Daily solar radiation, air temperature and rainfall are used in the simulation of the water balance of a Douglas-fir stand for the period April to October – Daily values of net radiation, evapotranspiration, rainfall interception, a water deficit and drainage are by: Recent measurements indicate that the WUE of northeastern U.S. forests has risen steadily with atmospheric CO 2 over the past two decades (Keenan et al. ), probably explaining the unexpected observation that declining actual evapotranspiration from the HB watersheds has accompanied rising temperatures (see Climate Change chapter).
Evapotranspiration and Energy Balance II. Testing two temporal upscaling schemes for the estimation of the time variability of the actual evapotranspiration. A. Maltese; Estimating canopy water content of wetland vegetation using hyperspectral and multispectral remote sensing data. Figure a shows that the mean actual evapotranspiration during the growing season of 80% of the NFSI plots lies between and mm. Plots especially with lower mean evaporation have extreme fluctuations, with up to mm between individual years of the represented period (–). But in half of all years, the fluctuation lies below Author: Heike Puhlmann, Paul Schmidt-Walter, Peter Hartmann, Henning Meesenburg, Klaus von Wilpert.

Earthquakes, ShakeCast, , . estimating changes in the evapotranspiration as a function of leaf area index and soil (rooting) depth. Although other examples of evapotranspiration simulation models can be found for both forested and agricultural systems (e.g. see Spittlehouse and Black, la), the remainder of this chapter has been devoted to examination.

It is often an important variable in estimating actual evapotranspiration (AET) in rainfall-runoff and ecosystem modeling. However, PET is defined in different ways in the literature and. The book concludes with a look at the latest and on-going studies such as this century’s research into controls on methylmercury production and landscape-level carbon storage and cycling.
Covering 50 years of research and written by a veritable who’s who in peatland and forestry science, this important milestone in the collection of. ABSTRACT: Potential evapotranspiration (PET) is an important index of hydrologic budgets at different spatial scales and is a critical variable for understanding regional biological processes.

Year Published: A comparison of models for estimating potential evapotranspiration for Florida land cover types. We analyzed observed daily evapotranspiration (DET) at 18 sites having measured DET and ancillary climate data and then used these data to compare the performance of three common methods for estimating potential evapotranspiration (PET): the Turc method.

Pan data can also be used to estimate the actual ET, representing the ET that occurs when water is limited, for the vegetation of interest using relationships presented by Jensen et al.
Lysimeters, soil water depletion, and the energy balance method have also been used to estimate ET (e.g., van Bavel, ), though measurements are Cited by: 6.
The book's content and scope have been improved and condensed, with updated chapters on the management of forest, woodland, rangeland, agricultural urban, and mixed land use watersheds. Case studies and examples throughout the book show practical ways to use web sites and the Internet to acquire data, update methods and models, and apply the.
In the twentieth century, there was often an unfortunate tendency to treat water-quantity and water-quality issues separately or to dismiss water-quality issues entirely. Although often done only for convenience, this artificial separation masks the importance of water quality in determining what.
It’s influenced by several factors: climate, evapotranspiration, and soil infiltration. These factors can vary by tree species, age, and overall forest structure. As researchers attempt to understand the forest water budget, it is necessary to consider how every step of the water cycle is affected by the variation across forests.

To do so effectively, the chapter also describes the fundamentals of the rainfall-runoff process that these methods attempt to simulate. Evapotranspiration (ET) is a key component of the water balance, which influences hydrometeorology, water resources, carbon and other biogeochemical cycles, and ecosystem diversity.
This study aims to investigate the spatio-temporal variations of ET at the East River watershed in Colorado and analyze the factors that control these variations. ET was acquired Cited by: 3.
Hughes et al. () found the Penman–Monteith approach to be the most reliable method for estimating evapotranspiration from densely vegetated wetlands. Bond et al. () estimated riparian forest evapotranspiration and the areal extent of the riparian zone from the diurnal change of the streamflow rates.

Drained sites are better for timber production – soil trafficability improves and loblolly pine grows faster.The challenge is in estimating the actual evaporation from space, because it also depends on the surface hydrology and biophysical state of the surface.
There are two main categories of satellite-based methodologies to estimate the actual evaporation of water from the land : Thomas R.H. Holmes.
1. Introduction  Quantitative information on evapotranspiration (ET) over large areas from a subcontinental to the global scale is useful for water resource management and climate studies. Spatial distributions of ET at these scales are traditionally estimated with long‐term meteorological or runoff data because the available input data were often limited Cited by:
