| Abstract | The growing recognition of trees’ value in urban environments is resulting in increased investment in “green infrastructure.” However, generalizations that deciduous canopies reduce stormwater are based largely on closed-canopy forests, highlighting the need for more detailed study of isolated urban trees. We systematically studied the effect of canopy traits on stemflow percent and funneling ratios for isolated deciduous trees in a semi-arid climate characterized by mostly small precipitation events. High stemflow production was generally associated with high branch angles (single- and multi-leader trees) small diameter-at-breast-height (single-leader trees), furrowed bark in single-leader trees for rain events ≥ 10 mm, and smooth bark in multi-leader trees for all except the lowest rain depth class. Higher numbers of leaders converging at the base were associated with high stemflow yields. Individual-tree stemflow percent and funneling ratio values were variable, even for similar rain depths, suggesting that meteorological factors play a role. Event maximum stemflow percent was 22.8 % (25.6 mm rain depth) for a columnar English oak and event maximum funneling ratio was 196.9 (5.6 mm) for a Riversii European beech. Our findings highlight the importance of infiltration capacity at the base of urban trees and of designing for the rainfall regime when integrating stormwater management with vegetation and soils in cities. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
