  2. 1. Arsenic in Alluvial Aquifers in the Meghna Basin, Southeastern Bangladesh : Hydrogeological and Geochemical Characterisation

    Author : Md. Aziz Hasan; Prosun Bhattacharya; William Burgess; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alluvial aquifer; groundwater; arsenic mobilisation; geology; Meghna basin; Bangladesh; Water engineering; Vattenteknik;

    Abstract :  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. READ MORE

    Abstract : Grassland and farmland degradation is considered as one of the worst environmental and economic threats for China. The degradation process negatively affects food and water security, economy, society and climate changes. READ MORE

  5. 3. Farm-based technologies for management of risks from irrigation with wastewater-polluted sources in Cochabamba, Bolivia

    Author : Luis Fernando Perez Mercado; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Wastewater irrigation is a global practice that allows reusing water and nutrients in agriculture, but also poses risks of introducing pathogens/pollutants into agricultural systems and food. In order to manage these risks, on-farm measures can be implemented as barriers along the pathway that pathogens/pollutants must follow to reach the population/place at risk, in cases where treatment plants are not a viable option.

  6. 4. Sediment Characteristics and Sedimentation Rate Estimation in the Dukan Reservoir

    Author : Rebwar Hassan; Nadhir Al-Ansari; Sven Knutsson; Salahalddin S. Ali; Fadhil Ahmed Ameen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Area-storage-capacity curves; Bathymetric survey; Dukan dam; Land use; Reservoir sedimentation; Sediment trap efficiency; SWAT; Soil Mechanics; Geoteknik;

    Abstract : The Dukan Reservoir has been created from the construction of the Dukan Dam on the Lesser Zab River where it crosses the Khalakan Thrust Sheet (Khalakan Mountains) through a gorge 65 km northwest of Sulaimani and 295 km northeast of Baghdad. The Dukan Dam is a multi-purpose dam which was built from 1954 to 1959 to control the flooding of the Lesser Zab River, and to provide irrigation, hydroelectricity, and water storage. READ MORE
