Pipeline crossings of streams, whether large or small, must consider the ability of the stream channel to scour its bed and erode its banks. Case studies are presented to illustrate the kinds of dynamic environments which must be considered in designing pipeline stream crossings. These characteristics may be determined through the use of comparative historical aerial photography and site photographs and surveys. The case studies presented as examples in this paper include gullies, bedrock-lined channels, entrenched meandering streams, multi-channel wandering streams, degrading channels, alluvial fans, and major channels affected by regulation and man-made structures. Natural hazards such as debris jams and beaver dams are also discussed. For each case study, the characteristics of the channels are described, the design approach discussed and site-specific constraints presented which affected the final design.

Geotourism is defined as tourism that involves protection of geographical features, environment, culture, aesthetic and heritage of the places that are visited and bring prosperity to its citizens. the importance of geomorphosites in tourism sustainable development, different researches have been done around the world in recent decades Khorramabad county is located in Lorestan province in the southwestern Iran. It has a high potential to attract domestic and foreign tourists owing to its geographical location, climate, topography and geological specific conditions. In this paper, 39 sites were also studied using field observations and available information, and then 8 sites were chosen and ranked using Rocha model (2014), fieldwork and experts' viewpoint and researches of this study. Finally, assessment of 8 geomorphosites was done using a suitable model for the study area. According to the assessment of 8 geomorphosites, Makhmalkooh was selected with high score and Salt mines have earned the lowest score. Also, the results showed that most of the selected geomorphosites have good infrastructure and are approximately near to the urban settlement.
