Title of Thesis: MAPPING SNOW COVER IN SIBERIA USING GIS AND REMOTE SENSING Aditya Saini, Master of Science, 2003 Thesis directed by: Associate Professor Kaye L. Brubaker Department of Civil and Environmental Engineering The seasonal snowpack dynamics of the Siberian mountains and plains play a critical role in the freshwater fluxes of northern rivers into the Arctic Ocean. This study is part o...

--A historic look at the Colorado River will illustrate the dras­ tic effects of human activity on most Western rivers. Engineering features for the management of water and electric power have resulted in increased evapora­ tion, associated salinity, and other physicochemical changes; drastic reduction in many native plant and animal populations; increasing populations of intro­ duced species; ...

Previous studies have established that under natural conditions, alluvial river confluence zones experience channel scour followed by mid-channel bar development. Less attention is given to bed evolution downstream of large confluences engineered such as discharge regulation and levee confinement. Here we present four decades morphologic changes along the 69-km uppermost Atchafalaya River, a di...

riparian vegetation is a component of river system that performs certain basic functions including primary vegetative production, protecting stream banks from erosion, trapping sediments, promoting water quality, wildlife habitat and fisheris, forage for livestock, etc. in this research, spatio-temporal change of vegetation riparian area of aghbolagh-river as an upstream of karoon-river for 65-...

The 2003 flood of the Muda River reached 1,340 m3 /s at Ladang Victoria and adversely impacted 45,000 people in Malaysia. A flood control remediation plan proposed a levee height based on a 50-year discharge of 1 ,815 m3 /s obtained from hydrologic models. This design discharge falls outside the 95% confidence intervals of the flood frequency analysis based on field measurements. Instream sand ...

The Doctoral Programme in Water Engineering is coordinated by the Department of Hydraulic, Environmental, Infrastructures, and Surveying Engineering (DIIAR). It offers technical/scientific curricula geared to the design, planning and management of sustainable development strategies related to the interactions between human life and environment in all aspect involving water. The programme is foc...

Modelling and simulation of the oxygen-sag model are used to demonstrate the potential benefits of the application of user friendly numerical software packages in environmental engineering education and practice. The simulation is used to obtain the profiles of oxygen concentration, oxygen deficit, as well as de-oxygenation and re-oxygenation rates as function of distance for a steady river vel...
