Abstract

Area flooding is the main parameter necessary to achieve hydro technical defense schemes. This can be determined based on calculations performed in various programs. Of the many measures to limit the risk of flooding were chosen for comparison hydrotechnical for protection against floods schemes: embankment and building a polder area. Finally it is noted that structural measures are widely promoted because of the benefits arising from economically and ecologically necessary but complementary structural measures are the only high efficiency in cases with high abundant torrential floods. Today hydro technical schemes are a techno-economic and environmental compromise with fluctuating boundaries, making the decision to be very heavy, plus taking into consideration the temporal variability and the aspect of economy and nature. The optimal solution is specific to each river basin and establishing its methods are different, many of which are listed in this paper.

Highlights

There was hardly a year in which a river is not affected by a form of leakage, either „flood”, whether „high waters”
Regarding impoundment hydro technical scheme for the protection of the unit Jiu-Bechet, flood defense of this unit was made in the early 1960s
Hydro technical scheme is typical of areas from Danube valley and consists of a simple embankment and drainage system necessary to discharges water from the inside (Fig. 1)

Summary

Introduction

There was hardly a year in which a river is not affected by a form of leakage, either „flood”, whether „high waters”. Flood risk management is the application of policies, procedures and practices aiming to identify risks, analyze and evaluate them, treating, monitoring and evaluation in order to reduce their risk so that human communities, all citizens can live and work and to meet the needs and aspirations of a sustainable physical and social environment.
