Automatic Calibration Of Water Quality And Hydrodynamic Model (Ce-Qual-W2), Nasim Shojaei
Automatic Calibration Of Water Quality And Hydrodynamic Model (Ce-Qual-W2), Nasim Shojaei
Dissertations and Theses
One of the most important purposes of surface water resource management is to develop predictive models to assist in identifying and evaluating operational and structural measures for improving water quality. To better understand the effects of external and internal nutrient and organic loading and the effects of reservoir operation, a model is often developed, calibrated, and used for sensitivity and management simulations. The importance of modeling and simulation in the scientific community has drawn interest towards methods for automated calibration. This study addresses using an automatic technique to calibrate the water quality model CE-QUAL-W2 (Cole and Wells, 2013). CE-QUAL-W2 is …
Streamflow Modeling Of Johnson Creek Subwatersheds Using The Precipitation Runoff Modeling System, Theophilus Matthew Malone
Streamflow Modeling Of Johnson Creek Subwatersheds Using The Precipitation Runoff Modeling System, Theophilus Matthew Malone
Civil and Environmental Engineering Master's Project Reports
Johnson Creek, in the Portland, Oregon metropolitan region, has several pollutants on the U.S. Environmental Protection Agency's (EPA) 303(d) list including excess heat, low dissolved oxygen, and harmful bacteria. Understanding streamflow response to precipitation events is an important component to evaluating water quality trends and calculating the Total Maximum Daily Load (TMDL) for pollutants of concern. Investigating the streamflow-precipitation relationship on the subwatershed scale can give insight to the hydrologic response of a given watershed. However, developing rating curves for several subwatersheds can be cost and time prohibitive. The objective of this project was to develop a hydrologic model using …
Towards Improving Drought Forecasts Across Different Spatial And Temporal Scales, Shahrbanou Madadgar
Towards Improving Drought Forecasts Across Different Spatial And Temporal Scales, Shahrbanou Madadgar
Dissertations and Theses
Recent water scarcities across the southwestern U.S. with severe effects on the living environment inspire the development of new methodologies to achieve reliable drought forecasting in seasonal scale. Reliable forecast of hydrologic variables, in general, is a preliminary requirement for appropriate planning of water resources and developing effective allocation policies. This study aims at developing new techniques with specific probabilistic features to improve the reliability of hydrologic forecasts, particularly the drought forecasts. The drought status in the future is determined by certain hydrologic variables that are basically estimated by the hydrologic models with rather simple to complex structures. Since the …
