Discussion on reasonable subdivision level of watershed for distributed hydrologic model 分布式水文模型亞流域合理劃分水平芻議
For the implementation of the concepts , the xinanjiang hydrologic model has been used 考慮到模型概念的可完成性我們使用了新安江模型。
The main requirements for cm operational conceptual hydrologic model are function development , model calibration , and validation followed by production of forecast runs and analysis of results 功能改進(jìn),模型率定,模型預(yù)報的驗證以及其結(jié)果分析是應(yīng)用概念水文模型所需要的幾個主要部分。
The main requirements for an operational conceptual hydrologic model are function development , model calibration , and verification followed by production of forecast runs and analysis of results 要使概念性水文模型具有可操作性,其最基本的需要就是使預(yù)報結(jié)果分析具有功能的可發(fā)展性和模型的可率定性。
In the second phase of this study , the use of hydrological response units ( hrus ) in conceptual hydrologic models ( e . g . , in the xinanjiang model ) is discussed and its application to the kalu river upper catchment in sri lanka is presented 在研究的第二階段,提出了利用概念性水文模型(新安江模型)對水文響應(yīng)單位進(jìn)行討論,討論流域選擇在斯里蘭卡的kalu河的上游。
As easy as it may appear , the calibration of a conceptual hydrologic model ( chm ) with the intention of identifying a " unique " and " consistent " set of parameters is a tedious task , made complicated by a whole host of problems 概念性水文模型計算的目的是識別出一套獨(dú)一無二的并且前后一致的模型參數(shù),這種計算雖然表面上看來很簡單,但是卻是一項相當(dāng)乏味并且復(fù)雜的工作。
The present study investigates the problems cause by the model structure in the automatic calibration of conceptual hydrologic models and the use of hydrological response units ( hrus ) in chms to improve the model performance via integrated gis approach while keeping the number of basic model parameters and the model structure as original 本文對概念性水文模型自動參數(shù)率定中模型結(jié)構(gòu)方面以及水文響應(yīng)單位( hru )的利用方面導(dǎo)致的問題進(jìn)行了調(diào)查,在保持模型原有結(jié)構(gòu)和基本模型參數(shù)的基礎(chǔ)上通過集成gis提高了模型的精度。
