Available in PDF, EPUB and Kindle. Book excerpt: The vulnerability of water resources due to climate change and human activities is globally increasing. The phenomenon of hydrological change is complicated because of the combinations and interactions between natural climate fluctuation, global warming and human activities including changes in land utilization. The impact areas of hydrological changes are also not only within the basin, but reach to the ocean through coastal water exchanges. This book presents contributions focused on integrated water management from headwater to the ocean in a time of climate change and increasing population.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater inflows are a crucial component for maintaining estuarine health, function and productivity. Streamflows, the primary source of freshwater inflows, have been modified and altered from their natural flow by population growth and anthropogenic impacts on the contributing watersheds. The Guadalupe Estuary is a primary habitat for many endangered species. The Guadalupe River Watershed, which supplies 70% of freshwater inflows, experiences rapid urbanization and agricultural development. This study proposed to characterize the impact of land use/cover change in the Guadalupe River Watershed on freshwater inflows to the Guadalupe Estuary. Pre-whitening, Mann-Kendall and bootstrap techniques were used to test for significant trends on streamflow and precipitation. Analyses suggested more trends in annual and seasonal minimum and mean streamflow than would be expected to occur by chance in the periods of 1930-2005 and 1950-2005. No significant trends were found in the period of 1970-2005. Significant trends were more prominent in the upper watershed and decreased as analysis moved downstream in the period of 1950-2005. Trend tests on precipitation data in the period of 1950-2005 revealed more significant trends than would be expected by chance in mean annual and winter precipitation. Analyses of Landsat images of the watershed using an unsupervised classification method showed an increase in forest, urban and irrigated land by 13, 42 and 7%, respectively, from 1987 to 2002. Urbanized areas were mostly found in the middle part of watershed surrounding the I-35 corridor. More than 80% of irrigated lands are distributed over the San Marcos and Middle Guadalupe River Watersheds. Soil and Water Assessment Tool (SWAT) model was applied for the Guadalupe River Watershed. Calibration and validation using data recorded at USGS 08176500 indicated the model performed well to simulate streamflow. The coefficient of Nash- Sutcliffe, determination and percent bias were 0.83, 0.96 and 3.81, respectively, for calibration and 0.68, 0.75 and 29.38 for validation period. SWAT predicted a 2% decrease in annual freshwater inflow rates from the effect of land use/cover change from 1987 to 2002. Reservoirs increased freshwater inflows during low flow months and decreased the inflows during high flow months. Precipitation variability changed characteristics of monthly freshwater inflows.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding how species communities respond to land use and environmental change over space and time is necessary given the rapidly changing environment that threaten species persistence. In intrinsically dynamic environments such as estuaries, the spatial and temporal environmental variability at the interface of freshwater and marine ecosystems result in species that persist with morphological or physiological adaptations to these changing environmental conditions. Yet, estuarine fish communities are facing further change as a result of the loss of functional connectivity through stream fragmentation due to culverts that impede fish passage upstream, and land use change as well as climate change among estuaries that reduce habitat quality. It is unknown how the extent of environmental change due to land use and climate change in estuaries and their associated watersheds affect estuarine fish communities in addition to natural variability. In this thesis, I determine how fish communities in estuaries respond to land use impact and environmental variability at the stream and watershed levels. The functional connectivity of species is impacted by stream fragmentation due to culverts upstream of New Brunswick estuaries and their watersheds. I show that the potential functional connectivity of species varies according to migratory traits and the ontogeny of species. In the Miramichi watershed, I assess how forest harvesting and weather fluctuations affect the density of juvenile Atlantic salmon (Salmo salar) at the watershed level. I demonstrate that accounting for the upstream forest harvesting have cumulative impacts on juvenile Atlantic salmon through each catchment downstream and over time. Within and among the estuaries, I find evidence that fish communities shift according to environmental change. My findings relating to the effects of land use and environmental variability from streams to the watersheds would result in a better predictive capacity of how estuarine fish communities will potentially change or persist.

This book was released on 2016 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this study was to determine the relative contributions of increased flood frequency and continued land development on geomorphic change and damage to infrastructure throughout the Yellow Creek, OH watershed. Comprised of five sub-watersheds, the Yellow Creek watershed is located in Northeast Ohio and is a tributary of the Cuyahoga River. In Northeast Ohio, a statistically significant change point in both heavy precipitation and stream flow occurred in July 2003. On the USGS Cuyahoga River Old Portage stream gage record, there were only 18 days of mean daily discharge above the top 1% flood category (76 m3s−1) during the 13 years prior to July 2003 compared to 79 days in the 13 years after July 2003. Land cover data reveals that impervious cover in the watershed has increased by 0.80% from 1985-1996, 0.32% from 1996-2001, 0.67% from 2001-2006, and 0.38% from 2006-2010. The five sub-watersheds have contrasting development histories and vary from 4.5% to 23.5% imperviousness. Water level loggers were installed to measure hydrograph variability between the five sub-watersheds. Water samples were also taken on 11/10/15, 2/3/16, and 2/24/16 in the five sub-watershed streams to find the effect development has on road salt concentration in the stream. Aerial photos for nine years between 1994 and 2015 were used to assess changes in stream geomorphology through time. Results show that geomorphic change has been greater after July 2003 compared to before July 2003. These post-2003 geomorphic changes include an increase in unvegetated mid-channel bars and point bars as well as amplified channel migration. Elsewhere, Yellow Creek shows straightening and widening in response to increased flooding events. The 2000 to 2005 and 2012 to 2015 photo intervals showed the largest geomorphic change throughout the Yellow Creek watershed, especially in areas with steep topography and stream slope. Although urbanization in the watershed results in increased runoff, since 2003 increased flood frequency has a larger effect on geomorphology change than increases in development. Upon analyzing data from water level loggers, results show that land cover, vegetative cover, soils, slope, precipitation intensity, and flood storage capacity all play an important role on hydrograph shape and time of peak discharge between the five sub-watershed streams. Sourek Run is the sub-watershed with the largest amount of impervious cover (23.5% as of 2010) and is the flashiest sub-watershed of the five and sensitive to small-scale precipitation events. The headwater, Upper Yellow Creek with less impervious cover (8.93% as of 2010) shows a generally round hydrograph and arrives later in time relative to other sub-watersheds likely due to its low slope, increased soil storage capacity and infiltration. Winter time snow melt and high magnitude summer time rainfall events created synchronous or near synchronous peak discharge time between the five sites. It also was found that road salt contamination was present in the Yellow Creek watershed during winter months, and the amount of development in the small sub-watershed areas (
