The geometric, sedimentologic and hydrologic attributes of spring-dominated channels in volcanic areas
Carrying capacity ; Channel geometry ; Flood ; Fluvial hydrology ; Idaho ; Montana ; Oregon ; Springs ; Stream ; United States of America
In volcanic areas of Idaho, Oregon and Montana, a number of perennial stream emerge from single springs or zones of springs. The AA. investigate the geomorphic setting, planform, and topography of the spring-dominated channels; the size and nature
of the bed and bank material; and the frequency and duration of flows. The geomorphic and hydrologic attributes of the spring-dominated channels were compared with those of runoff-dominated channels. Finally, they examine whether the distinctive hydrology
of spring-dominated streams was reflected in the fluvial geomorphology of these streams.

1:50 000-scale hydrographic maps were used to inventory crenological objects in the catchment area of the Odra (Oder) with the result that a total of 2611 such objects were mapped. Of these, 1309 are permanent springs, 568 seepages of filtration
springs, 336 marshes, 129 permanent springs with intakes, 111 groups of springs, 87 intermittent springs, 66 mineral springs and 5 observed springs. The total discharge rate from these objects was an estimated 1,645 m3s-1. The discharge rates
of the strongest springs are of nearly 50 l.s-1, though only a few have rates over 20 l.s-1. Upland and lowland areas differ significantly in numbers of crenological objects, but less so in terms of discharge rates (magnitudes of springs). - (BJ)
A Dunantuli-kozéphegység forrasainak természetes hoteljesitménye. (Natural thermal power of springs in the Transdanubian Mountains)
The heated karst water of the Transdanubian Mountains issues in springs on the margins. From the data for the discharges and temperatures of these springs the natural thermal power is calculated (in kW). Fundamental information for 83 springs
Depositional environments of the Florisbad Spring site and surrounds : a revised synthesis
Aeolian features ; Artifact ; Free State ; Geomorphology ; Palaeo-environment ; Palaeozoology ; Sedimentology ; South Africa ; Spring
An investigation of the origins and development of the Florisbad spring led to a broad palaeoenvironmental reconstruction. Particular attention was directed towards the spring mound. The results did not reveal obvious differences with respect
to the sedimentology of lunette dunes in the vicinity and the spring mound itself. The complex history is unravelled with the reworking of the aeolian sediments and faunal remains and Stone Age artifacts. - (AJC)
The Sulphur Spring stage and its place in New World prehistory
Arizona ; Datation radiocarbone ; Etats-Unis ; Géographie historique ; Histoire de la géographie ; Préhistoire ; Site archéologique ; Sulphur Spring stage ; Whitewater Draw
Radiocarbon dates from archaeological sites in Whitewater Draw, Arizona, place the Sulphur Spring stage of the Cochise Culture between 8000 and 10,000 yr B.P., and possibly back to 10,400 yr B.P. Geoarchaeological investigations of Whitewater Draw
do not substantiate an earlier claim that Sulphur Spring stage ground stone artifacts are associated with extinct megafauna, nor the hypothesis that Sulphur Spring stage artifacts are specialized plant processing tools of the Clovis Culture.
This paper discusses the chemical evolution and the recharge elevation of spring water by using major dissolved components and isotopic composition around Asama volcano. In addition the A. will provide the conceptual model of groundwater flow system

This study is part of a program to examine spring plant-climate interactions in the major agricultural regions of eastern North America. The project's obectives were to: 1) document the yearly onset of the spring green wave and associated phenomena
The hot spring deposits near Magyarkút and their paleobotanical analysis (Börzsöny Mountains, Hungary)
Carbonate rock ; Diatom ; Hot spring ; Hungary ; Miocene ; Palaeo-environment ; Palaeobotany ; Palaeontology ; Volcanism
to the researches based on geomorphological and paleobotanical methods, the study assumes that a hot spring activity of postvolcanic origin took place in a time interval during the Middle to Late Miocene, in a subtropical environment. Besides the already known
calcareous spring deposits embedded into the diatomaceous environment, in the side of the Szalamandrás Hill rocks of presumably terrestrial origin were also recognised and described based on the flora present in them. Completing the former knowledge
, the study can claim, that among the hot spring deposits of Magyarkút, the terrestrial deposits of Szalamandrás Hill can definitely be separated from the rock complex of limnic origin - the latter being similar to the spring deposits of the Szokolya Basin
Response of karst springs to climate change and anthropogenic activities : the Niangziguan Springs, China
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 influence 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. Accordingly, the spring discharge data were divided into two phases: pre-1979 and post-1979. Using grey system theory
, a discharge model was estimated for the first phase. Then extrapolating the model and using a water balance calculation, the AA. discerned the respective effects on climate change and human activities on depletion of spring discharge for the second phase.
Since the 1940s and 50s, there have been several researches dealing with karst water springs and the mapping of the continuous karst water level of the Transdanubian Mountains. The karst water level sank because of the intense bauxite and coal
mining between the 1950s and 1980s and it started to increase after the decrease of mining activity. The paper is about the mineral contents and geomorphic properties of karst water springs near a chosen reservoir and authors’ aim was to get some
information about the regeneration process of the karst water reservoir. The geomorphic properties of karst water springs were mapped, using detailed field survey (DGPS) and geomorphic mapping. - (AM)

Late Wisconsin groundwater discharge environments of the southwestern Indian Springs Valley, southern Nevada
This report presents the results of a comparative study of the sedimentologic and faunal evidence from late Wisconsin sediments in the Indian Springs Valley and existing groundwater discharge environments of the Steptoe and Butte Valleys
The well known sulphureous springs are reported both in regional and national geological maps, but detailed studies have been rarely carried out. In this paper the AA. describe the sulphureous waters on the basis of the hydrochemical facies
connected with geolithological characters and structural setting of the springs areas. - (NF)

Hydrogeological studies of springs in the catchment of the Gaula River, Kumaun Lesser Himalaya, India
One result of deforestation in the catchment area of Lesser Himalayan Gaula River area in south-central Kumaun has been the drying up of some springs and the reduced discharge of others. The AA. develop a typology of springs and measure their water
