Search Symbol (Half-width)	Description of Search Symbols
Space	"AND" indicates the intertwining of key terms used in a search
Double Quotation Marks ("") ( " " )	Double quotation marks indicate the beginning and end of a phrase, and the search will only include terms that appear in the same order of those within the quotations. Example: "image process" ： " image process "
?	Indicates a variable letter. Entering two ? will indicate two variable letters, and so on. Example: "Appl?", search results will yield apple, apply… e , appl y … ( (often used to English word searches) )
*	Indicates an unlimited number of variable letters to follow, from 1~n. Example: Enter "appl*", search results will yield apple, apples, apply, applied, application…(often used in English word searches) e , appl es , appl y , appl ied , appl ication … ( (often used to English word searches) )
AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

Debris flow occurrence is more frequent in central Taiwan, because of its topographic and hydroclimatic characteristics. GIS was used to identify the different characteristics of the 69 gullies which includes the catchment area, stream gradient, stream length, elevation, slope and the use of Inverse Distance Weight (IDW) for rainfall interpolation. The purpose of this study is to determine the debris flow hazard quantitatively with the help of a combination index, as well as topographical and rainfall factors. 
The study area is Chenyulan watershed in Taiwan because of the numerous recorded debris flow occurrence and availability of rainfall data for the chosen period. In July 2001 rainfall brought by Typhoon Toraji triggered a number of debris flow and caused many of casualties and property damages in the watershed. The data of this rainfall event has been used in this study to determine the rainfall intensity and effective accumulated rainfall. The 40-m DTM was used to determine the catchment area, gradients, elevation and stream length.
The result of the topographical and rainfall factors of the 69 gullies were mapped to determine the risk probability using the prediction factor conditions. The relationship of T and R shows that 29% of the total gullies lies in the red zone or the high risk probability of debris flow occurrence. Thus, gullies with high topographical and rainfall factors are likely to have the higher the probability of debris flow occurrence.
