andscape Estimates of Habitat Types, Plant Biomass, and Invertebrate Densities in a Georgia Salt Marsh
Habitat Types Plant Biomass Invertebrate Densities
2015/7/16
Salt marshes often contain remarkable spatial heterogeneity at multiple scales across the landscape. A combination of advanced remote-sensing approaches (hyperspectral imagery and lidar) and conventio...
Topographic effects on solar radiation distribution in mountainous watersheds and their influence on reference evapotranspiration estimates at watershed scale
solar radiation distribution mountainous watersheds
2010/12/22
Distributed energy and water balance models require time-series surfaces of the climatological variables involved in hydrological processes. Among them, solar radiation constitutes a key variable to ...
Evaluation of a Precipitation Map Using a Smoothed Elevation-Precipitation Relationship and Optimal Estimates(Kriging)
Precipitation Map Smoothed Elevation-Precipitation Relationship Optimal Estimates
2009/10/28
Using 45 rain gauges, located in the center of French-speaking Switzerland
(approx. 1,600 sq. km), we evaluate an annual mean precipitation map for the
years 1974, 1975 and 1976. This estimate is ba...
Utilization of Satellite Snow-Cover Observations for Seasonal Streamflow Estimates in the Western Himalayas
Satellite Snow-Cover Observations Seasonal Streamflow Estimates Western Himalayas
2009/10/28
The results presented in this study indicate the possibility of seasonal runoff
prediction when satellite-derived basin snow-cover data are related to point
source river discharge data for a number ...
The Importance of Phytoplankton Photoadaptation in Influencing Estimates of Integral Photosynthesis
Phytoplankton Photoadaptation Estimates Integral Photosynthesis
2009/10/27
The rates of light limited (aB) and light saturated (pmaxB) photosynthesis per
unit chlorophyll often showed significant differences between samples collected
from the top and the bottom of the mixe...
Estimating the Variance of Airborne Snow Water Equivalent Estimates Using Computer Simulation Techniques
Airborne Snow Water Equivalent Estimates Simulation Techniques
2009/10/27
Estimates of snow water equivalent derived from measurements of the attenuation
of terrestrial gamma radiation vary as a function of several known sources
of error. In this study, a computer simulat...
The article discusses two statistical methods to estimate PMP values, the
Hershfield and the NERC methods. Neither method offers any explanation
why the PMP values can be calculated by the use of un...
Comparative Model Estimates of Interception Loss in a Coniferous Forest Stand
Comparative Model Estimates Interception Loss Coniferous Forest Stand
2009/10/23
Measurements of throughfall in a coniferous forest stand were analyzed and
compared with model estimates of interception loss using three different types
of models: thc Nordic HBV model, the AMOR mo...
Estimating the Uncertainty in Spatial Estimates of Areal Snow Water Equivalent
Uncertainty Spatial Estimates Areal Snow Water Equivalent
2009/10/23
With the increased demand for water in the United States, particularly in the
West, it is essential that water resources be accurately monitored. Consequently,
the National Weather Servicc (NWS) mai...
Precipitation Estimates over the Baltic Sea:Present State of the Art
Precipitation Estimates Baltic Sea Present State
2009/10/22
Precipitation is one of the main components in the water balance, and probably the component determined with the greatest uncertainties. In the present paper we focus on precipitation (mainly rain) ov...
High-resolution satellite-based cloud-coupled estimates of total downwelling surface radiation for hydrologic modelling applications
total downwelling surface radiative fluxes hydrologic modelling
2009/7/22
A relatively simple satellite-based radiation model yielding high-resolution (in space and time) downwelling longwave and shortwave radiative fluxes at the Earth's surface is presented. The primary a...
Physically based retrieval of crop characteristics for improved water use estimates

The increasing scarcity of water from local to global scales requires the efficient monitoring of this valuable resource, especially in the context of a sustainable management in irrigated agricultur...
The impact of broadleaved woodland on water resources in lowland UK：II. Evaporation estimates from sensible heat flux measurements over beech woodland and grass on chalk sites in Hampshire
broadleaved woodland heat flux water resources chalk sites
2009/5/18
The impact on recharge to the Chalk aquifer of substitution of broadleaved woodland for pasture is a matter of concern in the UK. Hence, measurements of energy balance components were made above beech...

Gravity and Climate Experiment hydrological continental water storage variations
2009/5/8
The estimation of terrestrial water storage variations at river basin scale is among the best documented applications of the GRACE (Gravity and Climate Experiment) satellite gravity mission. In partic...
Estimates of future discharges of the river Rhine using two scenario methodologies: direct versus delta approach
climate change impact regional climate model extreme river flows
2009/5/8
Simulations with a hydrological model for the river Rhine for the present (1960–1989) and a projected future (2070–2099) climate are discussed. The hydrological model (RhineFlow) is driven by meteoro...
