This article focuses on using GIS
as a tool for identifying indicator variables from landscape ecology and
fluvial geomorphology that can be incorporated into decision-making support
models. The geographic unit of focus
involves the watershed catchment scale, with the

Putting water in its place: a perspective on GIS in hydrology and water
management. Hydrological Processes. 12:823±834.
GIS is utilized in hydrology and water management where it often involved modeling and asset management. However, the usefulness of the results is often hindered by the resolution of the data, which in turn brings to the forefront its own set of challenges and problems. This study considered the use of high-resolution spatial data for flood applications. While science tends to focus on GIS priorities in hydrology as they pertain to modeling, resource managers have a different need and use for the tool. While the constraints of GIS often entail the issue of spatial resolution and data quality, there are professional and ethical implications beyond those of technical merit. The flood insurance market illustrates trade-offs involved in determining optimal data scale and resolution, such that identified high risk customers may be deemed uninsurable, and low-risk customers could decide to opt-out from perceived lack of risk. High resolution data can therefore complicate the difficulty of linking premiums to risk. Towards these types of ends, a professional code has been suggested in the application of GIS that clarifies the error, resolution, statistical probabilities, etc. that are inherent in the data utilized in the application decision process. Furthermore, the social implication of increased data and information must be considered, as the application of GIS as a science and decision-support tool has ramifications beyond the development of improved models.

Using
an object-oriented approach, this paper employed GIS to a river basin water
allocation problem. Conceptual
methodology was applied to assist in creating tighter linkages between the
users’ interfaces with the model. The
object-oriented approach the authors advocate consisted of spatial objects and
thematic objects interacting. Thematic
objects represent methods and topics related to the spatial objects. Methods are applied to objects. The authors also distinguish between loose
and tight coupling of GIS and models depending on the sharing or source of the
database information. This paper mostly
dealt with the proper representation, topology, and integration of the data
within the model. It also Some of the
programming directions were also illustrated.
These applications were then applied in a case study model of the

Authors
make the case for more application of GIS capabilities in the field of
aquaculture, which has been relatively slow in deploying such spatial decision
support structures. The particular
focus is on the constraints in application to aquaculture. There is also an overview of GIS terms, and
analytical tools, and methodology that is somewhat useful for non-technical
readers. This portion is basically GIS
101 for this field, but is a very useful summary of the capabilities of
GIS. Four case studies were also presented
in detail to illustrate the application potential for GIS. Some of the applications included
predictions of weather patterns, development potential, and assessments of the
suitability of site locations. The
authors then proceed to discuss the trends they see in GIS regarding fleeter
software development, visualization techniques, and data availability. Overall, this is a very detailed piece
covering the basics of GIS and very specific application methodologies.

This article is the second in a

urban growth processes. GIS provides
one framework to address the need for decision-support by allowing technical,
scientific information to be conveyed in a participatorier manner during the
floodplain management process. GIS
provides the integrating platform for flood policy formation. The combination of GIS and modeling was
evaluated in an urban growth case study located in the

environmental analysis that combines various analytical means for conducting

incorporates physical and ecological factors that influence water quality and

use patterns, the physical habitat, and the macroinvertebrate fauna of streams
in eleven similar watersheds. GIS
contributed a new (relative to the time of the article) way of quantifying
spatial information relative to evaluating distributions and patterns in the
landscape. Authors used land use patterns to quantify critical components of
stream habitat and to assess their impacts on macroinvertebrate assemblages. Sample streams all drained into Lake

Watershed Level. Environment

USGS daily water quality data was
analyzed for electrical conductivity as a water quality indicator in the Great
Miami River of Ohio. Conductivity has a
linear relationship with total dissolved solids in the water. Using GIS, this data was combined with land
use and elevation data so that spatial variation and relationships could be
investigated. Statistical techniques
were employed to determine if significant correlation between land use and
water quality in the catchment existed. Results indicated that conductivity was
not only related to land use and urban development, but also to the cumulative
impacts from upstream sources. Authors
concluded that conductivity therefore might not be the most sensitive indicator
of nonpoint pollution sources. Though conductivity
demonstrated a pattern of increase downstream, the correlations with land use
were weaker with the exception of the correlation between urban land use and
conductivity.
