Adongo TA, Kyei-Baffour N, Abagale FK, Agyare WA. 2019. Assessment of reservoir sedimentation irrigation dams in northern Ghana. Lake Reserv Manage. 36:87–105.Sedimentation reservoirs is a serious issue that threatens their functionalities. Since information on this phenomenon Ghana almost nonexistent, study was necessary. The used bathymetric survey integrated with geographic systems (GIS) tools to assess 9 3 regions conducted during August–October 2017 using hand-held Hondex digital depth...

Landuse alteration is a critical factor that exerts influence over hydrological mechanisms and the oversight of water resources across globe. Northern Ghana characterized by erratic rainfall, leading to intense construction small dams dugouts. This study investigated historical landuse/cover (LULC) changes physical factors associated with surface runoff generation within eight (8) sub-catchments namely; Guno, Gbahali, Sambu, Duago, Denugo, Kwisini, Sandu, Nyeko, areas 29.5, 110, 38.5,...

Water shortages, exacerbated by erratic rainfall, climate change, and population growth, pose significant challenges globally, particularly in semi-arid regions like northern Ghana. Despite the construction of numerous small dams region that were intended to provide reliable water for domestic irrigation purposes, critical issues persist during dry periods. Key drivers this failure are attributed lack studies and/or number inadequate on suitable dam siting. This study focused assessing sites...

The review explored various flumes used for open channel flow measurement and provided insight into operational concepts, discharge measurement, range of flow, head loss requirements, degree accuracy submergence, advantages, limitations use. reviewed included; Parshall flumes, Montana Cutthroat H-flumes, Trapezoidal Replogle-Bos-Clemmens (RBC) Palmer-Bowlus Central Baffle (CBF). Based on the stage relationship, have a reasonable ± 10 % over wide flows. RBC are most accurate (± 2 %). For...

Municipal waste management has been of major concern to many developing countries and is presently one the subjects under discussion due rapid industrialization population growth. Most these municipal wastes have potential being recycled use in crop production. They are gradually becoming a problem Ghana instead used for purposes benefit human kind. In this study, dried faecal sludge co-compost was as an organic fertilizer cultivate cabbage lettuce assess its effects on their microbial load...

Abstract Effective management of reservoir sedimentation requires models that can predict the reservoirs. In this study, linear regression, non-linear exponential regression and artificial neural network have been developed for forecasting annual storage capacity loss reservoirs in Guinea Savannah Ecological Zone (GSEZ) Ghana. Annual rainfall, inflows, trap efficiency age were input parameters whilst output parameter was sediment volume Twenty (20) years data with 70% used model training 30%...

ABSTRACT The study was carried out in the northern Ghana to estimate water inflows nine reservoirs of irrigation dams for a period 20 years (1999–2018) using USDA Natural Resources Conservation Service Curve Number model. key input parameters model were hydrologic soil group, rainfall amount, landuse/landcover, weighted curve number, antecedent moisture condition, and potential maximum retention. annual within reservoir catchments found vary between 617.20 1,382.30 mm. estimated runoff...

Food insecurity in Ghana is major challenge the country, with a significant portion of population (5%) facing risk inadequate access to food. Whilst there food insecurity, agricultural productivity country not increasing. Additionally, farming especially northern fully depends on rainfall. Also, farmers are faced climate crisis such as drought and high temperatures which affects productivity. Alternative ways fertigation have been demonstrated increase many parts world. However, this...

Fresh water resource is one of the most significant natural assets a country. Irrigation dams are usually used for irrigation purposes and also often serve as source domestic use. Due to this, there need proper maintenance, assessment, sustainable use dams. This study assessed physicochemical properties in reservoir Bontanga dam situated Guinea Savannah Agro-Ecological Zone Ghana. The four (4) physical fourteen (14) chemical quality parameters know whether they within acceptable threshold...

The experiment was conducted for two (2) seasons i.e., dry and rainy seasons, with the aim to evaluate yield of lettuce when kraal manure, sheep droppings compost fertilizer is used as soil amendment, determine effect each treatment on water use efficiency. treatments were droppings, applied at 60 t/ha. result showed that growing using 3 significantly affected its stem girth, number leaves, individual weight above ground biomass weight. Lettuce grown amendment found have higher in terms...

The study assessed performance and state of water retention infrastructure eight (8) irrigation schemes in three (3) northern regions Ghana. Data was collected using field observation key informants’ interviews. results indicated that the Tono Bontanga earthen dams’ embankments had no structural defects whereas Libga, Golinga, Karni, Vea, Doba Sankana some defects. Except all spillways deficiencies signs risk failure. All reservoirs contained amounts sediments weeds. night storage at Vea...

CROPWAT 8.0 model was used to estimate the water requirement of pineapple for 2021/22 cropping period, considering all months in year. This done ascertain which year have lower irrigation requirements and where savings can be made. For December August, (mm) 140, 145.1, 113.3, 110.8, 110.9, 145.9, 107.6 114, respectively determined at study site. However, sucker planting September, October November has shown 72.8, 61.3, 61.4 respectively, adjusting calendar accommodate these is recommended.

This study was carried out at Fihini in the Tolon District to investigate influence of integrated use poultry droppings/rice husk biochar co-compost and sulphate ammonia on growth yield maize different planting distances during 2015 raining season, from July October 2015. The experiment laid a randomized complete block design with four replicates treatments: PD1 - 20 cm x 80 cm, PD2 30 PD3 40 PD4 50 cm. Relevant crop parameters were measured soil moisture content also monitored periodically...
