Integrierte hydrologische Modellierung von Oberflächen- und Grundwasser in dem mesoskaligen Einzugsgebiet des Rautenbach, Nordhessen
(2021-07)
In den vergangenen Jahren kam es in Europa vermehrt zu sommerlichen Dürreperioden mit erheblichen Beeinträchtigungen der Ökosysteme sowie für Land- und Forstwirtschaft. Die dadurch zunehmenden Herausforderungen an das Wasserressourcenmanagement fordern ein erweitertes Systemverständnis, welches durch realitätsnahe hydrologische Modellierung gewonnen werden kann.
Integrierte hydrologische Modelle ermöglichen die räumlich und zeitlich differenzierte Abbildung ober- und unterirdischer Abflüsse und derer Wechselwirkungen. ...

Energy Budget- and Temperature Index- based Calculations of Seasonal Mass Balances and Discharge in the Tropical Glacier Artesonraju and Artesoncocha Basin in the Cordillera Blanca,
Peru
(2020)
The core of the present Doctoral study deals with glacier simulations for calculating mass balance and discharge in the Artesonraju glacier and Artesoncocha basin, in the Cordillera Blanca (CB), Peru. For this purpose, two different models are used. One is an energy-model (EBM) which is physically based and uses energy fluxes measurements on the glaciers, whereas the other one is a temperature index model (TIM) which is empirical and uses mainly temperature and precipitation as its main input data.
An analysis of ...

Modeling analysis of 21st century climate change projections and their impacts on the hydrology of the Karaj-Jajrood basin, Iran
(2023-12)
Two main rivers, Karaj and Jajrood which provide metropolitan Tehrans’ water, flow in Alborz and Tehran province, respectively. In the last decades, the impact of climate change on temperature and precipitation is tangible in these two provinces. For the Karaj-Jajrood basin, during the period 2003-2012, the minimum temperature increased by 1°C, the maximum temperature by 0.6°C and precipitation decreased by -7%, relative to the average of 1972-2012.
To assess climate change impacts in the region, the Statistical ...
