Nations, particularly those with well-established infrastructure, have started to look for new, innovative solutions to address the expected, inevitable high demand for primary resources. The WEF (water-energy-food) Nexus approach, which holistically considers the dynamic interlinkages between water, energy, and food resources, has come to the forefront within scientific and practice communities. Supporters assert that sustainable solutions can be revealed through the use of this approach, rather than conventional approaches that often overlook the interlinkages. The authors developed a holistic framework to provide sustainable scenarios that include feasible infrastructure interventions. The framework focuses on water and associated links with other resources, includes a unique analytic tool for quantifying scenarios, and ultimately produces a sustainability analysis of each scenario. Optimal scenarios are offered that consider site-specific dynamic resource interlinkages. The platform was applied to the case study of Matagorda County, Texas, identified as one of the most water-stressed regions in the state of Texas by the Texas Water Development Board, the state’s executive agency for water resources management. High demands from energy and agriculture sectors in the county and sharp population increase in the upper basins, which include the city of Austin, have put great pressures on the water resources of Matagorda County. Farmers have been forced to change their crops from high to lower water-demand crops, in spite of apparent and relatively abundant local water resources. The findings of the case study present a most sustainable scenario, including infrastructure interventions that will increase the annual income of agriculture sector from $188 million to $239 million. The approach also helps preserve resources while reducing annual water and energy demand by 22 million m3 and 21 million kWh, respectively, and does not sacrifice on-going municipal and industrial water use or energy production in Matagorda, Texas

Multi-Project Multi-Resource Leveling Using Mixed Integer Programming
Altun, Murat; Sönmez, Rifat; Akçamete Güngör, Aslı (2018-11-16)
In construction projects, resource leveling aims to provide efficient resource planning during project implementation by reducing possible fluctuations in resource usage. Decision makers mostly focus on the single project to optimize its resource usage by applying various objective functions of resource leveling problem. However, in real life, multiple projects may be performed in the same time period. Hence, leveling the resources of each project separately generates sub-optimal solutions since interaction...
Engineering Properties of Basalt Fiber-Reinforced Bottom Ash Cement Paste Composites
Hanafi, Mohamad; Aydin, Ertug; Ekinci, Abdullah (MDPI AG, 2020-4-21)
<jats:p>Extinction of natural resources builds up pressure on governments to invest in research to find more sustainable resources within the construction sector. Earlier studies on mortar and concrete show that bottom ash and basalt fiber are independently alternative binders in the concrete sector. This study aims to use bottom ash and basalt fiber blends as alternative novel-based composites in pure cement paste. The strength and durability properties of two different percentages of bottom ash (40% and 5...
Development of a GIS-based estimator for streamflow at ungaged catchments
Öcal, Duygu; Kentel Erdoğan, Elçin; Department of Geodetic and Geographical Information Technologies (2017)
Water resources management has been a critical component of sustainable resources planning. One of the most commonly used data in water resources management is streamflow measurements. Daily streamflow time series collected at a streamgage provide information on the temporal variation in water quantity at the gage location. However, streamflow information is often needed at ungaged catchments. One conventional approach to estimate streamflow at an ungaged catchment is to transfer streamflow measurements from the...
