Exit and Paradise Creek Drainage Area Boundaries, Alaska, 2012

This dataset contains drainage area boundaries for Exit Creek and Paradise Creek in Kenai Fjords National Park, Alaska. A drainage area boundary identifies the land area generating surface water that flows to the network of streams above a particular point. In addition to defining the drainage divide, the drainage area boundary provides a bounding area for determining physical and climatic basin characteristics relevant to hydrology. The drainage area boundaries for Exit and Paradise Creeks were developed to compute stream drainage area, percent cover of glaciers or other land cover types, mean basin precipitation and temperature, and other basin characteristics. The drainage area boundaries for Exit and Paradise Creeks include refined glacier divides that may be used to generate glacier boundaries.

本数据集包含阿拉斯加州基奈峡湾国家公园（Kenai Fjords National Park）内埃克西特溪（Exit Creek）与天堂溪（Paradise Creek）的流域边界。流域边界指的是汇集地表径流并流向某一特定点位以上河网的陆地区域。其除可划定流域分水线外，还可为确定与水文学相关的流域物理与气候特征提供边界范围。本次埃克西特溪与天堂溪的流域边界数据集，旨在计算河道流域面积、冰川或其他土地覆被类型的占比、流域平均降水量与气温，以及其他流域相关特征参数。本数据集所包含的埃克西特溪与天堂溪流域边界已精细化处理冰川分水线，可用于生成冰川边界。
