Yam peel was used as adsorbent, prior washing, drying, size reduction, and selection. The experimental work consisted in determining the effect of bed depth, particle size, and temperature, keeping inlet flow = 0.75 cm 3 ∙s –1 , pH = 2 and initial concentration of 100 mg∙dm –3 . The Adsorption Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray (EDS) analysis on yam ( Dioscorea rotundata ) peel showed a heterogeneous, porous structure, with functional groups characteristic in lignocellulosic materials. It was analysed regarding the influence of temperature, bed height, and adsorbent particle size on the removal efficiency; it was found that the decrease of particle size and the increase of the bed height favour the elimination of the metallic ion, with removal rates between 92.4 and 98.3%. The bed maximum adsorption capacity was 61.75 mg∙g –1 , and break time of 360 min. The break curve’s adjustment to the Thomas, Yoon–Nelson, Dose–Response and Adams–Bohart models was evaluated, concluding that the Yoon–Nelson and Dose–Response models best described the behaviour of the break curve with a coefficient of determination ( R 2 ) of 0.95 and 0.96, respectively. The results show that the bio-adsorbent studied can be used to eliminate Cr(VI) in a continuous system","PeriodicalId":39224,"journal":{"name":"Journal of Water and Land Development","volume":"451 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135637129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The simulation of wave propagation along the El Arab River under several scenarios was performed by the hydraulic HEC-RAS model. This model is dedicated to the description of floods at the dam following a breach in the dike. The main factors considered in this simulation include the level of flood water, the flood hydrograph, and the typical scenario for this breach. The flood risk analysis revealed that the maximum of flood wave flow registered at the breach is (Qmax = 9253.02 m∙s), and is beginning to mitigate downstream of the dam along the El Arab River where it reached at the last village with a low flow (Q = 1110.64 m∙s). This simulation allowed drawing the risk map which showed the areas threatened by flood wave resulting from a total failure of the work, and consequently required a plan of security measures to moderate as much as possible the consequences of floods. A sensitivity analysis was conducted to approach the parameters of impact of the breach on the dam failure scenario. It was confirmed that these parameters as formulation time, breach width and side slope have a great influence on the dam failure scenario with the four adjustments (±20 and ±50).","PeriodicalId":39224,"journal":{"name":"Journal of Water and Land Development","volume":"430 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135637146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aquatic neighbourhoods become a field of experience for residential architecture, where traditional systems are enriched with new elements and solutions. Some of these solutions can be brought back to the sys-tem and improve the overall catalogue of answers for the development of traditional dwelling. The analysis discusses contemporary housing projects 1998–2005 and includes: the program overview, basic numerical parameters, accessibility details and relation to the context. Current water-related examples are accompanied by a reference to standard solutions developed in the modern era. All presented designs use traditional components of dwelling program, grouping day zone elements and separate them from private spaces. In basic parameters development is visible in bigger areas of living space. In terms of accessibility housing on or close to water gives new opportunities, as well as in relation to the context. The paper presents research on different types of dwelling located by the water, with particular emphasis on functional and architectural advantages, which may be used to improve contemporary housing models.

Sandy filters are the most commonly used industrial filters in surface – and groundwater industries. The reason is their low construction cost and high processing capacity. In our scientific research, sand filters used in the plant do not have perfect filtration, so we can monitor results before filtration (BF) and after filtration (AF) by determining the concentration of some ions and molecules. The following average concentrations have described: Ca (BF: 83.42, AF: 83.19) mg·dm, Mg (BF: 35.59, AF: 34.35) mg·dm, Cl (BF: 28.018, AF: 28.73) mg·dm, SO4 (BF: 42.76, AF: 44.46) mg·dm, HCO3 (BF: 410.9, AF: 404.81) mg·dm, A-HCl (BF: 6.73, AF: 6.63) ml-HCl, GH (BF: 19.94, AF: 19.62) °dH, CS (BF: 18.87, AF: 18.5) °dH and NO2 (BF: 0.0033, AF: 0.0022) mg·dm.

Additionally, one of the most important quality parameters studied in the quality of water resources of dams and reservoirs is the study of water quality in terms of salinity. The salinity of the reservoirs is primarily due to the rivers leading into them. The control of error in the reservoirs is always considered because the outlet water of the reservoirs, depending on the type of consumption, should always be standard in terms of salinity. Therefore, in this study, using the available statistics, the Ce-Qual-W2 two-dimensional model was used to simulate the heat and salinity layering of the Latyan Dam reservoir. The results showed that with warming and shifting from spring to late summer, the slope of temperature changes at depth increases and thermal layering intensifies, and a severe temperature difference occurs at depth. The results of sensitivity analysis also showed that by decreasing the wind shear coefficient ( WSC ), the reservoir water temperature increases, so that by increasing or decreasing the value of this coefficient by 0.4, the average water temperature by 0.56°C changes inversely, and the results also show that by increasing or decreasing the value of the shade coefficient by 0.85, the average water temperature changes by about 7.62°C, directly.","PeriodicalId":39224,"journal":{"name":"Journal of Water and Land Development","volume":"545 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135637368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phosphate bacteria (PB) was inoculated into sterile Andisols in three separate compositions, termed 1 kg P∙kg (2.82 g phosphate rock, 0.5 g Ca3(PO4)2, 0.4 g Al3(PO4)2, or 0.4 g Fe3(PO4)2), organic P (0.5 cm para-Nitrophenylphosphate (pNPP) or 0.5 g Na-phytate), and 1 kg P (KH2PO4)∙kg, in order to analyse inorganic P solubilisation, organic P mineralization, and evaluate blocking soil colloidal site for adsorption P, respectively.

Abstract MIKE SHE software was used to estimate recharge into the aquifers of Ogun and Oshun Basins. Abeokuta within the Ogun Basin and Oshogbo in the Oshun Basin are sub-divided vertically into two components: atmosphere, and unsaturated zone. The atmosphere zone comprises of rainfall and potential evapotranspiration, while the unsaturated zones, comprises of the Basement Complex and Sedimentary rock. Daily records from two rainfall stations, Oshogbo station (2008–2011) and Abeokuta station (2010–2014) water years were obtained for simulation of groundwater recharge processes using MIKE SHE model. The simulation results showed that daily groundwater recharge is influenced by rainfall and ranges from 0 mm∙day –1 in January when there was an insufficient rainfall in the two stations to 10.89 mm∙day –1 in Abeokuta and 29.85 mm∙day –1 in Oshogbo in the month of August when the soils had attained field capacity. The study found out that there are more daily groundwater recharge in Oshun basin compared to that of Ogun basin. This was alluded to more rainfall and less evapotranspiration recorded at Oshun basin as compared to Ogun basin coupled with the sedimentary soil which allows more movement of water into the aquifer of the basin.
