(Formerly GES 230). Theory of underground water occurrence and flow, analysis of field data and aquifer tests, geologic groundwater environments, solution of field problems, and groundwater modeling.
The proposed indexes produced consistent results and showed that a great number of the Monegros wetlands were threatened, regardless of their size or frequency of water occurrence.
The altered river lake interplay hastens low water occurrence inside the lakes which can worsen the drought given shrinking lake sizes in long-term.
In the context of a lack of existing biodiversity inventories for the saladas, we determined their state of conservation and vulnerability using seven physical indicators: escarpment continuity, cropping, stone dumping, size, water occurrence, distance to roads, and proximity to irrigated areas.
Furthermore, the possibility of water occurrence is utterly depended on the local sources of water supply.
On the other hand, areas with low drainage density allow more infiltration to recharge the groundwater and, therefore, have more potential for ground water occurrence.
Sereme (2003) modeled groundwater occurrence and assigned the highest weight of 80 to alluvium and basalt which he considered having more favourable properties for ground water occurrence due to their primary porosities and permeability.
This uncertainty is particularly valid for the inland excess water occurrence in the winter half year, when the increase of evapotranspiration and the significant decrease in the number of frost days can decrease the formation of inland excess waters.
In the same vein, in this modeling, sandstones, schist, and foliated amphibolite were considered to be favourable for ground water occurrence and were given a higher weighting factor among the hard rocks in the study area.
