Introduction
I tend to focus on the interactions between ecological and hydrological processes in the karst critical zones, with a special interest in the role of groundwater processes in mediating hydroecologic function. I employ a variety of research tools across various spatial-temporal scales to gain novel insights into plant-available water sources, plant water-use strategies and its responses to environmental stresses, soil moisture availability, groundwater regimes, and stream-aquifer interactions.

Article
Tourism along river basins benefits both tourists and the economy, but its management necessitates trade-offs between nature-based recreation and ecological functioning. Despite ecosystem services being helpful in managing environmental challenges, there are limited data on the impact of tourism activities on ecosystem functioning across different...
Article
Nature-based tourism has an influence on ecosystem functioning around watercourses, but this influence lacks scientific evidence. Additionally, strategic and operational management of streams necessitates trade-offs between the recreational activities and values of tourists and riparian zone hospitality services. This paper aims to assist environme...
Article
Although environmental illiteracy threatens the functioning of landscapes throughout the world, it is frequently ignored. The traditional wisdom assumes that suspicions will evaporate when the public and government authorities are provided with new information. Despite significant efforts to enhance riparian corridor output, limited data are availa...
Article
Human interventions such as tunnel construction have caused groundwater depletion, which substantially affected the functions of forest tree species and their communities. However, the extent to which tunneling-induced groundwater depletion (TIGD) degrades their function levels at various spatial-temporal scales under varying climate conditions rem...
Article
Transpiration dynamics of karst ecosystems are not conditioned only by the shallow-soil water status, mainly because of the presence of deep-water source pools formed within the underlying bedrock if trees can develop their deep roots to the pools. However, the strength of these relationships and how as well as why they can vary from an area to ano...
Article
The cycling of carbon (C) and nitrogen (N) in karst aquatic systems has been shown to be closely related, with coupled control of dissolved organic carbon (DOC) concentrations through the metabolic pathways of subaquatic communities. However, the coupled CN cycling involving in the transformation of dissolved inorganic carbon (DIC) into DOC has not...

In this research, a standard methodology has been applied to delineate groundwater resource potential zonation based on integrated remote sensing (RS), geographic information system (GIS), and analytical hierarchy process (AHP) techniques in Leylia–Keynow watershed, southwest of Iran. A total of five sets of criteria/factors (including lineament de...

Abstract Sabzab and Bibitalkhone Karst springs are the main discharging points of the Kamarun and Pabdeh karstic anticlines (Asmari dolomite and limestone) in Khuzestan province. The exposed surface of both the anticlines are not sufficient to feed the aforementioned springs. According to the general water balance estimation and the discharge hydro...

Bibitalkhone spring with an average annual discharge of 2 m3/s is one of the important karstic springs in the Southwest of Iran which has a special hydrochemical behavior different from the other karstic springs. This study shows that the dominant water types of the spring are Cl–Na and HCO3–Ca for dry (approximately 8 months of year) and rainy (ab...
Article
The main discharging sources of the Pabdeh karstic anticline in the southwest of Iran are two closely spaced springs called Bibitalkhone and Gariveh. Both springs have emerged about 200 m apart at the trend of a crushed zone resulted from the hidden Pabdeh thrust fault and a contact with salty-gypsum layers. Although superficially similar geologica...

Dissolution of evaporite formations, emergence of salty water springs, and intrusion of deep saline waters are important causes in changing the quality of surface water. The study area is part of the reservoir and downstream of Chamshir Dam, which is located in watershed of the Zohreh River 20 km southeast of Gachsaran City (southwest Iran). To con...

Solubility amounts of gypsum are variable in the presence of water containing dissolved salts, especially sodium chloride (NaCl). In this paper, a study of gypsum dissolution in chloride saline water under controlled laboratory conditions using circulation apparatus is presented. The aim is to understand the influence amount of dissolved NaCl varia...
