discharge hydrograph

The objective of this study is to introduce briefly the basic concept and expression of isotope and the theory of isotopic hydrograph separation,to review the advantages and disadvantages of various hydrograph separation methods which are applied all over the world and to introduce two-component and three-component isotopic hydrograph separation models in details.

简要介绍了同位素的基本概念、表示方法以及同位素示踪流量过程线分割的基本原理。

Test the rationality of assumption which is "contributions of water from the vadose zone must be negligible,or the isotopic content of soil water must be similar to that of groundwater" on hydrograph separation.

通过土壤混合实验和土柱垂向稀释实验,探讨土壤混合与稀释过程中氢氧稳定同位素浓度变化规律,检验应用同位素进行流量过程线分割中一基本假定"土壤水对流量过程线的贡献可以忽略,或者其同位素与地下水相同"的合理性。

It introduces the numerical calculation method of calculating S-hydrograph,unit hydrograph and storm sewer inflow hydrograph with the instantaneous unit hydrograph method,and gives an example of computer program.

用瞬时单位线法求Ｓ曲线，时段单位过程线及雨水管网系统入流流量过程线的计算方法，并给出了计算实例。
