In response to the escalating global demand for energy resources, the exploration and utilization of diverse energy sources have garnered substantial attention over the past decade. Among these resources, coal bed methane has emerged as a promising energy reservoir, sparking interest in its extraction feasibility and efficiency. This study conducts a comprehensive comparative analysis of the Maiganga coal bed, aiming to assess the practicality of extracting methane gas from this field while evaluating the recovery process’s efficacy. The investigation encompasses a meticulous examination of a spectrum of factors that influence methane gas extraction and utilization from the coal bed. This comprehensive analysis involves intricate evaluations of geological characteristics, reservoir dynamics, and pertinent technological advancements driving methane extraction techniques. The research findings provide profound insights into the potential volumes of gas that could be harnessed or simulated over a 25-year horizon. Evaluating two well orientations—vertical and horizontal—the study predicts remarkable gas volumes. The vertical well orientation is estimated to yield 6501.8 MMSCF (Million Standard Cubic Feet) of gas, thereby indicating a significant potential contribution to the global energy landscape. The horizontal well orientation, however, reveals even greater promise, projecting an impressive gas volume of 19866.1 MMSCF over the same time frame. Beyond the scope of production volumes, this study places a focal point on determining recovery efficiency associated with the extraction processes. The results underscore the impact of technological choices on resource recovery, showcasing a recovery efficiency of 4.99% for the vertical well orientation and a more substantial 15.2% for the horizontal well orientation.

Geoid is an equipotential surface of the earth rotation. It is currently available worldwide with the Earth Gravitational Model (EGM 2008), but generalised for locality. Apart from geoid determination being one the problems of the geodesy, the generalised EGM 2008 need to be tested before usage in a particular locality and a times geoid prediction is required. This study aimed to compute the geoidal undulations of the study area using Satlevel Collocation Model with a view to produce the geoidal map of the study area – Akure Ondo State, Nigeria. The methodology include determination of ellipsoidal and orthometric heights from Differential GPS and geodetic levelling with application of orthometric correction respectively. Geoidal coefficients for the “Satlevel” Collocation Model were computed from the mean corrected global residuals using the Least Squares adjustment as well as computed geoidal values of the points from adjusted observations to enable prediction of geoidal values through interpolation for other part of the study area where the values were not acquired. Tables were produced to show the relationships of the ellipsoidal heights, orthometric heights, the local geoid, and geoidal undulation computed for new Satlevel Collocation Model. Finally, the geoidal map of the study area is produced using AutoCAD Civil 3D. The variation of Geoidal Undulations not accounted by the Satlevel model were computed and shown in a Table. The results satisfied 95% significant level. This shows the reliability of the ‘Satlevel’ Collocation models when points are evenly spaced and well distributed. It is therefore recommended for usage in any purpose for geoid determination.

Sediment transport is most often used to determine whether erosion or deposition will occur, the magnitude of this erosion or deposition, and the time and distance over which it will occur. The combination of fine and coarse grains was used to investigate the movement of sediment particles. Transport of grains occurs when instantaneous vertical component of flow exceeds the settling velocity of the particles. Fall velocity in still water is influenced by two sets of forces: Submerged weight of the particle, and viscous fluid resistance and inertia effects. Small and big particles behave differently: for small particles, viscous resistance dominates; inertia is negligible. for large particles that fall quickly, inertial forces dominate. Coarser-grained sediment (typically sand and gravel) transported on the bottom of the channel bed by rolling and sliding. Fine-grained sediment (typically clay and silt) transported in suspension due to turbulence. The deposition of the incoming sediment reduces the storage capacity of a reservoir over time, and affects the effective management of the structure. Good management of sediment in dams will have economic benefits and reduce environmental impacts.

This study assesses and analyze the aquifer yield characteristics of shallow wells in Kumbotso Local Government Area, Kano State, by leveraging geologic data. The research utilizes recuperation (recovery) tests. The grid sampling technique was employed, resulting in forty-five (45) sampling points. However, only three (3) points located at Challawa axis lacked wells due to the presence of hard rock formations. The study assessed aquifer variables included specific yield per unit area, well discharge, and flow velocity. The results revealed that the northern and eastern parts of the area were situated at very high altitudes, with the elevation gradually decreasing from the northern to the southern part. High and moderate groundwater elevations were dominant in the dry season, each accounting for 30.96% of the area, while high groundwater elevations dominated during the wet season with 40.48%. The specific yield per unit area of the wells in the region had a mean of 0.75 M3/h, with the medium class being dominant at 59.52%. The mean discharge of the wells in the area was 87.74m3/h, with low discharge classification being dominant at 57.14%. The mean flow velocity in the study area was 3.71 m/h (6.18 cm/min), and the area was predominantly classified as having medium flow velocity, accounting for 61.90%. Furthermore, the sub-surface soil formations of the aquifer indicated that fine sand had the highest percentage at 59%, followed by coarse sand at 36%, and clay formation with only 5%. Sub-surface soil formations composed of sand and fine gravels were identified as good aquifers due to their high transmissibility (water-carrying capacity), whereas clay formations contained sufficient water but had a limited capacity to transmit water. The study recommends the implementation of geophysical surveys before establishing wells to ensure successful water resources exploitation.

This paper examines how resilient design can contribute in mitigating the negative effects of flood disasters. The objective of the paper is examining the contribution of architectural design in flood mitigation. The study adopts qualitative approach, data collected were from secondary sources and participant observation. The study found heavy rainfall and the release of water from dams as contributing factor to the flooding in Nigeria and particularly the study area Idah. The study identifies inadequate drainage system in the affected area and indiscriminate building without permit. Conclusively, the identified strategies in mitigating flood impact as indicated in the literature can be consider for implementation in the study area. Therefore, this study recommends the adoption of the non-structural strategies in mitigating the effects of flooding in the area. The structural strategy is to form criteria of the town planning and development authority for any property developers seeking for approval. The planning authority should not allow request for plan permit without resilient attributes in the design.
