Implementing small scale processes at the soil-plant interface – the role of root architectures for calculating root water uptake profiles
small scale processes soil-plant interface root architectures root water uptake profiles
2010/3/5
In this paper, we present a stand alone root water uptake model called aRoot, which calculates the sink term for any bulk soil water flow model taking into account water flow within and around a root ...
Use of soil moisture dynamics and patterns at different spatio-temporal scales for the investigation of subsurface flow processes
soil moisture dynamics subsurface flow processes
2009/7/22
Spatial patterns as well as temporal dynamics of soil moisture have a major influence on runoff generation. The investigation of these dynamics and patterns can thus yield valuable information on hydr...
Hydrochemical processes during snowmelt season in a nival mountainous watershed
nival watershed snowmelt runoff hydrochemical processes
2009/7/14
In a snowy watershed, the response of streamwater chemistry to snowmelt depends not only on meltwater chemistry but on the hydrochemical processes of the subsurface water. In this study, the δ18O valu...
Hydrological processes and water resources management in a dryland environment III：Groundwater recharge and recession in a shallow weathered aquifer
Hydrological processes Groundwater recharge shallow weathered aquifer dryland environment
2009/5/26
In crystalline basement regions of Africa, shallow weathered aquifers provide vital water resources for rural communities. To quantify evidence of the behaviour of these shallow aquifers, groundwater...
Hydrological processes and water resources management in a dryland environment II：Surface redistribution of rainfall within fields
Surface redistribution rainfall within fields Soil water movement
2009/5/26
Soil water movement was studied within fields on two different soil types, a red clay soil and a duplex soil of sand over clay, at the Romwe Catchment in southern Zimbabwe. Each study site comprised t...
Distribution of bog and heath in a Newfoundland blanket bog complex：topographic limits on the hydrological processes governing blanket bog development
derived from digital elevation models bog development multinomial logit
2009/5/26
This research quantified the role of topography and hydrological processes within and, hence, the development of, blanket bogs. Topographic characteristics were derived from digital elevation models (...
Physically-based modelling of hydrological processes in a tropical headwater catchment (West Africa) – process representation and multi-criteria validation
soil moisture West Africa tropical headwater catchment
2009/5/15
The aim of the study was to test the applicability of a physically-based model to simulate the hydrological processes in a headwater catchment in Benin. Field investigations in the catchment have sho...
Extension of the Representative Elementary Watershed approach for cold regions via explicit treatment of energy related processes
Representative Elementary Watershed ordinary differential equations
2009/5/15
The paper extends the Representative Elementary Watershed (REW) theory for cold regions through explicit treatment of energy balance equations to include associated processes and process descriptions....
A daily salt balance model for stream salinity generation processes following partial clearing from forest to pasture
daily salt balance pasture water balance
2009/5/13
We developed a coupled salt and water balance model to represent the stream salinity generation process following land use changes. The conceptual model consists of three main components with five sto...
Assessing winter storm flow generation by means of permeability of the lithology and dominating runoff production processes
winter storm flow coefficients permeability of the lithology runoff production processes
2009/5/13
In this study two approaches are used to predict winter storm flow coefficients in meso-scale basins (10 km² to 1000 km²) with a view to regionalization. The winter storm flow coefficient co...
Identifying runoff processes on the plot and catchment scale
runoff processes plot catchment scale
2009/5/7
Rainfall-runoff models that adequately represent the real hydrological processes and that do not have to be calibrated, are needed in hydrology. Such a model would require information about the runoff...
Impacts of ditch cleaning on hydrological processes in a drained peatland forest
hydrological processes drained peatland forest ditch cleaning
2009/5/6
One fourth of the forests in Finland are growing on drained peatlands. Forestry operations such as ditch network maintenance increase the export of suspended solids and nutrients, and deteriorate wate...
