Floods frequently threaten villages near the Khazir River’s floodplains, causing crop losses and threatening residential areas. We used flood-related hydrological software, including WMS HEC-HMS, to study this issue determine how reduce recurrence of flooding. The software can be calculate a hydrograph torrential flows in river drainage basin estimate volume water its flow rates on Earth’s surf...

In hydrological research, flood events can be analyzed by hydrograph coincidence. The duration of the is a key variable to calculate coincidence risk probability and determining whether occurs, while actual neglected in most existing related research. This paper creatively proposes novel method analyze establishing five-dimensional joint distribution volumes, durations interval time for two hyd...

Karst aquifers are often classified as highly heterogeneous systems. Such systems are very complex to assess and model due to the presence of discontinuous porosity, large spatial variability of hydraulic parameters and the difficulties encountered in establishing the fundamental spatial properties of the system. In fact, karst aquifers have been studied and classified into groups based on seve...

Abstract Flood causes great and uncompressible damage to people’s life and properties as well as environment each year in Iran. This research was carried out at the west section of Jazmurian basin that placed in the southeast of Iran. In this research physical characteristics such as area (A), perimeter (Pr), average elevation of basin (av.e), average slope (av.s), gravelious coefficient (G),...

Introduction: Cold temperatures on Mars [1] and a thin atmosphere prevent the occurrence of water in liquid form on the planet. However, sedimentary rocks at Meridiani Terrae show aqueous sedimentation. Catastrophic outgassing due to the Tharsis rise would result in increasing temperature and pressure, enabling water to exist on the surface for short periods of time. Magma–ice interactions duri...
