Download or read book Developing a Watershed Modeling Approach for Reconstructing Past Streamflow in the Upper Walker River Basin California written by Jasmine C. Vittori and published by . This book was released on 2011 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measured streamflow data in a given basin are important for determining regional patterns of climate and streamflow trends, but are often unavailable or extend back less than 100 years. Observed streamflows can be regressed against tree-ring data that serve as proxies for streamflow to extend the measured record, however this empirical approach cannot account for factors that do not directly affect tree-ring growth, but which may influence streamflow. To reconstruct past streamflows in a more mechanistic way, seasonal water balance models were reviewed and developed for the upper West Walker River basin that can use proxy precipitation and air temperature data derived from treering records. The final model incorporates simplistic relationships between temperature, precipitation, and other components of the hydrologic cycle, and operates at a seasonal time scale. The model was able to reproduce streamflow with an r2 of 0.90, and a RMSE of 7.50 cm with average seasonal air temperature as input. Simulated streamflow was 0.66% greater than observed streamflow for WY 1940 through WY 2006. This model was subsequently used to simulate the effects of wildfire on streamflow in the upper West Walker River Basin. The earliest historical record of wildfire in this basin dates back to 1961, with the most recent recorded in 2005. Evapotranspiration and runoff coefficients were adjusted to simulate reduced vegetation cover as a result of fire, and were applied to the dry season when fire was recorded and the subsequent wet season to reflect time required for re-vegetation to occur. The resulting r2 value decreased to 0.85, with RMSE increasing to 9.02 cm, and the overall streamflow simulation increased to 1.57% greater than observed streamflow. Based on the results of this modeling exercise, the modeling approach with average seasonal air temperature would be appropriate for utilizing proxy tree-ring data as input. The model performed very well using only air temperature and precipitation as input and incorporated 6 parameters representing hydrologic processes influencing streamflow. However, simulating wildfire with this model did not improve streamflow simulations, indicating that the model was sensitive to modeling such landcover manipulations.

This book was released on 2014-07-23 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, Fort Worth District; the City of Corpus Christi; the Guadalupe-Blanco River Authority; the San Antonio River Authority; and the San Antonio Water System, configured, calibrated, and tested a watershed model for a study area consisting of about 5,490 mi2 of the Frio River watershed in south Texas. The purpose of the model is to contribute to the understanding of watershed processes and hydrologic conditions in the lower Frio River watershed. The model simulates streamflow, evapotranspiration (ET), and groundwater recharge by using a numerical representation of physical characteristics of the landscape, and meteorologi-cal and streamflow data. Additional time-series inputs to the model include wastewater-treatment-plant discharges, surface-water withdrawals, and estimated groundwater inflow from Leona Springs.

Available in PDF, EPUB and Kindle. Book excerpt: Hydrologic conceptual models are basically mathematical formulation of the different components of the runoff cycle and linked together so that appropriate interactions could occur. The mathematical expressions contains constants which are used as indices. These constants, which are known as input parameters, vary in value when the model is applied to different watersheds. In order to apply a hydrologic conceptual model to a particular watershed, these values should be determined so that reasonable matching of simulated and observed streamflows could be attained. The National Weather Service River Forecast System model, developed by the Hydrologic Research Laboratory, in Silver Spring, Maryland, U.S.A., used in this study, contains twenty-four input parameters to be optimized in order to fit the model to a particular watershed. Initial estimates of five input parameters were made from precipitation, potential evapotranspiration and streamflow records of the Pampanga river basin with outflow point at San Agustin, Arayat, Pampanga. Five parameters were treated as constants and the rest of the twenty-four input parameters were determined by trial-and-error adjustments. Basic computer output for each computer trial which include monthly breakdown of flow componentes, and moisture conditions of various storages, listing and plot of mean daily simulated and observed flow, yearly and multiyear statistical summaries, were analyzed to determine changes of simulated streamflow due to specific input parameter adjustments ...
