The effects of precipitation and river runoff anomalies in a coupled ice-ocean model of the Arctic
… the effects of anomalies of precipitation and river runoff on sea ice. A dynamic-thermodynamic sea ice model is coupled to an ocean general circulation model which includes a turbulence closure scheme for the treatment of stability-dependent vertical mixing of temperature, salinity, and …

Characterizing and reconstructing 500 years of climate in the Baltic sea Basin
… Baltic Sea Basin and relates ice coverage and river runoff to changes in atmospheric circulation. The regional climate of the Baltic Sea Basin has been analysed using relevant climatic time series for the past 100–500 years. The time series used in the thesis describe parameters such as …

The Carbon Dioxide System in the Baltic Sea Surface Waters
… with the open ocean and a large inflow of river water. The CO2 system, including parameters such as pH and partial pressure of CO2 (pCO2), has large seasonal and inter-annual variability in the Baltic Sea. These parameters are affected by several processes, such as air–sea gas exchange, …

Energy security in Asia - Himalayan hydropower
… hydropower performance are applied throughout. River runoff is reducing in the Himalayas, threatening to decrease the efficiency of hydropower operation. Reduction in water availability exacerbates water security concerns in the Himalayas. Water and energy security issues are also threatened by …

Spring Hollow Reservoir: Application of a two-dimensional water quality model
… consisted of pump discharge from the Roanoke River, runoff, releases at the dam, leakage, and storage. The geometry of the reservoir was represented by four columns and a variable number of five-foot layers. Through a sensitivity analysis, the parameters that influenced temperature and DO the …

Impact assessment of hydroclimatic change on water stress in the Indus Basin
… network of canals, dams, barrages and tubewells. River flows, primarily fed by snow and glacial melt, are highly seasonal and fluctuate between intense floods and droughts. Built storage is relatively small, with withdrawals averaging at 70% of annual availability. Climate change, growth in …

Water resources planning and climate change adaptation strategies of Sardinian basins under water-limited conditions
… in winter precipitation, a halving of annual river runoff, and an increase of approximately 1 °C in mean annual air temperature. To investigate ecosystem responses to contrasting precipitation regimes, two micrometeorological towers were installed: one in Orroli, a site characterized by …

Dinoflagellate cyst record and paleoceanography through the Pliocene–Pleistocene transition at ODP Site 1143, southern South China Sea
… surface-water productivity due to increased river input, 3) increased sediment accumulation rate as a result of increased fluvial erosion inferred to aid the rapid burial and preservation of these heterotrophic taxa, and 4) increased winter monsoon intensity inferred to facilitate the …

Mixing and secondary circulation in Juan de Fuca Strait
Estuaries, the regions where runoff of fresh water, soil, and contaminants first encounter the ocean, are also primary fishing and recreation areas. It is therefore important to understand the dynamics associated with mixing and currents within these bodies of water. Pollutants and fresh water from …

Umweltgeochemische Charakterisierung der niedermolekularen organischen Fracht des Flußsystems Lippe
Rivers are a sensitive and complex ecosystem hosting a diverse spectrum of organisms. Human activities have resulted in increasing river pollution due to input of organic contaminants into the river systems (anthropogenic input). The main emphasis of the present study is a comprehensive examination …

Extreme events in geoarchives
… sediment cores in Mondsee allowed distinguishing river runoff events from local erosion. Moreover, characteristic spatial distribution patterns of detrital flood layers revealed different depositional processes in the two dissimilar lakes, underflows in Lago Maggiore as well as under- and …
