Abstract. Monitoring the water movements in karstic areas is a fundamental but challenging task due to complexity of drainage system and difficulty deploying network observations. Gravimetry offers valid complement classical hydrologic measurements order characterize such systems which recharge process causes temporarily accumulation large volumes voids epi-phreatic system. We show an innovativ...

According to the Water Framework Directive (WFD), biological quality elements constitute basis for assessing ecological status of surface waters. Biological communities are good indicators water because they reflect environmental conditions over time and do not require frequent sampling. The main aims were assess trophic Lake Visovac (Krka River hydrosystem, South Croatia) using phytoplankton t...

A field-mapping and crystal-chemical study of two aluniteand halloysite-rich deposits in the Turplu area, situated northwest of Balıkesir on the Biga Peninsula of northwest Turkey reveals a mineralogically diverse and a potentially economic clay deposit. The mineral assemblage along fault zones is dominated by halloysite and sometimes alunite. The alunite is nearly end-member in composition (a ...

The technique of stable hydrogen and oxygen isotope tracing has become an important means to study the mechanism water movement due its high sensitivity traceability. In this study, four dominant tree species in karst forest Maolan, Guizhou Province, were selected, their water-use strategies maintenance diversity investigated using technique. results show that: (1) regional precipitation varied...

Wuhan (China) is facing severe consolidation subsidence of soft soil and karst collapse hazards. To quantitatively explore the extent causes land in Wuhan, we performed multitemporal interferometry (MTI) analysis using synthetic aperture radar (SAR) data from TerraSAR-X satellite 2013 to 2017 Sentinel-1A 2015 2017. MTI results reveal four major zones namely, Hankou (exceeding −6 cm/yr), Xudong-...
