To understand the characteristics of severe floods under global climate change, we created a design hyetograph for a 100-year return period. This incorporates a modified ranking method using the top 10 extreme rainfall events for present, near-future, and far-future periods. The rainfall data sets were projected with a general circulation model with high spatial and temporal resolution and used...
abstract natural disasters threatening and endangering human communities has resulted in the study and research of such disasters through the related sciences and present methods of forecasting their behavior with time and place and also from a qualification and quantity viewpoint. to this end, numerous methods for the determination of the maximum flood in various return period has been made av...
comparing non-mesh and sutured inguinal hernia repairs in groin surgery: a randomized clinical trial
purpose: mesh technique is the standard for inguinal hernia repair because of less recurrence, but it is inferior or equal to sutured technique in case of other post-operative complications such as chronic pain. this clinical trial set out to compare these two techniques. materials and methods: a total number of 322 cases of unilateral inguinal hernia in participants older than 18 years...
The paper presents the results of stationary, detailed studies on variability mutual share two fluvial loads, i.e., suspended solids and dissolved material during floods caused by rainstorm, continuous rainfalls snowmelt in selected rivers (Silnica, Sufraganiec) draining small catchments central Poland, including characterized a high level urbanization. Irrespective origin flood, load did not e...
Background: Colorectal carcinoma is considering as a curable disease. Treatment of recurrent cases is hard and sometimes impossible. Evaluation of the rate and affecting factors of recurrence in each hospital would help to decreasing recurrent cases. The aim of this study is evaluation of the rate, clinical and pathologic features, and outcome of recurrent colorectal carcinoma in a referral tea...
Relationships between cataclysmic flood-generated landforms and flood hydraulics were investigated along Box Canyon, an 11 km long bedrock gorge of the lower Big Lost River. Geomorphic mapping along Box Canyon indicates that a cataclysmic flood completely inundated the gorge, resulting in large-scale erosional and depositional features on the adjacent basalt upland. Step-backwater hydraulic mod...
This paper presents a cross-disciplinary framework for assessment of climate change adaptation to increased precipitation extremes considering pluvial flood risk as well as additional environmental services provided by some of the adaptation options. The ability of adaptation alternatives to cope with extreme rainfalls is evaluated using a quantitative flood risk approach based on urban inundat...
Background and objective: Natural disasters have always endangered human lives. Flood is one of the most important natural disasters that impose many damages every year in different parts of Iran. This paper tries to study flood and characteristics of Can watershed in Tehran province. The main purpose of this paper is to consider the challenges of flood management in agriculture and provide app...
