IISG Projects - Water for Our Future

چکیده
For more than 100 years, the wetland sediments at the Indiana Dunes National Lakeshore (IDNL) and adjacent Indiana Dunes State Park have received atmospheric input of trace metals from industrial sources located upwind and to the west. The objective of this study was to document the extent and magnitude of this trace metal pollution both aerially and with depth within the IDNL, and to identify trends in metal distribution and mobility associated with different hydroperiods/degrees of human disturbance. This information is of value in assessing the potential for heavy metal release associated with changes in hydrology, hydrochemistry and sediment chemistry that may occur during and following wetland restoration of the Great Marsh.

Prediction of remission after metabolic surgery using a novel scoring system in type 2 diabetes – a retrospective cohort study
BACKGROUND Remission of diabetes is seen in more than 60% of patients after bariatric surgery. There is extensive variability in the remission rates between different surgical procedures. We analyzed our database and aimed to develop an easy scoring system to predict the probability of diabetes remission after two surgical procedures i.e. Ileal Interposition coupled with Sleeve Gastrectomy (IIS...
متن کاملIntegrated Planning of Water Resources Based on Sustainability Indices, a Case Study: Hamoon- Jazmorian Basin
Nowadays, the water supply and water demand management are the main issues in water resources planning. It is more important in a river basin with a complex system facing with droughts, climate changes, inter-basin water transfer and operational and under study dams. In this paper, for water resources planning in a river basin and reducing the difference between water resources and water demand...

Water resources development options are usually selected on a least-cost basis. While economic considerations are dominant in choosing projects, there are also a mix of other factors including social demands, political expediency, social equity, and environmental considerations that impact final decisions and development of water supply systems. Understanding local priorities in water resource ...
متن کاملWorld Experiences of Inter-basin Water Transfer Projects and the Necessity of Developing Decision Making Criteria in Iran
When categorizing water management alternatives, to meet water needs, water transfer is seen as an option that tends to supply more water. Most developing countries where limited water resources are available with high spatiotemporal dispersion, favor this option. The numbers of such projects that have been proposed, implemented, and operated in recent years evidence the desirability of this al...
متن کاملApplication of Fuzzy Technique for Order-Preference by Similarity to Ideal Solution (FTOPSIS) to Prioritize Water Resource Development Economic Scenarios in Pishin Catchment
Water is a basic demand of sustainable development in most regions of the world. The non-uniform temporal and spatial distribution of water resources will lead to water shortage in arid and semi-arid areas. Pishin catchment is one of the most important catchments in South-East Iran. The basin had been faced with consecutive droughts in recent years. On the other hand, water resources developmen...
