In cold (i.e. boreal, subarctic, snowy) climate zones, dynamic groundwater storage is greatly affected by the timing and amount of snowmelt. With global warming, climates in northern hemisphere will transition to temperate. As temperatures rise, dominant type precipitation change from snow rain winter. Further, growing season prolonged. This has a direct impact on aquifer recharge pattern. However, little known about effect changing annual regimes storage. The present work deduces shifting...
Recently, groundwater in Sweden has attracted media attention due to supply shortages caused by dry periods and low levels. About half of Swedish drinking water stems from groundwater. The small aquifers are highly dependent on frequent sufficient recharge. Groundwater recharge forms the link between meteorological drought thus main climate change sustainable supply. This study evaluated whether current knowledge is mitigate impacts change. A review international literature regions with...
Abstract A new concept is proposed for describing, analysing and predicting the dynamic behaviour of groundwater resources based on classification similarity. The makes use ideas put forward by “PUB” (predictions in ungauged basins) initiative surface-water hydrology. One approaches developed PUB uses principle that similar catchments, exposed to weather conditions, will generate a discharge response at catchment outlet. This way, models well-observed catchments can be used make predictions...
In cold climate, the main annual recharge event is spring snowmelt. Projections of groundwater storage hence depend on winter hydroclimate. Winter a factor rain, melt and ground frost. Increases in rain have already been observed. However, due to complex processes involved frost formation its natural patchy coverage, effect poorly understood. The objective study improve understanding connection between hydroclimate Sweden Finland, region with temperate from seasonal cover perspective. study,...
Abstract Visual analysis of time series in hydrology is frequently seen as a crucial step to becoming acquainted with the nature data, well detecting unexpected errors, biases, etc. Human eyes, particular those trained expert, are suited recognize irregularities and distinct patterns. However, there limits what eye can resolve process; moreover, visual by definition subjective has low reproducibility. inspection mentioned publications, but rarely described detail, even though it may have...
Abstract Groundwater drought response to meteorological forcing depends on initial hydrological conditions. This makes it difficult characterise groundwater droughts and identify the vulnerability of aquifers. The objective is increase understanding memory in lowland post-glacial environments. Eighty-one hydrographs are analysed, using standardised level index (SGI) precipitation index. Memory times assessed auto- cross-correlation functions. Response time estimated by comparing two...
