Quantifying the effect of non-spatial and spatial forest stand structure on rainfall partitioning in mountain forests, Southern China

The Forestry Chronicle, 2018
Forest stand structure plays an important role in rainfall interception and is a focal point in forest hydrology. Previous studies mainly looked at the effect of non-spatial attributes of stands while a few studies addressed the influence of spatial ...

Mapping rainfall interception for assessing ecological restoration sustainability in China

Environmental Research Letters, 2022
Ecological restoration (ER) programs play an important role in local and global climate change and carbon management policy interventions. Water resource is a key criterion for assessing the sustainability of ERs.

Modeling the Characteristics of Interception Loss in Forests.

Journal of Japan Society of Hydrology and Water Resources, 2002
森林における水循環を考える上で遮断蒸発量を定量的に評価する事が必要となる.そこで本研究では日本とシベリアのアカマツ林とカラマツ林における観測結果をもとに樹冠構成要素を表す指標であるPAI(Plant Area Index)と林内降雨特性の関係を求めた.さらにその関係を用いて降雨の流動過程を連続して的確に把握するためのモデル化を行った.モデルはタンクモデルタイプである.モデルでは林外降雨量,林内降雨量の観測結果からパラメータを決定し,観測値と計算値の遮断蒸発量の検討を行なった.また,林内降雨量の時間変化の検討および,樹液流速度の測定結果から推定された樹冠の乾いた時刻とモデルで推定された時刻との検討を行った.観測結果から,PAIが2.27～4.44の森林での林内降雨量の林外降雨量に対する割合は66～86%

Impact of landuse change on ecohydrological function of canopy in Brant`s oak (Quercus brantii Lindl.) forest in Ghale-gol watershed, Lorestan [PDF]

تحقیقات جنگل و صنوبر ایران, 2016
Ecohydrological functions of canopy are significantly influenced by landuse change. This study was conducted across four current landuse types within the Gale-gol watershed (Khorramabad, Lorestan), including semi-natural forest, disturbed forest, forest ...

Rainfall interception using the revised Gash analytical model for Pinus sylvestris var. mongolica in a semi-humid region of NE China

Ecological Indicators, 2022
Rainfall loss by canopy interception comprises a substantial portion of the water budget in forested ecosystems, and accurately measuring and simulating this process is critical for the effective management of forest water resources. Pinus sylvestris var.

Throughfall, stemflow, and rainfall interception in a natural pure forest of chestnut-leaved oak (Quercus castaneifolia C.A. Mey.) in the Caspian Forest of Iran [PDF]

Annals of Forest Research, 2012
In forest ecosystems, rainfall is partitioned by forest canopies intothroughfall (TF), stemflow (SF), and interception loss (I). In the present study the partitioning of rainfall was studied in a natural chestnut-leaved oak (Quercus castaneifolia C.A.Mey)

Predictive models for stemflow and throughfall estimation in four fruit tree species under hot and sub-humid climatic region

Hydrology Research, 2020
Inclusion of stemflow and throughfall processes in rainfall-runoff modelling requires reliable models for their estimation. In the present paper, stemflow and throughfall generation processes were investigated in relation to rainfall, and morphological ...

Estimation of interception loss from forests by using LAI

2015 Fourth International Conference on Agro-Geoinformatics (Agro-geoinformatics), 2015
Water production is simply a function of precipitation and evapotranspiration (ET). It is essential to quantify ET and/or its components in regional scale for water resources assessments or functional forest plans. Several models that combine empirical equations, field measurements and remote sensing data have been tested and proposed to achieve this ...
