Logan 10 m Terrain Analysis

Results from Hydrologic terrain analysis performed on Logan River Basin Digital Elevation model using TauDEM

The input digital elevation model (DEM) is Logan.tif.

The sequence in the script script.py performs a TauDEM analysis that does the following
- Remove pits (by filling them)
- D8 Flow direction
- D8 Contributing area
- Peuker Douglas Valley skeleton
- Weighted D8 contributing area on Peuker Douglas valley skeleton
- Drop analysis to determine objective channel threshold
- Threshold to map stream indicator raster
- Streamnet to produce shapefile of the stream network

Dinfinity analysis for wetness index and height above the nearest drainage (HAND)
- Dinfinity flow direction
- Dinfinity contributing area
- Topographic wetness index
- Distance down to stream in the vertical direction

The file Logan10m.mxd is an ArcGIS map document file for visualizing the results in ArcGIS.

Logan河流域数字高程模型上进行的Hydrologic terrain analysis结果。
输入的数字高程模型（DEM）为Logan.tif。
脚本script.py中的序列执行TauDEM分析，具体操作如下：
- 消除凹地（通过填充）
- D8流向分析
- D8贡献区域分析
- Peuker Douglas山谷骨架
- 基于Peuker Douglas山谷骨架的加权D8贡献区域
- 降流分析以确定目标河道阈值
- 阈值用于绘制河流指示栅格
- Streamnet生成河流网络矢量文件
Dinfinity分析用于湿度指数和最近排水沟以上的高度（HAND）：
- Dinfinity流向分析
- Dinfinity贡献区域分析
- 地形湿度指数
- 垂直方向至河流的距离
文件Logan10m.mxd是ArcGIS地图文档文件，用于在ArcGIS中可视化分析结果。
