Download or read book Improved Hydrological Modeling of Great Lakes Basin Including Calibration Period Selection and Rain on snow Simulation written by Daniel Thomas Latimer Myers and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrological models relate landscape and climate characteristics with the water cycle, extreme events, and the availability of freshwater. However, the use of these models can be impaired by common pitfalls including the arbitrary choice of calibration periods and the omission of physical processes such as rain-on-snow melt, making the models less reliable when used where climate or landscape changes are occurring. This dissertation had three objectives: 1) Assess how much water balance simulations can be influenced by the choice of calibration and validation periods, 2) Analyze the influence of rain-on-snow melt of winter floods and summer hydrological droughts in North America's Great Lakes Basin using a modified Soil and Water Assessment Tool (SWAT) hydrological model, and 3) Investigate the influence of climate change on rain-on-snow melt and hydrology of the Great Lakes Basin.We found that the arbitrary selection of calibration periods can substantially influence simulations of water balance components such as snowmelt, surface runoff, and soil water storage. Thus, modelers using this split-sample approach should choose calibration and validation time periods selectively based on knowledge of changes in climate and hydrological characteristics and document the reasons for their choice. We also found that modifying SWAT to include rain-on-snow led to more extreme simulations of winter floods and summer hydrological droughts in the Great Lakes Basin and improved model performance. The unmodified SWAT could be underestimating hydrological extremes in areas where rain-on-snow events occur. Further, the hydrology of the Great Lakes Basin is expected to change throughout the 21st century, including a decrease in annual rain-on-snow melt amount due to reduction in snowpack. Parts of the basin with mean winter/spring air temperatures around freezing were most sensitive to changing rain-on-snow melt. As the threats of climate change and extreme hydrological events become more severe, it is increasingly important for hydrological modelers to best simulate physical processes such as rain-on-snow melt and avoid common pitfalls with the selection of calibration periods.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : The Great Lakes of North America are the largest surface freshwater system in the world and many ecosystems, industries, and coastal processes are sensitive to the changes in their water levels. The recent changes in the Great Lakes climate and water levels have particularly highlighted the importance of water level prediction. The water levels of the Great Lakes are primarily governed by the net basin supplies (NBS) of each lake which are the sum of over-lake precipitation and basin runoff minus lake evaporation. Recent studies have utilized Regional Climate Models (RCMs) with a fully coupled one-dimensional (1D) lake model to predict the future NBS, and the Coordinated Great Lakes Regulating and Routing Model (CGLRRM) has been used to predict the future water levels. However, multiple studies have emphasized the need for a three-dimensional (3D) lake model to accurately simulate the Great Lakes water budget. Therefore, in this study, we used the Great Lakes-Atmosphere Regional Model (GLARM) along with the Large Basin Runoff Model (LBRM) and CGLRRM to predict the changes in NBS and water levels by the mid- and late twenty-first century. GLARM is a 3D regional climate modeling system for the Great Lakes region that is fully coupled to a 3D hydrodynamic lake and ice model. This is the first study to use such an advanced model for water level prediction in the Great Lakes. We found that both annual over-lake precipitation and basin runoff are most likely to increase into the future. We also found that annual lake evaporation is most likely to decrease in Lake Superior but increase in all the other lakes. We posit that the decreases in evaporation are due to decreased wind speed over the lakes and decreased difference between saturated and actual specific humidity over the lakes. Our predicted changes in the three components of NBS would lead to mostly increased NBS and water levels in the future. The ensemble average of our predicted water level changes for Lake Superior, Michigan-Huron, and Erie are +0.14 m, +0.37 m, and +0.23 m by the mid-twenty-first century, respectively, and +0.47 m, +1.29 m, and +0.80 m by the late twenty-first century, respectively. However, due to the multiple sources of uncertainties associated with climate modeling and predictions, the water level predictions from this study should not be viewed as exact predictions. These predictions are unique to our model configuration and methodology. Other studies can easily predict different water level changes through the use of different models and methodologies. Therefore, more predictions from advanced modeling systems like GLARM are needed to generate a consensus on future water level changes in the Great Lakes.

Book excerpt: Accurate values of monthly hydrologic data are required for simulation, forecasting, and water resource studies of the Great Lakes and their basins. This report summarizes the monthly hydrologic data currently used by the Great Lakes Environmental Research Laboratory in their hydrologic and water resources studies of the Great Lakes. The data consist of precipitation, runoff, evaporation, connecting channel flows, diversions, beginning-of-month lake levels, and rates of change in storage.
