Analysis and Projection of spatio-temporal Drought and Climate Change Impacts on Groundwater Resources and Surface-Groundwater Interactions for three Iranian Case Studies
(2018-08)
Der Klimawandel und deren Variabilität, wie z.B. die Dürre, wirken sich auf die Wasserressourcen und insbesondere auf die wertvolle Grundwasserressource aus, die im Iran mehr als 80% des Wasserbedarfs aller Bereiche (Landwirtschaft, Haushalt und Industrie) ausmacht. Es ist von größter Bedeutung, Anpassungsstrategien zur Bewältigung dieser Probleme zu finden, um ein nachhaltiges Wasserressourcenmanagement sicherzustellen. In dieser Hinsicht sind physikalisch basierte hydrologische Modelle gekoppelt mit Grundwassermodellen ...

Hydro-economic Modeling for Optimization of Sustainable Water Management of a River Basin in the Wake of Climate Change: Case Study of the Zarrine River Basin (ZRB), Iran
(2018-11)
Food and water security will be a great future challenge due to the growth of population and unsustainable water usage. The renewable water resources in the MENA region including Iran, are expected to decline. This situation is exacerbated by the increasing demands and the rising climate variability in the wake of global climate change affecting adversely the available water resources. This thesis research attempts to evaluate the impacts of climate change and water demands on the hydrological and environmental ...

Evaluation of Statistical-Downscaling/Bias-Correction Methods to Predict Hydrologic Responses to Climate Change in the Zarrine River Basin, Iran
(2018-04-20)
Modeling the hydrologic responses to future changes of climate is important for improving adaptive water management. In the present application to the Zarrine River Basin (ZRB), with the major reach being the main inflow source of Lake Urmia (LU), firstly future daily temperatures and precipitation are predicted using two statistical downscaling methods: the classical statistical downscaling model (SDSM), augmented by a trend-preserving bias correction, and a two-step updated quantile mapping (QM) method. The general ...

Estimating the Effects of Climate Change on the Water Resources in the Upper Indus Basin (UIB)
(2018)
Water balance calculations and spatially distributed rainfall-runoff models require high-resolution climatic datasets as the primary input, however, in the Upper Indus basin (UIB), it is rare to find in-situ observational climate data which have spatial, altitudinal and temporal coverage, suitable enough for distributed hydrological investigations and so for the assessment of climate-change’s hydrological impacts. The average precipitation amounts over the UIB are unrealistically low to sustain the observed discharge ...

Rainfall Prediction with AMSR–E Soil Moisture Products Using SM2RAIN and Nonlinear Autoregressive Networks with Exogenous Input (NARX) for Poorly Gauged Basins: Application to the Karkheh River Basin, Iran
(2018-07-23)
Accurate estimates of daily rainfall are essential for understanding and modeling the physical processes involved in the interaction between the land surface and the atmosphere. In this study, daily satellite soil moisture observations from the Advanced Microwave Scanning Radiometer–Earth Observing System (AMSR–E) generated by implementing the standard National Aeronautics and Space Administration (NASA) algorithm are employed for estimating rainfall, firstly, through the use of recently developed approach, SM2RAIN ...
Dissertation
Climate Change Impact Assessment of Basin-scale Water Allocation and Management in the Karkheh River Basin, Iran
(2018-09-21)
Hydrological research is intended to improve our understanding of hydrologic processes, the role of hydrological systems in providing water for ecosystems and society, and of the water cycle in the functioning of the earth system. The proper understanding of the hydrology of arid and semi-arid regions is becoming increasingly important, due to diminishing projections of water resource availability in response to global environmental changes. The main objective of this thesis study is to investigate the development ...
