the study of karst phenomena and its potentials has had always a particular importance in semi-arid zones of iran, specifically due to the lack of water sources. in this paper, we are going to discuss the landscape morphology in karstic areas, and the way we can have an ecological planning approach to it. maharlu karst basin was selected as the case study of karstic area, and kaftarak mount in ...

By analysing the hydrographs of karst springs it is possible to identify aquifer characteristics and, accordingly, the main features of a karst rock-fissure massif. Consequently, relevant data can be obtained by analysing hydrograph recession curves. This paper presents a detailed analysis and explanation of numerous cases of break points on recession curves via various values of the recession ...

agh darreh tailing dam located in 23 km north of takab, west azarbayjan province is used for disposal of mine tailings. the tailing dam and its reservoir were constructed on gypsiferous marlstones. this is emphasis on geotechnical and environmental importance of the site. although construction of dams on gypsum rocks were not yet prohibited, but the dissolution of gypsum in contact with water i...

In a mature karstic system, the realisation of galleries using the methodology of railway tunnel boring machine (TBM) involves particular problems due to the high risk of interference with groundwater (often subject to remarkable level variations) and with cavities and/or thick fill deposits. In order to define groundwater features it is necessary to investigate both hydrodynamic and karstifica...

Abstract The history of Nordic Hydrology/Hydrology Research is described from its initiation in 1970 to current state 2021. This includes dramatic changes leading first an ownership transformation Association for Hydrology (NAH) 1976, and much later, 2004, a joint between NAH, British Hydrological Society IWA Publishing. development publication policy during time covered as well.

Various approaches can be used to simulate groundwater flow in karst systems, including equivalent porous media distributed parameter, lumped parameter, and dual porosity approaches, as well as discrete fracture or conduit approaches. The purpose of this study was to evaluate two different equivalent porous media approaches: lumped and distributed parameter, for simulating regional groundwater ...

This article presents snow hydrology updates made to iTree-Hydro, previously called the Urban Forest Effects—Hydrology model. iTree-Hydro Version 1 was a warm climate model developed by the USDA Forest Service to provide a process-based planning tool with robust water quantity and quality predictions given data limitations common to most urban areas. Cold climate hydrology routines presented in...
