Randublatung groundwater basin is one of the groundwaters basins with massive utilization of groundwater pumping. However, the knowledge of the comprehensive hydrogeological system in this groundwater basin is limited, so this research aims to determine a comprehensive hydrogeological conceptual model of the Randublatung groundwater basin. The methodology was conducted by collecting secondary and primary data of deep and shallow wells to evaluate boundaries of pattern and direction of groundwater flow and develop the aquifer system’s geometry. The result shows that the groundwater flow boundaries are Grogol River in the west, Wado River in the East, Bengawan Solo river in the South as a river boundary, and Rembang Mountains in the North as a constant head boundary. Therefore, groundwater flows from the hills area to the Bengawan Solo River and the north as the river’s flow. Based on the log bor evaluation, the aquifer system of the study area consist of an unconfined aquifer with a maximum thickness of 20 m and three layers of confined aquifers with thickness vary between 8 to 60 m. the hydraulic conductivity of the aquifers depends on the aquifer’s lithology range from sand, gravel, limestone, and sandstone. This hydrogeological conceptual model provides essential information for numerical groundwater models in the middle of the Randublatung groundwater basin.

The high groundwater use in the Randublatung Groundwater Basin area relates to groundwater abstraction for agriculture. Therefore, a question arises on how much groundwater resources in this area may support agricultural groundwater usage. This research has the objective to quantify the groundwater resources in this area. This research conducts a geoelectrical investigation to identify the aquifer’s lithology and observe the groundwater level. The research reveals that resistivity values of subsurface rock layers in the research area range from 0.13 to 124.86 Ωm. The aquifer layer consisted of two aquifer systems, with the hydraulic conductivity varies of the aquifer layer is 0.0001 cm/s until 0.01 cm/s. The aquifer layers estimated to be found at depths vary 5 – 90 m from the ground with thickness range from 10 to 70 m. Meanwhile, the aquiclude layers consisted of clay, silty clay, and sandy clay was estimated to be found at depths varies 0 – 50 m from the ground with thickness varies from 5 to 65 m. by combining those data with a hydraulic gradient of groundwater flow, the dynamic groundwater resources in the research area is estimated between 50 m3/day and 4,691 m3/day.

Abstract A quantitative analysis of the depositional processes on the Mahakam Delta indicates that it is presently subsiding and is, in essence, a drowned delta that is being transgressed and modified by marine processes. Calculations of sediment transport rate indicate that most, if not all, fluvially derived sand is being stored onshore in the distributaries, whilst finer-grained sediment moves offshore. A fining-upward and increasingly marine-upward succession is being deposited in the distributaries, which is analogous to nearby outcropping and subsurface successions that have previously been interpreted as progradational. The mixed fluvial and tide-dominant shoreline morphology is not solely a product of the deltas present-day processes. The fluvial component is a relict feature from a phase of progradation that preceded the ongoing transgression and is now being modified by tidal processes. Facies distribution is a much better indicator of modern depositional processes than delta morphology on the Mahakam Delta, suggesting that facies-based delta classifications are more accurate than morphology-based classifications. All the apparently anomalous components of the sedimentology and morphology are reconciled by a transgressive interpretation, including the overly deep distributaries, gently dipping subaqueous delta plain, penetration by benthic marine organisms far into the distributaries, widespread Nypa palm on the lower delta plain, and the long, mud-filled gap between sand in the distributaries and on offshore bars.

Water is very crucial for surviving life of all human being and animals. Without water nobody can be survived. The existing manuscript associated with Anchar Lake water. Water is vulgarized by unwanted materials. Water quality tests and reevaluate of attributes. Scrupulous substances are: Dissolved Oxygen (DO), Total Alkalinity(TA), Electric Conductivity(EC), Potential of Hydrogen(pH), Phosphate(P), Total Dissolve Solids(TDS) , Total Hardness(TH) and Chloride thereupon. The attributes are statistically interpreted using Cluster Analysis, Correlation matrix, factor Analysis and ANOVA techniques and interpret that the Lake water is unsuitable for drinking. Experimental data shows that most of the attributes does not satisfy the desirable limits prescribed by BIS. Hence the Anchar Lake water is not suitable for drinking purposes.

In this work, we used reflexive Banach spaces to study the differential variational—hemivariational inequality problems with constraints. We established a sequence of perturbed differential variational–hemivariational inequality problems with perturbed constraints and penalty coefficients. Then, for each perturbed inequality, we proved the unique solvability and convergence of the solutions to the problems. Following that, we proposed a mathematical model for a viscoelastic rod in unilateral contact equilibrium, where the unknowns were the displacement field and the history of the deformation. We used the abstract penalty method in the analysis of this inequality and provided the corresponding mechanical interpretations.
