Karkheh basin is a flood-prone region in Iran that was severely affected by devastating river floods 2019. This study addressed some of the factors on this event and were emphasized government inquiry committee. These include strategic questions such as effect prior precipitation how dams could mitigate peak volume. well deficits rainfall data led to application Soil Water Assessment Tool model...

Cement grouting is an operation often carried out to consolidate and seal the rock mass in dam sites and tunnels. The quality and efficiency of a grouting operation depends on various factors such as water take, grout properties and grouting pressure. One of the parameters which have the highest effect is pressure since the application of excessive pressure causes the hydraulic fracture phenome...

The Seymareh landslide is the largest rock slope failure (44 Gm3) ever recorded on exposed Earth surface. It detached at ∼10 ka from northeastern flank of Kabir-Kuh anticline (Zagros Mountains, Iran) creating a natural dam responsible for formation lake system that persisted ∼3 kyr during early and mid-Holocene before its emptying phase caused by overflow. chronology demise connection to Holoce...
