The Wisconsin roots of ground water hydrology.
We can trace the roots of ground water hydrology in the U.S. to Wisconsin at the end of the nineteenth century when there was a remarkable confluence of talent at the University of Wisconsin (now the University of WisconsinMadison), including T.C. Chamberlin, F.H. King and C.S. Slichter. Although none of these men likely would have identified himself as a hydrologist, each did seminal work in g...
متن کاملHydrology and Water Resources 4
CONTENTS • There are apparent trends in streamflow volume—both increases and decreases—in many regions. These trends cannot all be definitively attributed to changes in regional temperature or precipitation. However, widespread accelerated glacier retreat and shifts in streamflow timing in many areas from spring to winter are more likely to be associated with climate change. • The effect of cli...
متن کاملHigh-resolution temporal record of Holocene ground-water chemistry: Tracing links between climate and hydrology
Strontium isotope analysis of precisely dated calcite growth layers in Holocene speleothems from Barbados, West Indies, reveals high-resolution temporal variations in ground-water composition and may provide a new approach to documenting the links between climate variability and fluctuations in the hydrologic cycle such as recharge rates and flow paths. The speleothems grew in a cave that devel...
متن کاملGround Water/surface Water Interactions
A long-term study of four degraded streams in the upper Owens River watershed documented the recovery of riparian habitats and significant improvement in channel morphology in response to grazing strategies, recreation management, and pre-irrigation peak flows. Increased control of livestock distribution, timing of forage use and degree of forage utilization on and near stream banks was designe...
متن کاملGround Water/surface Water Interactions
A baseflow survey of 41 tributary creeks investigated the tiansport of alrazine, nilrate-nitrom chloride and sulfate in two 5,000 ha Jasper County, Iowa watersbeds. The waterskds comprise a long-tam paired shldy to evaluate the effects of largesale conversion of row nop to prairie in Walnut creek watershed compared to highly agricultural Squaw creek watershed. Discharge and chemical concentrati...
