Abstract

Abstract Coupled physical-biological models are capable of linking the complex interactions between environmental factors and physical hydrodynamics to simulate the growth, toxicity and transport of infectious pathogens and harmful algal blooms (HABs). Such simulations can be used to assess and predict the impact of pathogens and HABs on human health. Given the widespread and increasing reliance of coastal communities on aquatic systems for drinking water, seafood and recreation, such predictions are critical for making informed resource management decisions. Here we identify three challenges to making this connection between pathogens/HABs and human health: predicting concentrations and toxicity; identifying the spatial and temporal scales of population and ecosystem interactions; and applying the understanding of population dynamics of pathogens/HABs to management strategies. We elaborate on the need to meet each of these challenges, describe how modeling approaches can be used and discuss strategies for moving forward in addressing these challenges.

Abstract

The presence of all three classes of pathogens (viral, protozoan and bacterial) as well as indicator microbes at a non-point source recreational beach is assessed. The analysis of the various microbes under different targeted environmental conditions has included the evaluation of the sources of microbial contaminants and pathogens and the effectiveness of various analytical methods for microbe detection.

Abstract

Source: https://erdc-library.erdc.dren.mil/jspui/ Prediction of nearshore wave characteristics is an essential part of any study dealing with the determination of littoral transport or longshore currents. Since it is more efficient to determine the deepwater wave as opposed to in shallow water where many points are needed because of bottom effects, it is necessary to transform those deepwater values into shallow-water characteristics. This study reviews the state-of-the-art techniques for transformation of monochromatic surface gravity waves from deep to shallow water over a varying bathymetry. Nonlinear effects are considered and particular emphasis is put on the determination of breaking wave characteristics. For a plane sloping bottom, a new "hybrid" wave theory is introduced which gives improved results for breaking characteristics as compared with existing theories. This hybrid theory uses cnoidal wave height transformation and linear wavelength transformation. Nomographs are presented for easy determination of breaking wave angles and other characteristics such as depth, wave height, and wavelength from given deepwater characteristics and bottom slope.
