flood is one of the major natural disasters in iran, which is mostly, affected most parts of the country and caused hazards. therefore, identification of the area with high potential risk of flood occurrence is the main purpose in order to the flood control and reducing its damages. in this research the role of the flood routing in identification of the area with high potential flooding has inv...

This study aims to investigate the different management policies of multi-reservoir systems and their impact on the demand supply and hydropower generation in Great Karun River basin. For this purpose, the semi-distributed simulation-optimization  model of the Great Karun River basin is developed. Also, the multi-objective particle swarm optimization algorithm is applied to optimize the develop...

Introduction. The topography [1] and gravity [2] of the Moon are dominated by the signatures of impact basins and the mascon gravity anomalies contained within. A method of generating higher resolution crustal thickness models by utilizing the symmetry of the basins is here presented, providing a refined view of the subsurface structure of the basins, with a focus on Orientale. The crustal stru...

Eighteen previously unknown martian basins have been detected on Viking photographs. The smallest basins have diameters 50 to 100 km less than the smallest known basins on Mercury or the moon. On the latter two planets and the earth, basin morphology varies with increasing diameter: central peak (CP) basins have both central peaks and fragmentary peak rings; peak ring (PR) basins have only conc...

distribution of the genus chondrostoma in iran, which is mostly known from the caspian sea, tigris river, kor river and esfahan basins was mapped. the kura nase, chondrostoma cyri is reported from armenia, georgia and iran and it is found in the streams and rivers draining to the western coast of the caspian sea from the kuma river in the north southward to the kura and aras river basins in the...

Tectonic setting exerts fi rst-order control on basin formation as refl ected in basin subsidence history. While our approach ignores the effects of fl exural loading and eustatic sea-level change, consistency of backstripped subsidence histories (i.e., with local loading effects of sediment removed) suggests consistent tectonic driving mechanisms in each tectonic setting, with the possible exc...

Foreword The CRC for Catchment Hydrology S2 project 'Managing Disposal Basins for Salt Storage within Irrigation Areas' was based on the premise that disposal basins are 'a fact of life' in the Murray-Darling Basin. Consequently there is a need for guidelines to site, design and manage them to minimise environmental and other problems. However, more than 190 existing basins were built when ther...

In dynamical systems examples are common in which two or more attractors coexist, and in such cases the basin boundary is nonempty and the basins often have fractal basin boundaries. The purpose of this paper is to describe the structure and properties of unbounded basins and their boundaries for two-dimensional diffeomorphisms. Frequently, if not always, there is a periodic saddle on the bound...

Many coastal basins of the Brittany peninsula (France) display a high level of nitrate pollution, nine of them highlighted by the European Commission since 2007, as causing algal blooms in several coastal bays. To precisely diagnose and solve this issue the fluxes of every contributing basin have to be considered. However, this faces a strong data-scarce situation as most of the basins are unga...
