Discharge from the largest karst spring in north China, the Niangziguan Springs, has been declining since the 1950s. This paper examines the response of these springs to climatic change and anthropogenic infl uence by attempting a model-based discrimination between phases in the stream discharge record. In Niangziguan Springs Basin, the exploitation of karst groundwater began in 1979. According...

The Montes Claros Karst is located on the eastern margin of Bambuí Basin, one covers São Francisco Craton affected by Brasiliano Event, which deformed limestones Lagoa do Jacaré Formation, creating a westward folding system and pair fractures F1 (NNE-SSW) F2 (WNW-ESE). These structures control circulation water in limestone massifs, leading to development karst. main features karst landscape ar...

In 1993, a large radio telescope (LT, now referred as the SKA) was proposed by astronomers from 10 countries at the 24 General Assembly of URSI. The SKA would be a telescope array with a total effective collecting area of about one square kilometer. There are various concepts, worldwide, for realizing the SKA project. Extensive efforts have been made, e.g, by project teams in The Netherlands, A...

Abstract Inspired by structural geology, karstology, geomorphology, as well petroleum coupling excellent documented research works and the field investigation, status prospect for studies on karst feature of Tahe oilfield are discussed comprehensively. Results indicate: (a) majority have appeared since 2000 can be classified three categories 12 subclasses, in which caves, fracture cave systems ...

Some new and poorly known larger benthic foraminifera are described from Middle Jurassic (Upper Aalenian–Bajocian) shallow-water limestones of the Croatian Karst Dinarides. Cymbriaella lorigae FUGAGNOLI is reported for the fi rst time outside its type-locality, the Upper Pliensbachian of the Southern Alps. New taxa described include Bosniella bassoulleti n. sp. and Dubrovnikella septfontainei n...

Where there is sucient water storage in the soil the water potential …Wx† in shoots of Norway spruce [Picea abies (L.) Karst.] is strongly governed by the vapour pressure de®cit of the atmosphere, while the mean minimum values of Wx usually do not drop below ÿ1:5 MPa under meteorological conditions in Estonia. If the base water potential …Wb† is above ÿ0:62 MPa, the principal factor causing wa...
