An Improved Topographic Wetness Index Considering Topographic Position

2010 18th International Conference on Geoinformatics, 2010
The Topographic Wetness Index (TWI) is frequently used to simulate the soil moisture conditions in a watershed quantitatively, and it is the most commonly used indicator for static soil moisture content as well. So it plays an important role in the research of soil erosion and distributed hydrological model in watersheds, etc.

The Use of Multiscale Topographic Position Index for the Identification of Upstream Depressional Wetlands

Wetlands
Abstract: There is increasing evidence that upstream depressional wetlands (UDWs) play a crucial role in regulating catchment hydrology. However, in cultural landscapes, most UDWs have been drained and converted to agricultural land. They are often overlooked in historical wetland inventories due to their small size and degraded ecological state ...

The Modification of Soil Moisture Deficit Calculation Using Topographic Wetness Index to Account For the Effect of Slope and Landscape Position

2012 Dallas, Texas, July 29 - August 1, 2012, 2012
The Sustainable Nutrient Management Decision Support System (SNM-DSS) has been developed to provide farmers with advise on minimising Nitrogen and Phosphorous loss from land spread organic and mineral fertilisers. Within the SNM-DSS, the Hybrid Soil Moisture Deficit (SMD) model (Schulte et al., 2005) is used to assess when slurry spreading is ‘safe ...

The Normative Topographic Position of the Wharton's Duct Orifice in Adults.

Journal of oral and maxillofacial surgery, 2022
PURPOSE We aimed to establish a normative database for the topography of Wharton's duct orifices and to indicate the localization and distances of the orifices against other oral structures.

Land use types and topographic position affect soil aggregation and carbon management in the mountain agro‐ecosystems of the Indian Himalayas

Land Degradation and Development, 2020
The impacts of land use and topographic position can be evaluated through the carbon management index (CMI) that conceptualizes the carbon lability and soil aggregation.

A topographical study of the circadian rhythm in labelling index of mouse gingival and floor-of-mouth epithelium, including changes in labelling activity with individual cell position on the epithelial ridges

Archives of Oral Biology, 1989
A continuous strip of epithelium from the mandibular teeth to the ventral surface of the tongue of B6D2F-1 mice was examined autoradiographically after tritiated thymidine flash-labelling. Five areas were defined: area 1, the gingival sulcus epithelium adjacent to tooth enamel; area 2, the free gingival margin epithelium; area 3, the attached gingiva ...
