16. Impacts of climate change on surface hydrology in the source region of the Yellow River
Sammanfattning : The source region of the Yellow River contributes about 35% of the total water yield in the Yellow River basin playing an important role for meeting the downstream water resources requirements. The declining water availability caused by climate change in the source region of the Yellow River is expected to have severe repercussions for the 110 million basin inhabitants in terms of water resources affecting agricultural productivity, municipal, and industrial water supply.

17. Water quality modeling based on landscape analysis: importance of riparian hydrology
Sammanfattning : Several studies in high-latitude catchments have demonstrated the importance of near-stream riparian zones as hydrogeochemical hotspots with a substantial influence on stream chemistry. An adequate representation of the spatial variability of riparian-zone processes and characteristics is the key for modeling spatio-temporal variations of stream-water quality. LÄS MER
18. Hydrology and water chemistry in a heterogeneous landscape : process-based modelling of coupled surface water and groundwater flow across contrasting boreal catchments
Sammanfattning : Surface water and groundwater are connected, and the exchange between them is a vital part of a catchment’s hydrology. Along the flow paths through the catchment, biogeochemical processes can change the water’s chemical composition. LÄS MER
19. Hydraulic- hydromorphologic analysis as an aid for improving peak flow predictions
Sammanfattning : Conventional hydrological compartmental models have been shown to exhibit a high degree of uncertainty for predictions of peak flows, such as the design floods for design of hydropower infrastructure. One reason for these uncertainties is that conventional models are parameterised using statistical methods based on how catchments have responded in the past. LÄS MER
20. Intensifying Agricultural Water Management in the Tropics : A cause of water shortage or a source of resilience?
Sammanfattning : Frequent climatic shocks have presented challenges for rainfed agriculture in sub-Saharan Africa. Appropriate water management practices are among the solutions to the challenges. The role of water harvesting in achieving sustainable agricultural intensification and specified resilience was explored. LÄS MER
