Hydrologic Modeling of Boreal Forest Ecosystems

  title={Hydrologic Modeling of Boreal Forest Ecosystems},
  author={I. Haddeland and Dennis P. Lettenmaier},
This study focused on the hydrologic response, including vegetation water use, of two test regions within the Boreal-Ecosystem-Atmosphere Study (BOREAS) region in the Canadian boreal forest, one north of Prince Albert, Saskatchewan, and the other near Thompson, Manitoba. Fluxes of moisture and heat were studied using a spatially distributed hydrology soil-vegetation-model (DHSVM). 

Technical Report Series on the Boreal Ecosystem-Atmosphere Study (BOREAS)

The BOREAS TE-9 team collected several data sets related to chemical and photosynthetic properties of leaves in boreal forest tree species. Spectral reflection coefficients of the forest understory

Point evaluation of a surface hydrology model for BOREAS

Detailed observations of moisture and energy fluxes made at the Boreal Ecosystem-Atmosphere Study (BOREAS) tower flux sites offer a unique opportunity for the evaluation of hydrological models, since

Modeling annual grassland phenology along the central coast of California

Grassland phenology is an important component of terrestrial biophysical models, with substantial differences in the cycling of energy, carbon, water, and nutrient fluxes between periods of growth

Boreas Hyd-8 1996 Gravimetric Moss Moisture Data

The Boreal Ecosystem-Atmosphere Study (BOREAS) Hydrology (HYD)-8 team made measurements of surface hydrological processes that were collected at the Northern Study Area-Old Black Spruce (NSA-OBS)

BIOME-BGC simulations of stand hydrologic processes for BOREAS

BIOME-BGC is a general ecosystem model designed to simulate hydrologic and biogeochemical processes across multiple scales. The objectives of this investigation were to compare BIOME-BGC estimates of

RHESSys: Regional Hydro-Ecologic Simulation System—An Object- Oriented Approach to Spatially Distributed Modeling of Carbon, Water, and Nutrient Cycling

Process-based models that can represent multiple and interacting processes provide a framework for combining field-based measure- ments with evolving science-based models of specific hydroecological

Assessing the impacts of vegetation heterogeneity on energy fluxes and snowmelt in boreal forests

Aims In the mid- and high-latitude regions, three quarters of the land surface is covered by boreal conifer forests, and snow lasts for 6–8 months of the year. Correctly modeling surface energy

Simulating forest productivity and surface-atmosphere carbon exchange in the BOREAS study region.

Differences between measured and simulated results were attributed to several factors including difficulties associated with measuring nighttime CO(2) fluxes and model assumptions of site homogeneity, however, comparisons between simulations and field data improved markedly at coarser time-scales.



Redistribution of the Canadian Boreal Forest Under a Warmed Climate

A scenario of climate under atmospheric C02 levels double those of the present is used to derive a scenario of corresponding changes in the distribution of boreal forest in Canada. Box's model of the

A global perspective of regional vegetation and hydrologic sensitivities from climatic change

. A biogeographic model, MAPSS (Mapped Atmosphere-Plant-Soil System), predicts changes in vegetation leaf area index (LAI), site water balance and runoff, as well as changes in biome boundaries.

Boreal forests and atmosphere–biosphere exchange of carbon dioxide

The response of vegetation growth to fluctuations in climate or anthropogenic influences is an important consideration in the evaluation of the contribution of land biota to atmospheric CO2

A distributed hydrology-vegetation model for complex terrain

A distributed hydrology-vegetation model is described that includes canopy interception, evaporation, transpiration, and snow accumulation and melt, as well as runoff generation via the saturation

Bioclimatic distribution of vegetation for general circulation model studies

Four global bioclimatic schemes which use climate to determine the distribution of vegetation are evaluated. Only 38% to 40% of the observed land surface, mapped as thirty-one vegetation types, could

Accuracy of precipitation measurements for hydrologic modeling

The use of precipitation data as input for conceptual hydrologic models has enhanced the need for measurements more representative of ‘true’ precipitation. Precipitation input to continuous watershed

Environmental Factors and Ecological Processes in Boreal Forests

This paper reports on the boreal forest, a broad, circumpolar mixture of cool coniferous and deciduous tree species which covers over 14.7 million km{sup 2}, or 11%, of the earth's terrestrial surface, and suggests a possible causal relation, in which the dynamics of the forests at these latitudes regulates the atmospheric carbon concentrations.

Effects of boreal forest vegetation on global climate

TERRESTRIAL ecosystems are thought to play an important role in determining regional and global climate1–6; one example of this is in Amazonia, where destruction of the tropical rainforest leads to

Climatic Control of Vegetation Distribution: The Role of the Water Balance

Improvement in the ability of the water balance to distinguish between climates similar in mean annual energy and water supplies but different in the seasonal timing of the two will help to predict the effects of changing climate on the future distribution of vegetation types.
