موضوع این پایانه بررسی شرایط و مسائل زمین شناسی زیست محیطی دشت منوجان (کهنوج)،واقع در جنوب شرقی ایران ،با استفاده سیستم اطلاعات جغرافیایی است. تحلیل خطر لرزه خیزی این شهر با روش های احتمالاتی و تحلیلی مورد بررسی قرار گرفت که نشان از خطر زیاد زلزله دارد. بر اساس نقشه پهنه بندی خطر سیل بخش هایی از شهر ها و روستا ها ی سطح دشت که در مجاورت مسیل های اصلی قرار گرفته اند در معرض این خطر قرار دارند. بر...
An increase in the occurrence of sudden local flooding of great volume and short duration has caused significant danger and loss of life and property in Korea as well as many other parts of the World. Since such floods usually accompanied by rapid runoff and debris flow rise quite quickly with little or no advance warning to prevent flood damage, this study presents a new flash flood indexing m...

landslide like phenomena such as earthquake, flood, and volcano eruption are considered as the important natural events which happen every year in the mountainous and the elevated regions of the country and incur substantial damages and losses. today, in the countries involved with the issue of earthquake sliding, there is an increasing tendency in evaluating and zoning of the danger and damage...
Flood is one of the most devastating natural hazards which lead to the loss of lives, properties and resources. It has therefore become important to create easily read, rapidly accessible flood hazard map, which will prioritize the mitigation effects. This study addresses the need for an efficient and cost-effective methodology for preparing flood hazard maps in Ghana, particularly those region...
There has been an increase in the occurrence of sudden local flooding of great volume and short duration caused by heavy or excessive rainfall intensity over a small area, which presents the greatest potential danger threat to the natural environment, human life, public health and property, etc. Such flash floods have rapid runoff and debris flow that rises quickly with little or no advance war...
rural community and their services, productive activities, because of strong relation with environment, from long bygone were exposed to disastrous natural power. therefore residents of every region by experiment, apply the approaches and measurement to contrast with these events and reduce the damage of them in their community. public attention focused on physical factor and human making envir...
Rivers are the natural flow of surface waters that flow in a certain bed seasonal or permanently. Rivers include a vast range of narrow waterways and with mountainous high steep to low steep and wide beds flowing in plains. However, rivers have had an effective role in urban development and human civilization, therefore, identification of flood prone areas and flood part in the potent lower fie...
Checking a Culvert Suitability for Flood Wave Routing Within the Framework of the EU Flood Directive
Flooding is an international problem that represents the most common and destructive of all weather-related natural hazards. Moreover, man-made interventions such as deforestation, clearance of land and the poor design of hydraulic works such as bridges and culverts can often intensify that risk. This paper demonstrates a complete hydraulic study that was performed in a culvert located in Lofor...
