In this article, a hybrid model is proposed to quantify the rate of groundwater recharge using new hybrid model tack in interest the annual rainfall and the average annual temperature and the geological characteristics of the area.Abstract:
Deficiency of surface water resources in semi-arid area makes the groundwater the most preferred resource to assure population increased needs. In this research we are going to quantify the rate of groundwater recharge using new hybrid model tack in interest the annual rainfall and the average annual temperature and the geological characteristics of the area. This hybrid model was tested and calibrated using a chemical tracer method called Chloride mass balance method (CMB). This hybrid model is a combination between general hydrogeological model and a hydrological model. We have tested this model in an aquifer complex in the region of Djelfa (Algeria). Performance of this model was verified by five criteria [Nash, mean absolute error (MAE), Root mean square error (RMSE), the coefficient of determination and the arithmetic mean error (AME)]. These new approximations facilitate the groundwater management in semi-arid areas; this model is a perfection and amelioration of the model developed by Chibane et al. This model gives a very interesting result, with low uncertainty. A new recharge class diagram was established by our model to get rapidly and quickly the groundwater recharge value for any area in semi-arid region, using temperature and rainfall.read more

Trend Analysis and Variability of Air Temperature and Rainfall in Regional River Basins
TL;DR: Doi et al. as mentioned in this paper examined the variability of air temperature and rainfall in the five states of South-Eastern region of Nigeria, using the trend analysis approach and found that the trend of rainfall is decreasing for all the study areas in South-East with the lowest trend rate of -0.1153 mm rainfall occurring in Umuahia.

TL;DR: The conceptual model provided in this study could be used as a reference for porous aquifers submitted to high rainfall amount and the determination of natural background levels (NBLs) and threshold values (TV) of chemical components in groundwater to assess the contamination for different flow paths can be beneficial to improve groundwater resources management.

Root mean square error (RMSE) or mean absolute error (MAE)? – Arguments against avoiding RMSE in the literature
TL;DR: In this article, the root mean square error (RMSE) and the mean absolute error (MAE) are used to evaluate model performance and it is shown that the RMSE is more appropriate to represent model performance than the MAE when the error distribution is expected to be Gaussian.

TL;DR: It is concluded that aquifer degradation is much more than a localized problem because the sustainability of the resource base for much of the rapid socio-economic development of the second half of the twentieth century is threatened on quite a widespread geographical basis and major investments in groundwater resource and quality protection are urgently needed.
