Deuterium and snow hydrology
HDO samples from natural and laboratory snowpacks show that snowpack metamorphism can reduce the initial variability in the HDO content of snow. Field studies in Colorado indicated melt water percolation reduced the variability from a spread of -229%o to -106% relative to Standard Mean Ocean Water …

Continental-scale isotope hydrology
… outlines several applications of isotope hydrology to address four previously unknown questions involving surface- and ground-water resources at regional- to continental-spatial scales over contemporary- to millennial-temporal scales. The four chapters in this dissertation investigate (1) …

Floodplain Hydrology and Biogeochemistry
… was to examine feedbacks between inundation hydrology and floodplain biogeochemistry, with an emphasis on analyzing variation experienced along the river continuum and the cumulative effects of river-floodplain connectivity at the basin scale. This was completed through four independent …

A compendium of Virginia hydrology
Engineers engaged in watersupply or power projects are often faced with the problem of dealing the adequency of the supply, as well as that of the extremes of flow on which the safety of hydraulic structures depends.

The hydrology of debris-covered glaciers
Studies of glacier-hydrology have focused on clean Alpine glaciers, and recently ice sheet outlet glaciers, but there are few studies on debris-covered glaciers. It is known debris affects ablation rates, and that debris-covered glaciers evolve differently to their debris-free counterparts, but how …

Modeling Subglacial Hydrology in the Himalayas
… are all likely strongly affected by subglacial hydrology. Unfortunately, little is known about Himalayan glaciers due to their remoteness and the danger of doing field work there. Recent advances in subglacial hydrological modeling may allow us to shed more light on subglacial processes that …

A circular model of urban hydrology
… The thesis on a circular model of urban hydrology is an attempt in this direction. The thesis is based on the need to develop a sustainable model of urban hydrology. It is a descriptive model that combines existing technologies in a manner that would make them relevant to present and …

Water quality hydrology on surface mined watersheds
Water quality and discharge on four watersheds disturbed by surface coal mining at the Edna Mine in northwestern Colorado have been monito red for about three years. Water quality and discharge have also been monitored in an adjacent stream at points above and below the entrance of mine drainage …

Multi-Scale Modelling of Cold Regions Hydrology
Numerical computer simulations are increasingly important tools required to address both research and operational water resource issues related to the hydrological cycle. Cold region hydrological models have requirements to calculate phase change in water via consideration of the energy balance …

Interactions between hydrology and biogeochemistry within riparian wetlands
Interactions between hydrology and biogeochemistry at various spatio-temporal scales are important control mechanisms within terrestrial and aquatic ecosystems and exist among different compartments and transition interfaces. Understanding the fundamental mechanistic couplings between hydrological …

Applications of Distributed Temperature Sensing in Subsurface Hydrology
Abstract In the study of dynamic subsurface processes there is a need to monitor temperature and groundwater fluxes efficiently in both time and space. Distributed Temperature Sensing has recently become more accessible to researchers in Earth Sciences, and allows temperatures to be measured …

Modelling the Hydrology of the Greenland Ice Sheet
There is increasing recognition that the hydrology of the Greenland Ice Sheet plays an important role in the dynamics and therefore mass balance of the ice sheet. Understanding the hydrology of the ice sheet and being able to predict its future behaviour is therefore a key aspect of glaciological …

Stable isotope hydrology of the Table Mountain group
Rain was collected from 2010 to 2012 at 15 locations around the Cape Fold Belt, at the same time as samples from rivers, springs, seeps and boreholes, totalling 435 samples. Precipitation ranged from -75 ‰ to +40 ‰ for δD and -12 ‰ to +8 ‰ for δ¹⁸O , showing seasonal patterns, with lower δ values …

Modeling the Cumulative Effects of Forest Fire on Watershed Hydrology: A Post-fire Application of the Distributed Hydrology-Soil-Vegetation Model (DHSVM)
The Distributed Hydrology-Soil-Vegetation Model (DHSVM) was applied to the Eightmile Creek watershed in western Montana. The purpose of this research was primarily to assess the applicability of the model as a cumulative effects assessment tool in the post-fire landscape of a forested watershed in …

Near-surface hydrology and hydrochemistry under contrasting land-cover
… was set up. The results indicate that the hydrology was modified in many ways due to land-use change. The most important alteration was the increased importance of the fast flowpath overland flow. Solute exports were in particular linked to the increased volume of overland flow that …
