Purpose of the Study:
- To detect and map environmental effects of floods in the Halilrood catchment, Kerman province, Iran.
- To utilize flood zone mapping techniques for environmental impact assessment.
- To evaluate the role of the Jiroft dam in mitigating flood impacts.
Main Methods:
- A four-step methodology was employed for flood zone mapping.
- Steps 1-3 focused on calculating and estimating the flood zone map.
- Step 4 involved estimating the environmental effects of flood occurrences.
Main Results:
- Flood zone mapping techniques provided a range of accuracy in estimating environmental effects.
- The Jiroft dam reduced the flood zone from 260 to 225 hectares.
- The dam decreased flood peak intensity by 20%, saving 14% of the flood zone.

Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley.

Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...

Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.

Rapidly varying flow (RVF) in open channels is characterized by abrupt changes in flow depth over a short distance, with the rate of depth change relative to distance often approaching unity. These flows are inherently complex due to their transient and multi-dimensional nature, making exact analysis difficult. However, approximate solutions using simplified models provide valuable insights into their behavior.Key Features of Rapidly Varying FlowRVF is commonly observed in scenarios involving...
