An efficient water budget is necessary to develop sustainable practices in irrigated lands and determine future trends. Despite a lack of detailed knowledge, climate change is found to profoundly influence groundwater resources through changes in groundwater recharge, groundwater elevation, and groundwater flow processes. Prediction of the groundwater level (GWL) under a changing climate is essential to improve agricultural management.
The goal of this research is to predict the GWL from 2056 to 2060 in the surrounding area of the MSEA. In order to achieve the target, the first research task is to develop a groundwater flow model and then simulate …

The need for improved water filtration technologies continues to grow on a global scale. Membrane filtration devices are increasing in use because they can remove a variety of contaminants efficiently. The major issue with membrane filters is biofouling. Coating membranes with nanoparticles such as graphene oxide (GO) can increase contaminant removal and decrease microbial growth.
This research characterizes the properties of the GO itself, two procedures for producing GO coated membranes, the properties of the created membranes and the contaminant removal and bactericidal efficiencies of the membranes. Pure water flux values for GO coated membranes prepared using a direct deposition …

Turbulent Circular Culvert Flow: Implications To Fish Passage Design, Amin Mohebbi

Culverts are popular conveyance structures in America and Canada to be used as a fish passage or in sewage collection and disposal systems. Fish passage design criteria is based on biological capabilities of fish whereas it should satisfy hydraulic and hydrological constraints as well. Failing to provide enough low velocity regions for aquatic organisms may result in their mass extinctions. Currently, proper road crossing design depends on either model studies or numerical simulations via Computational Fluid Dynamic (CFD) packages, both of which are expensive and time consuming. Further, although the design procedures released by FHWA recently ensures safe fish migration …
