Near-surface hydrology and hydrochemistry under contrasting land-cover
Human transformation of the Earth’s land surface has far-reaching and important consequences for the functioning of hydrological and hydrochemical processes in watersheds. In nowadays land-use change from forest to pasture is a major issue in particular in the tropics. A sustainable management of …

The seasonal dynamics of Arctic surface hydrology in permafrost environments
… may be associated with longterm changes in surface hydrology. As the ground shifts from a frozen to a thawed state, Arctic lakes display changes in surface extent. Therefore, it has become common practice to explore lake dynamics, using these as indicators of permafrost change; dynamics …

Investigating the surface hydrology of Antarctic ice shelves using remote sensing and machine learning
Surface meltwater is widespread across many of Antarctica’s ice shelves and can contribute towards ice-shelf instability and potential collapse via hydrofracture or militate against potential ice-shelf instabilities by forming drainage systems that export surface meltwater off the ice-shelf edge. …

Geology, surface hydrology, and fish habitat relationships in the upper Shavers Fork drainage basin, West Virginia
Shavers Fork is the mainstem stream of a unique upper elevation watershed located in the Appalachian Plateaus province of West Virginia. Surficial "facies" mapping of in-stream and floodplain-adjacent landforms helped to classify small-scale flow patterns into heterogeneous and homogeneous channel …

Analysis of the surface hydrology of the Greenland Ice Sheet using Sentinel-1 Synthetic Aperture Radar
Surface meltwater on the Greenland Ice Sheet (GrIS) has recently received much attention due to its ability to pond to form features such as firn slush zones and supraglacial lakes. This study uses imagery from the recently launched Sentinel-1 Synthetic Aperture Radar sensors to investigate …

Groundwater Dependence of Aquatic Ecosystems associated with the Table Mountain Group Aquifer
… enables a better understanding of groundwater surface water interactions in the TMG, particularly regarding aquatic ecosystems. It has also highlighted the necessity to do proper impact assessments before proceeding with bulk abstraction from this important aquifer. The results also …

Sensitivity and uncertainty analysis in hydrological modeling: a case study of South Chickamauga Creek watershed using BASINS/HSPF
… (HSPF) model was developed for simulating surface and sub-surface hydrology, and creek flows in the South Chickamauga Creek Watershed, TN. The HSPF model was calibrated against USGS observed data from January 2013 to December 2017 and was validated for the period January 2018 to October …

Development and evaluation of a stream temperature component within the PRMS watershed modeling program
… Modeling System (PRMS) watershed surface hydrology model. This module is based on the solution found in the United States Fish and Wildlife Service Stream Network Temperature model (SNTemp), coupled with PRMS meteorologic and hydrologic inputs. The module is called within PRMS to …

Environmental drivers of coastal evolution
… 2 models the effects of glacial ice retreat on surface hydrology and quantifies resulting effects on fluvial sediment transport, showing that landscape changes that accompany deglaciation shape the evolution of rivers and the delivery of sediment to the coast. Chapter 3 explores interactions …

Intra- and Inter-Seasonal Variability of Supra-Glacial 1 Streams and Lakes over the West Greenland Ice Sheet 2 from High-Resolution Satellite Optical Data
… second only to the Antarctic ice sheet. The surface hydrology of the GrIS plays a crucial role on the surface energy and mass balance budgets of the ice sheet as a whole. Surface water, known as supra-glacial water, is seasonally found in the ablation zone and feeds the en-glacial and …

Hydrological regime changes in a Canadian Prairie wetland basin
The hydrology of the Canadian Prairies has been well described in the scientific literature. 20th C observations show that snowmelt over frozen soils accounted for over 80% of the annual runoff, and streamflow hydrographs peaked in April and ceased in May due to a lack of runoff or groundwater …

A hydrologic calibration of the SWAT model in Kranji Catchment, Singapore
… to expand recreational activities in Singapore's surface waters through the Active, Beautiful, and Clean Waters Program (ABC Waters). One area of concern with ABC Waters is microbial pollution. Pathogens pose an immediate and substantial risk to human health when humans come into contact with …

Modelling the Hydrologic Impact of Land Cover on Stormwater Detention Basins in Harris County, TX
… the impacts of urbanization and the loss of surface storage, the Harris County Flood Control District (HCFCD) built detention basins throughout the county to temporarily store stormwater runoff and release it slowly, lowering peak flows and preventing downstream flooding and erosion. These …

Quantification of the Impact of Supraglacial Lakes and Slush on Surface Energy Balance of Ice Shelves: Nivlisen Ice Shelf, East Antarctica
… are prevalent features of Antarctic ice shelf surface hydrology and efficiently transfer energy to the ice by melt-albedo feedbacks (Dell et al., 2020; Moussavi et al., 2020). There have been few efforts to quantify the energy exchanges between supraglacial meltwater, atmosphere, and ice …
