| Abstract | Loss of precipitation by canopy interception constitutes a substantial portion of the water budget in a forested ecosystem, and accurate models to simulate canopy interception are critical for effective management of forest water resources. We modeled the canopy interception of an evergreen Chinese red pine (Pinus tabulaeformis) forest using the Gash analytical model and the parameterized empirical Fan model and compared the modeled results with directly measured data. Based on 100 rainfall events between 2006 and 2008, the estimated canopy interception ratio was 35.9 % from the Gash model and 53.6 % from the Fan model, compared to 33.2 % from the direct measurement. The differences between measured and modeled values from the Gash model ranged from −0.3 to +7.1 % for different rainfall amounts and from +1.9 to +3.2 % for different years. The Fan model satisfactorily simulated interception for large rainfall events (>50 mm) with differences from −3.4 to +1.3 %, but substantially overestimated interception loss for smaller rainfall events (+21.2 to +37.2 %). The Gash analytical model adequately simulated the canopy interception of Chinese red pine forest. The parameterized Fan model compared favorably to the Gash model in simplicity but not in precision. The Fan model required only incidental precipitation data to run after parameterization, but substantial improvement in modeling precision is needed before it can be used for this forest. |

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.
