Hydrological Processes in the Subsurface Investigated by Water Isotopes and Silica
rainfall to runoff response isotopes
2015/3/1
The hillslope rainfall-outflow interactions, groundwater fluxes, and hydrological balance were examined in the small mountainous headwater catchment Uhlířská, the jizera Mountains, the Czech Repu...
Response of Soil Moisture Change to Hydrological Processes in a Continuous Permafrost Environment
Soil Moisture Change Hydrological Processes Continuous Permafrost Environment
2009/10/26
The moisture content of the active layer at three sites in a continuous permafrost
area was measured using a twin-probe gamma density meter. The moisture
storage status at these sites were related t...
Mathematical Model of Hydrological Processes METQ98 and its Applications
Mathematical Model Hydrological Processes METQ98 Applications
2009/10/23
The mathematical model METQ98 for runoff simulation is described. The
METQ98 is developed from the model METUL (Krams and Ziverts 1993). Input
data for the model are daily mean values of air tempera...
Hydrological processes and water resources management in a dryland environment IV：Long-term groundwater level fluctuations due to variation in rainfall
Long-term groundwater level fluctuations rainfall dryland environment
2009/5/26
To evaluate the effects of variations in rainfall on groundwater, long-term rainfall records were used to simulate groundwater levels over the period 1953-96 at an experimental catchment in south-east...
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...
Hydrological processes and water resources management in a dryland environment I：An introduction to the Romwe Catchment Study in Southern Zimbabwe
Hydrological processes water resources management Southern Zimbabwe
2009/5/26
In Zimbabwe during the 1980s and early 1990s, a sequence of severe droughts caused widespread food shortages and great hardship to rural communities. The droughts exacerbated the problems of environme...
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...
Investigation of dominant hydrological processes in a tropical catchment in a monsoonal climate via the downward approach

2009/5/15
This study explores the dominant processes that may be responsible for the observed streamflow response in Seventeen Mile Creek, a tropical catchment located in a monsoonal climate in Northern Territo...
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...
