Parts 01 and 02 contain full illustration of the hydrologic design of dams using ArcMap and HECHMS software, the design includes the following tasks:

1 Selection of dam's location,
2 Definition of spillway level and crest level,
3 Determining of the reservoir extent,
4 Obtaining the (Elevation Volume) curve of the reservoir,
5 Building the hydrologic model of the dam on the HECHMS software, and
6 Check safety of dam at catastrophic events (high return periods).
