Including the spatial dimension: using geographical information systems in hydrology
Bibliography ; Geographical information system ; Hydrology ; Model ; Spatial variation
Given the increased use of GIS the aim of this article is to review the current role and limitations of GIS use in hydrology. Initially the various approaches that have been adopted already to capture the spatial characteristics of a hydrological
study area are outlined. This is followed by a synthesis of the current state of GIS and the models used to conceptualize spatial data within such systems. The suitability of such models for application to hydrological research is then emphasized.

Applied hydrology ; Drought ; Hydrology ; Midwest ; Precipitation ; Spatial variation ; Stream flow ; United States of America ; Water resources ; Watershed
This paper examines the hydroclimatic variability among 19 Midwestern basins and examines how the occurrence of hydrologic drought varies among these basins during the 1950-1990 period.

L'A. présente un concept modifié des hydrological response units pour la modélisation régionale des bassins hydrologiques en utilisant le modèle PRMS/MMS. Le concept a été appliqué à un bassin hydrologique d'environ 216 km2, celui de la Bröl, dans
Some geomorphological-hydrological aspects of rock glaciers in the Andes (San Juan, Argentina)
Andes ; Argentina ; Glacier ; Hydrology ; Meltwater ; Mountain ; Periglacial features ; Permafrost ; Rock glacier ; Semi-arid area ; Water resources
In this paper attention is drawn to a relatively unknown aspect of permafrost phenomena: the hydrological characteristics of rock glaciers. Therefore, this paper examines the importance of the water storage of rock glaciers in a semiarid subtropical
This paper provides a review and a synthesis of the work done between 1981 and 1995: detailed studies of surface velocity, glacier hydrology and ice dynamics. Small glaciers, such as Storglaciären, are not as sluggish as may be expected but exhibit
Changes in the hydrology and sediment transport produced by large dams on the lower Ebro river and its estuary
Ebro ; Estuary ; Fluvial hydrology ; Hydraulic works ; Seasonal variation ; Sediment transport ; Spain ; Stream ; Tarragona ; Water use
The aim of this paper is to analyse the changes in the hydrology and sediment transport in the lower Ebro river and its estuary as a consequence of dam construction and increased water uses in the basin. Changes at different time-scales
Hydrologic sensitivity to climate change and some implications for erosion in the Langrivier catchment, Western Cape, South Africa
Aridity ; Cape Province ; Climatic variation ; Climatic warming ; Fire ; Global change ; Hydrology ; Model ; Precipitation ; Sediment budget ; Slope gradient ; Soil erosion ; South Africa ; Watershed
The ACRU hydrologic simulation model was set up for the Langrivier catchment, Western Cape. Hydrologic responses to a range of doubled CO2 global warming climate scenarios were simulated. Thereafter, the hydrologic effects of possible plant
physiological responses to global warming, and hence changes in water-use characteristics, were modelled. Results indicate that hydrologic processes in the study area are most sensitive to variations in precipitation. An altered precipitation regime could affect

Using a combined slope hydrology/stability model to identify suitable conditions for landslide prevention by vegetation in the humid tropics
This paper exammines some of the limitations in current practices, and presents an alternative approach using an adapted version of the distributed slope hydrology and stability model developed by Anderson and Lloyd (1991). The new scheme
incorporates the major mechanical and hydrological effects of vegetation relevant to slope stability in a humid tropical environment. Using this model structure, a series of applications have been carried out to assess the complex stability responses to using
To stop further deterioration of fens and fen meadows and to improve fen conservation it is accepted that there should be a better understanding of the interaction between the hydrological and soil conditions in fens. This Ph.D. thesis focuses

The hydrological conditions of the Hungarian upper (the Hungarian-Slovak border) stretch of the Danube river befor construction of the Bös hydropower plant ant the most important engineering data of the Bös-Nagymaros hydropower scheme
and of the Dunacsúny dam (variant C) are described. The changes in water level discharge, sediment and bed load transport of the Danube river due to the construction of Bös hydropower plant are tackled. The effects of the changes of hydrologic conditions on the natural
