Flood hydrograph simulation is affected by uncertainty in Rainfall – Runoff )RR( parameters. Uncertainty of RR parameters in Gharasoo catchment, part of the great Karkheh river basin, is evaluated by Monte–Carlo (MC) approach. A conceptual-distributed model, called ModClark, was used for basin simulation, in which the basin’s hydrograph was determined using the superposition of runoff generated...
Although groundwater resources have long been selected as a safe choice for resolving human water requirements, overexploitation of them, especially at Ardabil plain, has promoted a decrease in the quality and quantity of these resources. One of the significant solutions is to identification of the groundwater potential zones and exploitation of them according to their potentials. The aim of th...
Monitoring of Meteorological and groundwater droughts and determining of the lag time between these two types of droughts in spatial various locations can help in consumption management and protection of the groundwater resources. In this study, spatial and temporal changes of droughts were analyzed using the Standard Precipitation and Groundwater Resource Indices (SPI & GRI) in the northern Ma...
The objective of this study was to evaluate the strategies for groundwater resources management, including competition groundwater pumping, optimal control in groundwater pumping, groundwater use and tax policy, water users' participation in groundwater pumping control, and cooperation among government and water user associations in Narimany plain located in Khorasan Province. Irrigation wate...

In the area of Krško alluvial field, Brežice hydroelectric power plant (BHPP), with its surface water reservoir, was completed in 2017. The new BHPP reservoir dam is located approximately 7 km air distance downstream old nuclear (NEK) dam. NEK built 1970s. primary purpose to provide fresh for cooling reactor. To assess impact newly on groundwater, we performed a series data analyses prior const...
The simulation of the occurrence runoff-generated debris flows can be approached by means hydrological models. In this work, we show that a rainfall-runoff model designed for runoff in headwater rocky basins capture both transit timing first debris-flow surge and its hydrograph. We successfully compared stage hydrograph with simulated two Dolomites.
Quantitative changes in groundwater and crises resulting from uncontrolled water extraction have turned water resources management into one of the supply-demand dilemmas in arid regions. The present study evaluated the quantitative situation of water resources in the Ardestan Plain adjoining the Ardestan desert by using the MODFLOW mathematical model. Simulation of groundwater flow in the stead...
prediction of the heavy metals in the groundwater is important in developing any appropriate remediation strategy. this paper attempts to predict heavy metals (pb, zn and cu) in the groundwater from arak city, using artificial neural network (ann) algorithm by taking major elements (hco3, so4) in the groundwater from arak city. for this purpose, contamination sources in the groundwater were rec...
James C.Y. Guo, PhD, P.E. Professor, Department of Civil Engineering, University of Colorado at Denver, Denver, Colorado 80204. E-mail: [email protected] ___________________________________________________________________________________________ Abstract: A semi-virtual watershed model is presented in this study. This model places the design rainfall distribution on the input layer and t...
