In-Depth Information
This topic focuses on the issue of sustainable use and promotes modeling as a
tool for decision making in the context of the following:
1.
Developing and improving the concept of hierarchical organization of
physical, chemical, and biological environment, which promotes under-
standing of a holistic or ecosystem approach to management for sustain-
ability of natural capital in the coastal lagoon management
2.
Positioning of the lagoon systems within the hierarchy
3.
Establishing the structural dynamic models as a crucial step for research,
monitoring, and integrated management programs of coastal lagoons
4.
Selecting scientific achievements relevant for policy makers, planners, and
practitioners working in the field of sustainable management of the
lagoons and land/seascapes to whom they belong
5.
Unifying a conceptual and operational framework for ecosystem modeling
of coastal lagoons
6.
Integrating sustainable use management principles into the decision-mak-
ing process temporally and spatially

OVERVIEW OF TOPICS
The following guidance is provided to inform readers from various disciplines
and professional work areas about the various topics discussed in the individual
chapters of this topic. As noted above, Chapter 1 briefly identifies the focus of
the topic.
Chapter 2 provides the overall framework for the rest of the chapters. This chapter
defines the organization and functional structural specifications of lagoons. A phi-
losophy of sustainable management is related. The processes of transport, bio-
geochemical cycle, and ecology are described, and the challenges of modeling in
lagoon environments are discussed. Chapter 2 is highly recommended for decision
makers and managers because it is an overview of the key issues that should be
considered in management.
Chapter 3 reviews the physical processes that drive transport in lagoons. Equations
for defining mass, momentum, and energy transfer are presented along with equations
for determining temperature, salinity, and sediment transport. Finally, required input
and boundary conditions and the boundary processes are discussed for lagoon eco-
systems. This material is intended for physical scientists. It presents the reader with
an excellent background on physical modeling of lagoons.
Chapter 4 consists of detailed reviews on biogeochemical cycles (nutrients and
organic chemicals) in lagoons and related processes and mechanisms, special con-
ditions that impact these processes and mechanisms, and the equations used to
formulate these concepts. This information is a sound tool for nutrient and toxic
modeling studies. This chapter is strongly recommended to readers with a particular
interest in understanding the internal dynamics of the lagoons, the impacts of inputs
from the socio-economic system into a lagoon, and the evaluation of lagoon carrying
capacities.
