Abstract The hydrodynamic model is essential for building a water quality rivers, lakes, estuaries, and other systems. Most software, such as HEC-RAS, can perform complex surface body limitations to represent the corresponding area. In contrast, models, like WASP, simulate wide range of contaminants in multidimensional geometry reservoirs. Still, it requires flow information from separate model...

Abstract Extensive impervious area and the man-made streams are characteristics of urban areas. In recent years, rapid urbanization has led to change rural areas into areas, runoff will increase as result spread growth Land use changes, increasing urbanization, unauthorized construction, inefficiency sewage system increased surface in have significant impacts on inundation hazard. Therefore, ma...

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...
