This paper presents the analysis of pre- and post-dam hydrologic changes from dams that cover the spectrum of hydrologic and climatic regimes across the United States. The overall goals are to document the type, magnitude, and direction
. The results indicate that the major pulse of dam construction during the previous century has modified hydrologicregimes on a nationwide scale, for large and small rivers.
of hydrologic shifts because of impoundment. To assess hydrologic changes associated with dams, the AA. applied a hydrologic model, the Indicators of Hydrologic Alteration (IHA), supplemented with orientation statistics for certain hydrograph parameters

This article seeks to achieve 2 aims : - to classify the hydrologicalregimes of the rivers Rega, Utrata and Soła, representing different climatic and physio-geographical regions of Poland, and - to assess changes in their regimes following
The separation of hydrological periods and description of river regimes by comparison of probability distribution of water stages by pentads

The paper deals with the problem of the investigation on river regime. The river regime is understood as some type and time structure of hydrological phenomena in the annual cycle. It has been accepted that hydrological periods are means
of the river regime investigations as well as the basis for its characteristics. 0n the example of the Prosna river were presented the usefulness of the described theoretical model and the methods for the separation of those periods in order to investigate

This paper, based on a semi-conceptual hydrological model, analyses global warming effects on the Hanjiang River hydrologicalregimes and water resources, including soil moisture, evaporation, runoff and the transferable water quantity from
The effect of the High Aswan Dam on the hydrologicalregime of the river Nile in The influence of Man on the hydrologicalregime with special reference to representative and experimental basins.
Cet article présente les résultats des études théoriques entreprises depuis 1954 pour déterminer les effets de l'implantation du grand barrage d'Assouan sur le régime du Nil, qu'il s'agisse de l'écoulement liquide ou solide. (RF).

in an environment which is highly variable in terms of atmospheric conditions, and where snow and ice melt play an important role in the natural hydrologicalregime.
This paper studies the change of streamflow and the impact of climatic variability conditions on regional hydrological cycle in the headwater of the Tarim River Basin. This study investigates possible causes of observed trends in streamflow

Urbanisation and industrialisation in the Ostrava region brought in the necessity to build waterworks in the catchment area of the Ostravice River. The extend of the hydrologicalregime changes alters the ecological characteristics of the river
Hydrological monograph of Włocławek reservoir contains selected problems of inland waters. There are presented elements of hydrologicalregime which in result of changes in the river flow conditions caused by ponding-render the specific exploitation
Conditions for water circulation in the Eg basin provided the background to a description of that river's long-term variability of outflow and hydrologicalregime. The importance of different sources in the formation of streamflow was also estimated

Dambos are shallow seasonally waterlogged, tropical and subtropical African wetlands. This review paper, focusing on dambo hydrology, hydrogeology and their primary determinants, highlights the key issues of the debate and draws some overriding
The effect of Kainji Dam on the hydrologicalregime, water balance and water quality of the River Niger in The influence of Man on the hydrologicalregime with special reference to representative and experimental basins.
Les AA. présentent les conséquences du barrage Kainji sur le régime et la qualité des eaux du Niger à Jebba. Les débits maximaux du fleuve ont décru de 6000 à 3500m/s, alors que l'écoulement de basses eaux a triplé. Cette régularisation a également

The almost classic investigation of runoff regimes has been intensified in the last few years. It is a very signifiant part of hydrological research. As the example of Kenya and the Swiss Alps show, the runoff regime analysis gives an important
contribution to solving hydrological, geoecological and watereconomical problems.
