groundwater upland Central Wales Lower Palaeozoic rocks
2009/6/8
A series of boreholes of up to 50 m depth, drilled into Lower Palaeozoic mudstone, shale and greywacke bedrock in the headwater catchment areas of the River Severn at Plynlimon in Central Wales, show...
Solute dispersion along unsteady groundwater flow in a semi-infinite aquifer
Solute dispersion semi-infinite aquifer unsteady groundwater flow
2009/5/27
Analytical and numerical solutions are obtained for dispersion of pollutants along unsteady groundwater flow in a longitudinal direction through semi-infinite aquifers the permeability of which is ei...
Groundwater-surface water interaction and the climatic spatial patterns of hillslope hydrological response
Groundwater-surface water interaction climatic spatial patterns
2009/5/26
A transient, mixed analytical-numerical model of hillslope hydrological behaviour is used to study the patterns of infiltration, evapotranspiration, recharge and lateral flow across hillslopes. Comput...
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...
Multi-objective calibration of a surface water-groundwater flow model in an irrigated agricultural region：Yaqui Valley, Sonora, Mexico
surface water agricultural region groundwater flow
2009/5/18
Multi-objective optimization was used to calibrate a regional surface water-groundwater model of the Yaqui Valley, a 6800 km2 irrigated agricultural region located along the Sea of Cortez in Sonora, ...
Rainfall-runoff modelling in a catchment with a complex groundwater flow system：application of the Representative Elementary Watershed (REW) approach
Representative Elementary Watershed Rainfall-runoff groundwater flow system
2009/5/18
Based on the Representative Elementary Watershed (REW) approach, the modelling tool REWASH (Representative Elementary WAterShed Hydrology) has been developed and applied to the Geer river basin. REWAS...
Measuring methods for groundwater – surface water interactions：a review
groundwater surface water interactions
2009/5/15
Interactions between groundwater and surface water play a fundamental role in the functioning of riparian ecosystems. In the context of sustainable river basin management it is crucial to understand ...
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...
Is the groundwater reservoir linear? Learning from data in hydrological modelling
groundwater reservoir linear hydrological modelling catchment behaviour
2009/5/13
Although catchment behaviour during recession periods is better identifiable than in other periods, the representation of hydrograph recession is often weak in hydrological simulations. Among the vari...
Groundwater compartmentalisation：a water table height and geochemical analysis of the structural controls on the subdivision of a major aquifer, the Sherwood Sandstone, Merseyside, UK
Groundwater compartmentalisation Sherwood Sandstone water table height
2009/5/13
Compartmentalisation, the subdivision of an aquifer into discrete and relatively isolated units, may be of critical importance for the protection of groundwater although it has been largely ignored i...
Tracing and quantifying groundwater inflow into lakes using a simple method for radon-222 analysis
groundwater radon-222 analysis
2009/5/13
Due to its high activities in groundwater, the radionuclide 222Rn is a sensitive natural tracer to detect and quantify groundwater inflow into lakes, provided the comparatively low activities in the l...
In the last decades, the 18O/16O signature of meteoric water became a key tracer intensively used both in hydrology and in paleoclimatology, based primarily on the correlation of the 18O/16O ratio in...
