2. SLM技术的说明

2.1 技术简介

技术定义:

Flood-Control Reservoir - a complex hydraulic facility

2.2 技术的详细说明

说明:

The construction is designed to prevent the flooding of the territory located behind the structure, to eliminate the threat of floods caused by storm rainfall and inappropriate farming, and to reduce flow fluctuation.

Purpose of the Technology: The Svacenický creek polder was built to transform Q100 flood waves.

Natural / human environment: The Svacenický creek polder is part of the flood protection of the area, which is located in the west of Slovakia in the cadastral area of the town of Myjava, in the locality of Tura Luka. The town of Myjava has been plagued by frequent floods in recent years, which have resulted in significant material damage, thereby severely hampering the quality of the local residents´ lives.

6.7 该技术的优点/长处/机会

编制者或其他关键资源人员认为的长处/优势/机会
reduction of catastrophic floods in the Tura Luka profile by approx. 10%
change in the landscape´s structure, provides a new landscape element – a water area and newly constructed accompanying greenery
Minimum flows increased by approx. 10%
The construction of the polder will bring about new and improved conditions for other organisms, as it will create new habitats.

6.8 技术的弱点/缺点/风险及其克服方法

编制者或其他关键资源人员认为的弱点/缺点/风险 如何克服它们?
During the construction and operations arable land will not be usable.
Construction of the polder will create a new water area, but in terms of the technical design, the construction will not affect the water table in the greater area.
The effects on the air quality during the construction are normally associated with an increased risk of dust (construction, transport), but this will have a short-term impact.
There will be a temporary cessation of the use of certain habitats as a result of the taking of the land. It is expected that during the construction, trees will be cut down or damaged or that those habitats that are located in the bank vegetation of the Svacenicky creek and its immediate vicinity will disappear. This activity will affect approx. 0.35% of the entire length of the original riverbed. The taking of the land may result in injury or death to small mammals.
