieved. The system indicat...
The dielectric calibration of capacitance probes for soil hydrology using an oscillation frequency response model
soil hydrology oscillation frequency response model
2009/5/27
Capacitance probes are a fast, safe and relatively inexpensive means of measuring the relative permittivity of soils, which can then be used to estimate soil water content. Initial experiments with ca...
