摘要

研究目的分析Wrocław城市中心水系现代化前后的洪水流量。材料与方法利用GIS工具支持的MIKE21数值二维水动力模型。使用历史洪水水文测量数据。给出了选定的水力特征，包括水系通道内的水流分布和两种变量的地下水位剖面，并对投资的影响进行了评估。1997年洪水期间，奥德拉河城市段的最大流量得到了验证。

HYDRODYNAMIC 2D MODEL OF THE CITY CENTRE HYDROSYSTEM OF THE CITY OF WROCŁAW AND ITS FLOOD CAPACITY ANALYSIS

Aim of the study Analysis of flood water flow through the Wrocław City Centre Hydrosystem before and after its modernisation. Material and methods Use of the MIKE21 numerical 2D hydrodynamic model supported by GIS tools. Use of historical floods hydrometrical data. Results and conclusions Chosen hydraulic characteristics were presented, including the distribution of water flow in channels of the hydrosystem and water table profiles for both variants with an evaluation of the investment’s influence. Maximum flow in the city section of the Odra river during the 1997 flood was verified.
