Extended abstract   1- Introduction An examination of the number of floods in recent years shows that floods are no longer a rare sudden disaster, but a growing phenomenon that, at any given time, causes a lot of damage, including life and death. As a result of interference in natural environments, the presence of multiple structures, and the lack of appropriate measures to protect these env...

Background: Magnitude, rate and frequency of the stochastic and unexpected events are of great significance and importance in hydrology. Nowadays, for economic planning of the projects, the use of analytical methods of unexpected events in hydrology is unavoidable. The aim of this study was to compare hybrid regression and multivariate regression to estimate flood peak discharge in the province...

Extended abstract 1- Introduction Flood is one of the most complex and destructive natural phenomena that cause significant damage to agriculture, fisheries, housing, and infrastructure and significantly affects social and economic activities (Chang et al., 2008). The relationship between geomorphological and hydrological parameters makes it possible to predict floods in gauged basins and gen...

   Identifying and determining the flood potential and prioritizing of the flood discharge in the sub-basins is very important in terms of watershed management, flood control and watershed management projects. In many watersheds, it is difficult to investigate and determine the impact of each of the factors and even upstream sub-basins on creating an outlet flood, especially in the sub-basins w...

Khorasan Province is one of the areas in which it is not possible to cultivate farmlands because of low rainfall, and hence, flood farms (bandsar in local dialect) are considered an effective traditional method for flood cultivation in the region. We used a geological map of Birjand at a scale of 1: 250,000 to select the study area. This area includes the city of Birjand and numerous population...

In a natural ecosystem, land exploitation and change in environmental conditions, particularly changes in vegetation and land use effects on hydrological responses such as floods and erosion and sediment and ultimately causing heavy social-economic losses. Then, prediction of effect of land use changes on flood situation in the future decades and sedimentation of watersheds will be the way to d...
