Managing the Flood Waves from Hemrin Dam

چکیده

Diyala Governorate was exposed recently to high flood waves discharged from Hemrin Dam River when the dam reached its full capacity. The recorded discharge capacity of reduced just 750m3/s. This exposes cities and villages along risk discharging waves, which may reach 3000 m3/s. It is important manage, suggest, design escapes away River. escape branches Lake towards Ashweicha Marsh. One dimensional hydraulic model developed simulate flow within by using HEC-RAS software. Eighty-two cross-sections were extracted digital elevation for used as geometric data. Moreover, thirty utilized Strategic Study Water Land Resources in Iraq. Since passes through two regions different geological formations, roughness coefficients 0.035and0.028were used. Two cases applied3000m3/s, 500 years return period extreme hydrograph Dam, 4000 m3/s, spillway. A spillway proposed at entrance with crest level 105m.a.m.s.l., followed a drop structure eighteen rectangular steps

Rivers dam waves of rabies.

E stablished and emerging infectious diseases of humans and animals are an ever-increasing threat. A key question in disease dynamics is how infection moves in space and time. The most dramatic manifestations of disease spread are waves of infection, often moving across great distances. These waves arise particularly during invasions of pathogens into susceptible territory (1). However, the int...

A Mathematical Model for Forecasting the Dam-Break Flood Routing Process of a Landslide Dam

Once a landslide dam bursts, its reservoir discharges quickly in a flood which will cause catastrophic damage to life and property downstream. For a specific landslide dam, the peak flow rate and the evolution of downstream flood are influenced by the shape and size of the dike breach when dam-break occurs. According to the general nature of landslide dams and field observations of dike-breach ...

Dam-break Flood Risk Management. an Integrated Project

Contemporary dam safety regulations include risk assessment at downstream flood plains and consideration of potential damages due to dam rupture, regardless of the expected probability of occurrence of such event. The aim of these kind of procedures is to increase the safety level along the valley against abnormal floods caused by dam accidents. Emergency plans for downstream flood plains, incl...
