Gauged catchment with catchment characteristics and at-site estimated flood quantiles in QLD, NSW and VIC, Australia
收藏资源简介:
This repository contains the data (summarized catchment characteristics and flood quantiles) related to the article entitled <em>A Network Approach for Delineating Homogeneous Regions in Regional Flood Frequency Analysis </em>submitted to Water Resources Research. For some selected catchment characteristics, detail description is listed below: tc: time of concentration in hours X =ln(Q) where Q is annual maximum flow in m3/s Mean X = average of X values SD X = standard deviation of X values SKEW X = skewness of X values I62= rainfall intensity (mm/h) for 6 hours duration and 2 years return periods, and so on for I650= rainfall intensity (mm/h) for 6 hours duration and 50 years return periods, MAR = mean annual rainfall (mm) SF = safe factor (no unit) MAE = Mean annual potential evapotranspiration (mm) SDEN = stream density (km/sq km) S1085 = slope of main stream m/km FOREST= fraction forest area in a catchment
本仓库包含与投稿至《水资源研究》(Water Resources Research)的论文《区域洪水频率分析中均质区域划分的网络方法》相关的数据,即汇总流域(catchment)特征与洪水分位数(flood quantiles)。针对部分选定的流域特征,详细说明如下: tc:汇流时间(time of concentration),单位为小时; X = ln(Q),其中Q为年最大流量(annual maximum flow),单位为立方米每秒(m³/s); Mean X:X值的算术平均值; SD X:X值的标准差(standard deviation); SKEW X:X值的偏态系数(skewness); I62:重现期2年、历时6小时的降雨强度(rainfall intensity),单位为毫米每小时(mm/h);同理,I650为重现期50年、历时6小时的降雨强度(mm/h); MAR:年平均降雨量(mean annual rainfall),单位为毫米(mm); SF:安全系数(safe factor),无单位; MAE:年平均潜在蒸散发量(mean annual potential evapotranspiration),单位为毫米(mm); SDEN:河网密度(stream density),单位为千米每平方千米(km/sq km); S1085:主河道坡度(slope of main stream),单位为米每千米(m/km); FOREST:流域内森林面积占比。
