High groundwater recharge potential zones occur in the central part of the study area within the generally flat flood plains consisting of alluvium lithology.

A geological study revealed that two main rock types, sandstone and shale, characterize the study area. The shale does not yield enough water, while the sandy area is the water-bearing zone. The sandstone outcrop trends N 55°E, dipping 160°SE with a dip of 60°, which facilitates the downward water motion by gravity. The presence of highly fractured and jointed sandstone is another attribute of the porous Afikpo sandstone in the Owutu-Amaigbo area. All the sample sizes are moderately sorted and moderately well sorted, with the exception of the sample at 120 ft. that is poorly sorted. At 90 ft., the sample is strongly positively skewed at 30 ft., 120 ft., 180 ft., and at the surface. At 60 ft., 150 ft., and 210 ft., they are nearly symmetrical. The samples are very coarse sand, except at 30 ft. and 210 ft. From the VES data, the aquifers were delineated between layers 3 and 4, ranging in depth from 50 to 60 m.

Improper pharmaceutical disposal is common in many countries, from home to hospitals. The review shows that, despite the presence of regulations and rules in developed and developing countries, this practice is still growing. Apart from the ecological effects of pharmaceuticals in the environment, antibiotic resistance is more likely where germs such as bacteria and fungi develop resistance to the drugs designed to kill them. One of significant source of pharmaceuticals into the environment is improper disposal. This review shows that improper pharmaceutical handling and disposal is a challenge in all East African countries. This poses a risk of environmental contamination, human health and developing antibiotic resistance. There is a need for more awareness enhancing, policy review and enforcement of laws to protect both human and environmental health.</p></div>","PeriodicalId":100615,"journal":{"name":"HydroResearch","volume":"5 ","pages":"Pages 99-107"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2589757822000087/pdfft?md5=5fce8106fff2bdda08969fa3d3c393b4&pid=1-s2.0-S2589757822000087-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72978772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 122 sub-surface water samples were collected from the Amroha district of Uttar Pradesh, India, in the pre and post-monsoon season 2018 (61 samples of each season). The quality of groundwater observed from the study region has a slightly acidic to alkaline character with moderately hard type water. The order of the dominant ions is Na⁺ &gt; Ca²⁺ &gt; Mg⁺ &gt; K⁺ and HCO⁻₃ &gt; Cl⁻ &gt; SO₄²⁻ &gt; NO⁻₃ &gt; F⁻ in the pre-monsoon season while Na⁺ &gt; Mg⁺ &gt; Ca²⁺ &gt; K⁺ and HCO⁻₃ &gt; SO₄²⁻ &gt; Cl⁻ &gt; NO⁻₃ &gt; F⁻ in the post-monsoon season. A few samples show a higher concentration of Nitrate and Fluoride. The correlation coefficient shows that EC is positively correlated with TDS, Cl⁻, Ca²⁺, Mg⁺, and Total Hardness. The WQI studies revealed that about 52.45%, 36.07%, and 11.48% samples denoted excellent, good, and poor water quality, respectively, in the pre-monsoon season. About 52.45%, 45.9%, 1.63% of groundwater samples fell under excellent, good, and poor water quality in the post-monsoon season. The Piper diagram depicts Ca–HCO_3, mixed Ca-Na-HCO3, Na–Cl, and mixed Ca-Mg-Cl facies in the water samples. Chloro-alkaline indices show negative values, which indicates that most parts of the study area exist in the discharge zone and base ion exchange processes occurred in the area. The position of the sample on the Gibbs diagram revealed that the rock-water interaction and evaporation of dissolved formation are the major governing process of water chemistry. Irrigation water quality indices revealed that the water quality for irrigation uses is mainly excellent to permissible type. The result of the Corrosivity ratio shows that about 24.5% of groundwater of the study area can be transported only through PVC pipes.</p></div>","PeriodicalId":100615,"journal":{"name":"HydroResearch","volume":"5 ","pages":"Pages 54-70"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2589757822000051/pdfft?md5=d07d58dea2e4f7a1541f6bf1480d42b2&pid=1-s2.0-S2589757822000051-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82527532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Though identifying the relationships between catchment attributes and model parameters is straightforward, the uncertainties in both model parameters and functional relationships lead to poor regionalization. The key to successful regionalization is selecting a parsimonious model structure, proper catchment attributes, a better calibration strategy, and a proper regional model structure. The parameters of the HYMOD model were calibrated from 59 watersheds across the globe using a three-year calibration period and evolutionary algorithms, which are well-suited to account for the multiobjective nature of hydrological model calibration. The optimized parameter set satisfactorily reproduced the observed flow for all catchments used to calibrate the regional models. Over the calibration and validation period, the optimal regional relationship obtained from the multiple polynomial regression (MPR) and the multiobjective regional calibration (MORC) methods were developed and evaluated. For basins used for calibration of regional relationship, the performance loss of the model simulation with parameters estimated from the MPR and MORC methods was 14% and 10% respectively. The performance loss for basins presumed ungauged was 15 and 12.6% for MPR and MORC respectively.
