This book was released on 2011 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study is to investigate variation in water export and instream temperatures throughout the open water season in a beaded Arctic stream, consisting of small pools connected by shallow chutes. The goals are to better understand heat and mass movement through these systems, how this may impact chemical and biological processes, and the resulting shifts with changes in climate. This is accomplished by first examining the extent and variability of water storage and export through qualitative analysis of observational data. Further, heat fate and transport is examined through development of an instream temperature model. The model formulation, a simple approach to model calibration and validation, and information regarding residence and characteristic times of different pool layers are presented. Using temperatures measured at high spatial resolution within the pools and surrounding bed sediments as well as other supporting data (e.g., instream flow, specific conductivity, weather data, and bathymetry), various types of storage within the pools, banks, and marshy areas within iv the riparian zone, including subsurface flow paths that connect the pools, were found. Additionally, data illustrated that some pools will stay stratified during higher flow periods under certain weather conditions. Through modeling efforts, the dominant heat sources were found to vary between stratified layers. It was also found that potential increases in thaw depths surrounding these pools can shift stratification and mixing patterns. These shifts can further influence mass export dynamics and instream water quality. Given the amount and different types of storage within these systems and the influence of stratification patterns on the residence times in the pools, Imnavait Basin and similar beaded Arctic watersheds will likely experience delayed export of nutrients that are limiting in most Arctic systems.

Book Synopsis Temperature Prediction in Stratified Water by : Patrick J. Ryan
Download or read book Temperature Prediction in Stratified Water written by Patrick J. Ryan and published by . This book was released on 1971 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predictions of the complex annual cycle of temperature changes in a lake or reservoir are necessary if proper water quality control is to be achieved. Many lakes and reservoirs exhibit horizontal homogeneity and thus a time-dependent, one-dimensional model describing the temperature variation in the vertical direction is adequate. A discretized mathematical model was developed based on the absorption and transmission of solar radiation, convection due to surface cooling and advection due to inflows and outflows. The model contains provision for simultaneous or intermittent withdrawal from multi-level outlets and time of travel for inflows within the reservoir.

Book excerpt: Water temperature is a critical water quality parameter that affects salmonid survival by influencing its metabolism and growth at all life stages. Stream temperature is an especially important parameter in California rivers where it frequently limits the range of salmonids. Anthropogenic activities have increased stream temperature and degraded spawning, holding, and rearing habitats, and this has contributed to declines in salmonid populations in California. Fisheries managers have a range of analytical and empirical tools available to assess and quantify elevated stream temperature conditions, but many of these tools do not focus on water temperature conditions at the spatial and temporal scales important to salmonids. My research focuses on assessing water temperature at the watershed and upwelling hyporheic scale which are critical to salmonid survival as stream temperature approaches thermal tolerances. I developed a model to calculate water temperature at locations throughout a watershed to provide a method to evaluate the availability and connectivity of suitable thermal habitat throughout a stream network. The model used a linear weighted average of the maximum and minimum air temperatures of the current and 4 prior days. The weighting parameter is dependent upon upstream drainage area enabling the application of the model to both small tributaries and large mainstem streams. I used historical data from the Sonoma Creek, Napa River, and Russian River watersheds to develop, test, calibrate, and partially validate the model. Model results from Sonoma Creek and Napa River indicated it was generally able to estimate daily average water temperature within 1.5 degrees C of the observed water temperature. Data from the Russian River highlighted the model was limited to streams without significant hydrologic modifications or geologic constraints that forced groundwater to the surface. A 1-D advection dispersion heat transport model was developed to quantify the upwelling hyporheic temperature that provides cold water thermal refugia along a streambed for salmonids. I analyzed hyporheic temperature measured at five sites in a previous research program across sixteen kilometers of Deer Creek near Vina, California, to test, calibrate, and partially validate the model. At three sites, I found the 1-D advection and dispersion were the dominant heat transport mechanisms with model root mean square error less than 0.6 degrees C. At two sites, the model was not applicable because modeling results indicated that surface flow rate variations, solar radiation, and multi-day flow paths also influenced the upwelling hyporheic temperature. Modeling was valuable for highlighting the contribution of these additional processes from that of 1-D advection dispersion. The availability of monitoring data over the summer-fall period was essential for modeling upwelling temperature dynamics along a semi-natural channel.
Book Synopsis Development of a Simplified Approach for Assessing the Effects of Water Release Temperatures on Tailwater Habitat Downstream of Fort Peck, Garrison, and Fort Randall Dams by : John M. Nestler

Nestler and published by . This book was released on 1993 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increased water resources demand in the main stem Missouri River regulated by Corps of Engineers dams has intensified the conflict between the economic benefits of stream regulation and the need to protect natural river ecosystems. Credible predictive tools that can be quickly and easily applied are required to explore and screen alternative reservoir operating plans to determine the downstream water temperature effects on tailwaters supporting temperature-sensitive fishes. The screening model was developed in a two-step process. First, a one-dimensional, longitudinal, riverine model, CE-QUAL-RIV1, was used to predict the downstream water temperature in the 52-mile tailwater of Fort Randall Dam, the 70-mile tailwater of Garrison Dam, and the 186-mile tailwater of Fort Peck Dam on the Missouri River. The power of the comprehensive water-quality model was required to predict the complex downstream water temperature patterns resulting from variable year-to-year stratification, complex peaking hydropower release patterns, and variable meteorologic conditions. Downstream water temperatures were simulated for 108 scenarios for each tailwater, covering the expected range of boundary conditions. Second, the output from the 108 scenarios for each tailwater was statistically evaluated to identify major trends and patterns in the results.
