250 words) The increasing pressure and overexploitation of water bodies in the recent decades are negatively affecting the quality and quantity of aquifers. Its deterioration is also having many negative impacts on numerous ecosystems connected with these water bodies, as is the case of groundwater-dependent ecosystems (GDEs). Therefore, the protection of groundwater resources and ecosystems ar...

Artificial intelligence techniques can be used to solve problems using a heuristic approach. This paper deals with a model able to verify whether there is groundwater in a given place, the quantity available and its quality. The system has been implemented in the logic programming language Prolog and runs on a personal computer under MS-DOS. The knowledge base has been constructed using degrees...

Climate change can result in significant impacts on regional and global surface water and groundwater resources. Using groundwater as a complimentary source of water has provided an effective means to satisfy the ever-increasing water demands and deal with surface water shortages problems due to robust capability of groundwater in responding to climate change. Conjunctive use of surface water a...

in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...

Drought is one of the most complex natural hazards that affect natural systems and different parts of an ecosystem in various ways. Evaluation of drought behavior such as determining the time of its occurrence, understanding the relationships between types of drought, and recognizing its characteristics such as magnitude, severity, and duration of drought periods can be an important aid in wate...
