Risk based urban watershed management under conflicting objectives.
Ecological impairment and flooding caused by urbanization can be expressed numerically by calculating the risks throughout the watershed (floodplain) and along the main stems of the streams. The risks can be evaluated in terms of the present and/or future. This article describes the methodologies for ascertaining the risks in the Geographical Information Systems (GIS) environment. The objective...
متن کاملWatershed-based region merging using conflicting regions
In this paper, we present a method of watershed-based region merging using ‘conflicting regions’ for segmentation of gray level images. It is obvious that both regions and edges in an image give important clues to segmentation in our visual system. So our method uses information from both regions and edges properly. We first obtain initial segments by applying watershed transformation to the im...
متن کاملFinding Efficient Harvest Schedules under Three Conflicting Objectives
Public forests have many conflicting uses. Designing forest management schemes that provide the public with an optimal bundle of benefits is therefore a major challenge. Although a capability to quantify and visualize the tradeoffs between the competing objectives can be very useful for decisionmakers, developing this capability presents unique difficulties if three or more conflicting objectiv...
متن کاملDecathlon, Conflicting Objectives and User Preference Querying
First motivation of our approach is Decathlon as an athletic discipline and its development in the last century (http://www.decathlon.ee). During this period, motivated by a desire of a fair competition, a development in scoring tables occurred. Today we can say it is stabilized. It shows single disciplines ordered (and scored) in direction of better (harder) achievement. Comparison with single...
متن کاملRisk Management Plan in Large Urban Projects
One of the risks distinguishes urban projects from other projects is to purchase of property obstacles. The matter is of more significance in large projects. Issues with regard to possessing property obstacles, lack of accurate layout drawings for underground facilities and following probable changes in designs make it vital to have specific studies on risk management of such projects. So thi...
