“…Sediment penetration resistance was measured in situ using a hand penetrometer (IB, 6000 kN•m −2 , Eijkelkamp). Indoor measurements for saturated hydraulic conductivity can be obtained using constant or variable-head tests [40]. According to [41], the variable-head test is the most suitable for finely grained soils, while the constant-head method is best suited for coarse-grained soils.…”

“…e mean sediment pH values were 6.30 and 6.61, respectively, for the surface and sub-surface horizons. An association between somewhat acidic conditions and farming would have existed in the watershed area where agricultural activities are the main land use [40]. e pH of the sediment may have been caused by weathering reactions and mineral composition as a result of erosion and deposition processes [55].…”

“…Furthermore, oxidative weathering, acid rain, fertilizer use, and excessive rainfall would all have contributed to the somewhat acidic conditions [55]. Water circulation in the deposit area might have had an impact on the pH fluctuations in both horizons [40]. e mean electrical conductivity, on the other hand, was 0.39 dS•m −1 for both the surface and subsurface horizons.…”

“…It is a primary soil parameter that cements soil aggregates, thereby enhancing their stability [52]. e presence of organic matter in the soil is a good indicator of the soil's health status since its effects are manifested in its different properties and functions [40]. Undecomposed organic material that appears on the soil surface helps in the dissipation of the kinetic energy of the rainfall drops, while the highly decomposed material (humus) binds the soil particles [50,58].…”

Energy and water are the two most important natural resources in the globe. In this regard, dams and reservoirs are the critical hydraulic structures that store water and, above all, provide energy required by humanity. However, water storage and the provision of energy by reservoirs and dams have been disrupted by significant environmental changes taking place in the catchment areas and the reservoir environment. These disruptions are brought about by climatic parameters and sediment transport by different eroding agents. One such environmental problem is soil erosion, whose effect is reservoir sedimentation. Consequently, a part of the transported sediment is deposited at the catchment outlet, which serves as the reservoir inlet. This study was carried out to establish the physicochemical characteristics of the deposited sediment at the reservoir inlet. The following parameters were analyzed: particle size distribution, organic matter content, bulk density, porosity, electrical conductivity, penetration resistance, hydraulic conductivity, pH, and nutrients (nitrogen, phosphorous, and potassium) using standard laboratory procedures. The study established that the deposited sediments were predominantly sand particles with mean values of 50.60% and 58.60% for the surface (0–10 cm) or sub-surface horizons (10–20 cm), respectively. The average values for sediment pH, organic matter, porosity, bulk density, electrical conductivity, penetration resistance, hydraulic conductivity, and nutrients were 6.30 and 6.61; 1.91 and 1.80%; 54.10 and 57.10%; 1.22 and 1.14 g·cm−3 for the surface and sub-surface horizons, respectively. The most variable parameters were silt content (sub-surface horizon), hydraulic conductivity, penetration resistance, electrical conductivity, nitrogen content (surface horizon), and phosphorous (surface horizon) content with CV >0.35. Based on the present study results, the deposited sediments at the reservoir inlet were found to have low concentrations of nutrients and high sand proportions. Therefore, the deposited sediments appear to have great potential to reclaim the immediate barren dam environment upon enrichment and to promote sand harvesting programs for economic benefits.

“…In addition, the adaptability, growth, and reproduction of aquatic species are also subject to the quality of water and sediment [22] of the concerned habitat. Considering the importance of sediment nutrients for aquatic ecosystems, several studies on different water bodies such as beels [23,24], aquaculture ponds [25], lakes [26], micro-basin [4], rivers [27][28][29], channel [30], and estuary [31] were conducted. Despite their relevance in the coastal region of Bangladesh, extensive research on the dynamics of nutrients and the physical features of sediments from homestead ponds is lacking.…”

Homestead ponds are small seasonal ponds that are rarely utilized for fish farming. Culturing fish in these small ponds can boost household fish consumption and cash inflow. The availability of nutrients in the water and sediment, however, plays a significant role in the pond’s natural productivity. This study was conducted to assess nutrient contents and some key physical parameters in the bottom sediments of 30 homestead ponds from the central coast along the Northern Bay of Bengal. Analyses of results showed the average values (±SD) of temperature, pH, electrical conductivity, organic matter (OM), organic carbon (°C), nitrogen (N), phosphorus (P) and sulphur (S) were 17.8 ± 1.12 °C, 7.29 ± 0.11, 0.41 ± 0.09 mS/cm, 29,615.48 ± 10,528.9 mg kg−1, 11,958 ± 6107 mg kg−1, 1030.6 ± 252 mg kg−1, 17.1 ± 13.5 mg kg−1 and 32.6 ± 19.7 mg kg−1 during winter and 27.2 ± 1.81 °C, 6.73 ± 0.12, 0.38 ± 0.17 mS/cm, 19,100.01 ±13,739.07 mg kg−1, 11,079 ± 7969 mg kg−1, 955 ± 229.4 mgkg−1, 26.6 ± 20.2 mg kg−1 and 23.4 ± 15.9 mg kg−1 during pre-monsoon, respectively. One-way ANOVA revealed no significant differences in the mean value of sediment quality parameters among the selected ponds (p > 0.05) except for phosphorus in the winter season (p < 0.05). The sediment quality variables were found to be in the suitable range for fish culture. Pearson’s correlation coefficient values (r) showed that only organic carbon and nitrogen had a strong significant correlation with organic matter (p < 0.05). Based on Cluster Analysis (CA), two major associations among the nutrients were attained at a 15% similarity level: C, OM, and N in one cluster and P and S in another. The findings showed that the parameters were within the preferable range for aquaculture, and the homestead ponds are average productive ponds.
