Natural disasters, including droughts and floods, have caused huge losses to mankind. Hydrological modelling is an indispensable tool for obtaining a better understanding of hydrological processes. The DEM-based routing methods, which are widely used in the distributed models, sensitive both DEM resolution computational cell size. Too little work has been devoted joint effects size on methods. ...

Estimation of runoff volume and sediment load is a problem that directly affects the performance of dams due to the reduction in the storage capacity of their reservoirs and their effect on dam efficiency and operation schedule. The simulation models can be considered for evaluation of sediment potential if the continuous field measurements are not available. Soil and Water Assessment Tool (SWA...

The single vehicle routing problem with multiple routes is a variant of the vehicle routing problem where the vehicle can be dispatched to several routes during its workday to serve a number of customers. In this paper we propose a goal programming model for multi-objective single vehicle routing problem with time windows and multiple routes. To solve the model, we present a heuristic method wh...

a key parameter for the application of polymer gels in water shut off treatment is the adsorption of polymer gel onto the rock surface. so, the adsorption properties of a nanocomposite hydrogel were discussed in this research by crosslinking of sulfonated polyacrylamide/sodium montmorillonite aqueous solutions with chromium triacetate. the x-ray diffraction patterns indicated that exfoliated ty...

The purpose of this study was to analyze the effect spillway width on flow elevation at weir crest based flood discharge design for Probable Maximum Flood (PMF) return period using routing hydrologically Cacaban Dam (Indonesia). rainfall Precipitation (PMP) uses Hershfield Equation. analysis QPMF used Nakayasu Synthetic Unit Hydrograph (HSS). hydrologic method. is located in Jati Village, Kedun...

In the companion paper to this one (Part I), the Interactions between Soil, Biosphere, andAtmosphere–Total Runoff Integrating Pathways (ISBA-TRIP) continental hydrological system of the Centre National de Recherches Météorologiques is evaluated by using river discharge measurements and terrestrial water storage (TWS) variations derived from three independent datasets of the Gravity Recovery and...

Flood disasters from dam breaks cause serious loss of human life and immense damage to infrastructure and economic stability. The application of Geographic Information System technology integrated with hydrological modeling for mapping flood-inundated areas and depth can play a momentous role in further minimizing the risk and possible damage. In the present study, base terrain data, hydrologic...
