Comparison of groundwater recharge estimation methods for the semi-arid Nyamandhlovu area, Zimbabwe

Estimation of Groundwater Recovery by Recharge in the Agricultural Area

The Kumamoto area, Kyushu, Japan has 1,041km in area and about 1milion in population. This area is a greatest area in Japan which depends on groundwater for all of drinking water. Quantity of this local groundwater use is about 200MCM during the year. It is understood that the main recharging area of groundwater exist in the rice field zone which have high infiltrate height ahead of 100mm/ day ...

Comparison of Small Area Estimation Methods for Estimating Unemployment Rate

Extended Abstract. In recent years, needs for small area estimations have been greatly increased for large surveys particularly household surveys in Sta­ tistical Centre of Iran (SCI), because of the costs and respondent burden. The lack of suitable auxiliary variables between two decennial housing and popula­ tion census is a challenge for SCI in using these methods. In general, the...

Impacts of climate variability and changes on groundwater recharge in the semi-arid southwestern United States

Impacts of soil conservation on groundwater recharge in the semi-arid Loess Plateau, China

Soil conservation measures undertaken to address land degradation can alter the hydrologic cycle by changing partitioning of water fluxes at the land surface. While effects on runoff are well documented, impacts of soil conservation activities on fluxes to groundwater are poorly understood. The goal of this study was to examine fluxes to groundwater in a semi-arid area of China’s Loess Plateau ...

Groundwater modeling for estimation of the recharge rate and identification of appropriate recharge sites in Damghan Plain, Iran

Water is the main option of any development, so having an accurate management of groundwater is necessary. This study has been done in Damghan sedimentary plain in Iran, which is located in northwest of Semnan Province. The main objective of this research was to estimate the rate and right site of recharge in Damghan plain to prevent the aquifer from decreasing the water table. For this purpose...
