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...

Despite the fact that presence of a heat island over city was established quite long time ago, now there is no versatile algorithm for determination urban intensity. The proposed models either take into account only one or several factors formation an do not consider physical reasons difference in thermodynamic conditions between and countryside. In this regard, it impossible to make forecast d...

detention rockfill dams are an easy and common tool for flood control. due to their coarse pores, the flow in void spaces is turbulent and non-darcy. different relationships introduced by researchers are used to define the hydraulics of the flow within the rockfill materials. the present research is aimed at gaining a better understanding of the differ-ence among these relationships and the sou...

The Davo River, an affluent of the Sassandra like other rivers in Côte d’Ivoire, is subject to anthropogenic activities likely deteriorate its quality which could affect use as drinking water and also health aquatic organisms. This study aims at monitoring temporal evolution physico-chemical waters River Dakpadou hydrometric station. Twelve monthly field missions were carried out sample water, ...

Vehicle crush measurements have typically been done using either offset methods or punctual survey methods such as with a total station or using photogrammetry. While offset grid methods are functional in determining 2-D displacement along the x and y-axis, vertical movement along the z-axis is much harder to achieve. Using a total station to complete crush measurements around a vehicle can yie...
