Preliminary Canopy Removal Experiments in Algal Dominated Communities Low on the Shore and in the Shallow Subtidal on the Isle of Man [PDF]

open access: yes, 1985
The algal dominated communities immediately above and below the low-water spring level on a moderately exposed Manx shore were investigated by canopy removal experiments. Fucus serratus, Laminaria digitata and L. hyperborea were removed.

Delayed rainfall diminishes the positive response of soil respiration to warming

open access: yesGrassland Research, EarlyView.
Warming stimulates soil respiration and its components, while delayed rainfall suppresses them. Crucially, delayed rainfall diminishes or even reverses the positive response of soil respiration to warming by intensifying the drought stress, and autotrophic respiration is more vulnerable than heterotrophic respiration under this interaction.

Unsteady dynamics and organized structures from DNS over an idealized building canopy (In special issue: Urban Climatology ICUC6)

open access: yes, 2007
A numerical study is performed to elucidate the dominant turbulent processes that occur in urban areas. Comprehensive data from direct numerical simulations (DNS) over idealized three-dimensional arrays of buildings are analysed to study the unsteady and

Smart Sensor‐Integrated Lysimeter System for Affordable on‐Farm Crop Water Monitoring and Irrigation Management

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Accurate monitoring of crop water use is critical for precision irrigation, yet conventional lysimeter systems remain too costly and complex for widespread adoption. This study presents the development and field validation of a low‐cost, information and communication technology (ICT)‐enabled weighing lysimeter system that integrates load cells,

CFD-Based Comparative Analysis of Hydronic Piping Layouts for Radiant Cooling System

open access: yesMehran University Research Journal of Engineering and Technology
The radiant cooling system has been reported as energy energy-efficient and cost-effective alternative to conventional air-conditioning. However, limited research has been conducted to evaluate the impact of different piping configurations on the thermal

Drought Risk in Mango and Avocado Orchards: Insights Into Plant Water Relations and Irrigation‐Related Agronomic Solutions

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Climate change is making water availability more uncertain, with growing consequences for the productivity and long‐term sustainability of tropical and subtropical fruit orchards. Mangifera indica L. and Persea americana Mill. both require large amounts of water to sustain growth and productivity.

Canopy structural modeling using object-oriented image classification and laser scanning [PDF]

open access: yes, 2008
A terrestrial laser scanning (TLS) experiment was carried out in the EAGLE 2006 campaign to characterize and model the canopy structure of the Speulderbos forest. Semi-variogram analysis was used to describe spatial variability of the surface.

Drone-based Structure-from-Motion provides accurate forest canopy data to assess shading effects in river temperature models [PDF]

open access: yes, 2019
Climatic warming will increase river temperature globally, with consequences for cold water-adapted organisms. In regions with low forest cover, elevated river temperature is often associated with a lack of bankside shading.

Machine Learning‐Based Estimation of Reference Evapotranspiration and Crop Coefficients for Wheat Under Diverse Climatic Conditions

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Accurate estimation of reference evapotranspiration (ET0) and crop coefficients (Kc) is critical for irrigation planning, particularly in data‐limited regions where agriculture dominates freshwater consumption. Although machine learning (ML) methods have been widely applied to ET0 and Kc estimation, most studies address these parameters ...
