Lakes are important stagnant water bodies that protect the ecological integrity of any region, and they have an effective role in maintaining ecosystem. Tödürge Lake, which is karstic, located Sivas Province Turkey. The average depth largest natural lake Province, around 4 m. has a very rich habitat terms flora fauna. Lake its surroundings area should be protected with both environment characte...

Karst groundwater is an important natural resource for the water supply. The karst aquifer systems of Greece are developed within carbonate sedimentary (limestone, dolomite) and metamorphic rocks (marbles) contribute significantly to supply domestic irrigation use. They discharged through springs: submarine, coastal brackish inland freshwater springs. This review presents general characteristic...

Lake Alboraj, located in southeast Spain, was declared natural Microreserve and included into European Natura-2000 Network due to its contribution environmental heritage. Unfortunately, the ecological status of lake has changed dramatically, mainly lowering water table caused by groundwater abstractions for irrigation. It is a permanent small karstic whose surface reduced last decades nearly th...

Abstract. Submarine groundwater discharge (SGD) has received increasing attention over the past 2 decades as a source of nutrients, trace elements and ocean pollutants that may alter coastal biogeochemical cycles. Assessing SGD flows their impact on marine environments is difficult task, since it not easy to identify measure these water discharging into sea. The aim this study demonstrate signi...

Mesta river is a cross-border with Greece, whose catchment area includes parts of Rila, Pirin and the Rhodope Mountains. The karst developed in pre-Paleozoic marble that forms isolated outcrops different basins. largest them two alpine basins located Northern Slavyanka In Rhodopes region, are fragmented embedded non-karstic rocks. They drained from springs relatively low flow rates. drain hydro...

Arenaza Cave is located in Vizcaya (N Spain) and contains important Palaeolithic rock art representations. This cave belongs to an active karstic system developed on Lower Cretaceous limestones, mainly consisting of micrites biomicrites with abundant pyrite moulds. The paintings are made directly the host or thin stalagmitic calcite crusts. limestones this area contain iron ore deposits, which ...

The aims of this paper were to describe seasonal changes in the qualitative and quantitative composition diatom taxa potential application benthic diatoms for ecological status evaluation. Diatom indices (IPS TI) calculated from data three different locations along a longitudinal profile Bunica, small karstic river Bosnia Herzegovina. A total 147 recorded 12 samples. most common Meridion circul...
