Past hydrological events related to understanding global change
From its origins as a geological study of flood erosion and sediments the science palaeoflood hydrology matured to become an indispensable means for understanding the hydrology of very large, rare floods. Such floods are increasingly posing risks
to human habitation. More that 3 decades of research in palaeoflood hydrology produced spectacular advances in capabilities for : accurately determining palaeoflood ages; quantifying the magnitudes and dynamics of palaeoflood processes; and incorporating
This paper examines the hydrological connectivity and the storage status of a cluster of tundra ponds in a High Arctic polar oasis, relating seasonal hydrological changes to lateral drainage, pond water balance and active layer thaw conditions.
Hydroclimatic analysis of a carbonate island pond through the development of a hydrologic landscape unit model
Bahamas ; Carbonate rock ; Climate ; Hydrology ; Impact ; Island ; Model ; Pond ; Water resources
The aim of this study is to develop a methodology that allows for an estimate of the hydroclimatic influence on an inland pond system on San Salvador, Bahamas. The methodology utilizes the Hydrologic Landscape Unit (HLU) model, a new conceptual
Deep infiltration through a sandy alluvial fan in semiarid Niger inferred from electrical conductivity survey, vadose zone chemistry and hydrological modelling
Aquifer ; Geophysics ; Groundwater ; Hydrology ; Infiltration ; Model ; Niger ; Runoff ; Semi-arid area
For this study, the water balance of the fan was computed at the rainfall-event scale through the 1992-2002 decade, thus providing consistent values of annual surface water loss by infiltration. From this set of data, a hydrological functioning
Reconstructing extreme flows using an airflow index-based stochastic weather generator and a hydrological simulation model
Past hydrological events related to understanding global change
Climatic data ; Flood ; Hydrology ; Model ; Potential evapotranspiration ; Precipitation ; Simulation ; Stream ; Stream flow ; Twentieth Century ; United Kingdom ; Wales
This paper offers an alternative to the use of geomorphological and sedimentological evidence for the reconstruction of flood and low flow frequencies. It is based on a technique developed to estimate the hydrological impact of future climate change
Evolution of channel morphology and hydrologic response in an urbanizing drainage basin
Baltimore ; Channel geometry ; Flood ; Hurricane ; Hydrological regime ; Hydrology ; Maryland ; Stream ; United States of America ; Urbanization ; Watershed
Here the AA. examine changes in channel morphology and trends in hydrologic response in Dead Run, a stream located in the Baltimore metropolitan area whose catchment experienced substantial land use change associated with urban development
Past hydrological events related to understanding global change : an ICSU research project
Past hydrological events related to understanding global change
Past hydrological events investigated using palaeoenvironmental techniques, over time periods longer than the period of continuous records, are a possible source of information to complement monitored records. Six international research groups have
each contributed results from their specific time and spatial scales in integrated research collaboration. Relevant research conclusions have been combined and a research project undertaken. A provisional protocol for use of past hydrological events
A comparison of SRTM and high-resolution digital elevation models and their use in catchment geomorphology and hydrology : Australian examples

hydrological and geomorphological statistics and descriptors such as the area-slope relationship, cumulative area distribution and hypsometric curve, along with Strahler and networking statistics. Care must be used for quantitative assessment of catchment
hydrology and geomorphology, as in all cases SRTM-derived catchment area is incorrect and smaller digital elevation grid sizes are required for accurate catchment-wide assessment.
In regional scale, to answer a wide range of meteorological and hydrological subjects, University of Tsukuba decided to conduct a researh project entitled Multi Monitoring of Meteorological and Hydrological Elements at Mt Tsukuba and Analyses

Past hydrological events reflected in Holocene history of Polish rivers
Past hydrological events related to understanding global change
A database of 335 radiocarbon dates from Holocene fluvial sediments in Poland has been compiled. All samples were grouped into one of 7 regions characterized by hydrological regime, and one of 8 depositional environments. Statistical analysis
Modelling the potential impacts of groundwater hydrology on long-term drainage basin evolution
Discharge ; Drainage ; Groundwater ; Hydrology ; Numerical model ; Pennsylvania ; Precipitation ; United States of America ; Watershed
The AA. investigate the role that groundwater movement plays in long-term drainage basin evolution by modifying a widely used landscape evolution model to include a more detailed representation of basin hydrology. Groundwater flow is simulated

Hydrology and dynamics of a polythermal (mostly cold) High Arctic glacier
To improve the understanding of the interactions between hydrology and dynamics in mostly cold glaciers (in which water flow is limited by thermal regime), the AA. analyse short-term (every 2 days) variations in glacier flow in the ablation zone
