The impact of glaciation and climate change on biogeochemical cycling and landscape development
geochemistry phosphorus sediment glacial lake
2015/1/16
Lake cores from Dry Lake, California and Crystal Lake, Illinois were analyzed to identify climate variability and characterize landscape response to glacial/deglacial climate transitions.

WATER BALANCE AND LANDSCAPE DEGRADATION OF AN UNGAUGED MOUNTAIN WATERSHED：CASE STUDY OF THE PICO DE TANCITARO NATIONAL PARK, MICHOACAN, MEXICO
Water balance geographic information system land degradation
2009/10/12
Water balance and its relation to land degradation were investigated by using a spatially distributed model and geographic information system (GIS) in the Pico de Tancitaro National Park, Michoacan, M...
Simulation and validation of concentrated subsurface lateral flow paths in an agricultural landscape
Simulation validation lateral flow paths agricultural landscape
2009/9/11
The importance of soil water flow paths to the transport of nutrients and contaminants has long been recognized. However, effective means of detecting concentrated subsurface flow paths in a large lan...
Landscape elements and river chemistry as affected by river regulation – a 3-D perspective
Landscape elements river chemistry river regulation 3-D perspective
2009/9/11
We tested the hypothesis whether individual land classes within a river catchment contribute equally to river loading with dissolved constituents or whether some land classes act as "hot spots" to riv...
Landscape scale patterns in the character of natural organic matter in a Swedish boreal stream network
Landscape scale patterns natural organic matter stream network
2009/9/11
This paper defines landscape-scale patterns in the character of natural organic matter (NOM) and tests for relationships to catchment soil, vegetation and topography. The drainage network of a boreal ...
Using stable isotope tracers to assess hydrological flow paths, residence times and landscape influences in a nested mesoscale catchment
stable isotope tracers hydrological flow paths
2009/5/18
δ18O measurements in precipitation and stream waters were used to investigate hydrological flow paths and residence times at nested spatial scales in the mesoscale (233 km2) River Feugh catchment in t...
Pattern, process, and function in landscape ecology and catchment hydrology – how can quantitative landscape ecology support predictions in ungauged basins?
catchment hydrology landscape ecology
2009/5/15
The understanding of landscape controls on the natural variability of hydrologic processes is an important research question of the PUB (Predictions in Ungauged Basins) initiative. Quantitative landsc...
Distributed hydrological modeling of total dissolved phosphorus transport in an agricultural landscape, part II：dissolved phosphorus transport
total dissolved phosphorus Soil Moisture Distribution and Routing Model
2009/5/13
Reducing non-point source phosphorus (P) loss to drinking water reservoirs is a main concern for New York City watershed planners, and modeling of P transport can assist in the evaluation of agricultu...
Distributed hydrological modelling of total dissolved phosphorus transport in an agricultural landscape, part I: distributed runoff generation
Soil Moisture Distribution and Routing distributed runoff generation
2009/5/13
Successful implementation of best management practices for reducing non-point source (NPS) pollution requires knowledge of the location of saturated areas that produce runoff. A physically-based, full...
Incorporating landscape characteristics in a distance metric for interpolating between observations of stream water chemistry
stream water chemistry landscape characteristics
2009/5/6
Spatial patterns of water chemistry along stream networks can be quantified using synoptic or "snapshot" sampling. The basic idea is to sample stream water at many points over a relatively short perio...
Hydrologic and landscape changes in the Middle Ebro River (NE Spain)：implications for restoration and management
Middle Ebro River river-floodplain
2009/4/27
The changes of landscape (1927–2003), discharge regime and anthropic activities with the river-floodplain of one reach at the Middle Ebro River (NE Spain) were investigated with the objective to ident...
In this study, it is shown that the complexity of Soil Vegetation Atmosphere Transfer (SVAT) models leads to an equifinality of functional behaviour - many parameterizations from many areas of the par...
Regional-scale hydrological modelling using multiple-parameter landscape zones and a quasi-distributed water balance model
regional-scale spatial variability disaggregation
2009/3/23
Regional-scale catchments are characterised typically by natural variability in climatic and land-surface features. This paper addresses the important question regarding the appropriate level of spati...
Lake landscape position: Relationships to hydrologic connectivity and landscape features
hydrologic connectivity landscape features
2014/4/30
BSTRACT: To improve our understanding of lake landscape position, we compared four metrics based on different aspects of lake surface hydrologic connections: (1) ‘‘lake hydrology,’’...
