Seismographs near Mount St. Helens Volcano recorded an earthquake swarm lasting nearly 2 months prior to the catastrophic May 18, 1980, eruption. The earthquakes are divided into four classes based on station CPW (Δ = 116 km) seismogram characteristics: (1) events with Sv:P amplitude ratio >3 and dominant frequency >3 Hz; (2) events with Sv:P ratio between 1 and 3 and dominant frequency >2 Hz; (3) events similar to characteristic 2 but with a strong (probably surface wave) phase just after the S phase; and (4) events with frequencies between 1 and 2 Hz lacking a clear S phase. The …
Wasteload Allocation Study Tampa Bay, Florida Vol. Iii Model Validation, B. E. Ross, M. A. Ross, P. D. Jerkins
Wasteload Allocation Study Tampa Bay, Florida Vol. Iii Model Validation, B. E. Ross, M. A. Ross, P. D. Jerkins
Reports
This volume contains documentation of the calibration and verification (validation) of the hydraulic and water quality models used in the wasteload allocation study (WLA) of Tampa Bay, Florida. The first two volumes in this series contain the derivation and theory behind the mathematical formulation and solution techniques. The study was performed for the Florida Department of Environmental Regulation (FDER) by the University of South Florida (USF). The purpose of the study is to evaluate the effects of alternate discharge loading on the water quality of Tampa Bay.

Wasteload Allocation Study Tampa Bay, Florida Statistical Study, Peter Gaitho
Reports
This statistical study was carried out on the Tampa Bay area in an effort to establish some basic relationships between levels of chlorophyl A and various environmental factors. Several statistical analyses were carried out. It was decided to use original data rather than averages over several months. It was felt that this would give us more reliable results. At the outset, the study centered around the use of data from only three months during the year; namely, February, June and October. It was felt that these months would be representative of the seasonal difference. Later, all months of the year …
Wasteload Allocation Study Tampa Bay, Florida Vol. I Hydraulic Model Documentation, B. E. Ross, M. A. Ross, P. D. Jerkins
Wasteload Allocation Study Tampa Bay, Florida Vol. I Hydraulic Model Documentation, B. E. Ross, M. A. Ross, P. D. Jerkins
Reports
This first volume documents the theoretical development and present state of the University of South Florida's two-dimensional, hydraulic, estuary model. It represents the accumulation of 15 years of research and development at the Civil Engineering Mathematical Modeling Center. It has been designed to be completely compatible with a host of other specialty models including a two-dimensional ecologic model, one-dimensional tributary model, salinity model, thermal model, kinetic energy model, and others. Figure 1.2 is a graphical depiction of the compatibility and functionality of various models used with the 2-D hydraulic model.
Wasteload Allocation Study Tampa Bay, Florida Vol. Ii Water Quality Model Doc., B. E. Ross, M. A. Ross, P. D. Jerkins
Wasteload Allocation Study Tampa Bay, Florida Vol. Ii Water Quality Model Doc., B. E. Ross, M. A. Ross, P. D. Jerkins
Reports
This second volume is a documentation of various transport models used at USF. Included, is a comprehensive documentation of the water quality model used in the WLA of Tampa Bay. Documentation of the particle transport and thermal models has been included in addition to the water quality ecological model because the authors wished to provide a historic listing of the more recent or popular transport models relevant to studies in this area.
Wasteload Allocation Study Tampa Bay, Florida Vol. Iv Nutrient Box Model, B. E. Ross, M. A. Ross, P. D. Jerkins
Wasteload Allocation Study Tampa Bay, Florida Vol. Iv Nutrient Box Model, B. E. Ross, M. A. Ross, P. D. Jerkins
Reports
This volume describes the "Box Model" of Tampa Bay that was developed as a part of a Wasteload Allocation Study contract between the Florida Department of Environmental Regulation and the College of Engineering at the University of South Florida. The first three volumes document the development of the validated two-dimensional hydraulic and water quality models that were developed for Tampa and Hillsborough Bays. Development of a "Box Model" represents an experiment in simplification of the solution of what has been an increasingly more complicated field of study.
