The Cuatro Ciénegas Basin (CCB) is a rare oasis in the Chihuahuan Desert in the state of Coahuila, Mexico. It has a biological endemism similar to that of the Galapagos Islands, and its spring-fed ecosystems have very low nutrient content (nitrogen or phosphorous) and are dominated by diverse microbialites. Thus, it has proven to be a distinctive opportunity for the field of astrobiology, as th...

Advanced oxidation processes (AOPs) have led the way in the treatment of aqueous waste and are rapidly becoming the chosen technology for many applications. In this paper, COD reduction potential of leather tanning industry wastewaters by Electro-Fenton (EF) oxidation, as one of the AOPs, was experimentally evaluated. The wastewater sample was taken from an outlet of an equalization basin in a ...

A variety of management options are used to minimize losses of nitrogen (N), phosphorus (P), and other potential pollutants from agricultural source areas. There is little information available, however, to indicate the effectiveness of these options (sometimes referred to as Best Management Practices, or BMPs) on basin scales. The objective of this study was to assess the water quality effecti...

Conceptual semi-distributed hydrological models are developed for a limited consideration of spatial heterogeneity of hydrological characteristics within a river basin. This heterogeneity can be described by area distribution functions of hydrological characteristics which can be estimated in a most effective way by a Geographical Information System (GIS). It is shown how the application of a G...

water user cooperatives were formed due to consideration to people's empowerment and participation in water investment and management. the purpose of this study was to investigate the mechanisms of development and strengthening of water user cooperatives in the aras river basin. the study population consisted of the management board members of the water user cooperatives in the aras basin in th...

[EN] Run-off management is the main challenge of every big city. Land availability, project timeframe, and financing are several issues regarding run-off implementation, including Indonesia’s Capital City, Jakarta. One engineering tools that used to reduce negative impacts in Jakarta Infiltration Well. Several researches on this topic confirm positive impact building infiltration well small cat...

Tight reservoirs hold a vast natural gas in Ordos Basin, and efficient development of these resources can offset the energy shortage. Due to low-porosity low-permeability, hydraulic fracturing becomes necessary tap its resources. After fracturing, large amount fluid fills pore space near fracture, which will influence production. This study focused on water occurrence tight influencing factors....

In the formulation of scientific water resource management systems and strategies for improving utilization efficiency, effects land use change climate on temporal spatial distribution resources cannot be overlooked. And Hanjiang basin is main source supply to eastern Guangdong southwestern Fujian, China. However, experiencing a significant imbalance between demand. This study investigated spat...

The Kordkanlo Basin, one of the Atrak sub-basins, located in the northeastern of the Ghoochan city, the Khorasan Razavi Province; is situated in Kopet Dagh geologic zone. The overall objective of this study is to evaluate the morphotectonic effects on the drainage network of the basin, using morphometric indicators. In this research, morphometric quantitative indicators of hypsometric integral ...
