drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...

Potentially important contributors to the topography and tectonics of multi-ring impact basins are the thermal contraction and thermal stress that accompany the loss of heat emplaced during basin formation. Heat converted from impact kinetic energy and contributed from the uplift of isotherms during cavity collapse are important components in the energy budget of a newly-formed basin. That the ...

The operational cycle of a storm water quality control basin can be divided into the waiting period between events and the filling and draining period during an event. In this study, an inherent overflow risk is defined as the probability of having a large event exceed the basin storage capacity. Such a probability is prescribed by the basin storage capacity and the local distribution of rainfa...

The safety of a ship is studied using the theory of "safe basin" in this paper. The safe basins of the single degree of freedom (rolling) in waves and winds are investigated. The influences of a static heel angle, waves and winds to the safe basin erosion are examined. It is found that the shape of the safe basin is changed when a static bias angle takes place, and the area of the safe basin de...

Abstract Since eroded sediments are produced from different sources distributed throughout a basin, sediment delivery processes at basin scale have to be modelled by a spatially distributed approach. In this paper a new theoretically based relationship is proposed for evaluating the sediment delivery ratio, SDR{, of each morphological unit, i, into which a basin is divided. Then, using the sedi...

Site U1324 is the westernmost site drilled in the Ursa basin by Expedition 308. Of the three sites in the Ursa Basin, Site U1324 has the thickest sediment loading above the permeable Blue Unit. The principal objectives of drilling Site U1324 were to document rock physical properties at the location of maximal overburden in the Ursa Basin, measure in-situ formation temperature and pressure, docu...

For modeling, the concept of the system and the system boundary is necessary.  The system is defined as a group of objects that in order to fulfill a specific purpose in the framework relationship or interdependence of regularly are interconnected. Systems rainfall - runoff from rainfall in the basin is started and after applying the types of losses (evaporation, infiltration, etc) it will beco...

The Sivas Basin is one of the most well known major Tertiary basins of the Anatolia connected with the evolution of the Neotethyan Ocean. Central Anatolian Thrust Belt contains realms of this ocean and bounds the basin from north. Therefore, realms of the Inner Tauride Ocean are also surrounded the basin from southeast and represented with allochthonous units. Axis of the eastern section of thi...

[1] Spreading in the Adare Basin off north-western Ross Sea (43–26 Ma) and extension in the Victoria Land Basin (VLB, > 36 Ma) are used to constrain the pole of rotation for the Adare Basin, providing a rifting model for the region for the past 45 Ma. The offset from Northern Basin to VLB at about 74 S coincides with the linear Polar-3 magnetic anomaly, inferred to be caused by a major 48 34 Ma...
