Development and technical and economic comparison of design decisions for prevention the entry of the superficial and ground waters to the territory of the Metallurgical terminal of port Ust-Luga

The problem of the paper is drawing up of the project on protection the territory of the Metallurgical terminal of port Ust’-Luga from flooding by the superficial and ground waters. At first, authors gather and analyze materials about topographic, geological and hydrographic situation on above-stated territory and after that made their own territory research.

As a result, to protect Metallurgical terminal from flooding by the superficial and ground waters, it was offered three variants of collectors:

1. Open channel

2. Broken stone absorbing well with punched pipe

3. Broken stone absorbing well

Authors calculate parameters of collectors and compare them. The most suitable collector for port conditions is broken stone absorbing well with punched pipe because of this reliability and compactness.
