 Quantitative assessment of landslide sedimentation in the ILAM dam Basin Information on the accurate volume of landslides and sedimentation in landslides is a research necessity, with the assumption that the bulk of sediment accumulated in the ILAM Dam (located between , E and , N) is related to the surface landslides of the basin. Although the role of landslides in erosion, sediment...

there are different methods of reconstructing hydrologic data. depending on the conditions of the station a particular method can produce the best results. generally, in order to estimate the lost data in a station and its surrounding stations, hydrologic, climatologic and/or physiolographic similarities are used. recently, the fuzzy regression method has been used to reconstract the hydrologic...

In the present study, the water quality of Silakhor River, located in Rahim Abad hydrometric station, was analyzed based on Boron, Iron, Nickel, Fluorine, Manganese, Chromium, Cadmium, Aluminum, Copper, Zinc and Lead pollution. The samples were collected from Silakhor River in Rahim Abad hydrometric station during a one-year period, from December 2012 to November 2013. In addition, metal index ...

  Continuous measurement of river discharge is a hard and expensive task in hydrology. To overcome this problem, the stage readings at hydrometric gauges are permanently taken and the discharge of any time at which the actual discharge is unavailable will be estimated through a relationship between discharge and stage. To study the stage-discharge relations and the capability of long-term data ...

This work aims to evaluate the settlement induced by river Tiber groundwater table oscillations. A representative section of subsoil beneath courthouse “Palazzaccio”, close in city centre Rome, is analysed via finite element method with a fully coupled hydro-mechanicalmodel. The effects wetting-drying cycles water oscillation are accounted for adopting Barcelona Basic Model unsaturated layers, ...

Human activities have profoundly changed the hydrological regime and trends of rivers lakes, which, in turn, has affected utilization their navigable conditions. However, few studies focused on effects changes regimes lakes Thus, this study intensively analyzes investigates depth at major control sections lake area during dry season period before 2002, when Three Gorges Reservoir was not yet co...
