摘要:
集水区之地文及水文资讯为水土保持规划设计所不可或缺，本研究系以数值地形模型，利用排水流向之观念，萃取集水区之棱线与水系。撰写程式萃取集水区之面积、周长、河川数量、集水区长度、集水区宽度、形状系数、水系密度、平均高程、平均坡度、集水区密集度、漫地流时间、渠道流时间、集流时间、降雨强度、洪峰流量等属性资料供水土保持规划设计之参考。本系统亦提供动态查询规划区域内任何位置之集水区范围及其属性资料；并可利用道路与河系之交点计算道路沿线各溪流与道路交叉点之位置坐标、河川级序、交点坡度、主流长度、主流平均坡度、河序 1之数量、河川弯曲度、交点之集水面积、交点之集水周长等资讯，供土石流整治及危险溪流划定之参考。
Abstract:
Topographic and hydrologic features of a watershed are the essential information for conservation planning in the watershed.The purpose of this study was to develop a system for extracting the information of interestwatershed.Area,perimeter,rivers,length,mean width, form factor,river density,average elevation,average slope,compactness,time of overland flow,time of channel flow,time of concentration,rainfall intensity and peak flow of analyzed watershed can be derived immediately from the system.A dynamic watershed query module was also developed in the system to show the boundary and attributes of any watershed located in the interestarea.The module of debris can calculate the information ofcoordination,stream order,slope,stream length,average stream slope,numbers of stream order 1,stream tortuosity,watershed area and watershed perimeter of the outlets located atthe intersection of road andstream.The debris module provides useful information for gully control to mitigate the disaster of debris flow.
