The Mediterranean region is a climate change hotspot where the rate of exceeds global mean. rapidly changing in combination with an increase anthropogenic pressures cause water resources basin to become increasingly scarce. Modelling future resource availability considering both and changes on karst catchments remains major challenge field hydrology. purpose this study assess relative effects f...
Karst is a hydrogeological environment of importance not only for its water resources potential but also for its scenic and economic potential, thereby increasing the intensity of human impact. The uniqueness of karst in this regard stems from its high sensitivity and vulnerability to imposed pressures and its distinctive response to these pressures. Therefore, a clear definition and formulatio...
The Training Range Environmental Evaluation and Characterization System (TREECSTM) uses average annual hydrologic conditions as inputs for multi-media fate and transport models. This simplification reduces model complexity and data input requirements while providing the capability to conduct long-term predictions of the fate of munitions constituents (MC) as well as other contaminants. TREECSTM...
Karst hydrological investigation of the sinking stream problem of the River Zrmanja is presented. The aim of this analysis is to assess the feasibility of constructing three hydroelectric power plants (HEPP) along the River Zrmanja course. This paper presents a suitable and simple hydrological methodology that can be applied to scarce available data obtained on complex karst terranes. The paper...
Gypsum karst problems in the Permian and Triassic sequences of England have caused difficult conditions for bridge and road construction. In Northern England, the Ripon Bypass crosses Permian strata affected by active gypsum karst and severe subsidence problems. Here, the initial borehole site investigation for the road was supplemented by resistivity tomography studies. The roadway was reinfor...
The major phylogenetic pattern of the cyprinid tribe Labeonini has been revealed by previous molecular studies; however, the relationships within a clade that mainly inhabits the karst regions, which we refer to as the "karst group", in southwest China remain unresolved due to the low taxon sampling. This group includes more than 50% of the genera and species of Labeonini in China. Moreover, mo...
Soil microorganisms play vital roles in recovering and maintaining the health of ecosystems, particularly in fragile Karst ecosystems that are easily degraded after cultivation. We investigated the composition and diversity of soil bacterial communities, based on RFLP and 16S rDNA sequencing, in a cropland, a naturally revegetated land with former cultivation disturbance and a primeval forest i...
The Southwest China Karst, the largest continuous karst zone in the world, has suffered serious rock desertification due to the large population pressure in the area. Recent trend analyses have indicated general greening trends in this region. The region has experienced mild climate change, and yet significant land use changes, such as afforestation and reforestation. In addition, out-migration...

Massif of Parav-Bistoun covered around 880 square kilometers of the thrust zone of Zagros Mountains and located in Kermanshah province. There are various kinds of karst Landforms such as jamas, uvulas', dolines, caves in this mountainous area. These landforms are under the influence of palaeoclimatic conditions. Nowadays, current climatic conditions in this area allows for development of karst ...
