Evaporation, as a major component of the hydrologic cycle, plays a key role in water resources development and management in arid and semi-arid climatic regions. Although there are empirical formulas available, their performances are not all satisfactory due to the complicated nature of the evaporation process and the data availability. This paper explores evaporation estimation methods based o...

Bioretention or rain garden is a preferable low impact development (LID) approach due to its characteristics which reflect natural water cycle processes. However, this system is still little understood and quite complicated in terms of design and implementation due to many technical considerations. Hence, this paper gives a review of the challenges and developments for the use of bioretention f...

The authors propose establishing a hydrologic remote sensing observatory to further advance sensing technologies and their use in scientific inquiry of hydrologic processes. They pose four fundamental questions the answering of which would benefit from a specialized observatory. The questions address issues that range from global needs to monitor changing landscapes and the associate hydrologic...

Abstract Proxy reconstructions and model simulations of precipitation during Earth's glacial periods suggest that the locations mechanisms atmospheric moisture transport have changed considerably past. We investigate hydroclimate Last Glacial Maximum (LGM) using with Community Earth System Model, a focus on extratropics influence rivers (ARs), key driver modern‐day globally. Mean extreme increa...

Mosquitoes and mosquitoborne disease transmission are sensitive to hydrologic variability. If local hydrologic conditions can be monitored or modeled at the scales at which these conditions affect the population dynamics of vector mosquitoes and the diseases they transmit, a means for monitoring or modeling mosquito populations and mosquitoborne disease transmission may be realized. We review h...

Assignment of soils to hydrologic soil groups has been based on published criteria subjectively interpreted and applied by soil scientists. As a result hydrologic soil group placement for any given soil lacks consistency of method and correlation to the respective soil's physical properties. A method of placing soil into hydrologic soil groups was developed using fuzzy systems techniques. This ...
