Knowledge about low flow statistics is essential for effective water resource planning and management in ungauged orpoorly gauged catchment areas, especially in arid and semi-arid regions such as Iran. We employed a data set of 20 riverflow time-series from the Iranian Central Plateau River Basin, Iran to evaluate the low-flow series using several frequencyanalysis methods and compared the resu...

the invertebrate communities of the northern chilean rivers are characterised by their marked endemism andspecificity of their community structure in different basins. the river systems located in the atacama desert are endorheicand are affected by the rainy period of january-february commonly known as the “bolivian winter“. the present study isthe first report on the observations of arthropods...

[1] Semi-arid southern California relies heavily on imported water for domestic use. A synthesis of river discharge data in this region reveals that summer (June, July, and August) river discharge in watersheds that have at least 50% urban, suburban, and/or commercial land cover has increased by 250% or more over the past half-century, without any substantial precipitation during these months. ...

The swift fox (Vulpes velox) is a small canid currently listed as endangered in the state of Nebraska. Current and future construction of the Heartland Expressway Corridor (HEC) through the Nebraska panhandle may be a cause for concern for resident swift fox populations. Current swift fox presence along the roadway will be documented before construction continues. We surveyed for swift foxes wi...

Abstract Drought is the most important factor limiting growth and production of wheat in China. Arid semi-arid regions high water consumption agricultural sector have led to various deficit irrigation strategies. The effect hydrological process on yield has been evaluated rainfed cultivation for three climatic stations Gansu Province, Yellow River Valley, A general framework was provided arid r...

The Lower Khazir River provides a good example of changes in river alignment associated with neotectonic movements. The aim of this paper is to address the two following questions: 1How big an impact does the river exert upon the process of (fold) anticline growth? 2Where are the largest geomorphic changes along the lower course of the Khazir River and how are they connected to the sinuosity of...

In hot arid regions where long hot summers are common place, energy consumption represents an aspect of particular concern especially as related to peak load. The selection of the best energy option is a complex function of many various variables and thus represents a multi-criteria decision-making problem. This study involved building a decision-making model in order to optimize energy consump...
