This paper gives a short overview about the hydrological conditions of Hungary with special attention to waterbudget and water quality problems. It begins with an overview to what extent Hungary is dependent on water, then the waterbudget
of the country is described with special reference to the interests of agriculture and reservoir capacities in the various regions. The second half of the paper focuses on the contamination problems of surface and ground water bodies. - (JS)
In a previous paper (Mills, 2000) the A. described a simple waterbudget model that was applied to Ireland for the period 1961-90, but no model validation was attempted. In this paper the A. examines the relationship between the estimated surplus
water calculated for the catchment of the Shannon River with the measured discharge for that river. The close correspondence between these values suggests that the model is capable of estimating waterbudgets components at this scale. A simple climate
change experiment is presented that evaluates the impact of greenhouse warming on the waterbudget of this catchment. Discussion of the results.
A comparison of moisture scalars and waterbudget methods to assess vegetation-site relationships
Beech ; Biogeography ; Digital elevation model ; Habitat ; Index ; Methodology ; Ohio ; Soil moisture ; United States of America ; Vegetation ; Waterbudget
This study compares 3 approaches, a water-budget approach, and field-based and map-based moisture scalars, in their ability to predict the occurrence of a single species, American beech (Fagus grandifolia), observed in 102, 0.04 ha plots in SE Ohio
. It concludes that a water-budget approach is applicable to a wide range of studies exploring vegetation-site linkages, and in terms of global change, this approach offers the additional benefit of being a dynamic model.

Modelling of water and sediment budget : concepts and strategies in Geomorphological models. Theoretical and empirical aspects.
This paper includes the basic ingredients of water and sediment budgets and offers a brief discussion on problems related to the concepts and strategies of flow models, namely, what are the parameters of water and sediment budget models, and what
is the nature of spatial variations of water and sediment flow models in terms of scale and different environmental conditions (geological, vegetational, climatic, anthropogenic).
A note on the waterbudget of Lake Naivasha, Kenya : especially the role of Salvinia molesta Mitch and Cyperus papyrus L.
The introduction of Salvinia in the 1960's has therefore hardly increased the water loss from the lake, whereas the influence of papyrus on the waterbudget of the lake can not be disregarded. Nevertheless, the waterbudget studies and studies

Based on the analyses of water interactions and water balance, this paper discusses the issues on the assessment and regulation of soil water resources, which lays the scientific basis for limited irrigation and water-saving agriculture.
Dissolved load budget of drainage basin systems on silicate rocks and land use in the Northern Eifel/Germany
Eifel ; Germany ; Hydrochemistry ; Land use ; Sediment budget ; Soil erosion ; Solution load ; Water quality ; Watershed
The purpose of this paper is to estimate the influence of the land use and the water balance on the dissolved load budget in drainage basins on silicate rocks. The water balance in the Hohes Venn and the Rureifel areas is mainly influenced
by decreasing rainfall intensity from the Hohes Venn towards NE. Furthermore, different organic and anorganic soil properties influence the water balance in these areas. The investigation of stream load indicates regional differences of water chemistry

This paper attempts to demonstrate the flexibility of a sediment budget methodology and the value of a step by step approach. The steps that are followed are: an explicit recognition of the time scale of integration of the budget; a recognition

The long-term studies of water and chemical budgets in the Hubbard Brook watershed, White Mountains, New Hampshire, have assumed that the underlying bedrock is watertight and that all of the liquid water discharged from the experimental subcatchment
by a consideration of the watertight-bedrock assumption in relation to the larger issue of water and chemical budgets in a forested ecosystem.
The effects of natural and anthropogenic changes on heat and waterbudgets in the Central Caucasus, USSR

The AA. calculate that during the last 100-140 years, the waterbudget at the highest altitudes in the Central Caucasus has changed in accordance with global climatic change, but that at lower altitudes the major impacts are due to anthropogenic

Sand soils are easily permeable to water, but can retain only a small amount in the root zone. Most of the nutrients are leached with precipitation into the groundwater. The waterbudget of soils is influenced by both structure and mechanical
Spatial patterns and frequency distribution of Late Quaternary waterbudget tendencies in Africa
Regional waterbudget tendencies reported by 14C-dated field data are correlated with Late Quaternary cooling and warming phases. There are clear differences in chronological sequences between the subtropics and tropics. The aridification gradient

Account of differences in the Florida peninsula in sunshine, evaporation and waterbudget, temperature, pressure and winds, humidity and clouds, precipitation, thunderstorms. Additional chapters on tropical storms and hurricanes and climate changes
on rill hydraulics and sediment flux patterns. Results indicate the value of detailed sediment budgets in interpreting their water and sediment flux records, and the necessity of linking such measurements for erosion plots and hillslope segments to rill
The primary objectives of this initial study were to prepare sediment budgets for rill networks developed on a natural soil under simulated rainfall in a laboratory flume (University of Toronto, Scarborough), and identify the effect of confluences

Many land-management decisions would be aided by an understanding of the current sediment production and transport regime in a watershed and of the likely effects of planned land use on that regime. Sediment budgeting can provide this information

The AA. use the term impoundments to refer to artificial water bodies regardless of size (reservoirs and ponds). They examine the role of these small impoundments in the sediment budget, at the sub-continental scale. Specifically, they estimate
the total volume of sedimentation occurring in small impoundments and compare that quantity to other components of the fluvial sediment budget for the conterminous U.S. It is clear that most sedimentation is now taking place in subaqueous rather than
