Mulch Cover and Canopy Effect on Soil Loss

Transactions of the ASAE, 1988
ABSTRACT THE influence of simulated crop canopy cover, canopy height, and straw mulch cover on soil loss was studied in the laboratory. Runoff was significantly reduced by increased mulch cover but was unaffected by canopy cover or canopy height. However, soil loss was significantly reduced by increased mulch cover and also by canopy cover when the ...

Flow over a hill covered with a plant canopy

Quarterly Journal of the Royal Meteorological Society, 2004
AbstractWe develop an analytical model for atmospheric boundary‐layer flow over a hill that is covered with a vegetation canopy. The slope of the hill is assumed to be small enough that the flow above the canopy can be treated within the linear framework of Hunt. Perturbations to the flow within the canopy are driven by the pressure gradient associated

Responses of crustose corallines to epiphyte and canopy cover

Journal of Phycology, 2000
Although a dense cover of epiphytes is generally considered to be harmful for some coralline algae (Corallinaceae, Rhodophyta), crustose corallines in the littoral zone seem to be preserved from bleaching when covered by canopy plants and epiphytes during summer.

Evaporation Studies of Canopy-Covered On-Farm Reservoir

Journal of Irrigation and Drainage Engineering, 2012
AbstractThe present study used fifteen existing evaporation models that use flux gradient, energy balance, and mass transfer approaches to estimate the rate of evaporation from a regular-sized open on-farm reservoir (OFR). Statistical analysis was performed to screen the models.

Measurement and modelling of cloudwater deposition to a snow-covered forest canopy

Atmospheric Environment. Part A. General Topics, 1992
Measurements are presented of the flux of cloud droplets, as a function of particle size to a forest canopy (Sitka spruce) before and after a light snowfall. The results are compared to the predivtions of the model of Slinn. Good agreement is found provided that appropriate values for the effective target diameter are chosen, both before and after the ...

Polygonal plot method for estimating the canopy‐spread cover of shrubs

Proceedings of the Annual Congresses of the Grassland Society of Southern Africa, 1971
An optical method for measuring canopy-spread cover of shrubs is described by means of an illustrated example. Boundaries of plots are hypothetical lines joining the centres of wholly visible shrubs or groups of shrubs surrounding the observation point.

A Rapid Method for Estimating Arboreal Canopy Cover

Ecology, 1967
The per cent of a tract of savannah or woodland that is covered by tree canopy is measured by point quadrat sampling along a series of straight line transects using a vertical viewing tube.

The Treaty Canopy: International Law Covering Forests

2015
Chapter 3 introduced the fragmentation of the international political forest processes and their failure to provide for an international law directly tailored to forests. Due to the apparent lack of an explicit, overall recognition of a common interest with regard to forests, international law is unable to access the regulation of forests directly ...

Assessment of In-situ Canopy Cover Measurement Techniques and GEDI Vertical Canopy Cover in the Indian Western Himalayan Region

Global Ecosystem Dynamics Investigation (GEDI) mission, operating from International Space Station, is a full-waveform LiDAR measuring vertical 3-dimensional structure of terrestrial ecosystems. The vertical canopy cover (CC) available from the GEDI L2B product has applications in forest ecosystem, forest health and climate change studies, and ...

Monitoring urban forest canopy cover using satellite imagery

Environmental Monitoring and Assessment, 1993
The urban forest is being recognized for not only aesthetic benefits but for carbon storage, air filtration, noise reduction and wildlife habitat. This acknowledgment has resulted in actions supporting the urban forest ranging from federal funding of state urban forestry programs to grassroot urban tree planting/advocacy groups.
