Estimating canopy interception of water by plants during rainfall or sprinkler irrigation is a critical step for evaluating water-use efficiency. Most existing experimental studies and mathematic models of canopy interception have paid little attention to the interception losses of water by herbaceous plants. To better understand the canopy interception processes of herbaceous plants and to est...

Representation of the canopy hydrological processes has been challenging in land surface modeling due to the subgrid heterogeneity in both precipitation and surface characteristics. The Shuttleworth dynamic– statistical method is widely used to represent the impact of the precipitation subgrid variability on canopy hydrological processes but shows unwanted sensitivity to temporal resolution whe...

The aim of this study was to identify the most significant stand parameters affecting net forest precipitation and interception loss in Scots pine stands and to develop multiple linear regression models (MLR) that can be used for practical purposes to predict net forest precipitation and interception rates in northern Germany using forest inventory data and gross precipitation. In the model, th...

forest canopy rainfall interception loss (i), canopy water storage (s), and the ratio of mean evaporation to mean rainfall intensity () are important components of the water balance in arid and semi-arid climate zones. the goal of this project was to quantify i and s and to evaluate the gash interception model for rainfall interception in a mature semi-arid pinus eldarica medw afforestation pla...

Canopy photosynthesis has typically been estimated using mathematical models that have the following assumptions: the light interception inside the canopy exponentially declines with the canopy depth, and the photosynthetic capacity is affected by light interception as a result of acclimation. However, in actual situations, light interception in the canopy is quite heterogenous depending on env...

Canopy interception plays an important role in determining the amount of rainfall reaching the forest floor. During a rainfall event, water either penetrates the canopy falling directly to the understory of the forest floor, or is intercepted by the canopy. From there it can drip to the ground surface, flow down tree stems, or be held and evaporated. The portion that falls directly to the groun...

one of the main components affecting the ecohydrology is interception or loss of rainfall by plant canopy. interception of reduced effective precipitation and dry areas to prevent soil moisture. low level of abstraction is considered as important factors in managing rangeland resources. in this study, the vegetative form, some broad-leaved plants and plant selection and method of abstraction in...
