《Water and Environment Journal》杂志刊登“降低含水层排泄量水文气象模型复杂性的方法研究”

作者:NazzarenoDiodato, Francesco Fiorillo

刊物:Water and Environment Journal,2013年9月,27卷2期,170–176页

关键词:气候;岩溶区;模型;降水;泉流量

摘要:气候变异导致泉流量年季波动大,尤其是在山区,这是因为山区的地下水主要是由雨水和积雪融化来补给。本研究提出的补给气候模型(DISCLIM),用于开发测试复杂性降低方法,在缺少物理假设的条件下进行历史重构。研究把意大利南部Cervialto山的含水层作为监测点,自20世纪20年代以来就对该岩溶泉进行监测,而且该岩溶泉对气候条件十分敏感。DISCLIM只包含季节性降水和气候指标。尽管非常简单,DISCLIM已经能够对每年水文排泄的波动做出估计,在率定阶段和验证阶段,模型能准确估测地下水排泄年际变化的概率分别为90%和80%,这意味着当缺少水文数据时,DISCLIM可以很容易地用于估算历史时期的补给量。

Complexity-reduced in the hydroclimatological modelling ofaquifer's discharge

Abstract:Climate variability induces considerable interannual fluctuations in spring discharge, especially in mountain areas, where groundwater is recharged mainly by rain and snow melt. This study presents the discharge climatological model (DISCLIM), which was developed to test a complexity-reduced approach to perform historical reconstruction in the lack of physical assumptions. The Mount Cervialto aquifer (Southern Italy) is the test site, where a powerful karst spring is monitored since the 1920s and is very sensitive to climatic conditions. DISCLIM incorporates seasonal precipitation and climate indicators only. Despite its simplicity, DISCLIM has been able to well estimate the yearly fluctuations of discharge hydrological, explaining about 90% of the interannual variability at the calibration stage, and more than 80% at validation stage. This means that DISCLIM can be easily used for estimating the discharge in historical times, when no all the hydrological balance data are available for the purpose.
