An embankment breach is a typical sudden disaster

and the process of breach closure varies with different locations

times

and conditions. It is a systematic emergency project that requires comprehensive decision-making and scientific organization for implementation. In recent years

under the increasing frequency of extreme rainfall and flood disasters

large-scale embankment breaches have occurred more frequently

characterized by severe damage and great difficulty in emergency response. Achieving rapid and efficient closure of large embankment breaches has therefore become an urgent scientific and technological challenge in the field of flood control and emergency rescue. Through case collection

data statistics

and theoretical analysis

this study systematically summarizes the current research status on embankment breach characteristics

closure timing

materials

and technologies. From a new perspective

we comprehensively review the system of pouring (or sinking) materials and its application scenarios. Furthermore

two typical advancement modes are analyzed: continuous rapid advancement and multiple discontinuous advancement

along with practical calculation methods for closing duration. Finally

based on analyses of the hydraulic conditions and morphological characteristics of breaches

we construct a modern technical system for embankment breach closure

and identify future development directions of new rapid closure technologies for complex large breaches. The results provide theoretical support and engineering references for enhancing emergency response capacity in embankment management.
