1. Field Measurements and Predictions of River Flow, Sediment Transport and Morphological Changes
Sammanfattning : In an alluvial lowland river, sediment is transported in the form of suspended and bed loads. The fluvial process is the macroscopic view and long-term consequence of sediment movement. LÄS MER
2. Arsenic in Alluvial Aquifers in the Meghna Basin, Southeastern Bangladesh : Hydrogeological and Geochemical Characterisation
Sammanfattning : Elevated levels of arsenic (As) in Bangladesh groundwater has emerged as a massive calamity exposing a large population to the risk of As toxicity from drinking water sources and agricultural products. Holocene alluvial aquifers in the delta- and flood-plains of the Ganges-Brahmaputra- Meghna (GBM) river systems are severely affected by high levels of As in groundwater. LÄS MER
3. Geomorphology and environmental dynamics in Save River delta, Mozambique : A cross-timescale perspective
Sammanfattning : Long-term perspectives on the evolution of river deltas have provided useful knowledge capable of responding to pending questions related to the ongoing climate and environmental changes. Increasing utilization pressure on delta environments has necessitated increased attention to protect the socio-economic and ecological values. LÄS MER
4. A multidisciplinary approach: geophysics, hydrochemistry and hydrometeorology for addressing water security in semiarid alluvial fans
Sammanfattning : Water security offers to the local population an adequate quality and quantity of water for health, economy, livelihoods and ecosystems. Hence, achieving basic levels of water security should be a priority in areas where access to fresh water is scarce. LÄS MER
5. The influence of multiscale hyporheic flow on solute transport : Implications for stream restoration enhancing nitrogen removal
Sammanfattning : Stream water that flows into and out of streambeds is called hyporheic exchange flow (HEF).It continuously interacts with groundwater and thereby affect the water quality of local streamreaches as well as downstream recipients by providing an environment where solutes andenergy can be retained and degraded.
