Landslide susceptibility mapping using logistic regression analysis in Latyan catchment

    Every year, hundreds of people all over the world lose their lives due to landslides. Landslide susceptibility map describes the likelihood or possibility of new landslides occurring in an area, and therefore helping to reduce future potential damages. The main purpose of this study is to provide landslide susceptibility map using logistic regression model at Latyan watershed, north Iran. I...

Introducing suitable places for establishing rainwater catchment systems in Latyan Watershed

Arid and semi-arid regions with highly variable rainfall and periods of drought or unpredictable floods have severely affected residents' water shortages and they are often living in insecure areas. Rainwater catchment systems are one of the available solutions to overcome water shortage and runoff management in these areas. Surface runoff is a potential source of water that, with proper manage...

modeling gully erosion in dyreh catchment

there are technical and theoretical knowledge of the gully, ditch the clean areas on topographic maps and digital models that will help. however, the ability to use maps (dem) to identify the location and frequency of gully requires knowledge about the process of creating a moat.the present study modeled gulliation prone areas in dyreh river basin done. materials and methods used in this resear...

Teaching Case Studies in Reservoir Siltation and Catchment Erosion*

Waters flowing in streams and rivers have the ability to scour channel beds, to carry particles (heavier than water) and to deposit materials. This phenomenon of sediment transport can affect substantially the design of reservoirs. The paper describes four case studies of siltation which rendered useless water storage structures in less than 25 years. Although each dam had advanced structural f...

Soil erosion and reservoir siltation at catchment scale

A Catchment-Scale Model of Road Erosion and Sediment Delivery

Unsealed roads and tracks are potentially significant sources of diffuse pollutants, particularly sediment. Identifying critical diffuse pollutant sources and their transport potential can greatly improve catchment-scale water quality management. This study describes the application and ongoing development of a road erosion and sediment transport model in the Moruya-Deua and Tuross River catchm...
