landfill site selection is an important action in integrated solid waste management process. different criteria should be considered in site selection. therefore using special methods are necessary to evaluate the criteria. the object of the current study was to determine and select suitable sites for solid waste landfill in shiraz city regarding the observation of environmental matters by usin...

Acoustic seabed classification technologies measure acoustic diversity in the seafloor and surficial substrate. This diversity is generally well correlated with both geology and those benthic species which are keyed to geologic and biotic components of the seafloor. Remote acoustic seabed classification has reached a level of maturity and acceptance in the ocean community such that it should be...

One of the main environmental problem that need efficient software tools is the prediction problem. More concrete, it can mean meteorological prediction, air/soil/water pollution prediction, flood prediction and so on. In the last decade several methods based on artificial intelligence were proposed by taken into account that they can offer more informed methods that use domain specific knowled...

Observations of sea surface height reveal that substantial changes have occurred over the past decade in the mid- to high-latitude North Atlantic Ocean. TOPEX/Poseidon altimeter data show that subpolar sea surface height increased during the 1990s, and the geostrophic velocity derived from altimeter data exhibits declining subpolar gyre circulation. Combining the data from earlier satellites, w...

This paper presents a new approach to extracting hydrographic objects such as rivers, lakes, and other water bodies from digital orthophoto images. A family of directional-sensitive operators is derived and applied to suppress the noise while preserving the desired features. The unique property of this operator family is that boundaries and junctions are preserved with high accuracy while noise...

The forecasting problem is one of the main environmental problems that need efficient software tools. More concrete, it can mean meteorological/weather forecasting, air/soil/water pollution forecasting, flood forecasting and so on. Several methods based on artificial intelligence were proposed by taken into account that they can offer more informed methods that use domain specific knowledge, an...

The eastern region of Morocco is characterized by an arid to semi-arid climate. It often confronted with heavy rainfall episodes that can generate floods cause adverse human and property damage. This work studies hydrological risk in the SidiBoulenouar area (Oujda province) model map areas. method used determine watersheds their watercourses, then calculate flows mathematical formulas. Topograp...
