Available in PDF, EPUB and Kindle. Book excerpt: Water is an essential requirement for human existence. However, due to economic and social developments as well as climate change, both water withdrawals and water supplies are changing significantly. Water consumption has an increasing tendency in all the sectors mainly in agricultural use, industrial and power generation use, and domestic use. The total water demand of US is projected to increase by about 12.3 percent between 2000 and 2050. In the meantime, water supplies are being impacted by climate change and anthropogenic impacts. It has, thus, become a necessity to be able to model and predict the water flow based on integration of spatial elements and atmospheric/climatic changes.The purpose of this project is to model the surface run off in the Yuba River Watershed, California, given the geographic and geomorphologic complexities and the presence of dams that regulate the water discharge. The model used, the Watershed Environmental Hydrology Model, WEHY, utilizes upscaled hydrologic conservation equations to describe the evolution of the hydrologic processes and environmental processes within a watershed in time and space. It is capable of accounting for the effect of heterogeneity within natural watersheds. With the development of modern geographic information system (GIS) and remote sensing technologies, increasingly more watershed physical attributes are digitally available, such as topography, geology, soils, land/vegetation cover, and so on. Because the WEHY model parameters are related to the physical properties of the watershed, it is possible to estimate the geomorphologic parameters and the soil hydraulic parameters of the WEHY model by means of existing GIS data sets that describe the geomorphologic features and the soil conditions. So the geographic and geomorphologic complexities are addressed by WEHY and GIS. Presence of big dams makes it necessary to define operation rules taking care of all the constraints including downstream water demand, flood protection, recreation and fishery. The most important dam in Yuba River Watershed, New Bullards Bar dam, extends about 15 miles upstream, has an estimated usable storage capacity of 966,103 ac-ft, a surface area of 4,790 acres, a shoreline of about 71.9 miles, and a drainage area of 488.6 square miles. While calibrating the surface run off, the various operation rules for the working of New Bullards bar dam were realized and made to run along with WEHY model. The operation rules relate to flood protection, power generation and downstream water demand. In this thesis the above aspects were covered to make New Bullards Bar dam operation rules as per reservoir regulation for flood control laid out by Corps of Engineers Sacramento, California.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In California's northern Sierra Nevada mountains, the fire-dependent processes of forest ecosystems have been interrupted and altered by human land use and fire suppression. U.S. Forest Service policy directs land managers to plan for a future that includes multiple use and the restoration of resilient ecosystems. Planning decisions are to be informed by an analysis of the range of variability of ecological processes at multiple scales. Current climate trends in the northern Sierra are of increasing temperatures, increased precipitation, and earlier snowmelt, as well as changes to the frequency and duration of drought. These climate changes have and continue to influence fire frequency, extent, and severity. For this thesis, project partners and I adapted the Rocky Mountain Landscape Simulator (RMLands), a spatially explicit, stochastic, landscape disturbance and succession model, for use in the Sierra Nevada. RMLands was used to simulate wildfires and vegetation dynamics on a portion of the Tahoe National Forest in California, first under historical climate settings and then under alternative climate trajectories based on the Representative Concentration Pathway RCP8.5 projections. I then quantified the historical and the future ranges of variability in the disturbance regime, seral stage distribution, and patch configuration, and compared these to the current landscape. My results suggest more frequent and extensive high severity fire, as well as higher canopy closure, than most other studies of mixed conifer Sierran forests. However, the results typically agree qualitatively with other research, and some differences may be due to differences in study design. Under warmer and drier future climate scenarios, the total area burned, and the proportion burned at high severity, increased. Due to fire's effects on vegetation, the current landscape departs from either historical or future conditions by several statistical measures. Based on these findings, I recommend that managers implement aggressive restoration efforts, utilize mitigation measures where the consequences of changing fire regimes are socially unacceptable, and carefully balance the needs of different ecosystems and of the resident communities. My study can be used to inform goals and specific strategies in restoration planning and help project planners think about impacts at the landscape scale.
